Re: [Openvpn-users] Corrected version of "OpenVPN makes vpn-Server unreachable at iso/osi level if a client connects"

Hi OpenVPN Users,

[...]

Disclaimer:  I'm not a bridging expert I rout as much as possible.

In both configs:

dev tap0
- I think think this should be tap not tap0
- Then add "dev-node tap0"


dev tap0 is ok, on both sides. This tells you the animadverted comments in the config file:

# ... # On non-Windows systems, you can give
# an explicit unit number, such as tun0.
# ...

So its realy the problem? I tried... it also doesn't work if there is only "tap".

in fact wrong, what "tap0" is false... but in this situation a good hint, cause if
you enter "tap" the openvpn creates a new one, tap1, which isn't in the bridge.
So I found news about the problem: The problem doesn't occure as long as I
on't add the tap inferface on the server into the bridge (brctl addif br0 tap1)!
As long it isn't in the bridge I can ping the tap interface! If I add the interface
into bridge, it still works some seconds and then hangs. Anybody have a hint
about that? I think this looks like a linux kernel bridgeing problem?


Regards,
Markus Mueller
