3.4 Setting Up NAT Inbound Port Forwarding
(Port Address Translation)
When you have enabled NAT on the WAN interface, in order for people to reach your
HTTP (Web) Server, FTP Server and so on at your LAN, you need to activate the NAT
Inbound Port forwarding.
The following gives an illustration of a Web Server (IP=192.168.1.100) and FTP
Server (IP=192.168.1.101) connected to your router.
For PC A:
IP = 192.168.1.2
Subnet mask = 255.255.255.0
Gateway = 192.168.1.1
For PC B:
IP = 192.168.1.3
Subnet mask = 255.255.255.0
Gateway = 192.168.1.1
NAT Inbound Port Forwarding is not applicable for Transparent
Bridge configuration.
For Web Server:
IP = 192.168.1.100
Subnet mask = 255.255.255.0
Gateway = 192.168.1.1
For FTP Server:
IP = 192.168.1.101
Subnet mask = 255.255.255.0
Gateway = 192.168.1.1
