Title: airport extreme/ port forwarding
Post by: Jhurlbs81 on November 06, 2008, 12:36:27 PM
Hey Guys-

I haven't seeding anything on Bittorrent in a while, and when I tried just recently I have been able to D/L, just not seed.  I've heard Cox is restricting BT traffic, but I have a feeling I might not have my ports forwarded.  Never did anything special in the past, and I always got good speeds both up and down.  So how can I check to see if I'm configured correctly.  I did the NAT/Firewall test thats built into one of the BT clients I tried, and  it said I wasn't configured properly.  Any good (current) resources on port forwarding.   I run Mac OSX 1.4.11 and my wireless router is an airport extreme.

Also looking for a simple 30,000' view of port forwarding.  I understand a comupter has 60,000 or so ports, but when you forward a port what are you actually doing?  Opening it on your router?  Any help would be greatly appreciated.  Gotta get this stuff down before Phish tour!

Thanks
Jesse

I'll look at mine when I get home (memory isn't nearly as good as it used to be). I did a while back; and it was really quite easy.

OK...this is how I did it

- Check to see what the IP of your local machine first (System Preferences> Network> Airport> Advanced> TCP/IP)
- Check to see what port your BT client is running (mine just did the standard 6881-6889)
- Open the Airport Utility
- Click 'Manual Setup'
- Click 'Advanced'
- Click 'Port Mapping'
- Click the '+'
- Under 'Service: Choose a service' select 'Personal File Sharing'
- Under 'TCP Ports' (public & private), enter the ports your BT client is using (for me, that was the range 6881-6889)
- Enter the 'private' IP address for the machine you are using
- Click continue
- You'll be asked to give the service a name
- Click done
- Click 'Update'

It'll take a few seconds for the Extreme to update itself; and then you should be good to go.

You kind of answered your ending questions: the simple answer is yes, you are setting up your router and/or firewall to accept internet traffic through a port to be used by a particular program.  The general consensus is that you should use a port in the upper registers (say, between 40,000 and 60,000) as there seems to be a little more "room to breathe".

There is a great website call PortForward.com that can pretty much walk you through how to set up your computer and most routers for port forwarding.  The page with the guides is here -> http://www.portforward.com/guides.htm (http://www.portforward.com/guides.htm).  Hopefully, Steve J's instructions will go smoothly and you won't need the website.  Quite a few service providers are throttling upload speeds (mine included; bastards!) so I don't think there's much you can do about that.

Personally, the single most important thing that I did when forwarding the ports on my computer was to set up a static IP address and then everything seemed to fall into place, but YMMV.  Good luck.

Cool.  Thanks guys!

The portforward.com website rocks.  Very clear, up-to-date information.  Setting up the static IP and the port forwarding was a breeze with the right instructions. 

I'd +T ya if I could!

Thanks
