Can I host a NetMeeting if I use a router?

I tried to host a NetMeeting (the application built into windows). It
appears that all my computers on the network have the same IP address. This
seems to cause a problem when I try to access the hosted meeting, the
application says "the host is unable to receive your call" or something to
that affect.

Is there any way to host a NetMeeting if you're behind a router that assigns
the same IP address to every computer on the network?

I assume that your seeing the same IP address when going to whatsmyip.com or
similar page. This would be your WAN, or Public IP address. (if all your
machines had the same IP, your network wouldn't work) You'll need to tell
your router to send all inbound traffic to one machine. To do this, you need
to set the "DMZ" of the router to the one machine you want to run netmeeting
on.

It'd really be a good idea to set the selected machine up with a static IP
address on your LAN. Typically, home routers are set up to use
192.168.1.XX... as an IP set. This way when you reboot your machine the IP
address will always agree with the DMZ setting in the router. For whatever
reason, I always set the last octet to 10 for DMZ use.

Hi,

although NAT prevents Internet locations from directly accessing the PCs on
the LAN, the router allows you to direct incoming traffic to specific PCs
based on the service port number of the incoming request, or to one
designated "DMZ" host computer. You can specify forwarding of single ports
or ranges of ports. Use the Port Forwarding menu to configure the router to
forward incoming protocols to computers on your local network. In addition
to servers for specific applications, you can also specify a Default DMZ
Server to which all other incoming protocols are forwarded. Be careful: DMZ
servers pose a security risk. A computer designated as the default DMZ
server loses much of the protection of the firewall, and is exposed to
exploits from the Internet. If compromised, the DMZ server can be used to
attack your network.

Bye

thanks, I'll try the DMZ thing... a couple questions---

how is that I can use Instant Messaging (like AOL or Yahoo) on the two
machines that share a router, even without the DMZ set up? Don't they also
use the IP address to deliver messages?

and, for some reason I am able to join a Net Meeting, even without the DMZ
set up. It just seems to croak when I try to host one. Is that normal,
given the router setup I have?

thanks

Netmeeting (hosting) works differently than AIM, Yahoo, and the such.
Mainly, all those clients initiate contact with a known server to establish
a connection. By hosting a netmeeting, your attempting to be the known
server the other clients are logging on to. Their "knock knock" to your chat
gets lost at the router door without the DMZ....
