How to set up MikroTik VPN Routing?

Question

VPN

Hello. Tell me please.
We have 3 MikroTik .
1. MikroTik VPN server with IP 192.168.0.1
2. MikroTik VPN client with IP 10.20.1.10 (internal network with IP 192.168.2.1/24 )
3. MikroTik VPN client with IP 10.20.1.11 (internal network with IP 192.168.3.1/ 24)
4. MikroTik VPN client with IP 10.20.1.12 (internal network with IP 192.168.4.1/24)
Computers from internal networks cannot see each other. That is, a computer with IP 192.168.2.50 does not see a computer with IP 192.168.3.20 or 192.168.4.5.
In general, neither as computers from different VPNs do not exchange with each other.
Please tell me how to register routes. That it was a uniform network? So that computers from different VPN networks can see each other.
Thanks

Answer 1

If you don’t bother too much, then on each client router, add a static route for the 192.168.0.0/21 network, and specify the vpn server address as the gateway (from the 10.20.1.0/24 network)

Answer 2

Raise static / dynamic (ospf / bgp) routing between routers, allow traffic forward in the firewall, if necessary, and use

Answer 3

The computer with IP 192.168.2.50 does not see the computer with IP 192.168.3.20 correctly, you have the mask /24
