I have been working with tap interfaces, bridging and openvpn Bridging works perfectly, and openvpn does too Packet pings from the tap interface works to any ip address, on the local machine or computer on the bridged network Attempting to make a tcp connection works for bridged network, but not the machine the tap interface is on I have found this is due to tcp checksums not being generated, Packets recieved over the tap interface on the client machine have blank (bad) checksums. I have looked at the source and it seems there is no interface to add the checksums to be generated for the tap interface.
