Hi Francis, Are there instructions for strace'ing the server process? Even so, would that tell us anything that would help us find a solution? It is perplexing that we have gotten this working over tuntap interfaces in other application contexts but can't seem to get it working in this one.
Also, see attached for the packets in pcap form suitable for wireshark. The packets appear to be formed properly.
