877W - problem


i have a problem with 877w.

i have some pc's connected to the fast interfaces and dsl is up and running.

pc's can surf ( via nat on the dialer interface ).

now , on the wireless part , i configured auth (mac address) and enc + dhcp pool + nat on the dhcp pool.

i am connected with my pc to the router by wireless and got an ip , i can ping the router dot1radio ip address but not outside to the internet.

ping from the router it self - with source ip of the dot1radio address is working so NAT is good.

what am i missing ? do i need briding ?
