I have inherited this network and am now having issues with my VPN. We have a static outside (public) IP address block. As far as I know the ASA 5505 configuration has not changed (my motto is "if it ain't broke, don't fix it."). I am running Mac OS X and Windows XP Pro SP3 with all patches. The VPN client is the Cisco software for both platforms.
On the client side I receive the error message:
Secure VPN Connection terminated locally by the Client.
Reason 422: Lost contact with the security gateway. Check your network connection.
I have looked up the error messages for the ASA side and each one is an informational message such as:
Group = allied-vpn, Username = david, IP = xxx.xxx.xxx.xxx, Received unsupported transaction mode attribute: 5
IPAA: DHCP configured, no viable servers found for tunnel-group 'allied-vpn'
Group = allied-vpn, Username = david, IP = xxx.xxx.xxx.xxx, Connection terminated for peer david. Reason: Peer Terminate Remote Proxy 192.168.xxx.xxx, Local Proxy 0.0.0.0
I have included the ASA 5505 current running config.
Any help would be much appreciated.
