Is there an easy way or anyway to establish a 128 bit encrypted tunnel between a handful of centos 5.2 boxes?
I am not familiar with this at all.
If you just need to forward a port or two, ssh is probably fine.
If you need true IP-to-IP connectivity, that's called VPN. There are a few different VPN solutions - probably the easiest complete one is OpenVPN.
Enable the EPEL repository:

Then do "yum install openvpn" Plenty of documentation here:
There are also IPSec-based VPN solutions, but they are more complex.
