VPN software question from a Blackberry user

[wetling]

I've got a BB now, but am considering the Moto Droid as my next phone. One requirement I have before switching is that I need to be able to access internal company websites from the phone.

I understand that I'll need a VPN client to make the sites accessible to an Android phone but I don't see any that will work with our 2-tiered authentication setup.

On a PC, we install the Cisco VPN client and enter shared credentials in the connection entry. Then, when we connect, we enter our user credentials and are granted access. Are there any VPN clients for Android that'll work for me?

Thanks.
