thanks for that Dale,

in the security environment I'm envisaging defelection of random
portscanners (as provided by NAT) is probably going to be sufficient.

while i'd love to build a little micro ITX box, the cost is leaning me
towards one of these commodity boxen.

| G'day guys.
| My house (share with two others) has been signed up for TransACT and I'm
| looking at my options for a cable/router.
| I've had solid service from the netgear rt314 in other places but on
| cougar i see they're selling the linksys "EtherFast Cable/DSL Router
| with 4-Port 10/100 Switch" (LIN-BEFSR41) for $170
| As opposed to $377 for the netgear model.
| Does anyopne have any experience of the linksys model with TransACT?
| AnandTech seemed to rate it reasonably well:
| TIA,
| John
