In response to a recent request for Linux packet filters, have you
considered NetBSD/FreeBSD? There are plenty of packet filtering packages
available for these systems.
I have developed a packet filter for NetBSD that I am willing to let
people beta-test. If anyone wants more info, let me know.
On the same topic, I recently saw a recall notice for Cisco routers that
indicates a vulnerability that permits packets to bypass the filtering.
I wonder: is my filter vulnerable? Although the hole was discussed
"in the appropriate places", I was not privy to those discussions. Can
someone point out the hole, or offer to demonstrate it by putting a
packet past a test firewall?
