I want to setup my main site to connect to all child site slocated on the internet through VPN tunnels. I have about 60 child sites, and thier circuit speed range from 128K to a Full T-1. My main site conection to the internet in a T-1. I want setup a 3DES IPSEC VPN Tunnel from my main site to all child sites, like a star toplogy. What router is recommnded for such setup that will handle all the tunnels? 3600? 3700? 7XXX? All child sites have 2621 routers, which shouldn't be a problem running one VPN tunel on. Is there a formula out there to calcultae the number of tunels on each router, to see the capacity on the main router site? Should I get a separate VPN card for the router?
plz advice and thanks in advnace
