I have a network with 3 segments. 192.168.1.0 192.168.2.0 192.168.3.0. I just installed a cisco 1841 router and the ethernet address is 192.168.1.254. I can telnet into it from segment 1. I need to be able to telnet into it from segment 3. I know there is a command but I am not sure how to enter it.
