Hi,

I'm struggling to set up my VPN connection. I keep getting the same message "The L2TP-VPN server is not responding".

Here is what I've tried.

 

Inside my local network, I've replaced the server domain name on the client by the local IP address of my server and it works.

Inside my local network, I've replaced the server domain name on the client with my domain name and I get the error message.

Inside my local network, I've replaced the server domain name on the client with my global IP address (88....) and I get the error message.

 

My profilemanager, mail server, webdav server is accessible from outside my network so I don't question my DNS provider.

Since the VPN connection is working using local IP address (10.0.0.100) I don't question my VPN configuration.

When I type on my browser (https://mydomainname/profilemanager) it works too so I have no clue what's failing.

 

Any tips, advice?

    Hi,

     

    Did you forward all the correct ports for L2TP towards your server from your router?

    In your router you need to set up port forwarding towards the IP address of your VPN server.

     

    You need to forward the following ports and verify them with yougetsignal to check whether the VPN server can be reached. It should work directly but a reboot of your router might be required depending on the model.

     

    Open up: UDP ports 500, 1701 and 4500 for L2TP tunnelling. You can choose two protocols TCP or UDP, use UDP.

    See here for an extensive overview of all used ports by Apple

    Goodluck!
