Remember that the kernel knows about both networks ... Hmmm. You're right, of course. And even better, it worked when I tried it. ;) Thanks! Now, for the sake of knowledge, let us say that a piece of needed software didn't have an option to bind to a specific interface. Would it be possible to control the outgoing route/interface anyway, by using iptables or some other mechanism external to the software? For example, what if Sendmail didn't have a ClientPortOptions directive (heh, I know, use Postfix, but work with me here)? And remember: This is for something running on the gateway, not forwarding packets received from another machine. :) (No, I don't presently have such a piece of software, but I'd like to know.) Thanks again, either way! -- Ben _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
