One-to-One NAT

Network > Firewall > One-to-One NAT
If you have multiple static public WAN/Internet IP addresses assigned by your ISP, you
can map the additional public IP addresses to a local computer or device on your
network and allow all or specific ports or services similar to port forwarding but using
different public IP addresses through your router. Please check with your ISP if you have
multiple static public IP addresses available that can be used to map to devices on your
local network.
Note: This feature will only work when using a static IP address WAN type/protocol.
