P12 to access router
The Vigor router supports up to 50 VLANs. Within the grid of VLANs (vertical columns) and LAN
interfaces (horizontal rows), all hosts within the same VLAN (horizontal row) are visible to
one another.
Inter-LAN Routing allows different LAN subnets to be interconnected or isolated. It is only
available when the VLAN functionality is enabled. In the Inter-LAN Routing matrix, a selected
checkbox means that the 2 intersecting LANs can communicate with each other.

The router will add specific VLAN number to all packets on
the LAN while sending them out.

packets sending by LAN.

increasing order of priority.
Select to allow untagged hosts connected to LAN port P12 to
