82.225.135.85:

If you set TCP port in [[aMule]] to XX and UDP port to YY then you have to set your firewall like this:

''iptables -A INPUT -p tcp --dport XX -j ACCEPT'' 
''iptables -A INPUT -p udp --dport XX+3 -j ACCEPT'' 
''iptables -A INPUT -p udp --dport YY -j ACCEPT'' 

If you want to setup [[aMule]] behing a NAT gateway, you should add these lines to your iptables configuration script, on the gateway :

''EXTIF'' is your external interface

''EMULEPORT=5595'' 
''EMULEUDP=5595'' 
''EMULEUDP2=`expr $EMULEPORT + 3`'' 
''EMULEHOST=10.0.0.2'' 
''iptables -t nat -A PREROUTING -i $EXTIF -p tcp --destination-port $EMULEPORT -j DNAT --to-destination $EMULEHOST:$EMULEPORT'' 
''iptables -t nat -A PREROUTING -i $EXTIF -p udp --destination-port $EMULEUDP -j DNAT --to-destination $EMULEHOST:$EMULEUDP'' 
''iptables -t nat -A PREROUTING -i $EXTIF -p udp --destination-port $EMULEUDP2 -j DNAT --to-destination $EMULEHOST:$EMULEUDP2''
