Incidentally - I just experience a similar issue:
Internet is via "Kabel Deutschland" - that is: via the TV cable (not DSL)
There is a router which makes the IP given by the provider accessible to many computers via NAT.
- one of the users wanted to use "rapidshare" to download something
They have a free service which allows one download (with reduced speed) every so many minutes without being registered or paying.
This sevice is also bound to the IP - if someone else from that IP was already using the service - noone else could until the timeout ...ahhm ...timed out
(sorry - struggling with english)
The issue:
- noone on this LAN was using that service (I'm certain!) - so: no timeout or denial to use the service should occur
-
but it did! - and it still does at this moment
One reason I can think of is:
- they are using the 91.65.0.0/16 subnet, so ca. 65.000 IP's are available
- they surely have more customers than that - so what will happen is probably them putting 2 or more users on one IP - NAT again just as with the home-router
...and the other one, whom I don't know, is using the service already?
Am I completely wrong?
Here a router reset would probably help - have to test.
[edit]: in light of the next post - probably not
Would need to try to reset the "modem" or whatever it is, which comes before/in front of the router, but this can't be done remotely.
I can log into the router, but the modem is not accessible (not for me - it
is for service technicians).
