VLAN support on the Sophos XG Firewall follows the IEEE 802.1q standards with support for up to 4096 VLANS on the device.
There a 3 reserved VLANs:

  • VLAN 0 is used when a device needs to send priority-tagged frames but does not know in which

    particular VLAN it resides

  • VLAN 1 is reserved for the physical LAN
  • VLAN 4095 is reserved as per the IEEE 802.1q standard. VLAN ID 4095 is a special purpose VLAN ID. When configured it acts Like a trunk port for the vSwitch.

    You can create multiple VLAN interfaces on a single physical interface and allow for tagged as well as untagged traffic on the same physical interface in the XG Firewall.

    Note, you cannot change the native VLAN ID.
