Port Forward
Port forward is used to allow an external user to reach a port on a private IP address (inside a LAN) from
the outside via a NAT-enabled router (VoloAccess).
When a computer on the Internet sends data to the public IP address of the VoloAccess, it needs to know
how to manage the data. Port Forward tells the VoloAccess which computer on the local area network to
send the data to.
To configure Port Forward select LAN followed by Port Forward in the Navigation panel - the Port Forward
page is displayed:
Enter the Server IP address and Server Port(s), select the Protocol from the drop-down list, and
enter the NAT Port(s) then click the Add button.
Example
In this example, port forward is used to allow incoming access to an internal web server.
