Cisco Firewall :: ASA5505 Disable DHCP On ASA And Enable On WNDR3700
May 13, 2013
I have ASA5505 as my main router (192.168.15.1) and it currently it also serves as DHCP server. I have a WNDR3700 (192.168.15.2) which work as an access point and it provide wireless access for wireless devices. I have few dhcp clients where i can't setup static IP, and i want to restrict them to use static IP through MAC reservation.
1. Make ASA5505 to do the MAC reservation f, which will be easy setup for me. But as per my search its not possible.
2. Disable dhcp on ASA and enable dhcp on my WNDR3700. i tired this and dhcp clients are getting IP from wndr3700, but the problem is dhcp clients gateway defaults to 192.168.15.2 (as well as dns) and therefore no internet connection.

I have a ASA5505 that i have running asdm 6.4 on it and have tried setting up some DHCP scopes for the interfaces.I have the security plus key.I set up 4 interfaces all with different subnets and all with different DHCP being doled out by the firewall for the time being.Anyway, 3 of the 4 work.I have tried to change interfaces wondering if there was an issue with that phy device.I tried enableing the subnet that would not work first and it didnt matter still would not issue dhcp.the other 3 work fine.Is there a limitation to the amount of scopes that will issue dhcp for an asa5505 ?

My cisco representative tells me that I am limited to 10 IP addresses for my 10 user license on an ASA 5505 even though the Cisco documentation specifically states that a 10 user license allows the maximum DHCP clients to 32 IP addresses.
I want to have 30 computers get IP addresses from the ASA, but don't need any but one or two to get outside the internal network. Is this possible with a 10 USER license.

I received WAP4410N-G5 AP with 2.0.2.1 firmware and set up it very easily. Never experienced a single signal drop in a few days.
After updating firmware to 2.0.4.2 version I am completly unable to make any changes! If I press on "Enable" or "Disable" all settings will be lost after I apply them and neither "Enabled" nor "Disabled" is selected.
Had to revert back to 2.0.2.1. Is my AP faulty?

In my ongoing project i need to monitor cisco 3750-X port status (uplink/downlink) i.e. whenever there is some problem at a specific port. I need to monitor it through an OPC server and right now what i am doing is as follows: i am using Kepserver and i have added SNMP driver in it for that purpose i am not a networking expert but what i have learnt till now is that SNMP agent (that resides in switch) delivers the status of MIBs to SNMP manager ( which in my case is kepserver (opc server)) for the above purpose i am adding IF-MIB to monitor OID 1.3.6.1.2.1.2.2.1.8 (which shows port statuses) but when i add that in OPC server then it indicated that this OID is not available in the Switch ( it might be disabled) so i need to ask if there is any way to enable OID's in a switch,

I have an EA6500 wireless router and i have to constantly disable / enable the guest wireless access to get it working again. It might work some time less than a day but then it fails. I tried to set the wireless channel manually instead of auto and the same issue is happening. The private wireless ssid works just fine. I have the latest firmware.

I'm in a bit of a predicament. Trying to set up a Netgear WNDR3700 behind a SonicWall TZ170 SP (Standard OS). The only thing I really want the SonicWall to do is maintain site-to-site VPN connections to a few other networks that I work with.
The SonicWall WAN is passing Internet connectivity to the LAN ports as it is supposed to but the hangup seems to happen at the Netgear; it doesn't seem to want to receive Internet connectivity from anything but a modem and it doesn't want it going to any port but the Internet port (IE, it doesn't seem to want to share Internet via the switches).
I'm thinking this may be a limitation of the firmware and that dd-wrt might be the only answer but I thought I'd bring it here first as my last experience with dd-wrt wasn't a good one.

I've purchased a router SRP547W and I would disable DHCP server. On the control panel I can't see anything about disabling this function. I don't need dhcp server on router and I don't need dhcp relay. My firmware version is 1.2.4_003.

We have an SRP541W on which I thought I had disabled DHCP, its turns out that in fact I haven't. After seaching again for the DHCP on/off funtion I found it under the Vlan settings (Wierd place to put it I thought).
The Router has a static ip address on the LAN side of 192.168.1.254 and is connected to a Cisco 2700 series on the WAN side. Our network DHCP is served by an SBS 2011 server hence my reason to switch off DHCP on the router. However when I select Static IP address from the Address Type in the VLAN settings and try and save the changes I get an error that is IP Address / Subnet Mask value is illegal. Great but why when the router has and IP address assigned and the subnet mask is set do I get this error. On the VLAN settings page there is no option to set an IP Address

The operation steps on router (WRVS4400N):
1.Set the IP mode as Dual-stack IP and then save
2.Disable the IPV4 DHCP server
3.Use other deivces to connect the router.
The connected devices have the same IP address(2005:123:456:789::1),I am confused,why is it?

Can you confirm that if I want to disable temporarily a dhcp pool on a 4500, I need just to shutdown the interface VLAN corresponding to a specific dhcp pool?
ip dhcp pool test

How to disable dhcp proxy on controller and what is the impact of doing it in the middle? We tried once by giving 'config dhcp proxy disable' command but seeing virtual ip again.(likely it gets back to proxy mode). We also have ip helper address on the L3 interface. We have only external dhcp servers configured..

I have a BEFSR41v2 and have since upgraded to a wireless router. I now need a hub and have read that I can disable the DHCP in the BEFSR41 and use it as a hub. If I understand what I've read, I hook the cable running from my current wireless router into the uplink port on the BEFSR41 and then have the 4 ports available for expansion without using the WAN port - does this sound correct? Also - should I have the router (now configured as a hub) set to obtain the IP address automatically, set a static IP address or what? Finally - the firmware is the original firmware 1.42.7 (April 2, 2002) and I've read where people have problems after updating the firmware.

I have a new customer that I installed an ASA 5505 to replace a Linksys VPN router. They have a main office with a static IP address, 3 branch offices with static IP addresses and 2 branches that are doing DHCP from the ISP for their router address. I have no problem getting the static VPNs up and running. My problem is with the VPN connections that are doing DHCP. I can go in and determine what IP they are currently using and setup a connection and it works fine. The problem is of course when their IP address from the ISP changes, which seems to happen at least daily. What is the proper way to setup a connection that is using DHCP? Also, can you setup multiple connections this way? Currently the 2 locations have different passwords setup in their routers.
