VPNC error, tunneling through TCP not supported
I am trying to setup VPNC on Ubuntu 8.04 to work on a Cisco VPN that is setup at my office. I installed VPNC and then imported the pcf file and get this message:
The VPN settings file 'ComanyName_VPN.pcf' specifies that VPN traffic should be tunneled through TCP which is currently not supported in the vpnc software.
The connection can still be created, with TCP tunneling disabled, however it may not work as expected.
As such, the VPN does not connect at all. Anyone have any thoughts, will it just plain not work on VPNC? So far I am having no luck installing Cisco's VPN client so I thought that I would try VPNC but that is not working either.
well it's excatly as it says, no ipsec over tcp. it does support over udp and also Nat-t so just change it to use those instead, although nat-t is implicit in there being a different between the peer ip you present to the remote site in terms if ip source and your reported own source address, so should attempt this automatically if it will be acceptable.
