socket / bind - specific address

[Edwin Groothuis]

The situation is as follows:

We have a couple of FreeBSD routers, with RFC1918 addresses on the
ethernets and a public address on the loopback. This works fine for
connecting to the routers, but is problematic for locally originated
outgoing traffic (think NTP, think syslog): it takes the IP address
of the outgoing interface, which is the RFC1918 address.

Is there a way (sysctl, kernel option) to define which IP address
is used for locally originated outgoing traffic?
