Central firewall for institute networks


Administrators can set up their own network security zone for their institute networks in consultation with the network department of the HRZ.

For whom?


This service is intended exclusively for administrators.

What for?

Network security zone

    By setting up an institute's own network security zone, it is possible to control not only data traffic from the Internet, but also data traffic from facilities outside the institute on the university network.

    How does it work?

    For this purpose, a virtual firewall is set up at a central location. The activation is carried out by the network department upon request by the institute administrator(s).

    Set Up and Support

    Setting up an institution's own network security zone and the associated firewall requires intensive consultation with the network department to clarify the available options. Contact via netadmin@uni-bonn.de


    Detailed information and instructions can be found in the HRZ-Doku.
    (Call only possible from the BONNET)


    Currently by mail to netadmin@uni-bonn.de, where you can also get an excerpt of the current rules.

    There are two redundant firewalls that are operated at different locations.

    There are few UDP/TCP ports that have caused "problems" in the past that are blocked to the outside. These include protocols from the Windows file sharing area and SNMP. There is also a protocol check for few more ports.
