DHCP internet connection - HOT+BEZEQINT - Not getting IP

[Kfir Lavi]

Hi,
I have a very simple setup.
My router (Regular PC box) running DHCP client to get IP from the provider.
I don't need dialer for connecting.
This setup did work for the past half a year.
Two weeks ago in Friday night, my server stopped receiving IP address.
Running tcpdump shows a lot of traffice on the network of HOT. I see people
sending requests and getting dhcp replays.
I also see connections of bittorent that where active trying to reach my
computer.
After one hour fighting with HOT representative, she told me, hey you got an
IP.
Well, I did.
Now this Friday morning the same thing happened. No IP is offered to me.
I can see my computer sending requests, but no replays are sent to me.
I asked them to check that they get my requests, but they don't want to do
that.

Does someone knows why this can happen?
My guess is that they ran out of IP's, or there is a blocking software on
the DHCP server which blacks my MAC. (Oh, I didn't change my MAC address for
checking. I'll do it tonight. )
My download rate is 300kb, so its very low package, and and it doesn't seem
to be a bandwidth problem.

What is going there behind the seen with this DHCP server ?
Can it be my fault?
I have the white Motorola modem.

Today at night a representative of HOT should call me when I'm back home to
..... (CLOSE, RESTART... etc... "What ?!?! its not windows?? How come you
don't have start button?" well, what can you do.)

Thanks,
Kfir
