15 15  **Please note**: A connection to the VPN can only be established from **outside** the respective chair network (for example the networks which are configured in the VPN). On the one hand, since a connection would create double routes, and the VPN usually uses a UDP connection and UDP is completely blocked in most networks.

17 17  The VPN does not allow a direct connection to the Internet. Under Windows, access to the Internet should be possible via the direct network connection of the computer; under Linux, either the web proxy (proxy.in.tum.de) can be used or the routing table must be set so that the VPN is only used for routes provided by the VPN (no default route to the VPN).
