Try this. For the primary ed0 interface, use:

	root# ifconfig ed0 inet 10.20.30.1 netmask 255.255.255.0

This gives you the first one (it'll probably be done automatically by
rc.sysconfig and rc.netstart). Obviously substitute your address for
the "10.20.30.1" example :-)

To add the second address, use:

	root# ifconfig ed0 alias 10.20.30.2 netmask 255.255.255.255

If it is on the same class-c as the first address, or:

	root# ifconfig ed0 alias 10.20.40.2 netmask 255.255.255.0

If it is on a different class-c than the primary ed0 address.

Either alias line can be added to the rc.netstart script to be run
automatically. Put if after the "for ifn in ${network_interfaces}"
block (ie. after the "done").
