I'm not sure about the PCI card.  I can try and get some info on that.

Yes, this is called IP Masquerading or Network Address Translation
(NAT).  We talked about it at our Monday meeting actually :-)

There is an IP-Masquerade mini-HOWTO that is quite helpful and would
be a good starting point.

As for mail, if you want multiple accounts to be visible to the
outside, you'd need a special arrangement with your ISP.  I know that
SouthWind offers UUCP, Virtual domain e-mail (all e-mail to a
particular domain goes to a single POP box on the server), and SMTP
store-and-forward.  UUCP is particularly well-suited for Linux, and is 
cheap.  The downside is that these solutions generally require you
register a top-level domain with the InterNIC, which is $70 for the
first two years.  ($35/yr)

If all you want is to be able to send e-mail between internal
accounts, that's easy and we can discuss that setup in just a few
messages here.
