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.
IGMP
Transmission of identical content, such as multimedia, from a
