Cisco VPN :: Configuring DHCP Reservations For VPN Users Terminating On ASA 5540

Mar 7, 2011

I have an ASA 5540 cluster that is configured as my remote access VPN point. Users connect using IPSEC Profiles with Cert based authentication, the profile is configured to query two DHCP servers (infoblox appliance servers).
 
The problem I am encountering, is that I need to make reservations on the DHCP server for some users for specific business needs. What happens is that the ASA passes the request to the DHCP server with it's own MAC address and not the MAC of the remote host.
 
Is there any way I can configure the ASA to pass the request using the hosts actual MAC address?

Cisco Firewall :: DHCP Reservations With ASA 9

Nov 15, 2012

how to setup DHCP reservations I found that the ASA 8.x was unable to do it but saw reference that ASA 9 was supposed to have this feature. Looking thru 9 and asdm 7 I'm not seeing how to. I know it just came out but I can't find any official mention of this feature in 9.

D-Link DIR-615 :: Formation Regarding DHCP Reservations List?

Jan 2, 2012

I have a DIR-615 router running FW version 3.01 with Hardware Version: C1 , my xbox is wired to my router. When I port forwarded, i had an strict nat, but had the best connection, but not by very much. When i put DMZ on, i had a strict nat, and the connection to other people was a bit better then UPnP.When i had UPnP on i had a open nat, i could barely be able to connect to anyone.what is a DHCP Reservations List?

Linksys Wireless Router :: DHCP Reservations On E1200?

Feb 8, 2012

I'm setting up a new E1200 and I'm searching for the area for DHCP reservations. My D-Link DIR-615 offers this ability in the Admin panel. This is quite useful since it allows for easier port forwarding management to specific Machine IPs without having to assign static IPs for each machine. I can't seem to find any documentation on this feature no the site or in the forum that applies to the E1200. If it's not offered, boy did I make a mistake in getting the E1200. I should have bought another DIR-615.

D-Link DIR-825 :: DGL-4500 MAC Address In DHCP Reservations List

Jan 13, 2010

I have a setup using LogMeIn Hamachi and the network type creates a Windows Bridge. I also use the DHCP Reservations List to assign the same IP to specific devices. Well I have the MAC Address for my NIC in the list which works when I am not using the bridge. When using the bridge, of course the MAC address changes and when I try to add it to the list I get the following message in a popup window. The MAC Address is 02:e0:61:05:45:3e I have tried manually entering it, letting the router enter it from the list of computers and just to rule out something stupid, I have tried changing the letters to upper case and removing the colons.

Another issue I can see when this issue is resolved is that I do not believe it will let me add this reservation since I will be using the same IP used by another reservation. My DGL-4500 allowed this if I had the other reservations using the same IP disabled.Below these comments/rants are some feature requests. I have put them last as some of the requests are explained in the comment/rant section.I have read through this list and I have to say that after I purchased the router, which I ordered on-line, I was dreading it, but I have not had issues. It is possible that I am not using features that cause this issue. I believe the issues occur when using certain configurations with the "Enable Advanced DNS Service" enabled. I am not using this service. Since I knew people were having issue s with it, I wanted to see my results leaving that out. I have had this router running since a week before Christmas and I have many Virtual Server entires, QoS and port forwarding entries, https based remote administration, both 5GHz and 2.4GHz networks enabled supporting a/b/g/n(on both networks) and a guest network enabled on both bands all supporting WPA (TKIP and AES). I have 2 Giga wired connections that are always active, a 100Mb connection that is on an off but used almost daily, 2 Laptops that use the 2.4GHz network daily and one is 802.11g 54Mb and the other is 802.11n 150Mb and they are on at the same time almost daily, a printer that is on and used multiple times a week that uses 802.11g and a game system that uses 802.11a this device is used daily. Most devices are on and used at the same time daily and we have a good deal of regular Internet traffic and moderate other network traffic during these times. At night all computers are backed up over the network and most of the other network devices are off or not during this time. Other than having to reboot my Internet hardware provided by my ISP, I have not had issues. The router has been rebooted for config changes and I usually cycle it when I cycle the Internet hardware. Point is, so far no issues, good performance and it works and I have of course had other devices connected using the guest network and I have been testing features, performance, etc.

What's up with having so much variation in how features work across routers?e.g. My DHCP Reservation issue above. This router does not work with a setup like my DGL-4500.This router allows a preset amount of services like QoS and Virtual Server entries while the DGL-4500 just lets you add entries. Now maybe there is a limit and it just looks like there is no limit. Of course, there is at least a limit that is reached when you have used a certain amount of memory with the configuration.so many routers while leaving gaps and the lack of feature explanation and comparison?I switched to this router because I wanted a dual band setup which my DGL-4500 does not provide. That leads to the issue of the new way D-Link deals with dual-band. When I purchased the router it did not list that you had to choose 2.4GHz or 5GHz or it is not simultaneous dual-band. I was duped because I used to install DWL-7100AP for people that needed better wireless options for home businesses and small businesses and that provides simultaneous dual-band and back then if it was dual-band it was simultaneous. But I am disappointed in some of the features lost like WISH support and a few options here and there which do not seem like they are specific to gaming routers and this router is more on the mid range and low high range end of consumer, prosumer, home business and lower traffic small business routers, so why is it missing these features and why does it have the limitations I listed in the "variation in how features work" section above?

Other examples of lack of feature clarity are with Game Fuel, HD FUEL and Intelligent QoS. Isn't Game Fuel Intelligent QoS of some sort. Now from the example provided in the overview for the DGL-4500, Game Fuel optimizes game performance, but it does not say this is automatic or if it works along with the rules you set in the Game Fuel section which is the same as the QoS Engine section in the DIR-825. The difference is that the DIR-825 has a "Enable QoS Engine" option while the DGL-4500 has an "Enable Game Fuel" option. It seems that Intelligent QoS does what Game Fuel does, but expands that to VOIP, Media Streaming, etc. and it may be more automatic. HD Fuel in the only place I have seen it mentioned seems to refer to the combination of Intelligent QoS and the inclusion of 5GHz wireless support. Of course there is no version and feature documentation and in fact while the overview of the DIR-825 talks about gaming with Intelligent QoS, but if you bring up a comparison of routers, the chart has no in the gaming section for the DIR-825. I can't say I have noticed better or worse gaming performance with the DIR-825 compared with the DGL-4500, but given the shear lack of documentation on how to use Game Fuel and Intelligent QoS properly, who knows if I have this setup correctly. I will say the QoS Engine section in the DIR-825 is easier to use than the Game Fuel section in the DGL-4500.

1) The ability to reduce the brightness of the status lights, set them to solid if enabled with brightness options and to set them to off with an option to have some very faint light to show that the router is on. Of course I should be able to set different options to be applied at specific times.

2) Add the applicable features missing from the DIR-825 that are found in the DGL-4500 and applicable features from other routers. Also, get them all so they work the same on each router and let get the best from them all and make that the standard. e.g. In my DHCP reservation example above don't set the standard to the limitations of the DIR-825, but make the DGL-4500 function set or better function set of all routers combined for each feature the standard with-in router categories. e.g. the DIR-825, DGL-4500 and DIR-855 would be in the high end router category for consumer, prosumer, home business and lower traffic small business routers.

3) For DHCP reservations, you should not be limited to the DHCP IP Address Range.

4) On the log-in screen, get a better captcha and fix the tab order.

5) Add a log-out option in the web interface.

6) Allow for a next hop option in the DCHP server section. It would be cool, if there could be a list of IPs allows one to be enabled at a time.

7) Allow different DHCP server settings for each network. There are 5 on the DIR-825. Wired, 2.4GHz regular, 2.4GHz Guest, 5GHz regular and 5GHz Guest. Would be nice if you could set a couple of VLANs on the Ethernet ports and then have different DHCP setings for each VLAN.

For guest wireless networks, allow rules to be set to allow access to certain services on the network. E.g. I may want to allow printing. So allow a single port or multiple ports with easy settings for consecutive port ranges to be opened to an IP, IP range or all IPs and allow all ports for an IP or range of IPs. Of course, leave the allow full access option.

8a) Allow users to set rule sets that can be enabled/disabled like the full access option.

8b) Allow a control that can be set in the rule sets that controls if the wireless devices can talk to each other and another that controls if they can access devices on the wired network and another that controls if the wireless devices can access the Internet.

8c) Allow rules above to be limited to be applied to specific MAC Addresses.

8d) These options would be good to have for the non-guest wireless networks and wired network as well.

Cisco Switches :: SG300 DHCP Static Reservations Are Not Working

May 19, 2013

I'm having troubles with this firmware in a SG300-28 switch. Actually the DHCP server, a new feature in this firmware release, doesn't work correctly. DHCP static reservations are not working: CLient ID and MAC address are not recognized correctly, and the DHCP server assigns the first free IP in the pool, rather than the reserved one.If Cisco engineers read this, plese correct the issue.

D-Link DIR-655 :: Schedule Rules Is Full / When Adding DHCP Reservations

Feb 19, 2012

This is on a DIR-655, firmware 2.01NA, hardware rev B1.Is there a limit on the number of DHCP reservations that can be added to this WAP?This WAP was working fine with 10 DHCP reservations (wired & wireless devices), 6 schedules, Access control of 2 devices by MAC (6 defined, only 2-3 active at a time).I started adding additional DHCP reservations, because I'm simplifiying my network, and when I add the 26th DHCP reservation I get the message "Schedule rules is Full! Please Delete an Entry."

I've been adding all of the new DHCP reservations as disabled, but I haven't assigned any schedules or otherwise to these new devices yet. So what's up with this message??

D-Link DIR-615 :: Hosts Specified In DHCP Reservations List Can Access Network?

May 1, 2011

1. To specify static IPs for components on my network, is it simply a matter of reserving each component in the DHCP Reservations List portion of the Network Settings page?

2. On the same page, in the DHCP Server Settings portion, if Enable DHCP Server : is deselected, does this mean that only the hosts specified in the DHCP Reservations List can access the network? In other words, is access now restricted to these entries?

3. If the DIR-615 is powered OFF, will the above settings, etc. be lost (similar to a reset)?

Cisco Switching/Routing :: 891 Router DHCP Server Reservations Being Overridden?

Dec 11, 2012

I am running into a DHCP problem on a Cisco 891 running 15.0(1)M2.  I am running DHCP on the router and want to reserve an address for a printer.  I have done this hundreds of times on hundreds of routers.  Per Cisco recommendation, I let the printer lease an address to see whether it uses it's "hardware-address" or "client-id".  This printer uses the "hardware-address" format.  The printer has leased 10.0.0.102 right off the bat.  I want it at 10.0.0.50.
 
I have a DHCP pool, like this:
 
ip dhcp pool CLIENT
   network 10.0.0.0 255.255.255.0
   domain-name chsinc.ds
   default-router 10.0.0.1
   dns-server 10.0.0.1
   lease 2
 
I create a "reservation" like so:
 
ip dhcp pool HP_LaserJet_Printer
   host 10.0.0.50 255.255.255.0
   hardware abcd.ef12.3456
 
Now I do a "show running-config" to see what I've put in and it looks just like above.  Now we reset the network settings or change any network setting on the printer to force it to renew it's lease.  What should happen and what usually happens is that the printer should request an IP, be offered 10.0.0.50, accept that IP and come up on that IP address.  What is happening with this particular printer is that the printer requests a specific IP (the same IP that it had initially = 10.0.0.102), the router says OK and does not enforce the reservation.  Then the router actually deletes the hardware-address config line right out of the running config.  A "show running-config" shows that the reservation config now looks like this:
 
ip dhcp pool HP_LaserJet_Printer
   host 10.0.0.50 255.255.255.0
 
See the logs below.  Notice the ones in bold.
 
000226: Dec 12 17:34:01.382: DHCPD: Seeing if there is an internally specified pool class:
000227: Dec 12 17:34:01.382:   DHCPD: htype 1 chaddr 101f.74b0.575c
000228: Dec 12 17:34:01.382:   DHCPD: remote id 020a00000ae1e10100000001
000229: Dec 12 17:34:01.382:   DHCPD: circuit id 00000000

[code]....

Is there a way to make the router enforce the reservation and not let clients just bring their own IP and actually make changes to the running-config of the router?

I have an EA2700 running latest firmware 1.1.38.138827. It is using Cisco Connect Cloud. I am unable to access the DHCP Reservations link under Connectivity/ Local Network. When I click on it, nothing happens. I've tried multiple browsers including IE 10 (Windows 8 RTM), Firefox 15, and Chrome 21. I also tried on a Windows 7 machine with IE 9 and the link doesn't work on that either except that it shows a box that says Invalid Character when I click on the DHCP Reservations link. I see no invalid characters on the screen. Any workaround other than downgrading the firmware or assigning static IPs on individual PCs?Also, on an unrelated note, where is the Dynanic DNS configuration on the Cisco Connect Cloud?

Cisco VPN :: ASA 5540 Remote VPN With DHCP Failing

Feb 28, 2013

I am currently running an ASA5540 version 8.3(2). I have multiple remove vpn users currently working on this server. Lately, I have had issues with people getting booted or not being able to route anywhere and it appears to be cause they keep fighting for the same IP address using the local pool, so I decided to attempt to do DHCP instead (I have no idea why it keeps overlapping IPs, we have tons in the pool and they keep fighting for the same one). This just started about a month ago, we are only using maybe 3-5 IPs out of the /24 block. The only thing that has changed was we have hired more people, but we have separate groups for corporate vs operations team.
 
So, I setup the dhcp-network-scope for the subnet and the dhcp-server under the policies. I see the request going to the server, but it seems to be putting the ASA MAC into the Client Hardware Address field of the DHCP header. I have attached the PCAP from the ASA showing this.

Cisco WAN :: Configuring 851 With PPPoE And DHCP

Aug 29, 2011

Trying to find a way to configure my 851 for home use. My internet provider use PPPoE with PAP and althrough I found many configuration options they all are incomplete...or i cant find the logic behind those commands. First of all I need to say what I need:

1. Configurate my int Fa4 (WAN) with pppoe so when i insert my ISP cable in it it will negotiate and take IP.

2. Configurate DHCP on LAN (Fa0-3) so that when I insert my PC it will take a fake IP.
 
Here is the place where i found some conf examples: [URL] and I have some questions:

1. MTU - Should I use the 1492 value or the "pppoe-client ppp-max-payload 1500"?

2. ip route 10.10.25.2 255.255.255.255 dialer 0 - How can i set an IP route when my connexion informations only come after i connect? (Because is PPPoE)?

3. I cant configurate the DHCP because I dont know the default route, I dont know the DNS, and i dont know the default gateway because I dont know them due to PPPoE !

Cisco :: 4402 - Sluggish DHCP For Guest Users

Feb 3, 2011

Our Guest access system seems to be having problems with DHCP. It seems to take a while to deliver an IP address making the client device show the "limited or no connectivity" message, which of course makes the users complain. On one occassion I have seen my own client eventually picking up an address even after the limited connectivity message appeared. On another I saw the debug showing "Dhcp request for autoconfig address", which I suspect is a symptom of the problem.
 
Our Anchor Controller is the DHCP server and is a 4402 running 7.0.98.0 - I've attached some DHCP packet debug.

Cisco Routers :: RV220W Max DHCP Users (Max Connections) Per Vlan

Nov 19, 2011

We assign (reserve by MAC actually) static IPs to all of our devices.  Over time we have gotten rid of some devices but haven't begun (or finished really) re-using the old IPs.  On our WRVS4400N v2 routers we are able to set the max number of DHCP users per Vlan.  This prevents unauthorized devices trying to connect to our LAN.For example.  I set the range from 192.168.1.100 - 192.168.1.103.  IPs 100, 101, and 103 are in use (reserved via MAC address).  We set max number of DHCP users to 3.  This prevents someone from gaining access to 192.168.1.102.  Does this make sense?  Or at least this was the initial goal and it tested out successfully back when we implemented it.
 
How can I do the same for with the RV220W?  I can set the range, assign static IPs (reserve IPs by MAC address), but can't keep others from gaining accessing to our LAN via the unused IPs (not assigned a static IP).My initial thought was to create static IPs (for the unused IPs) using dummy MAC addresses.  I'm sure there is a much better way of accomplishing what I am trying to do.

Cisco Switching/Routing :: Nexus 7010 New Users Were Not Getting Ip Address From Dhcp Server

Jun 8, 2013

We  have 2 nexus 7010 switches configured with HSRP in the network. For all  the vlans core1 is Master and Core2 is standby. In the current setup we  have external dhcp server and dhcp relay is configured for all the  vlans on Master and standby switch. The setup is running the IOS 5.2
 
Activity Done: During  the Maintainacne activity, we isolated core1 switch in the network by  disabling the vpc/keepalive and all the uplinks from access switch. The  core2 switch was master for all the vlans.
 
Issue observed: It  has been observed that new users were not getting ip address from the  dhcp server. The ethereal capture showed that dhcp server was not  getting the dhcp requests from the core2 switch. We disabled the dhcp  feature in core2 and enabled again with dhcp relay again configured on  vlan interfaces .even after doing this no change was observed in  behaviour. Finally we got core1 back in network by enabling all the  links.
 
Observation: The  moment VPC link came up between the core switches, users started  getting ip's from dhcp. Then we started enabling all the uplinks on  core1.Core1 again become master for all the vlans and users continued  getting ip’s. Network running fine.
 
Further Testing

1. For  one of the vlan, core 2 switch has been made primary and for new users  checked the dhcp functionality and it was working fine. The aim was to  identify if anything wrong on core 2 related to dhcp relay

2.Again  we changed the priority for this vlan and made core1 master for the  same. This time we disabled this vlan on core1 and tried new user with  core 2 became master and dhcp functionality worked fine for new user.  Actually in this case we have simulated the same behaviour when we  observed the issue with only difference of VPC was not available during  the issue time as core 1 was isolated form network 
Inputs needed.

Is  there any known behaviour for dhcp functionality when VPC is  unavailable? If we see the test scenario2 (wherein core1 was master for  the vlan and we disable this vlan on core 1 and core 2 was able to relay  dhcp requests for new users in this vlan.) it was actually same as  scenario we observed during issue time..

Epson WF2530 - Configuring Network Wi-Fi Printer From Ubuntu With DHCP

Mar 4, 2013

I'm trying to use an EPSON WF2530 printer over wifi from my laptop Everythings fine until the printer gets turned off and on and the router assigns a new (different) IP address via DHCP.

I can run:

sudo nmap -PR -sP 192.168.1.1/24

which returns a list of MAC addresses and IP addresses on the LAN and then manually set the printer properties to the new IP address or I can log into the WiFi router and inspect the DHCP table then do the same thing What I'd really like to be able to do is have Ubuntu handle this automatically, e.g. it queries the MAC addresses on the LAN, finds the printer, extracts the current IP address and sets the printer properties appropriately? have to check the printers IP address every time I want to use it.I don't want to go down the route of having a static IP table

router is Cisco Linksys Dual-Band Wireless-N ADSL2+ Modem Router with Gigabit WAG320N

Cisco Switching/Routing :: Catalyst 4500 - EtherChannel Terminating On Different Line

Apr 22, 2012

I have 2 x WS-X4548-GB-RJ45 Catalyst 4500 Enhanced 48-Port 10/100/1000 Base-T (RJ-45) line cards in a 4500 chassis with 2 x WS-C4507R-E E-Series Super visor engines. We would like to create a layer 3 ether channel from a access layer switch terminating on our 4500 chassis. Can we configure the ether channel from the access layer switch such that one port on the ether channel is on one line card and the other one is on the other line card?
