Subject: [TriLUG] Re: using a Linux box as a pass-through filter
Yep. This can be done. Someone where I work has a linux box set up as a bridge and is running firewall rules on it to protect a Beowolf cluster. The system is normally invisible to the network.

I want to take traffic in on one port, analyze and drop unwanted packets and then push the acceptable traffic out through the other nic.
I want an in-line filter...
I wish everyone on the list a Happy and Safe Holiday season.
