It sounds like the ifconfig usesrc may be what I am looking for, although I can't seem to figure out how I'm supposed to use it...I am also trying to put non-routed traffic (i.e. LAN traffic) out over a specific interface, so I don't know about using route add default to achieve that.
My configuration is something like this: bge0: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 4 inet 192.168.23.200 netmask fffff800 broadcast 192.168.23.255 ether 0:14:4f:b0:b6:ca bge0:1: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 4 inet 192.168.16.2 netmask fffff800 broadcast 192.168.23.255 (where the IP range runs from 192.168.16.0-192.168.23.255) My default route for these interfaces is 192.168.16.1. I want all traffic initiated from the host to go over the 192.168.23.200 (i.e. an interactive SSH, ping, whatever else). If there is a way to do what I want, is there also a way to make it applicable on boot (I currently use /etc/defaultrouter and /etc/hostname.interface to configure the networks)? -- William Yang wy...@tjhsst.edu ----- Original Message ----- From: "Bernd Schemmer" <bernd.schem...@gmx.de> To: "William Yang" <wy...@tjhsst.edu> Cc: sysadmin-discuss@opensolaris.org Sent: Wednesday, February 25, 2009 1:23:32 PM GMT -05:00 US/Canada Eastern Subject: Re: [sysadmin-discuss] outgoing traffic on multihomed hosts William Yang wrote: > > Is there a way to tell Solaris to “prefer” sending outgoing traffic > over certain IPs?

If this is the case you can use either the setsrc option for ifconfig or the setsrc option for the route command. We do use the later on some of our machines because only one IP address of the machines is configured in the firewall. e.g route add default <router_ip> *-setsrc <source_ip> regards Bernd * > > Thanks in advance, > > William Yang > > ------------------------------------------------------------------------ > > _______________________________________________ > sysadmin-discuss mailing list > sysadmin-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss > -- Bernd Schemmer, Frankfurt am Main, Germany http://home.arcor.de/bnsmb/index.html M s temprano que tarde el mundo cambiar .
