VLAN (IEEE 802.1Q)

FreshTomato does support VLAN setups and the user can create up to 16 VLANs. Any VLAN can use a VID between 1 to 4094.

Basic Infos for the setup

  • VLAN - Unique identifier of a VLAN. (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 - 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 - VLAN ID assigned to untagged frames received by the router.
  • Bridge - Determines if this VLAN ID should be treated as WAN, part of a LAN bridge or just left alone (i.e. member of a 802.1Q trunk, being managed manually via scripts, etc…).

Wireless - Assignments of wireless interfaces to different LAN briges. You should probably be using and/or check things on Advanced/Virtual Wireless and Basic/Network.

Other relevant notes/hints:

  • One VID must be assigned to WAN.
  • One VID must be selected as the default.
  • To prevent 802.1Q compatibility issues, avoid using VID “0” as 802.1Q specifies that frames with a tag of “0” do not belong to any VLAN (the tag contains only user priority information).
  • It may be also recommended to avoid using VID “1” as some vendors consider it special/reserved (for management purposes).

Configuration example for German Telekom ISP

Europe's biggest telecommunications company supports a dual-stack setup (IPv4 & IPv6) and for the WAN Port you need a VLAN tag with the value of 7 (VID 7).

IMPORTANT NOTE: please use FreshTomato 2021.8 and newer to have VLAN working properly.

All “older” versions (including shibby/toastman/AdvancedTomato/etc.) may not work like expected. PPPoE connection is only possible with the following “workaround”.

Example 1: If you are using FT 2021.7 to connect to German Telekom ISP (needs PPPoE with VID 7) ⇒ you have to use VLAN 7 using VID 7 (“traditional” VLAN/VID mapping)

Example 2: If you are using FT 2021.7 to connect to Freedom internet ( needs PPPoE, only possible with VLAN 6 using VID 6) see

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

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)
