First off I am trying to Remotely connect a user to the Insider Server directory at my company and Need to use the VPN. We have a PIX 501 Version 6.3(5), PDM Version 3.0(4). It was originally set up by a 3rd party that we hired to get the entire Server up and running, they have however gone out of buisness since then and I cannot find anyone locally to help me with this. I am fairly adept at keeping everything running, and we have not needed to use the VPN for a while, but it seems that the VPN configuration may need to be redone. I have used the VPN Wizzard to set up the VPN, and have tried to use another computer on another Internet source to try to connect to the VPN, however my VPN client keeps getting a 'Reason 412: The remote peer is no longer responding' Is ther any easy way to get this set up?
If all clent logs have been enabled, the client log suggest the firewall is not responding to ike at all. Maybe udp 500 is being blocked elsewhere in the path.
Are you certain the dhcp ip you rceive, is the ip address you are trying to connect too?
For seeing more logs on ASA
You need to issue "logging buffered debug", "clear log" and then do show log.
Otherwise, once you enable the debug commands, and you got access to the console (serial - CLI) you should see the log messages being output, when you have client trying to connect.
