Basically, some piece of ipfw or other kernel code unknowingly stomped on the two bytes of RAM which contained the rule number. The rule should have contained 65535 (as a short), or 0xFFFF, but instead had 0x0000. Another mystery is why a flush would not have eliminated this rule. The flush code removes everything but rule #65535. Do you still have the problem SNAP kernel? If it's configured with 2940 or 53c810 support I'd like to give it a try here. Alex
