DHCP via wireless

hypnotoad

Guys,

I never have to configure wireless interfaces in routers, I only do it on APs...Can anyone tell me why the clients (successfully connected to the wireless) wouldn't be able to get an IP address?

Thanks. I'm working remotely on this, which makes troubleshooting wireless more interesting.

I've not worked with it, but I'd guess at the fact that the Dot11Radio0 interface has no IP, and therefore isn't taking part in Layer 3. I don't see any reference to it using another interface (say, via IP unnumbered or something like that)

Could be.

Try giving your clients a address and gateway manually as the DHCP server would assign. Can you ping the gateway?

Yeah, except I cant figure out where to download this template spreadsheet he made.

Well, I can't imagine setting an IP on dot11radio 0, since I'd need to find a new subnet so it doesnt overlap with fast 0/4...so I don't think that's it.

You can set up a Bridged-group virtual interface (BVI) here is a resource that may help on it Understanding and Configuring VLAN Routing and Bridging on a Router Using the IRB Feature - Cisco Systems. Also I see you have a start of a ZBF (Zone-Based Policy Firewall - Cisco Systems) that could give you some issues.

I think you're right on the BVI (and probably the ZBF too). This is pretty much a fresh load and I kind of assumed I could get by without creating an BVI for some simple stuff.
