My computer has IP 192.168.1.11, and sits behind a ADSL router which has 
IP 192.168.1.1, the router is the gateway to the internet. IP adresses are 
assigned by DHCP. The vpn network of the university I would like to 
connect to has the adress vpn-eur-pptp.eur.nl. The IP range of the 
university is 130.115.x.x.

My ifconfig and netstat when mpd5 is not running:
