Hi,

I change the architecture this morning (before, the OVPN server
was inside the LAN and I used only one ethernet address).
Here is what I try to do :

           windows XP pro SP1
     OpenVPN client (192.168.1.x)         other stations
             |       (DHCP)                 | (don't use VPN)
         LAN |-------------------------------
             |
          firewall (fixed public IP)
             |
          INTERNET
             |
             |       DMZ     (192.168.34.6, fixed IP)
          firewall--------------OpenVPN server
(fixed       |                       | (192.168.35.x, DHCP)
public IP)   |                       |
             |  LAN (192.168.35.0)   |
           ---------------------------------------
                  |                              |
                  |                              |
               Windows NT                   other stations and servers
                share
            (192.168.35.2)
              (fixed IP)


I want the OVPN client to access the windows NT share.
In the OVPN documentation, I read that to exchange NETBIOS broadcast 
beetween a client and a server I have to use a bridged IP tunnel, not a 
routed IP tunnel.
I read the ethernet bridge howto and adapt it to an OBSD configuration.
(the bridge-start script).

Am I wrong ?

Thanks.
