Hi, I am using FreeBSD 7.3 STABLE-201004. IPFW + In kernel NAT and if_vlan used mostly. System has 3 em interfaces. Scenario is classical, LAN DMZ WAN. Sometimes default router changes unexpectedly. I inspected logs if someone logged in or changed route. I found nothing. This problem repeats at least 1 times per day. I wrote a shell script which monitors the default router. I saw that sometimes netstat -rn shows that default router is changed as 10.3.1.64 or 10.5.3.189 etc. which are client IP addresses but routing still routes to right router 212.X.Y.Z . After a while, routing really fails. This problem occurs at multiple routing table supported freebsd versions. I dont use this feature. Regards, Ozkan KIRIK Mersin University @ Turkey
