Unable to forward port

New postby marceloudi » Sat Jan 24, 2015 3:58 am

Hi!

I'm using Artica v.1.9 community edition.

I need to forward (dnat) an external port to an internal server.

I have 2 interfaces:

- eth0: internet link: Firewall active
- eth2: intranet: Firewall inactive

I just configured on eth0 an Forward rule, but it's not working. (image attached)

The rules created by Artica (at /bin/artica-firewall.sh) are:

/sbin/iptables -A FORWARD -i eth0 -p tcp --dport 3307 -m comment --comment "ArticaFireWall" -j ACCEPT || true
/sbin/iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 3307 -m comment --comment "ArticaFireWall" -j DNAT --to-destination 192.168.0.1:3306 || true
/sbin/iptables -A POSTROUTING -t -i eth0 -p tcp --dport 3307 -m comment --comment "ArticaFireWall" -j MASQUERADE || true

I receive the error: Bad argument `eth0', but I can not alter this created rules...

How can I forward an external port to an internal server??

I just stucked from 2 days!

Please help!
