How do I forward port 3689 to a different port?

I did it with port 80, but I can't find port 3689 in terminal

Firewall forwarding
You can use ipfw to block port 3689, and forward another port to port 3689. Others attempting to connect would need to use the other port, but iTunes would still listen on the default port (3689).
sudo ipfw add 2000 deny tcp from any to any 3689 in
sudo ipfw add 2000 fwd 127.0.0.1,3689 tcp from any to any 36890 in
(2000 is an arbitrary rule number; use the next available rule number.)

To remove the rule:
sudo ipfw delete 2000

It didn't work - by the way, my Firewall is OFF

It works here:

Code:
gatorparrots% sudo ipfw add 2034 deny tcp from any to any 3689 in
02034 deny tcp from any to any 3689 in
gatorparrots% sudo ipfw add 2034 fwd 127.0.0.1,3689 tcp from any to any 36890 in
02034 fwd 127.0.0.1,3689 tcp from any to any 36890 in

Did you do a sudo ipfw list to see the next available rule number?

Ok I did it and a friend of mine managed to connect to my itunes. However he cannot play any song. Here is the list of rules now active, in Terminal. I wonder if there is a conflict among rules.

02000 allow ip from any to any via lo*
02010 deny ip from 127.0.0.0/8 to any in
02020 deny ip from any to 127.0.0.0/8 in
02030 deny ip from 224.0.0.0/3 to any in
02040 deny tcp from any to 224.0.0.0/3 in
02050 allow tcp from any to any out
02060 allow tcp from any to any established
02070 allow tcp from any to any 80 in
