>Release:        FreeBSD 2.2.5-STABLE i386
>Environment:
2.2.5-STABLE using ipfw divert/natd for IP address translation
>Description:

It seems that 2.2.5-STABLE has an old version of natd which does
not honor the -port flag correctly. What happens is tat natd chooses
the next free port >1024 which is usually not the one specified by
the ipfw divert line and so NAT fails.

Apparently -CURRENT has a different version (1.8) and the latest
and greatest from ftp://ftp.suutari.iki.fi/pub/natd is version
1.11.

I have successfully built the latter and simply re-installed it
over the -STABLE version.

>How-To-Repeat:

Start natd and run netstat -an to see which port it is listening
on - it will not be on what you have specified!

>Fix:

Bring -STABLE and -CUURENT in sync with the latest version on
ftp://ftp.suutari.iki.fi/pub/natd

This bug is actually mentioned in the list of changes ("service
port is a short, not a long").
