The RZ recommends to not trust the eduoram network and to use a local firewall. This is due to several hundred different wireless devices, which connect to this network. If you use a Windows operating system, please select "public network" for the eduroam SSID. We recommend using the Windwos Firewall because there are no known issues with for example the VPN client.
You can find a summary as a flyer for printing at the WLAN entry page.
The subpages Information, SSID: VPN/WEB and SSID: eduroam give the interested reader even more background knowledge.back to WLAN entry page
Please make sure that your device has the latest patches installed, that you are not using more than one anti-virus program and that no "unblocker" is active.
(Unblocker are programs which can unlock content, that is blocked in one country, but not another.)
If you have questions or problems, please have a look at our help pages first. (Klick here for VPN Help)
