Linux VPN

[Warren Togami]

One low cost and effective method is using an SSH tunnel for your VPN
routing.  This document describes SSH VPN with PPP, but it can easily be
adapted for Roadrunner.
http://www.linuxdoc.org/HOWTO/VPN-HOWTO.html

I hope you are only routing TCP/IP or UDP and not SMB/CIFS and/or IPX.
Things become either impossible or incredibly difficult with those protocols
through this type of tunnel.  You can also look at the Linux FreeS/WAN and
GRE support, but I've never tried those.

As for opening a firewall to allow services to a trusted external user, this
is very easy with SSH tunnels.  I suggest using a modern OpenSSH 2.5.2 or
higher SSH server, and the Mindterm client (Java for cross platform
capabilty) for first time SSH users.  Mindterm makes it very easy to
configure terminal settings and tunnels with GUI tools.

OpenSSH 2.5.2x comes standard with Redhat 7.1 and perhaps other recent Linux
distributions.

Mindterm - try their demo, signed applet with full features.  Later you can
download and run the JAR executable locally.
