Multiple IP's

[David Peterson]

I like that option.  I will give that a try and see if it helps.

Not exactly elegant, but you might be able to use something like this:

 ip route add 198.51.100.0/24 via 192.0.2.1 dev eth0 src 192.0.2.10  ip
route add 203.0.113.1/24  via 192.0.2.1 dev eth0 src 192.0.2.20

If dhcpd lets the kernel choose a source address that should work. It
happens to affect any traffic towards those net that haven't already
selected a source address, not just dhcpd. But it should work.
