How to forward camera traffic in L2TP on Mikrotik?

Question

VPN

Good afternoon.
We have ubuntu-server with l2tp + Mikrotik router as l2tp client.
The rules are as follows: https://pastebin.com/raw/SbzUqQGu

I forward ports 1936,1937,810,811 in L2TP for external control (control via xrdp directly on the server).
Everything works fine on OpenVPN.

But when you try to reconfigure forwarding to L2TP with almost the same settings (using the link l2tp forwarding), then the rtmp stream does not go. But 810,811 ports with web-based camera control work.

Torch has the following (screenshot). When the server tries to connect to the local L2TP address, 5-7 kb appears in Torch and that's it. That is, the forwarding somehow worked, but the stream from the camera does not go. (but at the same time, management opens on ports 810 and 811)

The essence is exactly the same as in OpenVPN ...
