I have a BEFSR11 router that I've had for four years. In the past, I've had a Cisco VPN client work without problem. OLD PROBLEM: Recently, I moved to a different company with a Nortel 4.x VPN client. I found that I couldn't get it to work until I upgraded my firmware -- and then it worked without issue. NEW PROBLEM: The company upgraded me to the 5.x VPN client. Now I can never get it to work right. When I unplug from the router, and connect to my DSL modem directly with the built-in Windows PPPoE client, everything works perfectly. AND THEN: when I reconnect from behind the router, everything works fine! (Is this some kind of key negotiation that gets blocked due to needed port(s) not being allowed out???) As I guessed, a few weeks went by and once again, it doesn't work. (sigh) What do I need to do to the router to get this working with the Nortel VPN client again? My network is a single Linksys router behind a DSL modem, a 24-port switch from which hangs a wireless access point (separate network entirely, using the same gateway), a VoIP adapter and all of my wired devices (desktops, network printer, etc).
