ISP ethics?

[JoelKatz]

They are still able to force a new IP onto your router.

Even if I set the router to static?

If this happened your computer would stop being able to use the internet. The ISP would reject your packets due to not owning the IP. This is the basis behind a DHCP based internet gateway.

The router will obey you but the ISP will not obey the router.

Unless you hacked the router, it wouldn't send any packets at all. It would never bring the IP link up because address negotiation had failed. Even if you did get it to accept packets, no packets bound for that address would ever get back to you.

Perhaps you are confusing the router with the modem.

There is no address negotation when static setups are used. Your router will send packets out on an IP that it is not assigned to if you set it up to do so, address negotiation is bypassed. You can hook your computer directly to your modem without a router and assume any IP, the router is just a hardware specific computer.

The modem on the other hand or the ISP gateway further down the line will filter these out.

You are of course correct that even if the ISP failed to filter the packets you sent out that your response would never make it back.

When ISPs were young and they did not filter so well you used to be able to spoof an IP and send a PING packet out to a thousand computers and they would all PING back to the IP you are spoofing. It was a way to hide your DOS attack, this of course does not work on the modern internet.

I'm tacitly assuming they're combined and that some link protocol (like PPPoA) is being used. The results are the same no matter what, but the details are different.

it broke several times and I powercycled until it completely broke. So I lost the battle lol

update: not broke just had to reset the router too often to consider a stable conection. So I chose stability over static.

static ip, helps me cause I use sip devices and remote pc's IE logmein etc, and if I have to powercycle I don't have to log in to everything again, and things register much faster.

The amount of fail and complete misinformation in this thread is incredible...

I'm responding on my mobile but my quick easy solution to this would be to setup a vpn.

If your using Logmein already they have a simple software vpn that I believe VoIP SIP will work over.  I forget the name for it but it used to be called hamachi and was free at one time, not sure if they charge now.
