VPN in the Munich Scientific Network (MWN)

What is VPN?

VPN stands for “virtual private network”. A VPN can be used to build a secure sub-network over an open, unprotected network (Internet, wireless network). Communication in this sub-network is protected against tapping and access by third-party participants. This is achieved by tunneling the data traffic via a VPN server using data encryption. Connections to this server have to be authenticated when set up.

VPN use in the Munich Scientific Network (MWN)

A VPN connection enables access to various MWN services. You have to establish a VPN connection if you wish to use the following services:

  • Access via the WLAN connections in the MWN that are managed by the LRZ
  • Use of public connection points for mobile computers in the MWN
  • Use of access-restricted, internal MWN services (examples: online journals of the Munich university libraries, remote update of Sophos anti-virus software) via third-party Internet providers or by inhabitants of student halls of residence

To use VPN connections, a username (campus.lmu.de, tum.de, lrz-vpn, RADIUS) and the installation of a client program are required. The VPN server cluster in the MWN supports two protocols:

  • SSL/DTLS (cluster address: https://asa-cluster.lrz.de) with the AnyConnect client
  • IPsec with XAUTH (cluster address: ipsec.lrz.de) with the IPsec client
