Help! How can a router be detected by ISP?
I live in univerisity apartment and the school provide me with broadband internet access. But they do not allow private router usage which does not make sense at all. I hooked my router to the internet jack and after some time the jack was switched off by the school because my router was detected by the school somehow.
Can anyone explain this to me? And also, I want to know how to hide my router from being detected. It looks like my friend's router has not been detect so far. We are using different brand of router. Is that the reason or is there any setting in the router that I have to change?
Thanks in advance!

Ask the Admin you`ll probably find its because people using routers overload the line and this method also discourages the use of applications such P2P software

He has probably cloned the MAC address of his NIC into his router.
Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so. -Douglas Adams

Do you mean the P2P software really caused the problem?

If you need to have multiple computers accessing the internet at once and they dont allow routers, why not just add a second network card to your computer and hook up the second card to a switch. Then enable internet sharing and technically, you are not breaking any rules. No router and I can't see any way the school can detect the second card unless they notice a lot of traffic coming from your computer.

If I were to make an educated guess, the admin probably shutdown the port due to traffic and not necessarily because there's a router on it (even though it's against the rules). Also, if the admin is sniffing for packets that are encapsulated with a 192.x.x.x address, he'll probably shutdown the offending port.
As a rule of thumb, most admins tend to be lazy (yes, I'm generalizing), so he probably just noticed a lot of traffic on your segment and shut it down.

Probably right, detecting the NAT encapsulation.

other than NAT can only be detected from the internal network. To the external network its invisible.
so that leaves:
MAC registration, not using the MAC you told them you were
Traffic analysis (a bit to much bit torrent for you)
Router Misconfiguration (in linksys Gateway or Router. private addresses in side or public)

Agreed. I visit a government site regularly, and if I need to change any NIC on any device I have to inform the local I.T. before I do it or that part of the network gets automatically disabled if it detects anything other than it's pre-programmed MAC address. I forgot once, merry hell insued
