I am trying to get a VPN client to connect via TCP to a router. I currently have the router set up (and working) using a UDP-VPN. Unfortunately one of the sites I visit wont allow VPN traffic out of their firewall. I have looked all over the Cisco site and am unable to find info on configuring IOS to accept TCP-VPN connections. I would like to change the port to tcp 80, so my VPN traffic just looks like standard internet browsing to my clients firewall. Any links/pointer would be greatly appreciated.
