Yes. How would you get through a door if it was locked?
It needs to be opened. Of course you could brute force it, but I doubt you’re
trying to hack yourself.

Jake:
Thanks for the data. Most of the IP stuff makes perfect sense. The first main
thing I was missing was I did not know about the settings in red5.properties (I
don't recall ever seeing that file or those settings mentioned in any of the
docs).
But I'm still having trouble with connecting the 2nd computer to the room. It
does in fact connect when I use the internal IP address 192.x.x.x But when I
try using the modem's IP address, I get "unable to connect." Based on what I
see in the other responses, it looks like I need to get access to my modem's
admin and set something for port 5080. Is that correct?

The IP you’re seeing, 192.xx.xx.xxx, is an internal IP address. The way the
internet is setup, there are billions of networks connected together. Imagine
the router and all other computers that are connected to that router, as your
network.
All computers have low firewall settings within their own network. So
naturally, connecting to 192.xx.xx.xx from another 192.xx.xx.x machine won’t
cause nearly as many security issues as connecting to the external IP address.
The way your router communicates with the world, is it has it’s own IP
address. Just like your mailing address; they’re all unique. Your router
determines WHICH internal computer(rather it be 192.168.0.1, or 192.168.0.2)
made the request and it handles the processing of that request.
Think of your router as your internet middle man. Whenever you make a request
to the internet, it first goes through your router. Your router gets the
request, something in the form of, “REQUEST FROM <computer name> TO <wherever>
SESSIONSTAMP <stamp> TTYL<time to live>”
When that request comes back from <wherever>, your router KNOWS which local
computer made the request; thus delivering the information to the computer.
Your external IP address, is your REAL ip address that is used for
communication with any and ALL computers on your network. If you wish to access
ANY resource from a networked computer, you MUST use the REAL ip address(your
routers IP.) Your router will take care of handling all of your requests, so
don’t worry about that. Just open up the ports that you need, and start your
service.
Be sure you have opened the port in Windows Firewall(or whatever OS) AS WELL
as the router.(assuming you have more than one layer of security.)
Now, once you have that set. locate the file “red5.properties”(typically
within the /dist/ folder of your openmeetings directory.) If you still cannot
find it, search your machine for it.
I was able to do a ctrl+h(replace all) and replace ALL instances of
“.host=0.0.0.0” with “.host=YourIPHere”.
Hopefully this will give you a thourough understanding of what communication
is going on between your machine, your router, and the rest of the internet.
Remember, the internet is nothing more than billions of networks that
communicate with eachother.

Dimitri,
Your comment raises a lot of questions for me.
First, are you using a laptop/desktop for your server? If so, how did you
get a domain name for it?
Second, using 'ipconfig' on my XP, I got a 192.168.x.x address that worked
fine from my 2nd computer. Was that only because it is on the same side of the
modem? Would that address not work for the rest of the world to use?
Thanks!

I've found that you need to log into OM with the FQDN of your OM server
(e.g.
http://openmeetings.mydomain.tld:5080/openmeetings). At first, I was
using the
internal address of the OM server, so my invitees were instructed to go
to the
meeting at http://192.168.x.x<meeting_id>. Clearly, that didn't work.
Others
may know of another way to accomplish what you're after.
