Hi

Everyone is recommending port 6881, great because that's what Bit-Torrent
(uses) but this port is blocked by many companies to limit and restrict this
kind of traffic.

Lots of people recommending that you choose some vast and strange port to
get to the tracker, for example I use 44791, it's a random number I choose,
and I nearly (provided there's seeders) have a smiley face. I recommend
Azureus over any other BT client, though it does chew the memory being a
Java application.

The following website is good for instructions for lots of modems/routers to
get port-forwarding working successfully! I see they have Motorola but not
your model! Doh!

Thanks, David Moyle

Ok, I will assume you know nothing about IP networking.

Basically each type of traffic is divided up into ports. DNS, for  
example, is port 53. HTTP is port 80, etc. Bit Torrent is usually  
port 6881

Port forwarding works by listening on a specific port number for any  
traffic and if a packet comes into that port it sends it to the  
specified address.

<internet> ---> (packet on port 6881) ---> <cable modem> ---> (packet  
on port 6881) ---> internal machine

So, you need to log into your cable modem via the web interface and  
look for a section called "Port Forwarding"...this might be under a  
section called "NAT". In this section you will say anything coming  
into this router on the external IP on port 6881, send it to the  
internal IP address of the PowerBook on port 6881...you should have  
an option for this to be TCP or UDP or both...so select both.

Sorry I can't be any more specific as each modem differs in the way  
they are configured...but it isn't very hard to figure out.

Cheers,

Adam.
