I have a 2524 with a T1 connection from ATT. The internal csu/dsu, (S0) has an IP address, 12.127.x.x that belongs to ATT. Now, this is routed to my IP block 12.54.x.x/29 that I got from ATT. What I want to do is translate this 12.54.x.x/29 to a private netblock,192.168.1/24. The question I have is, do I need another router to do this or can I do it with the one router?
