GTK-Gnutella firewall problems: could it be portmap?

[res_nullius]

This seems to be a fairly common problem
so I'll ask here even though I may figure it out anyway.

Running GTK-Gnutella 0.95
on a vanilla Debian Sarge setup.

I'm sure I've set port forwarding correctly on my ADSL router,
checked my ISP doesn't block the ports I'm trying etc.
because I've run Gnucleus successfully from my doze side.

I've tried reaching the port from the net.

So it must be something local.
As I understand it, two things could be causing the blockage:
the local firewall (which I believe is called ipchains),
or the portmapper.

Am I on the right track?
Could anyone link me to a howto
which would teach me how to open
a one port hole for gnutella?


Advice would be much appreciated.
My 7 year old son wants better search results
and I'd hate to disillusion him as to my computing ability!


Thanks

Running GTK-Gnutella 0.95

Try to keep gtk-gnutella more up to date. The older the version, the worse the results will be. As the current version is allready 0.95.4

I've tried reaching the port from the net.

And what happened? Could you reach it. What port did you open?

or the portmapper.

GTK-Gnutella does not use the portmapper. So you can ignore that one. That leaves your firewall (could be ipchains, can also be iptables)
