Error 800 Vpn Vista
I have a public IP that is NAT to the adapter and the only firewall in between is the Windows Firewall with Advanced Security. I've created 2 rules, 1 to allow TCP 1723 and another to allow GRE but it still won't accept connections. What could the problem be? I can connect to the computer via RDP so it doesn't appear to be a TCP firewall issue and I can error 800 vpn windows xp also telnet 1723 from another computer on the Internet. Also, I have a SBS 2003 server that accepts VPN connections on another public IP address (in the same block) and that works fine. I've tried disabling the Firewall service altogether in Windows 7 Pro, but that seems to block all incoming connections.

The VPN server may be un-reachable, or security parameters may not be configured properly for this connection. You should doulbe check your firewall settings, pay attention to the profile step when you create the rule.(check all the options: domain, public and private) Another suggestion is to reset firewall to default, then add the rules for a test.

VPN Error 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 L2TP/IPsec tunnel, the http://www.cryer.co.uk/brian/windows/troubleshooting/w2k_error_800_unable_to_establish_vpn_connection.htm securityparameters required for IPsec negotiation might not be configured properly. or for Windows XP the error is: Error Connecting to VPN Error 800: Unable to establish the VPN connection. The VPN server https://www.experts-exchange.com/questions/28427572/VPN-Error-800-Connection-failed.html may be unreachable, or security parameters may not be configured properly for this connection. Where "VPN" is the DNS name of the server or the name of the VPN connection. Possible Causes error 800 and Remedies: Unfortunately Error 800 seems to be a general catch all error and does not give 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 error 800 vpn 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 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 forward

OS Version of machine that I'm assuming is running Routing and Remote Access services? 2. Are you accessing the VPN from outside the local subnet via the internet? If so, is there a firewall between your machine and the server? If so, have you created the appropriate NAT policies to allow the appropriate protocols through the firewall from the public IP address that would be the destination for the VPN clients, and the the server hosting the RRAS? 3.
