Hello. I am very new to iptbales. I have setup my FW and it is working fine. I have an FTP server on my LAN. I can see connection attempts from the outside over FTP. I'm sure it has to do something with the FORWARDING or NAT If somebody could pleace help me out. Thanks in advance

External IP of FW: Cable Link (24.157.3.200)
INternal IP of FW: 192.168.10.2
IP of FTP server: 192.168.10.15

try...

iptables -t nat -A PREROUTING -p tcp --dport 20 -i eth0 -j DNAT --to 192.168.10.15:20
iptables -t nat -A PREROUTING -p tcp --dport 21 -i eth0 -j DNAT --to 192.168.10.15:21

might work..
