Hi Randy,
Linksys makes a router with built in VPN. You might visit their web site to see more information about it. I use a Linksys router, but it was purchased before Linksys introduced a VPN option with its routers. Also, the following link might be of some help:
http://www.corecom.com/external/vpn/vpnfaq.htmIf all seven connections are coming in over the internet, you would probably need a 16 port router. If only two or three connections are coming in over the internet, and their is a local Lan for the rest that can be uplinked into the router, then a four/eight port router would probably be enough. You will probably need at least a cable/DSL always on connection to get good performance.
