I'm having a major problem trying to forward packets from either a workstation of the LAn to the Internet.
I want to be sure I'm doing this correctly.
I set a forward rule:
$IPT -A FORWARD -i $INT_IFACE -o eth1 -p tcp --dport 1262 -j ACCEPT
Then I set a PREROUTING rule
$IPT -A PREROUTING -i $EXT_IFACE -p tcp --dport 1262 -j DNAT --to-destination 192.168.xxx.xxx
All I can see using tethereal on the network is SYN packets.
Any idea what I'm doing wrong?
Thanks
