Hi Science,
Our network does not use a Public IP addressing system, which can often cause problems for certain VPN configurations. Luckily, provided you have the correct settings in place, this should be fixable.
You'll need to read through the VPN Overview, as well as the applicable VPN guide for the type of VPN that Sonicwall uses, so that you will know what needs to be in place both at the client and server end, in order for your VPN connection to be made possible over the Vodafone Network.
These guides can be found
here
I trust that helps.
