Hello gang.
I am needing a bit of assistance from one of you firewall gurus. I have
been assigned to set up a drawbridge firewall (or something similar) to
protect a specialized server that we can not contractually harden at the
Operating System level. The problem is that I have been unable to get
traffic to pass between the two interfaces in this FreeBSD box that was
set up using the drawbridge kernel.
I have swapped between about 3 or 4 network cards in a low end Pentium
system. (As soon as I can prove that I can protect the system using
bridging technology and appropriate FW software, then hopefully I can
allocate funds to get a more robust system to be the production FW.) I
have 4 3com 3c905b and 3c905's, an SMC Etherpower combo card, and an SMC
10/100 card that I have used in this system. However I have been unable
to get traffic to make it across the bridge. This leads me to believe it
is a configuration under FreeBSD or with the drawbridge that is preventing
this to work.
Additionally, when using 2 3com cards, I get the following error on
console. "xl1: Watchdog timeout." While using the SMCs, I get this
message.... "tx0: device timeout X packets, seems we can continue
normaly"
HELP!@ Anyone ever experience this, or would like to compare notes on the
drawbridge computer of theirs compared to mine. I am at a loss after
doing some edits on things in the rc.conf, checking irqs.....all the
things I would guess about.
Thanks,
