Die Grundregeln ohne einzelne Sonderregeln sehen folgendermaßen aus:
- Lehrstuhl-Netz (1): Dürfen sich überall hin verbinden, bieten aber keine Dienste an.
- System-Netz (2): Bietet Dienste nach innen an.
- Server-Netz (3): Bietet Dienste nach außen an.
Auf einem Server ist normalerweise keine lokale Firewall installiert. Das Netz wird durch die uniweite Firewall des RZs/ITS jetzt HIZ-Saarland geschützt.

Access
VPN
Official page at HIZ HIZ anyconnect von Cisco
If you don't need the „official“ Cisco AnyConnect VPN software, I highly recommend installing the „network-manager-openconnect-gnome“ package in the Ubuntu Repository. It uses OpenConnect which is an open source client for AnyConnect. Anyhow, that package allows for you to configure and manager your AnyConnect VPN connections through the normal network manager.
I have been using that to connect to my work VPN for the past few months and it has been working great!
You can find the package in the Ubuntu Software Center or Synaptic by searching for „OpenConnect.“
If you wish to install it via the command-line, you can do so with:
sudo:
apt-get install network-manager-openconnect-gnome
I use this too in place of the cisco software, but it's really just a workaround. My University is doing an update of cisco this week and I'm a little antsy it will break the compatability
This solution did not work for me on 64-bit Ubuntu 14.04. It did not offer the UI needed to connect, I missed e.g. an option to enter group and user name and password.
It worked, but feel it's missing half of the explanation. This adds (at least on Linux Mint) an option to Network Connections. When you choose to add a connection, there'll be a new option to add a „Cisco AnyConnect Compatible VPN (openconnect)“. You can then connect to the VPN through the networks applet (in the system tray). This seems the ideal place for it.
Super User should do this:
apt-get install network-manager-pptp apt-get install network-manager-vpnc apt-get install network-manager-openvpn
If prompted for your password, type it, and press Enter.
If you're told that a package “is already the newest version,” ignore it and continue with the next command.
If asked to “continue [Y/n],” press Y, followed by Enter. then:
Modify connection to cisco with your userid and password from University here.
