Hi folks,

I'm running FreeBSD 3.3 RELEASE.  I have a NIC (ed0) with two
addresses (or aliases). I need to specify the first alias to natd,
through its '-n interface' argument. I don't know the IP address
assigned to this alias because it's assigned through DHCP, so I can't
use natd's '-a address' argument instead. How do I specify the first
alias of ed0?

(I do, however, know the address assigned to the second alias -- it
is always 192.168.0.254 and I was looking at the -reverse argument.
Would it work correctly if I specified '-a 192.168.0.254 -reverse'?)

I'm asking because this firewall ran Linux with so-called IP-
Masquerading with two addresses on one NIC, and this configuration
worked for many months until Linux died mysteriously.  The first
alias was specified to ipchains as eth0:0.  Under FreeBSD, is it
possible to specify ed0:0 or something like that?

Please help or point me in the right direction.  I've already read
the man pages of natd, ifconfig and rc.conf, and about 200 messages
on the mailing list archives.  Thanks in advance.

Kindest regards,
Nathaniel G H
