Cable Modem Config on Cisco 1601

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.

Actually, I'm not 100% positive the 1600 supports trunking/VLAN's.  In the end, you are better off using a two ethernet interface router.

You can't use a T1 interface for the cable modem as the handoff from the cable modem is Ethernet.  You will need two ethernet interfaces on the 1601 whether physically or virtually via 802.1Q trunking.

At the moment the 1601 has only 1 ethernet port eth0 so do they make another add in card for ethernet? or what do you suggest?

I don't believe there is an ethernet add-on for the 1601.  Do you have an 802.1Q trunking capable switch at the site?  If so, you could create a virtual ethernet interface on the 1601 for the cable modem connection but that is the best you can do without using a two ethernet interface router.  You need to be running an IP PLUS IOS image on the 1600 to do trunking.  Can you post a "show version" from the router?

Ok well i was hopeing that it would work, but your right! maybe you can answer this then could i use lets say a linksys wrt54gl with ddwrt on it for my router and get the same results?

That Linksys would work for Internet access but I don't believe it has VPN capabilities.  You would need to invest in an RV0xx from Linksys in order to build a site-to-site VPN.
