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: http://fedoraproject.org/wiki/EPEL/FAQ#howtouse Then do "yum install openvpn" Plenty of documentation here: http://openvpn.net/ There are also IPSec-based VPN solutions, but they are more complex. -- Florin Andrei http://florin.myip.org/
