= VLAN (IEEE 802.1Q) =

FreshTomato supports VLAN (Virtual LAN) configurations which conform to the 802.1Q standard. The user can create up to 16 VLANs. A VLAN can use a VID between 1 and 4094.<br />
Please use FreshTomato 2021.8 and newer to make VLANs work properly on ALL ARM and MIPS router. (See examples below.)

<span id="vlan-ethernet-basic-configuration-information"></span>
== VLAN Ethernet (Basic Configuration Information) ==

* VLAN - The VLAN's unique identifier. (VLAN 0 to VLAN 15)
* VID - Allows overriding &quot;traditional&quot; VLAN / VID mapping (Example: VLAN 4 to VID 4) with arbitrary VIDs for each VLAN (set to &quot;0&quot; to use &quot;regular&quot; VLAN/VID mappings instead).
* Ports 1 - 4 &amp; WAN - Specifies which Ethernet ports on the router should be members of this VLAN.
* Tagged - Enable 802.1Q tagging of Ethernet frames on a particular port/VLAN.
* Default - The VLAN ID assigned to untagged frames that the router receives.
* Bridge - Determines if this VLAN ID should be treated as WAN, part of a LAN bridge or just left as is (a member of an 802.1Q trunk, being managed manually via scripts, etcetera).

== VLAN Wireless ==

This section contains the assignments of wireless interfaces to various LAN bridges.

It is highly recommended that you determine and verify the correct settings on the [[virtual_wireless|Virtual Wireless]] and [[network|Network]] menus to ensure proper VLAN operation.

The following settings are also mandatory:

* One VID must be assigned to the WAN interface.
* One VID must be selected as the default.
* To prevent 802.1Q compatibility issues, avoid using VID: &quot;0&quot; . 802.1Q specifies that frames with tag: &quot;0&quot; do not belong to any VLAN (the tag contains only user priority details).<br />
[https://en.wikipedia.org/wiki/IEEE_802.1Q Wikipedia: 802.11Q]
* Avoid using VID: &quot;1&quot; . Some vendors label it as &quot;special&quot; or &quot;reserved&quot; for management purposes.

'''Configuration example for German Telekom ISP'''

Europe's biggest telecom company supports a dual-stack setup (IPv4 &amp; IPv6). For the WAN Port a VLAN tag is required with a value of 7 (VID 7).

== VLAN Notes ==

As mentioned above, for VLANs to function properly, please** use FreshTomato 2021.8 or newer**. All older versions, (including Shibby/Toastman/AdvancedTomato) may not work as expected (see following examples).

<span id="pppoe-connections-with-freshtomato-2021.7-and-older"></span>
==== PPPoE Connections with FreshTomato 2021.7 and older ====

PPPoE connections work only when the following workaround is implemented:

''Example 1'': You are using FreshTomato 2021.7 to connect to German Telekom ISP.<br />
German Telekom uses PPPoE with VID: &quot;7&quot;.<br />
=&gt; you must use VLAN: &quot;7&quot; using VID: &quot;7&quot; (a &quot;traditional&quot; VLAN/VID mapping).

<br />
''Example 2'': You are using FreshTomato 2021.7 to connect to Freedom internet.<br />
Freedom uses PPPoE , and VLAN: &quot;6&quot; using VID: &quot;6&quot;<br />

<br />
''Example 3'': You are using FT 2021.7 to connect to Vivo FTTH (Brazil).<br />
(Vivo use PPPoE, and VLAN: &quot;10&quot; using VID: &quot;10&quot;)<br />
see https://www.linksysinfo.org/index.php?threads/fresh-tomato-r7000-vlan-issue-on-ftth-provider.76958/#post-330955

Starting with release 2021.8, you can select or use any VLAN 0 to 15 (see picture above for example 1 (Telekom ISP), now using VLAN 5 with VID 7)
