Greetings. I bought these units a few years ago to extend internet access to my shop about 100 meters away. I ended up just installing a second circuit in the shop. We recently had a huge wildfire in our area that burned much of my ISP’s infrastructure. They will be down for weeks, if they come back at all. My interim solution is a 5G router from T-mobile. They are cheap enough that I could just get a second unit for the shop, but I dusted these off and want to give them a try. Previously, I ran an IPSEC tunnel to the shop from my house. An L2 connection would allow me to take the shop firewall\router out of the architecture and save me a big licensing bill from Fortinet. I got Winbox running with WINE and upgraded the OS in both units to 7.11. I want a simple PTP bridge, but I have not had any success reading the documentation. Any help would be appreciated. Thanks.
They look like very simple RouterOS devices:

All I know about these devices is above. I’m providing a generic RouterOS answer.
Choose two static IP address from your house subnet for assignment to both devices.
On both devices create a bridge /interface bridge add …
On both devices add Ethernet port and WLAN port to respective bridge.
Assign bridge interface on each device it’s selected IP address
Once both ports are added to bridge then each device becomes a smart two port switch.
The tricky part is maintaining connection over old IP during bridge create before new IP comes up. Once bridge has both ports as members, a member port with an IP address is a misconfiguration. But if it keeps working until after new IP is assigned to bridge interface then connect to new IP address and remove old IP address.
Remember this is generally sound but particularly speculative. Be prepared to reset device and start over.
