Does/did the gateway always have an ARP entry for _your_ IP?
Trying with something other than ping could be interesting. A netperf
UDP_RR test perhaps, or TCP_RR - although with the TCP_RR test, before
the requests and responses start to flow the SYN segments will have
been exchanged so those would be the "first" packets in the flow.
Still, if you ./configure --enable-histogram netperf you could try
that or a UDP_RR test:
netperf -t UDP_RR -H <remote> -v 2
and then look at the resulting histogram.
There could still be the issue of the control connection affecting the
initial packet behaviour though.
