Can some one tell me how NAT works. I have the following problem:
I have one IP address and one 2600 series router. I have setup an internal Lan with three hosts.
I have configured my N/W with the following:
1) Assigned FastEthernet 0/0 with the IP address available (Say 220.127.116.11) & this port is connected to my ISP' via a ethernet cable.
2) Assigned 192.168.100.1 to the FastEthernet 0/1 and this port is connected to my local Lan with three hosts(192.168.100.2,192.168.100.3,192.168.100.4) using a Hub.
My N/W works fine. I want that whenever a request to my assigned IP (18.104.22.168) comes from outside it should be forwarded to my internal LAN host 192.168.100.3.
A quick help in this regard will be highly appreciated.
