All other traffic will go through your existing internet connection. • The VPN Client includes an integrated firewall to protect the VPN Client PC from internet attacks while connected. • If your PC is protected by a firewall (Kerio, ZoneAlarm etc) you may need to adjust it’s settings to allow the VPN Client to communicate with the campus VPN server. How this is accomplished will depend on the firewall you have installed. • If you have questions, or require assistance, please contact the ITS Help Desk (966-4817)
