Title: VLAN behavior of default LAN interface?
Post by: Asperamanca on February 01, 2021, 10:29:15 am

If I connect the default LAN interface to a VLAN-capable switch, will the LAN interface tag packets with (default) VLAN id 1, or send untagged packets?
In reverse, will LAN interface drop packets tagged with VLAN id 1 or accept them?

VLAN1 will be untagged by default.

If you then TAG packets on a port for VLAN1, then the LAN interface should accept it.
