Letters: Firewall Flap

Adrian Peters replies: Although I can't speak for your tests, I can assure you that we subjected all the firewalls in our review to very high stress. For every test we conducted, each firewall ran the same gauntlet at least three times. We left it to the vendors to provide the appropriate hardware and configure the firewalls.

We pushed throughput and state tables to the limit, with firewall rule sets averaging 100 rules each. A simpler network architecture with fewer clients would have yielded different results.
