Edit One-to-One NAT (Network Address Translation)
One-to-One NAT maps a specific private/local IP address to a global/public IP address.
If you have multiple public/WAN IP addresses from you ISP, you are eligible for One-to-One
NAT to utilize these IP addresses.
• NAT Type: Select the desired NAT type. As set in default setting, it disables the One-to-
One NAT function.
• Global IP Address:
o Subnet: The subnet of the public/WAN IP address given by your ISP. If your ISP
has provided this information, you may insert it here. Otherwise, use IP Range
method.
o IP Range: The IP address range of your public/WAN IP addresses. For example,
IP: 192.168.1.1, end IP: 192.168.1.10
