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.
