Currently modifying a port for one of the rules on the NAT page does not
update the related rule that was "auto-added" to the Rules list. I find
myself constantly having to modify both.
The first time this happened to me, I was rather stumped trying to figure
out what was wrong with the firewall and why my port was no longer working
until I realized that the other rule needed updating as well. This is
probably obvious to most of you, but this is probably a good thing to keep
newbies from getting confused.
