Cisco ASA – Remote IPSEC VPN With the NCP Entry Client
KB ID 0001260 Problem I’ve covered Cisco IPSEC Remote VPNs a long time ago, and I’ve also blogged about the Cisco IPSEC VPN Client Software. Yes you can get the Cisco VPN Client Working on Windows 10, but can you imagine rolling that out to a few hundred users? The bottom line is Remote Cisco IPSEC VPN is a dead technology, Cisco, (and Me!) want you to use AnyConnect. For a couple of users you can use the work arounds...

Cisco VPN Client Connects but no traffic will Pass
Note: May also be asked as, Client VPN connects but cannot ping anything behind the Firewall.
