Windows has a built-in L2TP client but by default Windows uses L2TP with IPsec. Don't worry, as Fourplex Static IP Tunneling can be made to work with Windows.

1. Open the Start menu
2. Open the Control Panel
3. Double click Network & Internet
4. Select VPN (link on left panel)
5. Add a VPN connection, with these details:
   • VPN Provider: built in
   • Connection Name: Fourplex
   • Server name: nyc.vpn.fourplex.net
   • Type: L2TP (With certificate) (Note: We will disable IPsec later)
   • Username: your username
   • Password: your password
6. Click Save

Enabling CHAP

CHAP authentication is recommended for Fourplex Static IP Tunneling. To do so:

1. Open Network and Sharing Center
2. Click Change adapter settings
3. Find the L2TP connection, it will have the provided name
4. Right click the connection and choose Properties
5. Go to the Security Tab
6. Find the Authentication section
7. Select the Allow these protocols radio button
8. Ensure Challenge Handshake Authentication Protocol (CHAP) is checked.

Disabling IPsec

IPsec is not used on Fourplex Static IP Tunnels for performance reasons, so it will need to be disabled.

1. Click on Start
2. Type Command Prompt and right click on it
3. Click Run as Administrator

When you are in the command prompt, enter the following:

SC STOP RASMAN
SC QUERY RASMAN
REG ADD HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Rasman\Parameters /v ProhibitIpSec /t REG_DWORD /d 1 /f
