Open VPN netmask 255.25.255.252

lanzao

I'm getting the tunnel, but with this mask 255.255.255.252. I need 24-bit chews.
What is wrong?
Need any virtual network route to the openvpn?

On OpenVPN Server you set the tunnel network. for example

10.10.10.0/24

10.10.10.0/30 is the OpenVPN Server itself
10.10.10.4/30 is the first OpenVPN client which connects
10.10.10.8/30 is the second OpenVPN client which connects
….
10.10.10.252/30 is the 63rd OpenVPN client which connects.

In short:
Every client connection on OpenVPN needs a subnet of /30

First IP: Network IP
Second IP: OpenVPN Server IP
Third IP: OpenVPN Client IP
Foruth IP: Broadcast IP

This is how every client connection/subnet looks like.
