I have two Untangle boxes setup and working, both with static public IP addresses. I would like to setup a VPN between the two but I'm having some difficulty. I have one Untangle box configured as the server just fine. But when I try to setup the second box as a Client, I get an error when I try to download the VPN configuration from the server. It says "Your VPN Client configuration could not be downloaded from the server. Please try again." I don't have physical access to either server so I can't use the USB key. But does anyone know why the server download would fail? Is there something else I have to do on the server side to make it allow the connection from the other server? I have tried turning off all the modules except Router but it still gives the same error.
