IP cameras through ipip tunnel?

Question

Mikrotik

Good day. Faced a problem.
There are 2 offices, each has Mikrotik. An ip tunnel has been raised between routers, since white ip and the same provider.
The network is visible on both sides, I can go to the web face of any device, including the ip camera.

To the registrar at the first location, you need to connect cameras from the second. The registrar does not see the camera from the second location either in manual or in automatic search, but, I repeat, I can access the web-face from the network where the registrar is located.

The question is:
How to show the registrar the presence of cameras at a remote location?

Answer 1

Register each camera manually, it should work.

Answer 2

Will have to do NAT most likely. And redirect the request...
that is, we specify the address of the microt + port for the Regik.
Apparently, the Regik does not like that the IP is from another subnet....

Answer 3

Yes, indeed, the Registrar himself pulled up the data when I simply entered the ip of the camera to him. Question closed, thanks everyone
