Cool, didn't know that. Works for me too. Funny thing is, the firewall
has

Destination     Gateway         Genmask         
0.0.0.0         203.79.122.1    0.0.0.0         

and therefore theoretically, the packets to 192.168.100.1 should go to
Telstra's gateway. I conclude the modem is intercepting them although
they aren't addressed to it, and that's the only reason one can talk
with the modem. The modem still does not have an addressable interface,
there's no MAC address or arp listing for it. The arp table contains a
MAC address for Telstra's gateway, but not for the modem.

> Port 80 on the modem is open too.

Not much else than 80 though. As one would expect.

> Have a look, it's quite interesting.

Indeed!

Yeah, and which stopped working a day after...  hmm. Ok. Never mind.

VxWorks is the most common real-time OS for embedded systems. The
company, Wind River Systems, is rather caustic towards Linux (perhaps
because they don't get royalties? hihiii).

"dumb cable/ethernet bridge" is a technical term for one of exactly those
modems, I understand. "dumb terminals" are also a lot brighter than what
you're suggesting. (especially when you turn the lights off :) )

Ack. Does seem to exist though:  "Enable DHCP Server  The SURFboard
cable modem can be used as a gateway to the Internet by a maximum of 32
users on a Local Area Network (LAN). When the Cable Modem is
disconnected from the Internet, users on the LAN can be dynamically
assigned IP Addresses by the Cable Modem DHCP Server. ..."
