My corporate office runs on a PIX 515. For many months I have been running my Cisco VPN Client version 3.5 to my corporate office, from home, on a DSL router, successfully. Yesterday, I installed a PIX 501 on my home DSL line and now I'm no longer able to establish my VPN connections. Anyone have any ideas? It was working fine without the PIX, so I assume there is some configuration in the PIX501 that I have overlooked.
