Re: Azureus and the TCP port 6881

Hello Gene,

thank you very much for your answer. However, I am a completly ignorant
regarding NAT... after reading your advice, I went to the NAT howto and
I was scared...

iptables is, in fact, an (from the man page) "administration tool for
IPv4 packet filtering and NAT". You suggest to use iptables to set up a
NAT rule, isn't?

my router, I guess, is with my IP provider... I can't do anything in
that machine...

My problem is that I want to open port 6881 (or another one,following
Chris Howie's tip) for Azureus. I have sarge installed in my machine at
home, wired to my Internet Provider trough an ADSL connection. I would
like to be able to open the ports without having to study the gory
details of NAT... sorry, I am not lazy, I don't have the time for it...

With the best regards,

Marcelo
