We have a private network using a frame relay connection (10.x.x.x). Also we have dsl connection (192.x.x.x using NAT)I want to intigrate the internet network in 10.x.x.x network. what kind of configuration on our cisco router must be done? so that our work station can access the 10.x.x.x network and also can access the 192.x.x.x. network ( Internet using NAT) simultanously.
