Hi Dan,
Just to follow up on the same thread ([email protected]), I just
did a quick bash-script requesting the $ifconfig_netmask variable upon
connection. This is successfully set, in our case we're using a /24
subnet mask making $ifconfig_netmask result in 255.255.255.0 as
expected.
Hopefully I'll have some feedback from OpenVPN Technologies today
verifying the manual miss-print.

Hi!
To connect to an OpenVPN server that uses tun-devices with a non /
32 netmask one need this patch. I'm using NetworkManager under
Fedora 10 (same issues still exists in F11 alpha/rawhide).
So you're 100% sure that the server is configured to use tun mode,
and
that it's sending a netmask, right? The OpenVPN manpage indicates
that
'ifconfig_netmask' is only used with TAP mode. Is the manpage not
correct?
Jonathan (CC) has contacted OpenVPN folks to have this verified
directly from them.
The TUN interface has support for more features today,such as a non /
32 netmask and I would suspect the manual page is lagging.

The patch is the quick fix but the special treatment of tun/tap
relative network mask can be removed.
Question; will removing the tun /32 netmask hard coding cause
other issues.
