I am setting up a new ASA 5520. I am having a little bit of trouble getting the vpn connection up and going I tried both CLI and ASDM VPN wizard with no luck. So I removed everything and tried again from CLI still no luck. Hopefully someone can point out what I am missing. Here is what I currently have for the VPN config. Right now I don't care about split-tunnel so I have left it out.

How are you testing, and what are your symptoms.
Are you testing from actually outside the firewall?
What version client are you using?
Do you get connected at all? If not, what error messages do you get?

I am trying to connect from outside the network with cisco vpn client version 4.800.0.440. I don't get any error messages the client just tries to connec and eventually stops trying and says not connected.

Can you ping the public IP of the ASA from the client PC?
Open the log window on the client when you try to connect and post the result.

Do you have any acls on the router in front of this ASA? I'm assuming this is followup to an earlier thread with same configuration?
