In your example you'd do: # route delete 192.168.100.254 Of course you have to take care of the routing for yourself. Alternatively (assumeing you are on RELENG_5) you can try to apply the=20 following patch: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/netinet/in.c.diff?r1=3D1.7= 7&r2=3D1.80 to src/sys/netinet/in.c which should fix the problem altogether. Please tel= l=20 me if you have troubles with it as I am going to MFC this shortly. =2D-=20 /"\ Best regards, | mlaier@freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mlaier@EFnet / \ ASCII Ribbon Campaign | Against HTML Mail and News --nextPart1986405.t61413SSZ0 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQBBsLbYXyyEoT62BG0RAtWgAJ9YZfZKX528uWh2xaU4kmh7Y1yoHACeLviw I3bjkOLTIPK5mXn1KkhdhSk= =LFMA -----END PGP SIGNATURE----- --nextPart1986405.t61413SSZ0--
