We have a cisco 837 router setup to handle internet and a backup wan tunnel at a small remote office. We want to use the DMZ port in the 837 to put a wireless access point there so it would be seperated from our internal network. Inside LAN can get out to the internet fine and the site-to-site tunnel works fine, but wireless traffic cannot reach the internet. We can ping the dmz interface, but cannot access the internet. Attached is the config. Any suggestions.
