IF you are not stuck to IPSec, you might want to take a look at OpenVPN (www.openvpn.org). I found OpenVPN easier to install than FreeSWAN (an IPSEC VPN) and have setup an OpenVPN solution between my German office and our mainoffice in a matter of hours.
I have to second (resoundingly) Thom on this one. FreeSWAN is perhaps the most painful tool I have ever dealt with on a linux system, and I would avoid it if you could. OpenVPN is much more user friendly, though ultimately my company ended up using hardware appliances here (turned out to be cheaper than paying the sysadmin regularly to keep things up).
If you are running Centos 3.x you still have CIPE as a fill-in-the-form option in the redhat-config-network GUI (Click the 'new' button above the devices tab). Unfortunately it is gone in Centos 4.
