TAP VPN Hub - creating layer 2 connection for Industrial Networks

Hello,
I’m trying to set up a Teltonika remote router using a TAP VPN HUB. My goal is to use it as a remote access to an Industrial Network for a programists. For that I need it to be in a Layer 2 soo broadcast need to work. I’ve managed to configure it using new beta TAP VPN HUB by creating a bridge between tap_ network and LAN network, however it only works if I change address into that local network subnet. I cannot change IP address DHCP in TAP Mode and also it in about 5 minutes changes my local network adapter into address from DHCP.

I want to clarify if I’m approaching it the right way or there is a better way to achive same goal.

Thank you in advance.
