Instructions for setting up remote access to systems available only from the PřF internal network (e.g. CIS).

What is a proxy server?

When using a proxy server, users' browsers read data from the network via a computer (proxy server) located at the faculty. The purpose of a proxy server is to allow its user to appear on the Internet as if he were connected from the faculty network.
 

Setup procedure

The setup procedure is slightly different for each browser type and version.

EZ Proxy can also be used to access only information resources ("scientific articles") of the faculty (without the need to set anything in the browser).

  5. Save settings [5]
  6. Switchy app! switch to Auto Switch Mode [6]
