What network to issue to OVPN clients?

Question

openvpn

Local network 192.168.0.0/24.
gateway: 192.168.0.1
mask: 255.255.255.0
Mikrotik is used as an ovpn server.
At the moment, OVPN clients receive the ip of the local network, for example: 192.168.0.151
As far as I understand, you need to allocate a separate network for OVPN.
What is the best network to choose for ovpn clients?
How can I configure two networks to see each other?

Answer 1

192.168.22.0/24 for example.
10.0.0.10/24 for example
you can take any range from 192.168.0.0/16, 10.0.0.0/8, 172.16.0.0/12 . How convenient.
when adding a network, you will have a route from the local network to OVPN. All you need to do is set up firewall access.
But you will need to configure the return route on the client. depending on what is on the OpenVPN client

Answer 2

10.0.0.1/24 will do.
