iPhone IOS, iPad or Mac OSX to DrayTek Vigor 2860 or 3900 via VPN Connection

The newer Mac and IOS versions no longer support the Microsoft PPTP versions and so connecting to your office or home has become more difficult unless you are using MAC OSX Server or similar. Here we are going to go over how to connect your IOS or OSX device to your DrayTek router so that you can use your local LAN or browse the internet as if you were back at home.

If you are looking for a service to connect you to the UK for internet browsing whilst abroad, please feel free to enquire about our UK VPN dial-in services.

First of all log in to your router control panel as normal, in this case we are looking at a 3900, but the 2860 is the same:

 

 

Firstly, we are using an L2TP over IPSec connection in this instance, so let's make sure that the services are being supported. Go to VPN and Remote Access and then Remote Access Control and make sure that the L2TP and IPSec services are enabled, as below:

 

 

Next we need to set-up the IPSec pre-shared secret. To do this we go to IPSec General Setup and enter the shared secret that all of the IPSec sial-in users will need to have:

 

 

In this example we are leaving the incoming internet port as WAN1 and the internal network DHCP profile as LAN1 but you should configure these as appropriate for your network.

Now if you are using the router's DHCP services then you can skip the next step but in this example the 3900 is part of a Windows server network and the servers provide DHCP and so we are going to configure the router to pass on the DHCP from the server as the users will need to access the server network remotely. To this end we go to PPP General Setup and click the L2TP tab at the top:

 

From the above I am selecting to enable DHCP and choosing the DHCP Server Location as LAN1 as it is in this case. I then enter the DHCP Server IP Address with the Windows Server providing the DHCP services. 

 

Go to User Management and then User Profiles and select Add:

 

 

Enter the details of the user and click the tick box to enable the VPN. Scroll down to the PPTP/L2TP/SSL section and enable L2TP Dial-in for this user and then click Apply:

 

 

Now you can set-up your IOS or OSX Apple clients:

Go to Settings then General and select VPN and Add new VPN configuration:

 

 

Change the VPN type to L2TP

 

 

 

 

Now enter the details you entered for the VPN user:

 

 

 

Once you have entered the details, click Done.

Now go back to the settings page, find the VPN option and click the slider on the right to start the VPN:

 

 

Once the VPN has connected you will be able to see the VPN icon at the top of your screen:
