I don't think you've missed anything. In /etc/rc.conf
you can add something like:
ifconfig_rl0="inet 192.168.17.1 netmask 0xffffff00"
ifconfig_lo0_alias0="inet 172.17.0.1 netmask 0xffffffff"
...to give you the general idea. It's enough to bring
the NICs up and running, but then consider DNS
and other issues that provide for a networking
