If you see “Secure VPN connection terminated locally by the client. Reason 412″ it means that the software VPN client detected that the VPN server isn’t responding and has deleted the connection. Cisco VPN error 412 – What Causes it? The following are the main causes of a VPN 412 error: You’re behind a firewall that’s blocking ports UDP 4500/500 and/or ESP. The VPN client is using connecting on TCP and the default TCP port 10000 for NAT-T is blocked. Your internet connection isn’t stable and some packets aren’t reaching the concentrator/server or the replies from the server/concentrator aren’t getting to the client. The VPN client is behind a NAT device

January 15, 2014 By Gareth Gudger 7 Comments 4 Shares Share Tweet +1 Share RedditI ran into this issue recently while trying to make a Remote Access VPN work on a Cisco ASA 5505 firewall. The VPN had cisco vpn been working at one point but was rarely used. When the end user tried to use it again they kept getting the following error. Secure VPN connection terminated locally by the Client. Reason 412. The remote peer is no longer responding. Now this error could occur for many reasons. Including a firewall on the client side that is blocking the necessary UDP or TCP ports, cisco vpn error or, an unstable internet connection, such as a mobile connection. But in my particular case it was actually a configuration issue on the firewall itself. On this particular firewall there was a NAT statement that was translating everything from interface to a server on the private network. The syntax looked something like this. static (inside,outside) tcp interface DALEK-KHAN mask 255.255.255.255 I'm not really a big fan of the interface syntax. The interface syntax is specified when you want to use the IP attached to the outside interface for PAT (Port Address Translation). I prefer to use a dedicated public IP for my Cisco device and keep address translation on their own IPs. However, for various reasons, whether it be cost prohibitive, or, limited provider plans, there is a definite need for this syntax. The problem with our code was that every TCP port was being translated from the external interface to an internal server. Even the ports required for VPN connectivity! This was the cause of our error. Removing this NAT statement, and replacing it with just the PAT statements that the server actually needed, freed up the necessary VPN ports. So, for our server DALEK-KHAN, let's make him a webserver,
