iptables port forwarding for emule

Suppose you wanna have HighID and open KAD network connection for eMule on a computer in a LAN, and the gateway is running iptables. Just add the rules below to your existing iptables rules and you are done.

# this example is based on the assumption that 
# eth0 is WAN interface and eth1 is LAN interface,
# is the ip address of a computer in LAN,
# 4262 is the tcp port for ed2k network,
# 4272 is the udp port for kad network.

-A PREROUTING -i eth0 -p tcp -m tcp --dport 4262 -j DNAT --to-destination
-A PREROUTING -i eth0 -p udp -m udp --dport 4272 -j DNAT --to-destination

-A FORWARD -d -i eth0 -o eth1 -p tcp --dport 4262 -j ACCEPT
-A FORWARD -d -i eth0 -o eth1 -p udp --dport 4272 -j ACCEPT
