Description

Since updating from 2.4.5 to 2.5 I am having an issue with OpenVPN when using "Peer to Peer (SSL/TLS)" mode.

Network access between the two devices (PfSense and Mikrotik) is working properly and I can ping/access devices on either network via the connection, the Mikrotik device admin interface is showing as being connected but the pfSense OpenVPN status page shows no devices are connected. (Screenshot 1)

I have a client specific override setup, which defines which certificate to use, along with some custom routes. (Screenshot 2)

Strangely, I have other OpenVPN connections setup but using the "Remote Access (User Auth)" mode, these work properly and the connected clients are shown in the status page as expected. (Screenshot 3)

The logs indicate a connection being initialised and not showing any errors. (Screenshot 4)
