It's just an ethernet frame with an extra field filled in AIUI I did do dumps earlier, and the problem seemed to be around about the bridge device at the far end as I pinged, however I will start again from scratch tomorrow and get some data. I was on a bit of a mission today as I need to have a working solution soon, so I tried combinations of OS and tunnel techs. The only actual success I have had so far is Linux with OpenVPN in tap mode. Anyway, thanks for your help so far and I shall return. Cheers, Dunc
