[Bug 480719] Re: OpenVPN connects but no access to remote network and then connection fails

[Mathieu Trudel]

Hi,

I see a number of issues with the APIC on CPU0. This is likely not
related, but you may want to open a new bug about it (and try to see if
your system boots with the noapic kernel option).

Also, please make sure that the openvpn configuration you are using is correct: 
Nov 11 10:20:17 tatooine nm-openvpn[20271]: Bad LZO decompression header byte: 0
Nov 11 10:20:58 tatooine nm-openvpn[20271]: LZO compression initialized
These messages indicate that you have probably enabled LZO compression in the config, but that it is not enabled on the server. You should see if the connection stays established with compression disabled.

Additionally, these errors indicate similar issues:
Nov 11 10:21:14 tatooine nm-openvpn[20271]: WARNING: 'link-mtu' is used inconsistently, local='link-mtu 1542', remote='link-mtu 1546'
Nov 11 10:21:14 tatooine nm-openvpn[20271]: WARNING: 'mtu-dynamic' is present in remote config but missing in local config, remote='mtu-dynamic'
In both of these cases, you should try to set the mtu options to match the server's, as they should help with connection performance.

Please let us know whether these changes improve your connection
stability.

Thanks for filing a bug and helping to make Ubuntu better!
