Hello,

Seferovic Edvin a =E9crit :
>>$IPTABLES -t nat -A PREROUTING -i $ETH -p tcp --sport=20
>>$UNPRIVPORTS --dport 4444 -d xxx.xxx.xxx.xxx -j DNAT
>> --to-destination 192.168.178.32
>=20
> You need port here !!! --to-destination 192.168.178.32:80

Also, 192.168.178.112 must be the gateway for the return packets so they=20
are properly un-DNATed.
