Configuring Router VLAN Settings

Follow

 

This section of the router configuration allows you to add, remove and configure VLAN interfaces, including their physical port assignments and IP address settings. This allows the router to send and received VLAN tagged traffic from the LAN. The handling of untagged traffic is configured in the “LAN Settings” section.

By default there are no VLANs configured, to add one, simply click the “+ Add VLAN” button.

VLAN ID

This is the VLAN ID that will be used for this interface. This value should be configured to match the VLAN ID used on your network switch or other network device. Any VLAN can be used except for the system reserved VLAN IDs of 1, 991, 992, 993, and 994, there is no limit to the number of VLAN interfaces that can be created.

 

Ports

This selects which router LAN interfaces this VLAN will operate on. At least one interface must be selected to create the VLAN interface, however all four interfaces can be selected as well if desired.

 

Gateway IP

This IP address will be installed on the router as a gateway IP for clients operating within the VLAN. This IP address will also be advertised in the default DHCP server instance the router will operate on this VLAN interface as the networks default gateway. (Example: 10.1.1.1)

 

Subnet Mask

The subnet mask for the IP network, this will define how large or how many IP addresses will be available for use in the VLAN. (Example: 255.255.255.0)

 

DHCP Pool Start

This is the first IP address in a range that the routers default DHCP service will offer to client devices that connect to the VLAN. Addresses will be provided sequentially starting from this address. (Example: 10.1.1.2)

 

DHCP Pool End

The is the last IP address in the range that routers DHCP service offers address from. (Example: 10.1.1.254)

 

DHCP Lease Time

This is how long an address lease offered by this VLANs DHCP server will last for. This can be set for any value between 5 minutes and 7 days, the default value is 12 hours. A good rule of thumb is that the more devices that come and go from the network, the shorter the lease time should be (e.g. Public Wifi network), while for more unchanging network environments (Wired office network) longer lease times are preferred.

 

DHCP Reservations

A DHCP Reservation will allow you to “Statically” assign an IP address from the DHCP Pool range to a specific client device. This will ensure that the device will always be assigned the same IP address, allowing the reliability of static addressing with the management ease of dynamic address assignment.
