GRT-504 4-Wire G.SHDSL.bis Firewall Router User's Manual
For setting Port-Based VLAN, Click Port-Based VLAN, The screem will prompt as following:
Port-Based VLANs are VLANs where the packet forwarding decision is based on the destination
MAC address and its associated port.
When using the port-based VLAN, the port is assigned to a specific VLAN independent of the user
or system attached to the port. This means all users attached to the port should be members in the
same VLAN. The network administrator typically performs the VLAN assignment. The port
configuration is static and cannot be automatically changed to another VLAN without manual
reconfiguration.
As with other VLAN approaches, the packets forwarded using this method do not leak into other
VLAN domains on the network. After a port has been assigned to a VLAN, the port cannot send to
or receive from devices in another VLAN.
The default setting is all ports (LAN1 to LAN4 and WAN1 to WAN8) connected together which
means all ports can communicate with each other. That is, there are no virtual LANs. The option is
the most flexible but the least secure.
