I'm trying to setup a cisco 871W as a wireless router. It has an external IP, a gateway provided by our ISP, and two DNS servers. I can ping domains and IPs from within the router (via telnet), but I can't pint anything but the internal and external IP addresses of the 871W when connected through the WLAN or any fast ethernet port. I've tried to use SDM express and Cisco Configuration Assistant to get it working and can't seem to get it to pass any network traffic.
Here's my configuration. Any help would be greatly appreciated. This is my first cisco experience.

In essence, you can substitute my DNS servers with yours (where it says eq domain) and then i have 2 time servers alowed in. you can omit this if not using NTP to synch your clock. Bootps and bootpc is for the DHCP to be able to dish out an IP for my FA4 interface from comcast. If you have a static IP from your ISP omit this. The line:
access-list 105 deny ip 192.168.0.1 0.0.0.255 any
is very important and needs to be there so you dont block your own subnet. To implement the ACL do this
