Mac os x ipfw forward from ip:port to ip:port I want when on my local machine redirect from 192.168.64.88 port 80 to localhost port 9790. How can I do it with ipfw rule?
I found the solution:

sudo ifconfig lo0 192.168.64.88 alias
sudo ipfw add fwd 127.0.0.1,9790 tcp from me to 192.168.64.88 dst-port 80


After a restart you have to run this commands again.
