One of the things I wanted from Ipredator which I could not find at the beginning was the ability to have multiple OpenVPN sessions or devices running at the same time.
Apparently there is documentation for this (I and others couldn’t find it) but the friendly staff at Ipredator have given me the tip.
You can use different server addresses to use multiple devices for example:
Device 1: pw.openvpn.ipredator.se
Device 2: nat.openvpn.ipredator.se
nat.openvpn.ipredator.se is a newer address that has been added and using the above I have successfully been connecting two devices at the same time.
