I had previously added the postrouting rule to my /etc/sysconfig/iptables: -A POSTROUTING -m policy --pol ipsec --dir out -j ACCEPT this did not make a difference, I could not ping anything over the vpn link. I think I'm going to have to just hang this up and look for an alternative VPN solution, like the openvpn binaries included with CentOS. Unfortunately strongswan is proving too difficult to get working and I do not have the necessary technical background to figure out why its not working, and the various online guides/wiki assume a degree of technical knowledge I just do not have to fully understand. Thank you for all your help,
