VLAN (IEEE 802.1Q)

FreshTomato supports VLAN (Virtual LAN) configurations. The user can create up to 16 VLANs. A VLAN can use a VID between 1 and 4094.
Please use FreshTomato 2021.8 and newer to make VLANs work properly on ALL ARM and MIPS router. (See examples below.)

VLAN Ethernet (Basic Configuration Information)

  • VLAN - The VLAN's unique identifier. (VLAN 0 to VLAN 15)
  • VID - Allows overriding “traditional” VLAN / VID mapping (Example: VLAN 4 to VID 4) with arbitrary VIDs for each VLAN (set to “0” to use “regular” VLAN/VID mappings instead).
  • Ports 1 - 4 & 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 and 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: “0” . 802.1Q specifies that frames with tag: “0” do not belong to any VLAN (the tag contains only user priority details).
    Wikipedia: 802.11Q
  • Avoid using VID: “1” . Some vendors label it as “special” or “reserved” for management purposes.



Configuration example for German Telekom ISP

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

VLAN Notes

For VLANs to function properly, please use FreshTomato 2021.8 or newer. All older versions, (including Shibby/Toastman/AdvancedTomato) may not work as expected.

PPPoE connectios only work using the following workaround:

Example 1: You are using FreshTomato 2021.7 to connect to German Telekom ISP. This uses PPPoE with VID 7. ⇒ you must use VLAN “7” using VID “7” (a “traditional” VLAN/VID mapping).

Example 2: You are using FreshTomato 2021.7 to connect to Freedom internet. Freedom uses PPPoE , only possible with VLAN 6 using VID 6) see https://www.linksysinfo.org/index.php?threads/fork-freshtomato-arm-development-discussion-only-for-support-always-open-your-own-thread.74117/page-245#post-330148

(Example 3: If you are using FT 2021.7 to connect to Vivo FTTH (Brazil) (needs PPPoE, only possible with VLAN 10 using VID 10) 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)
