SuperTekBoy In The News Search SuperTekBoy...Cisco VPN - Reason 412: The remote peer is no longer responding. January 15, vpn error 412 message 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 http://www.canvassystems.com/blog/articletype/articleview/articleid/14/how-to-fix-cisco-vpn-client-error-412.aspx VPN had 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.

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
