Unable to ping vpn clients from LAN

[coffen]

Hi
I have set up a vpn server on Zentyal. The LAN ip for the Zentyal server is 10.10.15.3.
In the vpn server config, the VPN address is 192.168.160.0/24
The vpn server advertises the LAN network 10.10.15.0/24

When I connect with my laptop using openvpn the vpn server assigns me an ip, for example 192.168.160.6
From the laptop I can ping any computer with the ip 10.10.15.x

From the Zentyal server Network -> Tools -> Ping, I can ping the laptop.
If I do a ssh connection the the zentyal server, I can also ping the laptop from the Zentyal server terminal.

My problem is that I cannot ping my laptop from the any of the LAN (10.10.15.x) computers.
