Setup a Bridge using SLIP/PPP and Ethernet connection

Hey

We need to bridge a regular ethernet connection with a Serial Line IP
(SLIP)... is this possible/howto

We are using the program slattach to setup the point to point connection
(SLIP). However when we setup the bridge using "brctl" it requires raw
interfaces without any IP assigned.

Is it possible to get around this somehow?

I'm open to other SW solutions but the hardware is a WLAN-card and a
0-modem (seriel connection).

Direct transfer of Ethernet frames into a point-to-point
connection is a no-go, but you can tunnel the frames
with a VPN.

If you have to move the Ethernet frames via the serial
link, OpenVPN could be a solution. In this case, you
could set up a bridged OpenVPN (using tap0) connection
without encryption.

You can send ethernet packets via GRE, but I seriously doubt you'd want to
bridge an ethernet network to a serial line.
