When VPN problems arise with specific applications, always look at MTU as a possible culprit.
Thanks for the suggestion. I should say that I am running OpenVPN on my system with no problem at all. Also the AT&T VPN apears to be running fine; it is just the sametime program running over VPN which is not working properly.
Incidentally, what would you suggest as a possible MTU value? And what is the simplest way to change the MTU on a CentOS server?

I have only run Windows through the home routers. If I recall correctly (bad memory sometimes), I had to open port 500 (isakmp) for IPSEC to work.
