Tagged L2 VLAN thorugh FusionHub

Firstly I’m newbie in Peplink and sorry for dumb questions.
I’ve got 2pcs. of UBR LTE connected to FusionHub on VM, is there any way to pass L2 tagged vlan from FusionHub WAN to Endpoints?

No, only the FusionHub LAN can be bridged with the remote UBRs. You can of course build a L2 bridge between the remote UBRS via the Fusionhub.
