The Vigor router supports up to 16 VLANs. Each VLAN can be set up to use one or more of the
Ethernet ports and wireless LAN Service Set Identifiers (SSIDs). Within the grid of VLANs
(horizontal rows) and LAN interfaces (vertical columns),
 all hosts within the same VLAN (horizontal row) are visible to one another
 all hosts connected to the same LAN or WLAN interface (vertical column) are visible to
one another if
- they belong to the same VLAN, or
- they belong to different VLANs, and inter-LAN routing (LAN>>General Setup) between
them is enabled (see below).
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.
Vigor2926 series features a hugely flexible VLAN system. In its simplest form, each of the
Gigabit LAN ports can be isolated from each other, for example to feed different companies
or departments but keeping their local traffic completely separated.
