[MLUG] Need advice from security experts

[Matt Krause <EMAIL:PROTECTED>]

I have started building a firewall from an Xserve G4 running Yellowdog.  
We would also like this to be a VPN box as well. Our main goal is to 
allow multiple home users access to their desktop machines at work using 
Timbuktu.  Is this even possible?  I am a little fuzzy on whether or not 
iptables will allow me to forward the timbuktu ports to different 
machines depending on where the traffic is coming from.  Is this 
something a VPN would do along with secure traffic?  i.e.  The user logs 
on to the VPN and then the firewall can determine which machine to 
forward the ports based on the username?

I am looking at different VPN servers right now, but Super FreeS/WAN 
looks like it might work since the super version has the NAT Traversal 
patch already included.  Our entire company is NAT'ed behing a firewall.

Are there any other better ways to do what I need to do.

Thanks a bunch.
