Hi, I'm trying to set up a Video Surveillance system on an XP Pro machine
connected to my motorola surfboard sb5101 cable modem through Telenet.be in
Belgium. It can be set to use any port, but uses port 80 as default for it's
web browser interface.

However, I can't seem to get into it over the internet.

I have therefore tried setting the same machine up with IIS to see whether
THAT works, but it does not. When trying to load the page, by typing
http://my.ip.addr/ or even http://my.ip.addr:80/ it does not find the server
,
nor can i telnet to the server on that port.

I CAN use remote desktop to the same IP address. I have no firewall, or any
other network switch/hub/router connected. So my question is whether some
ISP's actually BLOCK the use of web servers or ports, and whether there is a
port i can use instead, although I have tried several different ports and
none seem to work.

Or is there a firewall on the motorola surfboard or anywhere else on the
Telenet service?

Any help would be much appreciated.
