[Openvpn-users] trouble with OpenBSD, OpenVPN and bridge mode

[jyblst <jyblst@xxxxxxxxx>]

Hello,

I'm using OpenVPN 1.6 with OpenBSD 3.6, on a Soekris 4801 target.

I configured OpenVPN in the bridge mode, with TCP on port 50.
OBSD is running the server.
The client is a Windows XP pro SP1 with OpenVPN 1.6 too.
Bridge is configured on the client.

I can't ping or access any host on the remote lan from the client.
I could ping eachover when I tried OpenVPN with the routing mode.

It's the first time I use bridge on OBSD.
Before launching OpenVPN, I run :

ifconfig tun0 link0
ifconfig bridge0 create
brconfig bridge0 add sis0
brconfig bridge0 add tun0
brconfig bridge0 up

No problem.

Then, I run OpenVPN with the following config file :

port 50
verb 11
proto tcp-server
dev tun0
#dev-type tap
#secret /etc/openvpn/shared_key
#comp-lzo
#ping 10

And, on the client :
port 50
verb 11
proto tcp-client
remote x.x.x.x
dev tap0
ifconfig 10.1.0.2 255.255.255.0
ifconfig no-warn
#secret shared_key
#comp-lzo
#ping 10

I tried also with an OBSD client, also tried different OpenVPN  options.
Same problem.
Log example, from the server (problem with select() ?) :

Any idea ?

Thanks,
J-Yves
