Hi OpenVPN Users,
In both configs:
dev tap0
- I think think this should be tap not tap0
- Then add "dev-node tap0"
Disclaimer: I'm not a bridging expert I rout as much as possible.
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?
I resolved the problem, but I don't realy why. I just avoided my switch
here in local lan, and it worked. The switch must have been affected the
remote LAN, so there is no communcation possible. Maybe the pcap
http://priv.de/dump4.pcap is usefull: One ping works, then I added the
interface to bridge and nothing works anymore. I only can see some
"Topology Changed" messages... could this be the cause for the problem?
Whatever... the problem is resolved, I'll replace the bad switch with a
new gigabit one.
Regards,
Markus Mueller
