any indication as to why it failed. The following list of things to check may therefore be incomplete: Double check the address of the server. Check that there is a valid network connection between your pc and the server. The simple way of doing this is to run ping at the command prompt: ping vpn-server Replace "vpn-server" with the address of the vpn server. Unfortunately an increasing number of firewalls block ping, so error 800 vpn vista a positive result indicates that you are taking to the vpn server, but a negative result does not necessarily mean there is no network connectivity. Check that port 1723 is open on the firewall. The easiest way be to use cryping, which allows a ping link connection to be made to the port: cryping -p 1723 vpn-server Replace "vpn-server" with the address of the vpn server. This will show a successful connection, indicating that port 1723 is open and something listening or that either the port is closed or that nothing is listening. If you get no response on port 1723 then either that port is being blocked by a firewall or there is no vpn server listening. You will need to establish which. Other things to try if the above does not help, but which I've no first hand experience of, include: Check that the firewall is forwarding IP Protocol 47 (GRE - not to be confused with IP port 47). However, if GRE is not forwarded then you would probably receive a different error. Ensure that the router (or firewall) protecting the VPN server support VPN connections. Check with the manufacturer's website to see if a firmware update is required. Its generally good practice to ensure that your router (or firewall) is running with the

[This can be set by clicking the ‘Network Connections’ icon on the bottom right of the task bar, Select your Connection, Right Click -> Properties -> 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 fa
800 The remote connection was not made because the attempted VPN tunnels failed. The VPN server might be unreachable. If this connection is attempting to use an L2TP/IPsec tunnel, the security parameters required for IPsec negotiation might not be configured properly Error 800 is often caused by GRE not being forwarded or processed. GRE is protocol 47. GRE needs to be forwarded, or the firewall needs to be PPTP- or VPN-aware (often called "VPN passthru" or "PPTP passthru" in firewall settings). Port 1723 is done to exchange some basic parameters for the connection (the "control channel"), but GRE is the protocol used to transfer the encrypted data. So if only PPTP (port 1723) is working, you get stuck in-midst of the "registering" or "login" phase. Make sure that port 1723 is properly forwarded and the firewall on the router is not blocking any connections to the VPN Server. You also need to ensure that your router allows GRE 47. Some routers do not support the GRE protocol, if that is the case then you need to replace your router with the one that allows GRE 47. error 800 vpn error code 800 vpn connection error 800 vpn error 800 vpn error code 800 2015-04-05 Kevin Arrows Share Facebook Twitter Google + LinkedIn RECOMMENDED: Click here to fix Windows errors and optimize system performance About Kevin Arrows Hi!
