-===Internet Access===+ ===Internet Access===
  
-Internet access will be available by using our VPN. To get a vpn account please follow the [[en:vpn:linux|VPN installation guide]]. +Internet access outside of the Institut of Informatics or the B-IT is not provided currently.
-==VPNC==+
  
-The vpn client required to access our network is already preinstalled. Open the commandline and enter the following commands to start a VPN connection:+For WWW downloads etc. you can use our web-proxy at ''**web-proxy.cs.uni-bonn.de**'', protocol **TCP**, port ''**3128**''.
  
- <code>~$ sudo vpnc 
-[sudo] password for ptw: enterYourAccountPassword 
  
- Enter username for 131.220.242.5: enterYourUserName 
- 
- Enter password for ptw@131.220.242.5: enterYourVPNPassword 
- 
- VPNC started in background (pid: 1337)</code> 
- 
-To verify that your VPN connection is up and running: 
- 
- 
-<code> 
-~$ ifconfig -a 
-tun0     Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

-==Static Routes== 
- 
->Important: Please consider the notes below about the network connectivity of your PVM. 
-> 
->Once your VPN connection is up and running you may experience loss of connectivity to your VM. This occurs because the main IP Address will change to the VPN Address. 
- 
-To avoid a loss of connectivity we preconfigured static routes in: 
- 
-/etc/network/interfaces 
-<code>... 
-  up route add -net 131.220.4.0/24   gw 10.5.5.1 dev eth0 
-  up route add -net 131.220.5.0/24   gw 10.5.5.1 dev eth0 
-  up route add -net 131.220.8.0/24   gw 10.5.5.1 dev eth0 
-  up route add -net 131.220.240.0/24 gw 10.5.5.1 dev eth0 
-  up route add -net 131.220.152.0/24  gw 10.5.5.1 dev eth0  
-  up route add -net 131.220.155.0/24  gw 10.5.5.1 dev eth0</code> 
-   
-If you access your PVM from one of those subnets your network traffic will be routed directly and not via VPN, so that you may safely enable or disable your VPN without loosing current network connections to your PVM.
