I didn't say I "bought" it. And I didn't say I wasn't going to to tell 
you why, just not NOW. Stop putting words in my mouth. I already have a 
wife. <bg>

As Ethan Hunt says in MI, "It's much worse than that."

Actually, there are two reasons...

First, remember the scene in Cheers where Sam is making mistakes 
ordering things, and one day, a delivery guy drops off a stack of 2x4s, 
a dozen bags of concrete, and a wheelbarrow? Woody bids the guy goodbye 
after the requisite spirited exchange, then closes the door, looks at 
all this stuff in the middle of the bar floor, and says, "Well, now.... 
the only question left is... what am I going to build?????"

Same thing here - I have a line. What might I do with it?

Second, I didn't want to predispose the answers. It's a long held truth 
that in survey taking, you first ask, "Tell us everything you liked 
about X." followed by "Tell us everything you disliked about X." Instead 
of "Please rate the following nine items on a scale of 1 to 5." If you 
provide stock answers, you automatically narrow down the answers you're 
going to get, without necessarily meaning to.

So instead of leading people to the answers I wanted them to provide, I 
wanted a wide open field.

Third, I do not know. I might use this as a spare access line in the 
event that the T1 goes down. I might use it as my main access line, 
ridding the T1 when contract time comes up. I might use it as a test 
line. I might move my T1 hosting to this line. I might decide it's a 
piece o' crap and get rid of it. I do not know. I was looking for a 
variety of possibilities. :)

So there are my two reasons. <s>

It's grey. Does that help?

Well, actually, it's a dark grey. Almost a dull black.

Shiny on the front, too.

Seriously, the box has NO markings, numbers, any ID whatsoever on it. 
It's small, grey, has six holes on the back (power, 4xEth, USB). Four 
stickers on the bottom that say "Cable RF Mac Add 20957297348" and a 
fifth that says that Time Warner will throw me in jail and pull out my 
fingernails if I even think about screwing with the box.

Hence my confusion.

And I like my fingernails.

Then they're not actually 'tech support', right? I did have to give them 
my account number, and they were able to tell me what my reverse DNS 
was. I'm expecting that they should know what they delivered to me, else 
what support are they going to be able to provide. Refer to previous 
email re MSFT vs Leafe tech support. <bg>

Well, cuz that's what I ordered, and I done went ahead and believed 
them. The bastards! Oh, I feel like such a foole!

Oh, I also plugged a machine in, popped in my static IPs (below), and 
verified that all four do get out to the Web, and report back via 
www.myipaddress.com. I have a Web server on one of the IPs, and can 
http:/1.2.3.4 to the server from 1.2.3.5 successfully.

I have a block of 4 IPs, 1.2.3.4 through 1.2.3.7. (I think that's four, 
right?) I lack the self-confidence that many of you have in trusting 
your HCPs to Mr. Dynamic, and so always statically assign IPs to boxen. 
So I entered 1.2.3.4 into my static IP for a test box. 
www.myipaddress.com says I'm on 1.2.3.4. If I do that for 1.2.3.7, I get 
a similar, warm and fuzzy response.

So I that's why I think I'm just getting access to the outside, and my 
PC needs to provide a firewall - or I need to do 'something else'.

OK, I took another machine down there and hooked it in on a second of 
the four ports in the back. And a third and a fourth. It looks like all 
four ports 'work' - i.e. I can connect a machine to the Internet via any 
of the four, and at least two of the four work at any given time.

I don't think the little grey box has any intelligence in it, though.

Guess this is one of those "dog looks like the owner" situations, except 
with Internet connectivity appliances.

Oh, the usual. Online gambling on one IP. Girls, girls, girls, all 
nekkid, all the time, on another. MMMP DOOM 5, 24/7/365 on a third. And 
the fourth? Well, that would be a spare. I was considering writing a 
replacement for google or amazon, but the holidays are coming up and I'm 
pretty busy...

OK, you got me. "I don't know."

1. I could.... have four boxes hooked up to the four Eth ports on this 
modem, and set all four boxes up with their own firewalls.

The big thing, as I sort through this, is that I don't want to set up 
four firewalls for four different IPs. That doesn't seem very 
'reusable'. Doesn't scale well, either.

2. I could ignore three of the Eth ports, plug a firewall into the 
fourth, and then plug the other end of the firewall into a 
router/switch/hub/xmas tree, and then hook my four PCs into 
aforementioned router/switch/hub. I could go past four PCs if I wanted 
to NAT on one of the four static IPs, of course, like I do with my T1 now.

Remember I'm a mechanical engineer - the EE profs pushed me out the door 
damn-damn quick, doncha know. So the magic that happens inside - like 
Vegas - stays inside. I'm just looking at wires coming out of boxes.

Conclusion: I think Door #2 is where I'm headed, but I'm still open to 
other ideas.
