I am on a router and am trying to communicate with my parents who are also on a router using NetMeeting.

Question

I am on a router and am trying to communicate with my

parents who are also on a router using NetMeeting.

I am trying to help them make some adjustments on

their computer which was easy before we both got routers.

What is the best way to do this? I would like to have it so

they can call me through Netmeeting using the same IP address,

email or whatever. I have opened up TCP ports as directed by

Microsoft Knowledge base article 158623 but am confused when

my D-link router asks for Private and Public port settings as well

as an IP address. I assume that the private IP address is the same

as the router??

I hope you can help me with this or direct me where I can get help

and your recommendations on setting up NetMeeting or if I should

use something else (Windows Messenger).

This question was answered on February 18, 2003. Much of the information contained herein may have changed since posting.

When using Netmeeting on a on a home network that uses a router its going to be difficult to communicate with a remote computer on a different network such as your parents computer (Remote meaning at a different location with different router configurations.)

The reason is because when you buy a router it comes with what is called a private ip address

The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of

the IP address space for private internets:

10.0.0.0 - 10.255.255.255 (10/8 prefix)

172.16.0.0 - 172.31.255.255 (172.16/12 prefix)

192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

Lets take a look at this scenario

Imagine that a million people bought the same brand of router as you did that means a million might have the same ip address on their router as you do These set of Ip address allow anybody to configure a small home network with out having their adddress broadcasted over the net.

What i suggest you do when trying to coonect to your parents computer over the internet by using net meeting unplug you router connect your internet connector cable directly to your computers network card (inform your parents to do the same) and try the netmeeting that way This should work out find.
