Re: IP Routing Question
Well, the solution ended up just setting up the rule for the subnet, not the host... route add aaa.bbb.ccc.200/29 aaa.bbb.ccc.200 -interface Had to move some IP addresses, but at least the traffic is going to the right ethernet controller now.

IP Routing Question
I'm trying to set up the routing table to force requests to certain IP addresses to use a particular ethernet card. I've used the route command in a number of ways, but still can't come up with how to force to use em1 instead of em0, with the right gateway. em0 is aaa.bbb.ccc.207 em1 is aaa.bbb.ccc.200 Both have netmask of 255.255.255.0 em0 goes to the main port, gateway aaa.bbb.ccc.195. em1 goes to a switch, which is aaa.bbb.ccc.196, the gateway to other ip's on the switch. What I want to end up with is: aaa.bbb.ccc.196link#2em1 aaa.bbb.ccc.209link#2em1 I've tried lots of combinations, using the -ifp flag to force em1, but the only way I can get the gateway to say link#2 is to ping the ip first, whereas it gets put in the table even though it's not found, and then doing a route change. I need some way to put this in rc.local so that it's set up when booted. Any ideas? Let me know if more info is needed.

Re: IP Routing Question
Hi, You can try using ipf filter to impose source-policy routing: cat ipf.example pass in quick on em1 to em1:192.168.1.2 from 10.1.0.0/16 to a.b.c.d/32 ^d ipf -f ipf.example This way you will re-route all packets coming from source 10.1/16 to destination a.b.c.d to go to address 192.168.1.2 not to a.b.c.d Note that you have to rebuild your kernel in order to have options IPFILTER enabled.

RE: IP Routing Question
You are not correct in that last statement. ipfilter does not have to be compiled into kernel to work. You should read the handbook ipfilter firewall section where it clearly states that is not necessary and tells you how to do it. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Goran Gajic Sent: Tuesday, February 14, 2006 9:44 AM To: [EMAIL PROTECTED] Cc: freebsd-questions@freebsd.org Subject: Re: IP Routing Question Hi, You can try using ipf filter to impose source-policy routing: cat ipf.example pass in quick on em1 to em1:192.168.1.2 from 10.1.0.0/16 to a.b.c.d/32 ^d ipf -f ipf.example This way you will re-route all packets coming from source 10.1/16 to destination a.b.c.d to go to address 192.168.1.2 not to a.b.c.d Note that you have to rebuild your kernel in order to have options IPFILTER enabled.
