8) How do I use NetMeeting with my D-Link Router?
Unlike most TCP/IP applications, NetMeeting uses DYNAMIC PORTS instead of STATIC PORTS. That means that each NetMeeting connection is somewhat different than the last. For instance, the HTTP web site application uses port 80. NetMeeting can use any of over 60,000 different ports.
All broadband routers using (only) standard NAT and all internet sharing programs like Microsoft ICS that use (only) standard NAT will NOT work with NetMeeting or other h.323 software packages.
The solution is to put the router in DMZ.
Note: A few hardware manufacturers have taken it on themselves to actually provide H.323 compatibility.This is not an easy task since the router must search each incoming packet for signs that it might be a netmeeting packet. This is a lot more work than a router normally does and may actually be a weak point in the firewall.

9) What is NAT?
NAT stands for Network Address Translator. It is proposed and described in RFC- 1631 and is used for solving the IP Address depletion problem. Basically, each NAT box has a table consisting of pairs of local IP Addresses and globally unique addresses, by which the box can “translate” the local IP Addresses to global address and vice versa. Simply put, it is a method of connecting multiple computers to the Internet (or any other IP network) using one IP Address.
