T1 comes into Adtran.  They wanted to use 5 of these little D-link gateways
to bust out the networks.  Unfortunately, the D-link "routers" are gateway
routers and not usable for public IPs.  So, I'm looking for the next best
alternative since their first choice failed miserably.

Yes, the Adtran is T1 on one side and Ethernet on the other.  I'm not way
way familiar with the Adtran NetVanta 3205 since, with the exception of
Glaxo, EPA and Pharmacia Upjohn, all my customers are small and housed on
one subnet.  Apparently, the Adtran has some kind of security zone feature
used in conjunction with a managed switch.  I'd like to hear from someone
that has made it work.

Bah.  We have Linux.  We have Apache.  We have beer.  We can make it work.
