Remote access (proxy settings)

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

For access to only the faculty's information resources ("scientific articles"), you can also use EZ Proxy (without the need to configure anything in the browser). However, by following this guide, you will also be able to access all the faculty's information resources.

What is a proxy server?

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

Setup Instructions

For access to only the faculty's information resources ("scientific articles"), you can also use EZ Proxy (without the need to configure anything in the browser). However, by following this guide, you will also be able to access all the faculty's information resources.

Google Chrome

The recommended setup is through the extension FoxyProxy. This extension replaces the previous, now unsupported, extension SwitchySharp.

The FoxyProxy extension allows you to easily switch between proxy and direct connection either automatically or manually, which is often very useful.

6. In the top menu, click Import, then expand the Import from older versions option and click the Import button
   
   
7. Upload the "FoxyProxy_natur.json" file from step 1
8. Check if the proxy cache.natur.cuni.cz has been added and click Save
   
   
9. Clicking left-click on the FoxyProxy icon, set the mode to Proxy by Patterns – for CIS access, the faculty proxy will be automatically used, otherwise, it is turned off
   
   
10. You can quickly toggle between proxy states by clicking left on the FoxyProxy icon
