I am trying to set up a lab environment using a Cisco Router. It could be any of the following, 1720, 1721 or 2621. I have run into the same problem with all three. I have started with a clean router by erasing the NVRAM so there are no extraneous commands floating around.
Router with two Ethernet ports:
192.168.1.1 255.255.255.0
192.168.2.1 255.255.255.0
Two Computers.
192.168.1.2 255.255.255.0 Gateway 192.168.1.1
192.168.2.2 255.255.255.0 Gateway 192.168.2.1
I am trying to ping from one computer to another. The ping never makes it. Ether computer can ping both ports on the router with no problem. Ether gateway can ping the computer connected to it with no problem. I can get the computers to talk if I use NAT. This is not what I want. I just want the router to route packets between the 192.168.1.0 and 192.168.2.0 networks. I must be missing something obvious.
Thanks
Dan
