I would like to add a branch office to our vpn. Our HQ has an 1800 for a gateway and another 1800 for VPN. Other remote sites have router/pix combos. Can I configure a single 1760 to terminate the T1 on its T1 DSU/CSU as well as handle VPN duties? A K9 image is installed. I would like to nat the inside to one of our assigned subnets. Any advice would be greatly appreciated!
