Action on RH8
My Firewall configuration looks like this:

/*-----------------------*/
echo " Clearing any existing rules and setting default policy.."
$IPTABLES -P INPUT ACCEPT
$IPTABLES -F INPUT
$IPTABLES -P OUTPUT ACCEPT
$IPTABLES -F OUTPUT
$IPTABLES -P FORWARD DROP
$IPTABLES -F FORWARD
$IPTABLES -t nat -F

echo " FWD: Allow all connections OUT and only existing and related ones IN"
$IPTABLES -A FORWARD -i $EXTIF -o $INTIF -m state --state ESTABLISHED,RELATED -j ACCEPT
$IPTABLES -A FORWARD -i $INTIF -o $EXTIF -j ACCEPT
$IPTABLES -A FORWARD -j LOG

echo " Open ports"
$IPTABLES -A INPUT -i $EXTIF -p tcp --dport 4662 -j ACCEPT
$IPTABLES -A OUTPUT -o $EXTIF -p tcp --dport 4662 -j ACCEPT

echo " Enabling SNAT (MASQUERADE) functionality on $EXTIF"
$IPTABLES -t nat -A POSTROUTING -o $EXTIF -s 192.168.0.0/24 -j MASQUERADE
/*-------------------------------------*/

$EXTIF it's my network card, connected to the internet.
But i check eDonkey 4662 port test, it gives me message (if lMule running):
timeout : connection was accepted on ip xxxxxxxxxx
sent hello but no answer was given !??

and Gives me message:
error/resest on ip xxxxxxxxx!
if lMule is not running.

What i'm doing wrong?

Thank you for any ideas...

if you have eDokey, you will probably want to masquerade your port 4662. Because eDonkey can't connect to your computer behind the firewall because you don't have a public ip for it.

I currently know too less about iptables to give you a command. But search on the internet, how to masquerade a specific port.

Try something like this:
where 192.168.0.2 is your computer with eDonkey behind your firewall and eth1 is your connection to the internet

I'm running eDonkey (actualy it's LMule, eMule for Linux) on my Linux server, not on my remote PC, so it has direct connection to internet.

I guess eDonkey or eMule or whatever also needs an udp port open.

Try this:
I hope this works...

I just finished fixing this same problem on my machine. The problem with me, however, was that I am connecting to the internet through a router (Linksys BFSR41).

To fix it, all I needed to do is set up port triggering for ports 4662 and 4672. You can find out how to do it with other routers at:
