I have two Cisco 1721's running IOS 12.2(4). One router is at the branch connected to two dumb terminals and the other router is at the main connected to a Unix Host. They are connected by a full T-1. My question is how do I config these routers to pass the LAT protocol through. I have looked on Cisco's web site but nothing listed there that really helps. LAT is not even listed as a command if you do a "?" at a prompt!! Any ideas????
