I'm looking for two apps for my new Galaxy Tab 10.1. I need a VPN app that'll let me input a group authentication username and password. There is a Cisco app for the iPad, but I can't find one for Android. I've also got a NAS on my home network that I'd like to be able to browse. I'm not in front of it right now, but I believe it'll share over cifs/smb and nfs. What is the best app that'll let me access the files over my network? Thanks.
