I have a situation in which i have cisco 1841 router running IOS 12.4c with two fast ethernet ports and one WIC1T card .Now we have leased line configured. i want wireless to work as a back up for leased line.(wireless is also internet).
i will terminate into one Fa0/0 for RF,but now my problem is that i have a PIX 506E behind from router running version 6.3(the outside interface Ip is of Leased Line with All the Nat configured in PIX )which is Fa0/1(to pIX).....is it possible to do backup ?if yes then how?
