Increasing Number Of Addresses And Dhcp Address Range
Dec 2, 2011
A small network and uses the Linksys Router BEFSR81 as dhcp.the default Number of addresses is 50 and starts 10.0.0.100 to 10.0.0.149.A new Cisco IP Phone just introduced requires ip addresses and have noticed running out of addreses.Can I increase the number to 120 so that the address range would start from 10.0.0.100 to 10.0.0.219, also, I have a VPN device which automatically configures itself for 10.0.0.199 address and this is /24 network configuration.

How can i configure DHCP to use two different range of IP addresses. One range will be for example 192.168.0.* and the other range will be 192.168.1.* When the first range of ip is full the DHCP automatically assign IP addresses from the second range.

I keep getting some additional IP addresses logging onto my home network that have an address outside what should be allowed by the router. The server is running at 192.168.2.1 and is set to only allow clients from 192.168.2.2 - 192.168.2.10 so a total of 9 clients should be allowed on.The problem is that something keeps logging in with an address of 192.168.169.2 or 3 etc. Sometimes more than one device at a time.I have assumed that it is some automated or virtual client as I'm pretty certain my network has not been breached. I have a 9 character password with a relatively random alphanumeric combination, although I haven't tried changing the password (I live in a share house with with a bunch of devices using wireless, so I haven't yet bothered). What I don't understand is how it has connected with the xx.xx.169.xx range at all. I have a Belkin 'Share' Wireless N Modem Router and at some stage there was a 'guest' network but that has since been disabled and I still am seeing the extra address. I have attached a screen shot of the DHCP client list on the router.The following is a list of devices that may be on the network at times, I'm thinking one of these may be responsible for the problem:
Windows Vista Desktop - Only LAN device
PS3
Macbook
Epson wireless printer
Android HTC Desire Mobile Phone
Laptops running various Windows versions (XP, Vista and 7)
A few thoughts I had:
- the android phone is capable of running a wireless hotspot, may have to look into it to see if if has been operating as an access point into the Belkin router, but assumed this wouldn't bring up clients connected to the phone on the home router.
- The desktop has PS3 Media server installed to stream video to the PS3 over the network (not that I have ever managed to get it to work), however this is not ever open on the desktop.

Using Android phone and have to set up Port Forwarding to access the cameras. I have to change the IP Address to a static one instead of the one issued by the Router. How do I change the IP Address of the camera to one outside the DHCP range?

I found increasing number of overrun in the tengigabit interface. The hardware is 6509 with sup720-3B and the overrun output is shown in WS-X6716-10GE module. The connected device to WS-X6716-10GE is EMC Islion S200. I think the capability of WS-X6716-10GE can handle EMC NAS device and the load is not so busy. So I have no idea of handling this and the reason why this overrun packet is shown.

we have a 3560 switch configured with EIGRP with dhcp. We have a user that we cannot ping, however the interface show up / up and no errors on interface. the ip address is 10.2.0.199 - however we have dhcp configured to exclude the range from dhcp ip dhcp excluded-address 10.22.0.1 10.22.0.200 how can this work station get a dhcp address if we have that ip range excluded from the dhcp pool?
The user is off a different switch that is a uplink to this distribution switch. Traceroutes shows that the problem is with the distribution switch.

We frequently camp at campgrounds that offer free WiFi, but many campsites are on the fringe of receiving a signal. Is there anything I can add to my laptop to increase receiving range- ie usb adapter with antenna?

E4200v2, firmware 2.1.39.145204
Router says "Invalid IP address" when I try to make a manual IP address reservation of the IP address range.
Example: local network 192.168.1.0/24, where .1 is a router, .2 is a reservation, .20-.50 is a range for DHCP.
Before upgrade I didn't have this problem.

I am having a very strange issue with connecting new machines to reach the internet.We have a ASA 5505 which the previous tech configured the DHCP pool to 192.168.1.60 - 192.168.1.110
We ended up reaching our limit which I changed it to: 192.168.1.60 - 192.168.187
Then next day when I arrived to work, our DC was hung from windows updates. Once we got everything back up, every computer currently on the network can reach the internet/VPN tunnels etc. So (continuing with my day) I created a new server in a VM (Hyper-V)I can ping everything internally (even the router) 192.168.1.1, but I cannot resolve DNS. I have configured a static IP, tried Dynamic IP.I have looked for any ACL indicating to block outside the range of the old DHCP pool but no luck.On my local maching I can ping the DNS addresses, but just not on the new server.

There is nice c2900PortNumberOfLearnedAddresses table in C2900-MIB, but it's outdated and not supported by modern switches.Is there similar table for modern switches? Most interested in Catalyst 2960 and 3750.

I need to know the maximum number of MAC addresses that can be entered in to the MAC security filter list on the AP541N.I know it has a maximum number of 200 concurrent users, however the documentation does not specifiy whether this also applies to the MAC filter.
I have used wireless acces points in the past that allow hundreds of users but only allow 64 MAC addresses, so this is very important.

trying to configure our ASA 5505 (hence my request for the ASDM). However, I can go CLI if push comes to shove.
What I'm trying to do is allow a range of IP addresses on the inside interface (those which the DHCP server is doling out IPs which are XXX.X.XXX.14-140) to access email only (which is hosted offsite). They still need to access the file servers which are on the inside but nothing should be going out to the internet other than email.
I believe I have to create a Network Object which contains the IP range I wish to restrict. I can see where I add the Network Object but I don't know what the syntax should be to specify the address range.
I'm also not sure what the sequence of the ACLs should be and whether or not I can keep the default Access Rules in place. There are the two implicit rules: 1) Permit any traffic out to less secure networks 2) Deny any traffic to anywhere (which is superceded by rule 1, yes?)
To create an Access Rule like the one I desire, do I need to move the two existing rules down the list so that the new one will supercede both implicit rules?

I've just installed a 2106 Controller at a remote site. The Controller is seen by the WCS at the main site so, connectivity is good and I'm able to login from the main site. I've configured the DHCP server which is at the Main site on the AP manager interface and the Manager interface and on the WLAN of the new controller but, APs are not getting addresses.

Netgear DG834 allocates IP Addresses using DHCP to 5 computers and 2 tills, the tills addresses and one computer IP addreess are reserved and fixed, so that data can be downloaded from the tills to this computer. However I had to re-format the computer and the Router now allocates a new IP address to it, which the tills cannot recognise, so I cannot download the data from the tills to the computer. Is it possible to change the newly allocated Computer IP address in the Router back to the old one.

I have a Belkin model F9K1102 router supplying WAN/LAN connection to three PCs and 2 laptops. Two of the PCs are hardwired with the remainder PC and laptops are wireless. I'm using the default router IP of 192.168.2.1 and my ISP is Charter Cable (if that's of significance). The router is picking up all the dynamic IP information from my ISP and internal DHCP is enabled. Here's the issue though - when I connect a PC, laptop or iTouch (wired or wireless) with obtain IP settings automatically enabled the IP address it receives an IP address on a different subnet ie, 192.168.3.x and thus won't have WAN/LAN connection. I have tried to set the router IP to 192.168.3.1 and set the scope in the .3 subnet but the IP obtained by the device is .4! This makes no sense to me at all. The router is on the latest firmware (according to Belkin) and there doesn't seem to be any other update I can find. I have also tried another Belkin router (older model: F5D8236) and it does the same thing.
I'm not sure if this is related but I upgraded my service with Charter to a 18MB connection and a D3.0 Ubee cable modem - this issue seem to have began after this upgrade but I don't see how that would have any bearing on what is happening on my LAN IP scope and Charter tech support is pretty useless. My workaround is that I've static assigned an IP for each device in the same subnet as the router but it would be nice for the DHCP to function correctly.

I imagine I can use the framed-ip-address attribute to assign ip-addresses but there seem to be support for static ip addresses only?A bit of a drag when we're talking 200+ nodes.

Initially there were 3 SSIDs configured but all of them were assigned a single interface and this interface was configured with the controller management IP address as DHCP server so that the WLC could assign IP addresses to wireless clients, guns and printers etc.
Issue: As part of PCI initiative, we decided to segment the traffic in multiple subnets based on type of wireless clients; so now there are 3 interfaces configured and each SSID is assigned a specific dynamic interface and each interface is configured to use the controller management IP address as DHCP server.
There are 3 scopes configured for each of the dynamic interfaces/SSIDs and DHCP proxy is enabled but wirelss clients are still being allocated IP addresses from the original DHCP scope that was associated with the dynamic interface originally assigned to all 3 SSIDs.
I verified the following:
1. Each SSID is assigned a different dynamic interface (Users, Voice and Handhelds)
2. Each dynamic interface is configured to use controllers management IP address as DHCP server
3. DHCP scopes configured with correct network information for each dynamic interface and enabled

I have a LAP1142N that is connected to a 3560 nonPoE switch (using compatible power injector) that will not associate to the controller I have set-up. The wireless is existing and I have about 11 other APs connected to the controller with no issues. The AP will pull an IP address from DHCP running on the primary controller. The AP pulls a new IP address in roughly a minute. I set the pool to be 3 IP addresses and set a contant ping to each, there is about 1 request time out before the next IP address starts pinging. I went to the controller and pulled the following message error from the log.
*Feb 13 14:24:58.614: %LWAPP-3-HDR_ENCAP_ERR: spam_lrad.c:4216 Unable to encapsulate LWAPP header for discovery response; AP (APs MAC address)

I have tried a different cable, connecting to a PoE switch, different controller, larger DHCP range, hosting DHCP on the distribution switch, I am awaiting console access to the AP since this is remote work. The controller is running Software Version 5.1.151.0. Thoughts?

I currently have a the following configuration and am unable to get more than 2 DHCP addresses for the devices connected to the Cisco new SG 100-16 Switch.The AP have no trouble handing out DHCP to the wireless clients, but we are unable to get the SG 100-16 to be able to do the same thing to wired clients. It is currently connected to the 2960-8 in port 1. We can get 2 devices connected without a problem, but the 3rd machine and beyond do not work. Also, setting up a static IP does not work. Using a static will not even allow us to ping or tracer back to any devices beyond the SG 100-16.

I have a few sites using the RV042 with wireless access points and some of them have over 50 devices.In reviewing the documentation (specifically,[URL]), I came across this:Enable DHCP server: Check the box to allow the router to dynamically assign IP addresses to up to 50 connected devices. Uncheck the box if you have another DHCP server on the network or you want to configure static IP addresses for your network devices.Is this accurate? Or will the RV042 allow more than 50 devices?

I have a wireless access point, I want to be able to hand out addresses via the Cisco router through DHCP on the interface eth0/1. The wireless users that get an IP I want then route out the eth0/0 interface to my statically assigned default gateway. Right now Im not concerned with setting up security measures once this works I'll go back in and add that. Here is my running-config. Right now nothing from the 10.0.0.0 is being routed out to the internet.

I have a LAN with about 200 computers (192.168.10.0/24) with a DHCP Server on Windows server 2003.The problem is that my company have acquired 100 others computers that I have connected on this network.Some computer does not get IP address from the DHCP server. When I investigated the log of the DHCP server, I realized that the DHCP server was out of addresses.
