Create OpenVPN server for GrandStream DP750

[BlazeStar]

Hello,

I own a Netgate 3100

It's running pfSense 22.05-RELEASE

I would like to set a new OpenVPN server so I can get my GrandStream DP750 to connect to it.

The problem is that the settings are VERY basic :

So right now, I tried to set up a new OpenVPN server in pfSense:

• MODE : SSL/TLS + User Auth
• tun - Layer 3 Tunnel Mode
• UPD on IPv4
• TLS Authentication
• Auth digest algo: AES-256-CBC
• IPv4 Local network: only the IP of the VoIP server /32

On the GrandStream DP750 side I entered:

• The server address and port
• I uploaded the CA that I got from pfSense in System > Certificate Manager > CAs
• I uploaded the Certificat that I got from pfSense in System > Certificate Manager > Certificates
• I uploaded the Key that I got from pfSense in OpenVPN > Client Export Utility
• Cipher Method: I selected AES-256
• Username and Password have been double-checked
• I disabled Comp-lzo
• No additional options

It doesn't work !

I don't know what I'm doing wrong :(

Any idea?

@blazestar
Any hints in the log?

I currently try to set that up with a GXP2160

@BlazeStar did you succeed?

I plan to set up a rather minimal ovpn-server just for the phones.
The WebGUI of the phone is quite bad and gives no good status or feedback etc

Not even logs ...
