I’ve used one of these routers to configure Remote Desktop through the one
router to multiple PCs. I connect to (say) xxx.xxx.xxx.xxx:8049 and the
2Wire routes it to the designated machine (typically local IP 10.0.0.49),
translating the port to 3389 on the fly (“map to host port”). Works a
treat.
On this router you edit (create) an “Application” for each type of
connection: I call mine something like (eg) RDC-8049, and have it “map to
host port” 3398. Exactly the same for VNC: I’d have an Application called
VNC-8049 and map that to host port 5900. Then I select the desired computer
from the “Select a computer” drop-down (numbered “1” in the screenshot on
the site below) and add it to the “Hosted Applications” list for that
machine.
If your router isn’t correctly detecting the connected PCs then I’d guess a
power-cycle might help, but I can’t help further with that.

This tutorial is good to connect to only one PC detected by the router.
I will write 2Wire's support to know what do I need to do for the router to
detect all the machines, not just a few.
Thanks

Check this:

I must say I’ve also had problems with 2Wire modems not apparently detecting
machines which are connected through it, so the hard-reset might be a good
idea.
Regarding Christopher’s comment about the double-colon, for all I know they
have removed the requirement for the second colon – I’ll have to try it some
time!

The problem is that things don't work that way for this particular router.
First, you are forced to select a set of computers "detected" by the router
from a drop down menu list and then configure which ports are associated
with that particular PC's.
Problem is not all the 8 PC's appear on that list I don't know why so
there's no way to select all the IP addresses from all the PC's.
Unfortunately you cannot manually type the IP addresses for all PC's. Some
of them are there and some aren't.
Maybe I need to do a hard reset to the router so it detects all the machines
connected to it.

I assume you’ve configured VNC server on PC5 to use port 5905 (and so on).
You’ve also added a firewall exception for port 5905 on that machine (you
could have just trusted the application and the firewall will figure out
which port is involved). If I understand you correctly, then what’s missing
is a port-forwarding rule in the router which will direct incoming
connections using port 5905 to the IP address of PC5. And so on, for the
other machines.
Can’t remember what the 2Wire interface looks like, but many routers call
these rules “Virtual Servers”.
Be aware that VNC requires TWO colons if you are using anything other than
the default port, so your address should be: papeleria.no-ip.org::5901

Hello:
I think I'm missing something on my 2Wire 2701HG-T router configuration or
somewhere else.
I can only connect to the PC (the main one) that has the No-IP client
installed.
I added an exception on Windows XP firewall on each of the 7 PC's
So for the main PC I added the exception port TCP 5900
So for PC1 I added the exception port TCP 5901
So for PC2 I added the exception port TCP 5902
So for PC3 I added the exception port TCP 5903
So for PC4 I added the exception port TCP 5904
So for PC5 I added the exception port TCP 5905
So for PC6 I added the exception port TCP 5906
I'm entering on the VNC Viewer papeleria.no-ip.org:5901 to try to connect to
PC1 but I can't.
How am I supposed to configure the router?
What I did was to forward ports 5900 through 5901 to the IP address if the
main PC (192.168.1.71) where the No-IP client is installed.
Am I missing something?
Thanks
