I'd like to see DNAT implemented. Today i had to resolve an issue related to
a wrong SMTP gateway settings for a couple visitors. Their setup pointed to
a foreighn SMTP server, which could not be accessed from our ISP. Once the
SMTP server address was replaced with my ISP everything worked.
If i could have Dnat'ed/pointed all outgoing traffic destined for port 25 to
my own SMTP server, i would have saved a lot of work.
