VPN on IPAD/IPHONE

[hugoj]

Hello,

I have a bit of a weird issue.
At home I have setup a VPN with a Raspberry Pi.
I have a laptop, ipad/iphone (with IOS6) and an Android phone.

When I am in the office I can connect to the VPN with all devices and I can go to the internet via the VPN.

When I am in my friends house, I also can connect to the VPN with all devices. However, with the Ipad and IPhone I do not have internet access. With my laptop and Android phone I am connected to the internet via the VPN.

Does anyone have an idea what the reason could be and how to solve this? Is there perhaps an alternative client I can use on my Ipad/Iphone?

Thanks a lot for your help

Is your VPN supporting compatible protocols?

Hi Tim,

Thanks for your reply. Yes, I am using the PPTP protocol with password authentication.
Also, if I would be using a wrong protocol/authentication, I would not be able to connect correctly from my office.

I may be misunderstanding your setup. If the Raspberry Pi is terminating the VPN tunnel, then VPN client support on your devices isn't needed.

Can you clarify how the Rasberry Pi is being used?

Could both your house and your friend's network be using the same subnet?

I have setup the VPN on the Raspberry following these instructions:

If the subnet would not fit, I assume I would not be able to connect with my PC and Android phone.

The Raspberry is not terminating the tunnel. I can access the Raspberry iteself, the part that is not working is the internet connection.

The subnet question concerns routing. How the VPN client handles identical inside/outside subnets can vary between clients.

Thanks for your quick reply.
I am afraid I am a bit lost here - I am not an expert in this area.

In the vpn client on my Ipad there is not a lot to configure.
How can i see the subnets that are used on both the Ipad and my android phone?

Thanks
Hugo

Many devices provide a network connection/status page, which displays the device IP. As IPs are usually provided by the network, this IP often changes depending on the network you are currently connected to. The network subnet can be deduced from the client IP and subnet mask. For your friend's, you'd have to either check the IP next time you visit, or ask him/her what an IP of a device on the network is.

If, for example, both your network and your friend's are assigned to the 192.168.1.X subnet, then the client or raspberry pi may be incorrectly deciding the network to which traffic should be sent.

Static WAN IP?

Do you have a static IP from your ISP or are you using a Dynamic DNS provider?

If you are using a Dynamic DNS are you able to connect to your home network without using VPN. Probably want to do this using a web browser on both your Ipod and Iphone.

Once you can do that then you can experiment using connecting the VPN clients on your portable devices. As mentioned you may not need to use the VPN function remotely.
