Port Forwarding

Hi,

i would like to forward ports to access a tomcat-webserver running on a linux-machine that is connected to the Conduit which got an LTE-connection to the internet. The setup looks like this:

some device with internetconnection (used to connect to: <public-ip-of-conduit>:8080/index.html)
|
|
|
Internet
|
| (connected via LTE)
|
Conduit (v1.1.2)
|
| (connected via LAN)
|
linux-machine (tomcat-webserver running on 192.168.2.213:8080)

I tried to forward port 80 and 8080 using the conduit’s web-interface (Firewall>Settings>Port Forwarding) specifying the ports and the destination-ip “192.168.2.213″.

Unfortunately it’s not working and i can’t access my webservers-page (<public-ip-of-conduit>:8080/index.html). The page http://www.yougetsignal.com/tools/open-ports/ shows me, that the ports are closed.

What am i doing wrong?

Thanks in advance

Regards
Daniel
