I did two things and problem is disappears for now (I live without changing default route longer then ever now) 1. I disabled snmpd 2. I installed and started to use "bird" routing daemon. With configuration like this. protocol kernel world { persist; # Don't remove routes on bird shutdown scan time 20; # Scan kernel routing table every 20 seconds import none; # Default is import all export filter { if (net =3D 0.0.0.0/0) then { if proto =3D "def" then accept; } reject; }; } protocol device { } protocol static def { preference 1000; # Default preference of routes route 0.0.0.0/0 via x.x.x.x; # My default gateway } I don`t know is it helps or not at all, but you should try if you in desperate situation as you told. 2013/1/10 Radek Krej=C4=8Da > The following reply was made to PR kern/174749; it has been noted by GNAT= S. > > From: =3D?iso-8859-2?Q?Radek_Krej=3DE8a?=3D > To: 'Krzysztof Barcikowski' , > "bug-followup@FreeBSD.org" > Cc: > Subject: RE: kern/174749: Unexpected change of default route > Date: Thu, 10 Jan 2013 12:29:15 +0100 > > Hi, thank you for response, because problem is very bad for us, because > our=3D > customers leave us.
