Setup Road Warrior within same broadcast domain

HI all,

I’ve been breaking my head over a question to which i can’t seem to find an answer.
I need a setup to connect a single Road Warrior / Teleworker to a office subnet, but it’s imperative he stays within the same broadcast domain as the office subnet.
The teleworker will need to access an application which relies on UDP broadcast only.

The office has an CCR2004 router, with RouterOS 7.3.1.
The teleworker has an W10 tablet with LTE or WiFi connection to internet.

Is this possible?!

broadcast domain is typically at level2 I believe and most VPNs are not.
Zerotier connectivity is at level2 and is your best bet for success.

Wireguard with EOIP on top of it if both sides are Mikrotik.
Since you only have one on 1 side, you could use a map or AX lite for road warrior connection.

Zerotier is indeed your best option. Works surprisingly well (e.g. ROMON discovery over ZT, no-brainer).
