Hi
I have the following problem: I have established a working VPN connection to my University, but can't browse the internet:

I have managed to establish a working and browsable VPN connection on Windows XP, the attachments show the output of ipconfig and route print.
On my Linux machine, the output of ifconfig is:

What should I do to resemble the routing table from Windows on my Linux machine, that is, to get full connectivity on the VPN? It must be something with the routing table.
Problem solved: I inserted the statement "usepeerdns" into to peers file and made changes to the routing table:
iptables -A OUTPUT -p icmp -j ACCEPT
route del default gw 192.168.0.1
route add default gw 212.14.24.40 dev ppp0
Everything works fine now. |
