Agreed. :)

I also read an article about how lack of consumer knowledge of routers/bridges contributed to the naming of "cable modems". Modems are what was familiar at the time.


So why is it the cable company get's upset if I put my own router between the cable modem and my computer? My guess is, I've just "blinded" them. Hehe.. and they don't know if I have 1 or a dozen computers on that one connection because they charge by the number of devices, not the bandwith used.

There was a time that the value of a publicly routed IP address prompted fees for the use of multiple addresses. Now their value is so high that most providers would prefer the use of a device that hides all your equipment behind 1 IP. Comcast alone has around 17 million Internet subscribers. With the rush on remaining IPv4 addresses, adoption of IPv6 and related 6-to-4 transition mechanisms is gaining traction.

Speaking of IPv6, will TWGS accept connections on IPv6 addresses?

Not immediately. I currently have no way to test, so I can't implement support until testing becomes more practical. But I intend to do it. There will be cosmetic issues to deal with the new addressing. Other than that, I think a lot of the details will be abstracted from the app level.

I wonder how readily IPv6 could be adopted by players, as many of the helper programs will not likely know how to connect to an IPv6 host at this point.

Yeah, but the Swath guys (and some others) always seem to be lurking, ready to make some changes and put out a new version when TWGS is updated.

They don't care until uneducated people start calling blaming the cable modem for internet issues and it is really a faulty router that the end user installed. Plus most ISP's are providing a pipe size and since you can't exceed it thene it doesn't matter.
If your paying for 1.5M pipe, just because you have 10 computer you are not pulling 10*1.5M = 15M .... your still only getting 1.5M split between 10. No one that I know charges per connection.

They used to bill $5 per extra IP. NAT fixes that, tho. NAT makes IPv4 still viable.

That only happened if your were using a switch if memory serves me correctly. Once everyone started using routers it handed out the IP's behind it and basically hid the rest from the Cable Modem.

Right, that's a NAT. But you can run router w/o it and have the ISP dish out DHCP addresses if you want, you don't need a switch/hub to get multiple routable addresses. You could even roll your own router if you wanted to manually switch traffic to along different IP and interfaces (not sure why a home user would want to, but would be nice for big QoS stuff).

But yeh, by default, most people just use the nat/pat that comes with their router. There really isn't much sense in paying for multiple separate IP dynamic addresses.

Actually a neighbor of mine is a bit OCD and got on the kick of downloading movies for his home theatre. Cable told him he was at his limit. We never knew we had a limit to the amount of stuff we could download.

And yes, here Charter wants to know how many computers you have connected so they can charge you more.

I actually had a client whose ISP required you to go to a web page and activate the computer. We called them to find out why the router wouldn't work and they didn't allow routers. We ended up activating it on one PC, and then spoofing that MAC address on the router.

also, SBC provides a DSL modem with a built in router. Only 5 devices are allowed to connect though.
