One-to-One NAT Configuration
Use the One-to-one Network Translation (NAT) page to map local IP addresses
behind your firewall to global IP addresses. One-to-one NAT is a way to make

to have public IP addresses.
To add a One-to-One NAT rule:
STEP 1
Select
Firewall > One-to-One NAT

IP address range.
STEP 5
In the
Range Length
, enter the number of public IP addresses that should be
mapped to private addresses.

In the
Service

(LAN) address when traffic is sent to the corresponding public IP address.
Configured services on private IP addresses in the range are accepted when
traffic is available on the corresponding public IP address.
