FreeBSD and two different networks

How about dhclient enter-hooks:

‎http://www.macfreek.nl/memory/DHCP_Client_Script_Examples

"If you want to have more control, e.g. only set the default route for em0, but not for other interface, add the following lines to /etc/dhclient-enter-hooks:
# Do not set default route on any interface except em0
if [ "$interface" != "em0" ]
then
    unset new_routers
fi
"

There's also "supersede" in dhclient.conf to overwrite what dhcp provides and set to something you want (think overwrite) ‎
