Sonicwall recently released an iPAD client for their newer Secure Remote Access (SRA) SSL VPN Appliances, NSA and E Class firewalls called Sonicwall Mobile Connect. It's a free download available from the App Store at http://itunes.apple.com/us/app/sonicwall-mobile-connect/id466931806?mt=8. Setup is really simple and works well with the SRA1200. For remote desktop access you can download an iPAD RDP Client like Wyse PocketCloudPro http://itunes.apple.com/us/app/wyse-pocketcloud-pro-remote/id326512817?mt=8 to gain access to a remote desktop.
Great solution if you want to travel light!
