So here is a problem.  250 users that use one client operating system means 
that you will need (to add?) a person to support (given some form of 
personal Firewall and some automated updating of client software), and 
monitor VPN clients usage full time.  That's a nasty job if you add 
additional operating systems (there will always be one platform that 
doesn't get supported as well as others).  That's multiple bodies as you 
grow to 4000 users.

Would different VPN users belong to different groups and would different 
groups have more or less privileges or access to resources than others.

No mystery.  NAT handling.  Getting through client side Firewalls or filters.

Liberty for All,
