HI all,
Another suggestion I'd like to make is to have the ability to use a
OpenVPN config file (ie. the GUI would allow you to specify a config
file).
Assuming it will take some effort to create a GUI for all the possible
OpenVPN options, it would be very helpful if network-manager-openvpn

Thanks for providing the patch - hopefully it will be accepted upstream for
10.04LTS.
I've installed it manually using the instructions you provided and installed
the updated network-manager-openvpn package.
Unfortunately it doesn't work (I checked Use custom fragment size (1300) and

I'll refrain from commenting on what you quoted. However, I'll
reiterate that now is good time to prod upstream to make the commit. :)

Hello Mathieu,
the options i added are merely arguments for the openvpn client

those options (it's on the openvpn wishlist, tho). while it seems

Magnus,
Thanks for the patch! Unfortunately, this issue is still being discussed
upstream (see https://bugzilla.gnome.org/show_bug.cgi?id=603575). I'd go
on that aspect with the reporter for that bug and say that the best in
all cases is to calculate an MTU (and MSS) from the route to the

Interestingly, my first glance at the code of the Cisco VPN client for
Linux seems to indicate that it would always default at using a MTU of
1300, since it needs to account for the worst case scenario of IP, UDP,

Why is this a wishlist item? At least for network-manager-pptp, this
seems to be a regression from hardy, i.e. the GUI configuration dialog
under hardy provided the option of setting a custom MTU for PPTP
connections. (The fact that this setting was subsequently ignored is a
different issue, namely

Why did you mark this bug as invalid? OpenVPN offers those

Because it doesn't include the possibility to set such parameters.
OpenVPN itself already allows setting such values by manually editing
the configuration file. The problem here is that the NM plug-in for
OpenVPN doesn't even support half of the parameters that OpenVPN
itself offers.

Finding a generic solution would be ideal, but given how both VPN back-

ways, I don't see how this could be done. Besides, I was only talking
