    i would like to request some imput about the best design
    for a firewall given my limited resources and needs.

    i work at a unviversity with all the security implications
    that go with it.

    Equipment:

     firewall: pentium II 64 MB ram, 1.2 GB, 2 NICs. RedHat, 6.2.

     production machine: Pentium II 256 MB ram, two HD (one Linux 13 GB
     one 4GB Windows.

     a laptop used both in field and office for diverse projects

     4 place hub.

    Need a mail server, probably PostFix - unless i hear otherwise.

    The best firewall design seems to be a DMZ, but i don't have enough
    machines.

    Should the mailserver go on the firewall or on the production
    machine where i will be playing with databases, docbook and
    doing serious writing and minor graphics? And, of course making
    serious mistakes.

    Is PMfirewall ok, or is it best to roll your own?

    Thank you.
