6.9 Port Mapping
Port Mapping supports multiple ports to PVC and bridging groups. Each group will
perform as an independent network. To support this feature, you must create
mapping groups with appropriate LAN and WAN interfaces using the Add button.
The Remove button will remove the grouping and add the ungrouped interfaces to
the Default group. Only the default group has IP interface.
To add a port mapping group, simply click the Add button.
To create a group from the list, first enter the group name and then select from the
available interfaces on the list.
