[Bug 991666] Re: VPN Connects Successfully & Then Shortly Thereafter Fails
Hi, had the same problem with a pptp vpn (don't ask why we use pptp). As described i had to set the MTU of the physical network adapter (e.g. eth0) to 1000 to get the VPN working without disconnectes all the time. You can set the MTU easily via the network manager on the "ethernet" tab, but you have to restart the network stack before it gets activated (just diconnect and reconnect you normal network connection via network manager). You can find the current value of the MTU with ifconfig ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991666 Title: VPN Connects Successfully & Then Shortly Thereafter Fails To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager-pptp/+bug/991666/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi All, I have a good news to share, I could solve this problem after around a week. There are couple of points. # I have this problem, only with my Home Wifi. It was working fine with office Wifi / Smartphone Hotspot. # I could solve the problem by simply changing MTU value.

[Bug 991666] Re: VPN Connects Successfully & Then Shortly Thereafter Fails
I've had the same problem for about a year, and now, I think, I've finally found the way to fix it (at least somehow). Looks like in my case it was the same as in https://bugs.launchpad.net/ubuntu/+source/network- manager/+bug/991666/comments/16 (duplicate routes entries). So what I've done. - run `sudo route -n` before connecting to VPN and after - found entries that were pushed from the VPN server - found duplicate entry - manually added all but duplicate pushed entries to routes (Network connections -> your VPN connection -> IPv4 settings -> Routes -> Add ...) and checked "Ignore automatically obtained routes" checkbox. - restarted VPN connection Since that all works just fine.

[Bug 991666] Re: VPN Connects Successfully Then Shortly Thereafter Fails
Hi everybody, I have the exact same symptoms on 14.04 with a PPTP VPN. I have a very strong feeling this is related to custom routes. I can initiate the VPN and have it working (had it up for at least 15min without problems), but as soon as I add a custom route on the command line the connection drops after a couple of seconds. Also, when entered in the VPN/Settings gui, the connection drops shortly (seconds) after intiation. Is there some conflicting process which stumbles over the custom route? Perhaps dhclient or pptp itself? So, for now, VPN is unusable to me as I need a custom route.

[Bug 991666] Re: VPN Connects Successfully Then Shortly Thereafter Fails
This is a problem that I have experienced since Ubuntu 11.04 (I don't think I used a VPN with 10.10, can't remember). I posted here (post #9) in September 2011: http://ubuntuforums.org/showthread.php?t=1692353 I'm having the exact same problem with Ubuntu 12.04 - I can connect, the connection will stay up and work for a while, then it will disconnect at a seemingly random period (usually within a 10 minute timeframe). I'm having to use Windows 7 on the same computer (dual boot) to establish reliable PPTP VPN connections that stay up. This is one of the main reasons I can't ditch Windows completely. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991666 Title: VPN Connects Successfully Then Shortly Thereafter Fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/991666/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
