port forwarding, OS-X

[R. Scott Granneman]

Create a document named "portforward" with the following 2 lines in it 
(I've numbered the lines to take care of wrapping, so remove the numbers 
when you type it out):

1 /usr/sbin/sysctl -w net.inet.ip.forwarding=1
2 /sbin/ipfw add 102 fwd 127.0.0.1,8080 tcp from any to 123.123.123.123 
80 in

In line 2, replace the 123.123.123.123 with your server's IP address. 
Line 2 also assumes that you told Frontier to run its Web server on port 
8080.

Make the script executable by typing the following:

sudo chmod 744 portforward

Place the script in /Library/StartupItems & reboot to test. Voila!
