There is no "route monitor" output when it happens. "fstat | grep route" periodically gives just ntpd and bsnmpd. I turned it off, no change. I tried to turn TSO on all em interfaces - no change. Three routers with similar setup and problem of changing default gateway or static routes: - 9.0-RELEASE-p1 FreeBSD (amd64) - IPFW & dumynet for shaping - PF for NAT and filtering I do not use MPD. However I do use PPPoE in my network, terminated at Mikrotik Routerboard and then routed to FBSD. Sorry for my poor english. Best regards! Krzysiek
