Hello all, I have a firewall running iptables and connected to the internet with ISDN and it has static ip. Behind the firewall i have a samba server which also has ssh server. I want people from internet to connect with ssh and use the sftp-server in order to put/get files to that server. So i said i will use these rules $IPT -t nat -A PREROUTING -i $EXT_IFACE -p tcp -s ! $LAN_IP_RANGE --dport 2222 -j DNAT --to-destination $SSH_SERVER $IPT -A internet-lan -p tcp -d $SSH_SERVER --dport 2222 -m state --state NEW,ESTABLISHED -j ACCEPT $IPT -A lan-internet -p tcp -s $SSH_SERVER --sport 2222 -m state --state ESTABLISHED -j ACCEPT I did n't try it so i would like to know if is it possible this scenario to work?
