Found out that MS Windows actually uses ICMP for traceroute, whereas
FreeBSD (et al) go with UDP. I've also turned off ipfw on one of the
FBSD boxes and I still can't even traceroute to the router!

So at the end.., I've resigned myself to emailing Zen on how they're
handling UDP ports 33434-33500 within their fabric.

I can't see anything else I can do here with respect to setting up the
FBSD boxes., if even with ipfw set to allow by default, I still can't
even traceroute the (Zen-purchased) router.

Regards,

Stacey
