Hello List!

I made this rule for portforwarding:

	(1)	iptables -t nat -I PREROUTING -i $ext_if -p tcp --dport
$port -j DNAT --to $local_ip:$local_port

But a client connection from outside on that specified service port couldn't
be established. iptables -vL shows me not a single packet has hit that rule
and therefore didn't pass through the FORWARD chain which of course has to
be set to ACCEPT by default or in my case when DROP is default another rule

	(2)	iptables -I FORWARD -i $ext_if -o $int_if -p tcp --dport
$port -j ACCEPT

is needed.

ip_forward is enabled. 

Anyone having an advice?
