I am using NetworkManager with the pptp plugin to connect to my university VPN which uses MSCHAPv2 and MPPE. I have configured all of the settings identicaly to another laptop which runs Ubuntu and successfully connects but when I use my Arch install the VPN connects but there is no internet access. Instead a pptpgw process shoots up to >50% CPU usage. I ave attempted a fresh arch installation but it has not helped, neither has using pptpclient rather than NetworkManager.tcpdump -n -i ppp0Reveals a huge volume of outgoing compressed ppp data is being sent from my PC:16:40:57.223961 IP 192.168.0.11 > xxx.xxx.xxx.xxx: GREv1, call 52096, seq 410983, length 252: compressed PPP dataAny ideas on how I can troubleshoot the issue? I have looked through the wiki but to no avail, from what I have seen it may be a routing problem but I am unclear on how to proceed on this front. I have connected to this VPN previously from previous Arch installs and it has worked.
