Virtual Private Network is a safe tunnel through the Internet, through which computer is connected with University network. The computer then has the same address as other computers at work. After turning on the VPN all traffic from home (or conference) is redirected to UW, and from there gets to the rest of the internet. You are working from your home, but your computer seems to be standing on your desk at work. To log in visit: vpn.uw.edu.pl
