I have a Cisco 1811 from one of our offices that has been shut down. I would like to now use this router at a new site. The old site used DHCP and the new site can use the same address scheme. The tunnel information should be the same. I know that I need to change the wan interface to the new wan address of the new site. What other settings would I need to change to get this working? I am testing it from my home and have been unable to get the tunnel up. I connected my cable modem to FE0 and changed the ip, and it connects okay. The remote sites use our DNS so that wouldn't need to be changed. I plugged into one of the ports and received an IP. Any tips on getting the tunnel up, is there a command I need to run on the router on the other end? Thanks.
