The VPN Connections app in the Market is suppose to work with a rooted Droid running 2.0.1. See the wiki page on the right:

Unfortunately I cannot seem to get this to work. I'm trying to connect to a Cisco ASA which is the same device I connect to using the Cisco VPN client on my WinXP box.
I have busybox installed and working, and also have the tun.ko module installed and loaded. But it still won't connect. See the comments on the above mentioned wiki for the additional steps taken as well as my comments of the problem I'm seeing.
Anyone here play with this and get it working? Specifically with an ASA appliance? I have a 3000 unit I'm going to try when I get back into the office on Monday.
