If you do not need a full VPN, you can use a dynamic proxy via SSH to reach an internal computer from outside the Institute:
ssh -Dlocalhost:8888 username@login-stud.informatik.uni-bonn.de
(students) or ssh -Dlocalhost:8888 username@login-staff.informatik.uni-bonn.de (employees)
— replace „username“ with your user name.login-stud.informatik.uni-bonn.de
(students) or login-staff.informatik.uni-bonn.de
(employees)SSH
