OPENING NETMEETING ON INTERNET

Hi, in this tutorial I will explain how to open netmeeting connections between two remote sites across internet. For this I am using 256 kbps connection by applying Committed Access Rate (CAR). consider the scenario:


Here  I have used two routers as  shown in diagram. Ports I used to map statically to public are as follows:

To establish outbound NetMeeting connections through a natting, the natting must be configured to do the following:


* Pass through primary TCP connections on ports 522, 389, 1503, 1720 and 1731.
* Pass through secondary UDP connections on dynamically assigned ports (1024-65535).
 
For furhtur info. u can access this site: http://support.microsoft.com/kb/158623
 
 
 
static natting configuration on both routers are nearly same:
 
On R0:
 
ip nat inside source static tcp 192.168.1.3 389 10.1.1.1 389 extendable

ip nat inside source static tcp 192.168.1.3 522 10.1.1.1 522 extendable
ip nat inside source static tcp 192.168.1.3 1503 10.1.1.1 1503 extendable
ip nat inside source static tcp 192.168.1.3 1720 10.1.1.1 1720 extendable
ip nat inside source static tcp 192.168.1.3 1731 10.1.1.1 1731 extendable
 
 
On R1:
 
ip nat inside source static tcp 192.168.56.200 389 10.1.1.2 389 extendable
ip nat inside source static tcp 192.168.56.200 522 10.1.1.2 522 extendable
ip nat inside source static tcp 192.168.56.200 1503 10.1.1.2 1503 extendable
ip nat inside source static tcp 192.168.56.200 1720 10.1.1.2 1720 extendable
ip nat inside source static tcp 192.168.56.200 1731 10.1.1.2 1731 extendable
 
Note:
 
I didn't check audio after configuring these above commands on routers. Pls, feel free to give comments on if you have any update on this
 
Commands for applying CAR on both routers on serial interfaces:
 
 
interface Serial1/0

ip address 10.1.1.2 255.255.255.252
ip nat outside
ip virtual-reassembly
rate-limit input access-group 1 256000 64000 64000 conform-action transmit exceed-action drop
rate-limit output access-group 1 256000 64000 64000 conform-action transmit exceed-action drop
serial restart-delay 0
end

Deploying Networks by using IGPs (OSPF and EIGRP) Redistribution BASIX ONLY

This is my simple network but intuitive. Hear I will not explain too much but some lit on it.

Upper half of the network is configured with OSPF(R1, R2, R3).

Lower half is configured with EIGRP(R3, R4, R5). You might be thinking why R3 is common in this network configuration. Coz it is only router where redistribution taking place.

There is one thing more in R3 configuration. The cloud C1 which is connected to R3. What is the purpose of this. This is your assignment to understand. LOL!

Configuration of R3 is:
