I also have LimeWire running thru an iptables gateway. In my firewall script, I have:

--------------------------------------------------
# Allow Gnutella forwarding
$IPTABLES -A FORWARD -p tcp -i $EXTIF --dport $GNUTELLA_LISTEN_PORT -o $INTIF -j ACCEPT
$IPTABLES -A FORWARD -p udp -i $EXTIF --dport $GNUTELLA_LISTEN_PORT -o $INTIF -j ACCEPT
--------------------------------------------------

The Listen Port is default (6346) both here and in LimeWire.

My main reason for posting is that even though I see monitored incoming search requests that would match files in my library, there have been absolutely no uploads. I disabled "Automatically clear completed uploads" so that I could be sure.

In Connections I see that I am connected as a Leaf node even though I have specified Cable/DSL for my connection type. And, for "Dropped (I/O)", I have what seems to me to be high percentages, ie.:
87% / 0%
94% / 0%
86% / 0%

The statuses are all "outgoing" and the protocols are all "UltraPeer". The user's manual does not explain what all these terms mean (at least not very well), so I can't determine if this is a problem or not.

My firewall logs do not indicate any dropped packets from any of the hosts in my Connections list nor in my Search/Download list. I get a lot of "Could not download; Awaiting more sources ..." even after a download has partially completed.

Are there any indications here as to why there have been no uploads? Why can't I share my 100+ files? Or is all this "normal"?

Thanks,
LimeWire Newbie -- and likin' it
