OpenVPN/TAP adapter problem on CentOS
 

I have installed OpenVPN server on a Linux box, and I configured it to use a tap adapter, this part is working fine. So far, I can connect my Windows box's OpenVPN client to this Linux OpenVPN server, but I cannot bridge the TAP adapter to eth0, because this loses the Linux server's connection to the network. There can only be one ethernet card in this server, so I cannot bridge the TAP adapter to another ethernet card and connect it to the same network. So, basically what I'm trying to accomplish is bridging the TAP adapter (tap0) to the only ethernet adapter (eth0) and not lose the server's connection to the network (eth0). I have searched Google for a solution, and couldn't find one. Please help! I am running CentOS with OpenVPN.

Thanks in advance,
