Hi Ian, thanks for your kind words. I can't take screenshots easily so I'll just have to describe the settings. Here goes:

First go to the settings app, then choose WiFi, turn it on and select the network 'NUIMWireless'.

Then go back to the settings home screen, select "General" then "Network" and then "VPN". In there choose "Settings". Choose PPTP, set the server to "nuimwireless", set the account to your student number, leave RSA Secure ID at off, enter your password, leave the encryption level at auto, make sure send all traffic is set to on and then scroll right down to the proxy settings. Choose "Auto" and enter the URL: http://proxy.nuim.ie:8010.

Hit save, go right back to the settings home page and hit the on switch next to VPN and you're away.

In the future you just have to turn on wireless and then VPN whenever you're on campus. You don't need to re-configure the VPN each time.

Hope that helps!

Bart.
