CAX30 onboard VPN

Has anybody used the onboard VPN on a CAX30 router?

 

I have been trying for days to get it to function. I have successfully gotten the DDNS

entry to work and can successfully ping the hostname.

 

I have downloaded the various configuration files and had to integrate the files into the single

.ovpn file required for the current OpenVPN client connect software.

 

I have tried OpenVPN clients on both my iphone and my macpro with no success.

Both clients timeout.

 

I don't see anywhere in the CAX interface that reports VPN status.

 

I have enabled VPN log messages on the CAX30 and see no log messages or event log entries

related to VPN service being active or started or attempts to connect. I do see the DDNS being

successfully updated at startup.

 

Given the flaky state of the CAX30 firmware, I am looking for confirmation from ANYBODY who has

actually gotten the onboard VPN to work on this device with any client.

 

Thanks in advance,

sryan

        Just a reminder, you cannot test a client device that is connected to the same network where the server (router) is connected.  On a mobile device, you have to turn off Wi-Fi and connect to the internet through cell data.

         

        I am a Windows/Android type and use the operating system specific OpenVPN applications.  You do not have to manipulate either configuration set to install/import for these operating systems.  Downloaded from the router in a zip file, the Windows configuration set is four files and the Android is one file.
