Cisco 871 Wireless

I figure I am missing some small but important detail here. I have a

871 router with wireless with the advanced security IOS. Any wired connection works just fine. I can get an IP address from a Windows DHCP server and ping any internal address. However, I can not ping the vlan interface IP address nor get to the Internet. Below is the relevant part of the config.

Thank you.

I believe your fast ethernet interface needs to be part of the bridge-group 1...

try buting the vlan1 Ip address on the BVI interface along wiht the ip nat inside

Very strange. I just configured the 2nd unit configuring the BVI 1 interface with an inside IP address instead of vlan 1. Everything worked fine. I will have to re-visit the first one and see what I missed.

The above config is fine provided you implement Mervs suggestion.

Thank you.
