Can anyone explain, or even guess, why the difference between ex-tunnel
and in-tunnel ping times is so much more when the link is ADSL to PSTN -v-
ADSL to ADSL. I know why the base latency is greater, but that doesn't
explain the difference in latencies. All machines at the gateways are
comparable (typically mid-range Celerons).
ADSL to ADSL (3 cases) ex-tunnel=65msec in-tunnel=80msec diff=15msec
ADSL to PSTN (1 case) " 185 " 235 " 50
ADSL to PSTN (1 case) " 345 " 490 " 145
