linux firewall for NT domain

[Joel Dudley]

We have a linux firewall guarding our NT domain here.  You really don't need
to worry about NT and linux integration.  In the situation you describe,
that is waht you really don't want.  Just set up a multihomed IPCHAINS,
IPMasq firewall and have the machines access the private NIC as the default
gateway.  Make sure packet forwarding is endabled.  A PII300 would be
overkill for what you want to do.  Our firewall is a P200 with 32 megs of
RAM and it runs great.  In fact, our machine is overkill.  Feel free to mail
me off the list with questions.
