Bridged openVPN server on Mac?

[Kosh]

I successfully installed an openVPN server on my Mac OSX Snow Leopard.

It starts automatically and I also can connect to the VPN Server from the internet from my MacBook via Tunnelblick.

But:

I configured the server to be a "routed" openVPN server.

So the VPN client can only reach the server and not the rest of my home network,

even if i push a route to the client.

Now I want to change the server from "routed" to "ethernet bridging"

Thats where the problems start.

There is no HOWTO on openvpn.net for ethernet bridging under Mac OS X, and the howto for Linux does not really work because there are no Tun/Tap interfaces shown in "ifconfig" although the Tun/Tap driver loads successfully.

Do you have some advice how to set up this correctly?
