May I do a syntactic fault, but I think it has to be like :
$IPTABLES -A FORWARD -i $IF_INT -o $IF_EXT -p tcp -s potsdamerplatz -d IPINTERN --dport FF -j ACCEPT
Isn't $IF_INT the interface for incoming and $IF_EXT the interface for outgoing traffic? If it is, you might try $IPTABLES -A FORWARD -i $IF_EXT -o $IF_INT -p tcp -s potsdamerplatz \ -d IPINTERN --dport FF -j ACCEPT
I think U did -> -d $IPINTERN instead of -d IPINTERN
Right. Copy and paste - my fault :-( So, the rule reads $IPTABLES -A FORWARD -i $IF_EXT -o $IF_INT -p tcp -s $potsdamerplatz \ -d $IPINTERN --dport $FF -j ACCEPT
and what you will do with --dport FF
Take a look at the mail from T-Systems.Ertl@daimlerchrysler.com: he did not want to tell us which port he will forward. So I took FF, too (now as a variable name :-) You didn't mention above, but what the hell is potsdamerplatz? ;-) Martin -- martin.peikert@discon.de Discon GmbH Internet Solutions Wrangelstrasse 100 http://www.discon.de/ 10997 Berlin, Germany
