I have real external IP addresses for all voip phones and for
asterisk.  The phones are outside the firewall and asterisk is running
on the same box that does the firewalling and NAT-ing for a bunch of
computers that don't need real addresses.

I didn't even try to get voip working with NAT.  Sorry for not
mentioning it sooner.  I didn't realize you were trying to NAT things.
