I haven't attached a tcpdump output of the packets because a) the packets between machine A and B travel through a GRE tunnel and b) does anyone have tcpdump filters or know how to finagle tcpdump into dumping the embedded packet instead of the GRE header'd packet? If not, I'll supply tcpdump output of the traffic.
