Hi, Does anybody have a hint on what could cause this ? Feb 22 17:49:13 madrid /kernel: ipfw: 20150 Reset TCP 209.155.82.18 146.164.53.65 in via ed0 Fragment = 182 Feb 22 17:49:21 madrid last message repeated 5 times 209.155.82.18 is wcarchive.cdrom.com, 20150 is my ipfw rule that deny every TCP incoming packet for a disallowed (not allowed in a previous rule) port. The problem is why is it getting here fragmented. IIRC, FreeBSD's TCP has path MTU discovery, right ? On my side, every hop is an ethernet or fddi, until the international link, which has a 1500 byte mtu. Jonny -- Joao Carlos Mendes Luis M.Sc.
