Interface Grouping
The interface group feature 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.
To create a new mapping group:
1. Click the Add button.
2. Enter a unique Group name.
3. Select interfaces from the available interface list and add them to the grouped interface list
using the arrow buttons to create the required mapping of the ports.
4. Click Save/Apply.
After clicking the Apply/Save button, the Interface Grouping Configuration screen
appears.
