Gluon 2021.1.1

Important notes

Upgrades to v2021.1 and later releases are only supported from releases v2018.2 and later. This is due to migrations that have been removed to simplify maintenance.

Added hardware support


  • Joy-IT

    • JT-OR750i


  • Xiaomi

    • Mi Router 4A (100M Edition)


  • Missing bandwidth limit settings resulted in a respondd crash for v2021.1.

  • The Tunneldigger VPN provider was not registered with the Gluon VPN backend, resulting in broken Tunneldigger configurations.

  • Disabling Radio interfaces in v2021.1 could lead to null pointer dereferences in the respondd airtime module, as the survey returns no data in this case.

Known issues

  • Upgrading EdgeRouter-X from versions before v2020.1.x may lead to a soft-bricked state due to bad blocks on the NAND flash which the NAND driver before this release does not handle well. (#1937)

  • The integration of the BATMAN_V routing algorithm is incomplete.

    • Mesh neighbors don’t appear on the status page. (#1726) Many tools have the BATMAN_IV metric hardcoded, these need to be updated to account for the new throughput metric.

    • Throughput values are not correctly acquired for different interface types. (#1728) This affects virtual interface types like bridges and VXLAN.

  • Default TX power on many Ubiquiti devices is too high, correct offsets are unknown (#94)

    Reducing the TX power in the Advanced Settings is recommended.

  • In configurations without VXLAN, the MAC address of the WAN interface is modified even when Mesh-on-WAN is disabled (#496)

    This may lead to issues in environments where a fixed MAC address is expected (like VMware when promiscuous mode is disallowed).
