Hi im setting up a connection between one of our offices back to our main office. Now on the remote side im going to be using a cisco 1601 with a cable modem connection with a static ip. At our main office we have a 2601 router which has a T1 connection to the net. Now on the 1601 can i use a T1 interface card for the cable modem connection? also i will be using this for vpn traffic so i know i have to create a tunnel on both routers but is there any thing else i would have to do? Also if anybody has any advice on this type of setup i welcome ideas and such.
