I guess I'm confused as to how the router and the DSL modem are
connected to your network--If the DSL modem is doing NAT for you, and so
is the router (rather odd, but should work), then you may have things
set correctly, but then the router is using two interfaces, perhaps
192.168.0.X connected to the DSL modem, and 192.168.1.1 connected to the
linux machines--if so, you probably want to have the DSL modem forward
to 192.168.0.X (whatever the router's address is on that subnet)--the
DSL modem likely doesn't know about the 192.168.1.X network.
My network configuration is the "odd" one described above. I changed
the DSL modem port forwarding IP to 192.168.0.3, the address assigned to
the router by its DHCP. Now everything works fine. Thanks for the
help!
I believe that the recommendation is now to _avoid_ using ports 6881 to 6999.
I believe that azureus will only use one
port (for both TCP & UDP), so there is no need to blow big holes in your
firewall. Various ISPs are apparently either rate-limiting (most
likely) or blocking (unlikely??) the old typical bittorrent ports, so
you may just have better luck if you switch to a different
higher-numbered port--make your router and any FC5 iptables firewalling
rules let in the packets for the port that you choose.
port 6973 works fine -- maybe my ISP doesn't see bittorrent as a
problem... yet anyway :}
