Traffic Between hosts

[Guest]

[kyeto]

Hello,

I'm using the v2.4.1.
I use OpenVPN to connect all my server.

I have check the button to allow traffic between host in the VPN tab.
But i want rules between hosts.
Example :
Server 1 <=> Server 2
Server 2 <=> Server 3
But the server 1 and 3 doesn't right to exchange information.

I have enter some rules in the Firewall => VPN Traffic but it doesn't work. All host can join the others
My rules use OpenVPN user.

Thanks
