If this connection is attempting to use an L2TP/IPsec tunnel, the security parameters required for IPsec negotiation might not be configured properly. Possible Cause: This error comes when the VPN tunnel type is ‘Automatic’ http://www.howtogeek.com/forum/topic/vpn-error-809 and the connection establishment fails for all the VPN tunnels. Possible Solutions: a> If you know which tunnel should actually be used for your deployment, try to set the ‘Type of VPN’ to that particular tunnel type on the VPN client side. [This can be set by clicking the ‘Network Connections’ icon on the bottom right of the task bar, Select your Connection, Right Click -> Properties https://blogs.technet.microsoft.com/rrasblog/2009/08/12/troubleshooting-common-vpn-related-errors/ -> Securities Tab -> Under ‘Type of VPN’ select the interested VPN tunnel type ] By making VPN connection with a particular tunnel type, your connection will still fail but it will give a more tunnel specific error (for example: GRE blocked for PPTP, Certificate error for L2TP, SSL negotiation errors for SSTP, etc.) b> This error usually comes when the VPN server is not reachable or the tunnel establishment fails. i. Make sure the VPN server is reachable (try to PING the server). ii. If interested in PPTP, make sure PPTP port (TCP 1723) or GRE Port (47) is not blocked on in between firewalls. iii. If interested in L2TP, make sure 1. Correct pre-shared key or machine certificate are present both on client and server. 2. L2TP port (UDP 1701) is not blocked on any of the firewalls. iv. If interested in IKEv2 based VPN tunnel, make sure 1. IKE port (UDP port 500, UDP port 4500) is not blocked. 2. Correct machine certificate for IKE are present both on client and server. v. If interested in SSTP, make sure correct machine certificate is installed on the server and correct trusted root certificate is installed on the client machine
where a TMG administrator has configured their TMG Server 2010 installed http://www.isaserver.org/blogs/shinder/news/l2tp-connections-fail-from-behind-a-nat-device-1165.html on a Windows Server 2008 R2 for inbound VPN connections. https://documentation.meraki.com/MX-Z/Client_VPN/Troubleshooting_Client_VPN External VPN users (two or more users) are behind a NAT device, which NATs all outbound L2TP VPN traffic. When users try to connect using L2TP VPN connections, only one user from this network can connect at a time. Every connection error 809 attempt from another user fails with the following error: Error message: error 809 The network connection between your computer and the VPN server could not be established because the remote server is not responding. This could be because one of the network devices (e.g., firewalls, NAT, Router etc.) between your computer the network connection and the remote server is not configured to allow VPN connections. Please contact your Administrator or your service provider to determine which device may be causing the problem.” Pretty interesting problem and one that definitely cries for a solution!
