Bug with gateway monitoring and topology /30
-
Hi,
With a OpenVPN client and /30 topology, local IP is localhost address and remote IP is gateway address.
When gateway monitoring is enabled, pinger monitor only local IP address, so, it's impossible to detect a packet loose or latency. Sometime, tunnel is up but no traffic pass in the tunnel (trouble on server or client), pinger is unable to detect the problem and load balacing not work.
pfSense should use remote IP for monitoring gateway instead of local local IP address (gateway can't fixed with dynamic allocation) ?
Another problem, the remote host on Status/OpenVPN/Client Instance Statistics is not correctly updated. If I start/stop the tunnel, Virtual Addres is updated, but not Remote Host. I don't know if remote host is use for something else.
Regards,

With /30 topology the server address in the /30 is completely virtual and often cannot be pinged. You have to set your own monitor IP address for that case, it can't be automatically determined in a reliable way.
For the status, that is pulled directly from OpenVPN's management interface. If it's wrong, it's a bug or quirk in OpenVPN's behavior, so you'll have to raise the issue upstream with OpenVPN directly.

I can't set the gateway manually because the gateway change at each connexion. Again, it's usefull to ping local IP address, it could be nice if user sould be able to choose dynamic remote address.

You're right, I confirm the IP address is wrong in OpenVPN interface, I'll check with openvpn project.
For that moment, do you know if it's possible to push the new gateway IP address manually to pinger with a script (without pfSense GUI) ?
Thank you,
