Bridging and OpenVPN

Hi,

while installing OpenVPN to integrate a remote client into a LAN some
questions came up:

The remote client should get a LAN IP. But even when I set an explicit
route to the remote client over the TAP device and enter ARP entries
manually, routing does not function properly. Has just something gone
wrong or will this a priori not work? Why does it work with a ppp
device?

I tried to set up a bridge to link the TAP device to eth0, but
apparently eth0 does not work any longer when it is part of a bridge.
Correct?

Regards,
André

You have to ifconfig eth0 down; ifconfig eth0 up 0.0.0.0; ifconfig tap0
down; ifconfig tap0 up 0.0.0.0; brctl addbr br0; btcrl addif eth0; brctl
addif tap0; ifconfig br0 up the.ip.you.want
