Point your Web browser to your IPCop firewall.
Click on the left hand margin menu button labeled VPN
Login using the user ID “admin” and your administrator password. At this point, you should be looking at the VPN administration web page. In most circumstances, the global settings should be left blank and unchecked. If you have not created any VPNs, the manual control and status section should be empty as well.
Click on the tab labeled connections at the top of the VPN administration page.
Fill in the values for the connection name and the left and right hand networks.
Fill in the secret field from the generated secret pass phrase.
At this point, all the data you entered should be visible in the current connections section of the page. Verify that you entered all data correctly and then repeat the above steps on the other end of the VPN. Once both ends of the VPN have been filled with identical data, activate the connections:
Click the tab labeled control at the top of the VPN administration page.
Click the restart button.
