VPN Connectivity

[andy]

We operate most phones within our LAN, but I have 2-3 phones at a remote location. Those should ideally connect through our VPN to the PBXNSIP server.

 

First question: Should this simple configuration work with PBXNSIP? So far it does not.

 

PBXNSIP server is on IP 192.168.26.130/Subnet: 255.255.255.192

Remote phone (Snom320) is on IP 192.168.26.26/Subnet: 255.255.255.240

Server and phone are using the same DNS: 192.168.26.130

 

All ports are open within the VPN, but the Snom320 reports: Network Failure.

 

 

Second question:

 

Would it be better to set up a second (smaller) PBXNSIP server at the remote location and connect both servers in order to get this stable?

 

I am not sure to do from the info I got from the forum so far.

From the PBX perspecitve VPN is just like any other network interface. In the setup above, the different netmask raise a question.

 

If you are using snom, why do you want to use VPN? You can as well just connect the phone directly through TLS and SRTP to the PBX.

 

Maybe you can try to set up a laptop with VPN and try to register a softphone first. That is probably a good way to verify that the setup is okay.
