natd -redirect_port

[Dongxiang Liao]

Hey there,

I have been playing with ipfw and natd to setup firewall and port 
remap, but having problem with a seemingly trivial situation.

I want to redirect the incoming traffic to port 995 to port 22 on the 
same machine.  The man page of natd suggest natd -redirect_port should 
do it.  But "natd -redirect_port tcp 22 995" indicate I am missing the 
target address and alias address.  I don't quite understand the 
situation since I have only one machine itself here.

I would appreciate any suggestions.
