Strongswan VPN basic network configuration

Hey, I’ve set up a Ubuntu 16.04 vps and fired up a Strongswan VPN. I managed to connect to the VPN with Windows client as well with my DVR with GSM modem.

When I hit ipconfig on windows client amont others I get:

PPP adapter DO VPN:

Connection-specific DNS Suffix . : IPv4 Address. . . . . . . . . . . : 10.10.10.1 Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 0.0.0.0

Also, when visitng whatismyip I get my VPSs IP address so routing is working fine.

What I actually want to do is to have access to other clients on the VPN network. Is that at all possible cause I got confused?

When I try to ping my windows client vpn address 10.10.10.1 from the server I get nothing:

Is is something with configuration or maybe you have to connect server as a client as well? As you can see I am begginner here.

Thanks a lot,
