VPN error 412 Possible solutionsTo fix the problem, try the following:
- If you are using wireless, try to connect with cable.
- Turn your firewall off, then test the connection to see whether the problem still occurs. If it doesn’t then you can turn your firewall back on, add exception rules for port 500, port 4500 and the ESP protocol in your firewall.
- Turn on NAT-T/TCP in your profile, and unblock port 10000 in your firewall.
- Edit your profile with your editor and change ForceKeepAlive=0 to 1
- Configure your firewall to permit UDP ports 500 and 62515. These are required for Cisco VPN client.
- Verify that your client is actually transmitting packets: Start a command window and run the command “netstat -s -p ip 60″ to see IP send and receive packet counts.
De firewall is uitgeschakeld dus dat is het niet, ik heb zelfs de AVG virusscanner even uitgezet maar dat hielp ook niet.
Wat bedoelen ze met deze twee 'oplossingen'??
