I have just checked the `/val/log/syslog` ( see also comment #8 ) and I have noticed that when the issue start I got this messages:
pppd[8268]: Protocol-Reject for unsupported protocol 'IP6 Header Compression' (0x4f) pppd[8268]: Protocol-Reject for unsupported protocol 0x1c18 pppd[8268]: Protocol-Reject for unsupported protocol 0xb9 pppd[8268]: Protocol-Reject for unsupported protocol 'RTP IPHC Full Header' (0x61) pppd[8268]: Protocol-Reject for unsupported protocol 'KNX Bridging Control Protocol' (0x8051) pppd[8268]: Protocol-Reject for unsupported protocol 'DECnet Phase IV' (0x27) A lot of them ( 3 every second ) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-pptp in Ubuntu. https://bugs.launchpad.net/bugs/290178 Title: pptp vpn connection drops out Status in “network-manager-pptp” package in Ubuntu: Confirmed Bug description: I use pptp vpn to connect to our office network. Under Hardy using Network Manager (NM 0.6.6) this worked very well and was stable. Under Intrepid NM0.7 the same connection is unstable. While it connects without a problem and i can initiate Remote Desktop Protocols etc... eventually the connection drops out with the error VPN connection failed. I can usually reconnect immediately, but not always, if not a restart is usually required. Reconnected VPN connectiions continue to be unstable and fail frequently thereafter. Interestingly, opening pidgin precipitates this connection failure (not sure about other applications).
