Azureus UDP 6881 .... what do I do to open this port?

[PowerMan57two]

I have a Linksys Wireless-G router and McAfee firewall/virus scan and I'm downloading off of Azureus and a message popped up in the lower right hand corner of my screen. It said this:

"If you have a router/firewall, please check that you have port 6881 UDP open. Decentralised tracking requires this."

What does this mean and how do I go about opening this port?

Thank you!!

You need to read your linksys manual. It's probably 192.168.1.1 and type something like admin or password for default access. The option to port forward will be in there somewhere.
