Firewall blocks everything from outside
« on: December 13, 2011, 03:45:54 pm »
Hello,

Im running for a few day's an Zentyal server in my small company and im using it as an gateway to the internet.

The problem im having is that i cant shh or whatever from the outside to the server, inside the network everything works fine.
Which port I try to open it dont work portchecker keeps saying it is closed.

I use Eth2 for the internal network whit DHCP on it and Eth3 on the internet side, when i look at my firewall log i only see Eth2 on the input interface and never eth3 on the input side.

I'm using version 2.2.4
What am i doing wrong?

What am i doing wrong?

Difficult to tell you until you tell us what kind of rule you set at firewall level to authorize incoming flow  ;)

Did you notice FW GUI has different sections for internal and external interface?

I tried almost everything i think, i've done the folowing thing:

Packet filter>Filtering rules from external networks to Zentyal>Add new>ssh

Interface, Original destination, Protocol,    Original destination port, Source, Destination IP, Port          
eth3,        Zentyal,                 TCP/UDP,    Any,                            Any,    192.168.1.160,    Same

And i tried to open almost every port but i cant get it working.

If i try to connect whit shh to the server i get nothing to see at my firewall log. isnt that strange?

Can i chenk on some way if my Eth3 is checked as external WAN? I ckeckt the box on my interface settings.
