I had to laugh when I read your post as I am sitting in my office waiting for a call back from IT on configuring my iPad to connect to AC via VPN in my office so I can carry it from room to room.
Why would you need to VPN in your own office? VPNs are to make it seems like you're on the LAN when you're in a remote location. You're already on the LAN with WiFi. You're probably trying to access AC using your external IP when you need to use your internal IP.
Anyways, you should be able to use that Jump App locally. You just need to change the IP Address to your workstation's IP address. Usually 192.168.X.X or the Net Bios name (e.g. DAVESERVER).
iPads are far from my future lol.
