IT Freedom's Virtual Private Network (VPN) service allows you to securely connect to your office network from nearly any remote broadband Internet connection, such as your home network, to access files, printers and other shared network resources as well as your office computer. We use the open-source product OpenVPN as our standard VPN server solution.

Problems Connecting to Your VPN

If you're having problems connecting to your VPN, you may have one of the following issues: 

Incorrect Username or Password

If you enter an incorrect username and/or password when prompted by Viscosity, you'll receive an Authentication Failed error box. If that happens, click OK and then start the connection process over again. Make sure you're using the correct formatting for the username; if you're not sure, please contact the Helpdesk.

Firewall Settings on Your Internet Connection

VPN data travels through the Internet on an assigned channel (known as a port). On rare occasions we'll encounter a network that will not permit traffic on the VPN port to reach client computers. If you suspect this might be happening to you please contact the Helpdesk.
