set two ports as switch RB951G-2HnD

RouterOS General
1

I am beginner

I have Mikrotik Router model RB951G-2HnD

This is my situation:-

  1. I have a DVR connected to port 3
  2. ISP router connected at port 1
  3. Port 1 works as gateway to deliver internet to my LAN
  4. DVR must connected to ISP router to be accessed from outside
    But can not do it physically.

I need to setup port 1 and 3 of the router as switch and keep other services as it.
My router setting is attached.

My trial:
From Bridge → Ports → ether3-slave-local → Interface ==> change it to all
The DVR connected direct but internet stopped in my LAN

Please help

Okay so here is the problem, it doesnt matter if you can connect your DVR directly to the ISP router or via the MT router
IF… you have no way to access the ISP router.

In other words you would need to be able to port forward at the ISP router to make any server work behind the router, either attached to the ISP router or via the MT router.

I have access and admin to ISP router But I can not physically add a network cable between ISP router and DVR they are connected through mikrotik.
So I need to set direct access between port1 and port3 in mikrotik.

Then you need to port forward the necessary port(s) from the ISP router to the Mikrotik LANIP. Assuming the Mikrotik is getting a private IP on the iSP routers LAN.
Then on the mikrotik you need to port forward the necessary ports to the Server on the MT LAN…

Step 1: Upgrade firmware to Stable 7.6, I personally wouldnt trust any 7 firmware before 7.6.

Step2: Add port forwarding dst nat rule for your Server…

Thus someone coming in from the outside will hit the ISP router which will forward request to MT which will forward request to server
