+ | |||
+ | Recently, some people working from home have been reporting problems when trying to connect to Sterrewacht (or even all Leiden Universtity) computers, especially people renting apartments with DUWO. There is likely a problem with the DNS (domain name server) of the local internet provider. To bypass this problem, Sterrewacht users can activate the STRW VPN. For this to work, users with an existing VPN client (.ovpn) file need to make a small change. From the OpenVPN program or app, select to edit the configuration file. In the editor that appears, replace the text '' | ||

+ | The provided VPN client file redirects all internet traffic over the Observatory VPN. There are however situations in which it is unnecessary or even discouraged to tunnel a connection via our VPN. Imagine, for instance, how inefficient it is to tunnel a videoconference through a VPN tunnel. | ||
