Forms for Activating Workstation PCs and Procedures
You can find the forms here, where you can enter the IP addresses of workstation PCs for which you need firewall access. These workstation PCs will then require a static IP address. We classify such devices as servers.
However, workstation PCs cannot be added “on demand”!
Due to the associated security risk, authorization always requires the signature of the facility director.
If you have any questions, please send an email to: Network Infrastructure Department.
