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.
