ATM—>212.X.X.X
MT RB333-----> 10.9.X.X
AP---------->10.9.X.X

i want to provide intenet from ATM to client.

just i want to know how can i give ip address and routing for that .
can anyone give me example or configuration?

i really need help for that.

thanx in advance

you will have to nat on the 333 board and the rest of the net will have to be bridged to make the setup you have layed out work
