===== Overview =====
The **Port Forwarding** feature is required if you plan to have publicly available servers running on your local network.  For example, you may need use the port forward tool to send voice traffic to a PBX (phone system) running on your local network.

===== Installation =====
If you installed your system as a gateway, this feature was included in the default installation.  If you installed your system as a standalone server, you can still [[Software Modules|install the module]] at any time.

===== Menu =====
You can find this feature in the menu system at the following location:
 
<navigation>Network|Firewall|Port Forwarding</navigation>

===== Configuration =====
If you run servers behind your ClearOS gateway, you can use the **Port Forwarding** page to forward ports to a system on your local network. In the example below, two port forwarding rules are configured:

  * A web server (port 80) is running on the LAN at 192.168.4.10
  * SSH (port 22) is also running on 192.168.4.10. Since port 22 is already used on the gateway, we specify an alternate port (2222). We then configure our SSH client to use port 2222 to connect directly to 192.168.4.10 from the Internet. 

===== Troubleshooting =====
In order for port forwarding to work properly, the target system on your local network **must** have the default gateway set to ClearOS system.
