azureus: NAT error

(eth_card) is network interface (e.g. 'eth0')
(port) is tcp port you want to use for setup in azureus

If Azureus is running on the same machine that iptables is active on, use this command instead:

  /sbin/iptables -I INPUT 1 -i (eth_card) -p tcp --tcp-flags SYN,RST,ACK SYN --dport (port) -m state --state NEW -j ACCEPT
/sbin/iptables -I INPUT 1 -i (eth_card) -p udp --dport (port) -m state --state NEW -j ACCEPT 



Then you will see the speed change a big multiplication factor.
