[pptp-server] Small VPN...

[Seth Northrop]

Hi.  I'm very new to PoPToP, and, didn't find the answer to my question
within the various pieces of documention on the site.  My apologies if
this has been asked before..

I want to build a fairly simplistic VPN.  

Currently a very simplistic view of an architecture looks like:

         --  Mail Server   Intranet
         |-  Web Server    DB
Internet |-  Firewall <--- File Server      
         --  DNS           Internal LAN

Ideally, we want to allow remote users with both static AND/OR dynamic ip
addresses (dialup/DSL/Cable etc.) into the internal network securely so
that we can allow SMTP relaying to only occur from an internal interface /
SMTP server, along with giving users access to our corporate intranet
and/or fileserver(s).

Currently we are doing port forwarding from the firewall and POP
authenticated relay restrictions on the external mail server.  Neither
seem as clean as a VPN solution.  And, absent serving file directories via
apache, we have no good means to provide access to samba shares to remote
users.

Clients are mostly Windows 95/98/2000 with the potential that windows ME
could pop into the picture.  There are also a few linux clients that could
gain access.  

This is not a heavily remotely used network.  I wouldn't expect more than
a couple of people at any given point remotely accessing the
network.. and, of those they will not be pushing a large amount of data.

The question is whether PoPToP is appropriate for this
configuration; particularly as it pertains to routing IP traffic through
the tunnel->internal corporate net from dynamic (unknown) remote IPs.  If
not, what other software/hardware options are there?

Thanks for any input you can share!
