[plug] WAIX

[EricS]

Hi all
I have a query about Westnet WAIX traffic

traceoute mirror.pacific.net.au
traceroute to madheifer.pacific.net.au (61.8.0.17), 30 hops max, 38 byte
packets

10  madheifer.pacific.net.au (61.8.0.17)  96.160 ms  94.665 ms  97.041 ms

as this shows hop 5 on the way to the mirror is WAIX
How do I ensure the return path is via WAIX ?
It used to be, but for the last month or so it hasn't.
Any info on this will be appreciated.

Thanks
