[nzlug] ADSL modem / dyndns

[SIMON WALKDEN]

The Dynalink RTA1335.

I've used these extensively and had no trouble (apart from at my
previous residence, however that turned out to be an issue with the
ASAM port it was connected to in the exchange).

Port forwarding, dyndns registration, it's perfect. and priced right too.
