There is no traffic between L2TP clients. Server: Mikrotik v6.35.2 Which way to dig?

Question

Ping

Good time of the day!
There is a Mikrotik, 951st, it has an L2TP server. There are only two clients that are behind nat, and they need to be combined into one network. Mikrotik has a white address, the connection is configured, clients pass authorization, authentication, they receive addresses from the pool. But the ping does not pass from one client to another. At the same time, the ping from the client to Mikrotik goes through the vpn tunnel. Ping from Mikrotik does not go to the client.
On Mikrotik, both l2tp connections are combined into a bridge. The firewall has nothing to do with it, I tried it with allowing rules. NAT on Mikrotik is configured in such a way that traffic from the virtual subnet (192.168.50.0/24) does not flow.
To configure, I used the following resources:

Tell me, what could be the ambush? I'm sure some little thing is very important.
Thanks in advance.

Answer 1

VPN and LAN are on the same network?
Ping from Mikrotik must be passed through the VPN interface (this is how ping should go through the tunnel).
Most likely there can be a problem in routing.

upd: instructions on the link are crazy. turning on proxy-arp and stuffing it all into the bridge is just fire.

Answer 3

Thanks for your help,
issue resolved.
It turned out:
1. The bridge is really superfluous.
2. The routes were normal, the addressing in the l2tp tunnel was its own.
3. The firewall on client computers interfered.
