<![CDATA[Inter-client communication Setting]]>Inter-client communication - Allow communication between clients connected to this server

That option is NOT selected but VPN clients are able to ping each other.  According to the description that seems to be not working correctly.  Or am I missing something?

With Inter-client communication inactive, firewall rules apply.
So if you want to block that, make rules on VPN interface.

100% block OpenVPN traffic is only possible if..
..Inter-client communication disabled
..no firewall rule match on the pfSense OpenVPN interface

Right?
There is no change in OpenVPN 2.5 or?

With Inter-client communication active, firewall rules do not apply.
This is because in that case packets are routed internal to OpenVPN and pfSense does not see those packets at all.

I wonder what is that option for ?

I'm using version "2.3.4-RELEASE-p1 (amd64)  built on Fri Jul 14 14:52:43 CDT 2017  FreeBSD 10.3-RELEASE-p19"  and still the same situation or any has found another solution?

Can anyone confirm either in the affirmative or negative that the Inter-client communication option works correctly (not enabled prevents VPN clients from communicating / pinging each other)?
