WLC 2106 + DNS

Unanswered Question

Hi,


having no problems to get the AP's attached and configured via the WLC, but i'm not able to get the DNS-resolution in the LAN done proper.


That means: Having 3 AP's connected to WLC2106, this one is getting it's DNS for one SSID/VLAN from an external DHCP-Server - works very well. If you are connected via a real copper-cable to the VLAN, you'll get the DNS-resolution (put up an ip name-configuration on the DHCP-Server which is a cisco-switch) but via wireless - no chance.

Tried all versions of changing the default-gateway or DNS-Server (directly to the DHCP, where the ip-name-resolution is lying) - nothing.


What the hell? :) It seems really to be a wireless-problem. Allthough i can use external DNS-Servers to get in the internet but getting a local (LAN) solution would be preferrable...


regards :)

Lets step back for a moment if we may, im a little slow this morning with no coffee :)


So you have a 2106 and you can not get the access points to join the controller or you can but you are having DNS issues once a client joins?

Try turning off dhcp by proxy. I am assuming you are using an external dhcp scope.


config dhcp proxy disable


Insure that the gateway address for the interface in the wlc is correct as well. Make sure the dhcp scope gets the proper dns entries as well.
