Setting up a Grandstream GXV3240 on Untangle IPSec VPN

[gpeters]

I need help setting up the Grandstream GXV3240 phone using the built-in VPN. The phone will be at a remote location with a dynamic IP address. How can I setup a IPsec Tunnel if the IP will be static and could change any time?

You can't use IPsec tunnel, but use L2TP or Xauth for endpoint tunneling.

Never mind. I notice when I go through the andriod interface I can install the OpenVPN app

So I tried the Open VPN client and that does not work. I can connect to the Untangle OpenVPN with the phone at the remote location.

Now I just tried L2TP and Xauth and the VPN connects fine to Untangle.

But still not connected to the FreePBX server

Does anyone else have experience with this?

Both VPNs are routed, you can't just "connect". You need to configure your PBX to properly handle the IP ranges in question.
