NAT (Network Address Translation) converts IP addresses on a private network (designated as
“LAN”) into public IP addresses, so the packets can be forwarded to another registered network
(designated as “WAN”). It enables multiple PCs inside the LAN to access the Internet by means
of one public IP address. NAT is enabled by default. By setting NAT Table, the public IP is
provided by your ISP.
1. Go to Advanced page and choose NAT and then Address Mapping.
2. Click radio button of #1 and click Edit.
3. Select TCP as the protocol.
4. Set the Private IP with 192.168.1.100 and select /24 as the Subnet Mask.
If you want to choose any on of the Public IP settings, you must specify some IP
addresses in the IP Alias List of the Static/DHCP Configuration page first. If you
did not type in any IP address in the IP Alias List, the Public IP setting will be
empty in this field. And when you click Apply, a message will appear to inform
you.
