Title:
VPN Connects Successfully & Then Shortly Thereafter Fails
Status in “network-manager-applet” package in Ubuntu:
Confirmed
Bug description:
I am able to successfully establish a PPTP VPN connection in Ubuntu
12.04 (kernel 3.2.0-24-generic) but after approximately 30 seconds to
1.5 minutes it will fail. During the connection time I am only able
to load about 1-2 webpages and then they freeze and I cannot access
resources on the VPN network. I do not believe this is related to my
VPN server as I am able to establish VPN connections with my Windows
machines and Smartphones all day long with no problems. Is there a
solution to this problem?
Description: Ubuntu 12.04 LTS
Release: 12.04
network-manager: 0.9.4.0-0ubuntu3
