Port Mapping

Port mapping is a feature that allows you to open ports to allow certain Internet applications on the WAN side to pass
through the firewall and enter your LAN. To use this feature, mapping groups should be created.
Click on the Add button to create a mapping
group.
If you need to remove an entry, select the
checkbox in the remove column next to the
