VLANs
VLAN’s allow users to specify which ports are “bridged” – that is, where broadcast
traffic will be shared. This allows users to create separate subnets on each LAN
port (or group of LAN ports). Note that although there are 15 VLAN’s available,
there are only 5 ports (4 x LAN, 1 x WAN). Note also that the WAN port should be
on a separate VLAN or routing to the WAN may not work. If the WAN port is
assigned to the same VLAN as the LAN ports, then it becomes an additional LAN
port and cannot be used for a WAN connection.
