Question ID: 772828
I am trying to open up a port on my firewall to boost my connection to
the internet. For uTorrent, actually. I have both a 2Wire (HomePortal
1100 if that matters) DSL modem that is connected, via Ethernet cable,
to a Motorola WR850G wireless router. This setup has enabled those of
us in my apartment to enjoy the benefits of a wireless network with
semi-wild abandon.

To give you an update of where I am right now, I have followed the
directions found here
(http://www.portforward.com/english/applications/port_forwarding/Utor/Utorindex.htm)
for setting up port forwarding on each of my two devices, but yet I
keep getting the message:

"Welcome to the µTorrent Port Checker.
A test will be performed on your computer to check if the specified port is opened.

Checking port 15506 on 72.150.153.169...

Error! Port 15506 does not appear to be open."

... whenever I test the port. As can be seen, the port I am trying to
open is 15506.

My 2Wire modem sees only the wireless router as a connected device and
has assigned it an IP address that ends in .33. The computer on the
network I wish to use has an IP ending in .8. Is this a problem? If
so, how do I fix it without hard wiring a computer in to the little
setup? We have laptops that need to be portable (get taken to and from
work) so cabling one in is not an option.

Ask an I will clarify, such as I can.

I will clarify my question to be, "How can I port forward 15506 with
my described setup?"

Are you using a firewall software (like Zone Alarm, Norton Internet
Security or Kerio for example)? If yes try check the port disabling it
and tell us wich firewall you are using.

Thank you.

Nope, no software firewall since my modem and router both have
complicated and comprehensive ones built in. Which is, of course,
where the problem stems from.

theinfamousj-ga:

Are you operating the Motorola WR850G in its Router mode, or in its
Access Point (AP) mode? My normal recommendation to anyone with an
integrated DSL modem/router who wishes to add wireless networking
capabilities, is to use an Access Point rather than a wireless router,
to avoid issues such as double Network Address Translation (NAT),
double firewall rulesets, and double port forwarding rulesets. In your
case, the WR850G can be configured to act as just an AP, meaning that
all router and DHCP activities will be handled by the HomePortal only.
The advantage to this is that the HomePortal will then 'see' all of
the wireless devices (your laptop computers), and will allow you to
then take advantage of 2Wire's more-user-friendly approach to firewall
and access rulesets (ie. using reserved dynamic IP addresses
associated with your computer's name, rather than forcing you to use
static IP addresses or look up MAC addresses for each PC).

If you are indeed using the WR850G in its Router mode, you can change
it to AP mode from the 'Basic' configuration page in the WR850G's
web-based configuration system. Note that once you have changed the
mode to AP, you will need to either reboot your PCs, or disable/enable
the wireless network adapters in your PCs, to have them acquire new IP
addresses from the HomePortal. Also note that once you have switched
the Motorola WR850G to AP mode, you will no longer have easy access to
its configuration pages; the only way to access them is to either
temporarily assign your PC a static IP address in the same range as
the WR850G's self-assigned static IP address (factory default being
192.168.10.1, so you would use 192.168.10.2 as the static IP for your
PC in order to manage the WR850G in the future), or you can simply
hold down the reset button on the WR850G for 5 seconds to reset it to
its factory default settings (you would need to reset all of your
configuration settings after this, though).

Please take a look at your 850G's current settings, and let us know if
changing it to AP mode solves your problem.

Sorry to take so long to get back to you but life being what it is ...

Either the AP mode move solved the problem or the blackout that we had
just today solved the problem as it caused both pieces of networking
equipment to reboot. But whatever it did, it works.

How can I pay you?

theinfamousj-ga:

I'm glad to hear that your problem is fixed. Given the description of
your network, I'm pretty sure it was reconfiguring the Motorola WR850G
that allowed you to open the port all the way through to your PC,
rather than the blackout. Be sure to make a note of your current
configuration, in case you ever need to manually re-set the two
devices.

As an added note, your HomePortal should now be able to see all of
your computers on your home network, so you can now take advantage of
all of the other features that 2Wire provides in their configuration
menus.

I'm glad to have been of help! By posting this as an Answer, your
