14 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 whole lot more work

than a router normally does and may actually be a weak point in the ﬁrewall. D-Link

is not one of the manufacturers.

15 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.

D-Link´s broadband routers (ie: DI-LB604) support NAT. With proper conﬁguration,

multiple users can access the Internet using a single account via the NAT device.
