Configuring One-to-One Network Address Translation (NAT)
Use the One-to-one NAT page to map local IP addresses behind your firewall to
global IP addresses. One-to-one NAT is a way to make systems configured with
private IP addresses, which are behind a firewall, appear to have public IP
addresses.
To add a One-to-One NAT rule:
STEP 1 Choose Firewall > One-to-One NAT.
STEP 2 Click Add Row.
STEP 3 In the Private Range Begin field, enter the starting IP address in the private (LAN) IP
address range.
STEP 4 In the Public Range Begin field, enter the starting IP address in the public (WAN) IP
address range.
STEP 5 In the Range Length, enter the number of public IP addresses that should be
mapped to private addresses.
STEP 6 In the Service field, choose the service for which the rule applies. Services for
one-to-one NAT allow you to configure the service to be accepted by the private
IP (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.
STEP 7 Click Save.
Configuring Port Forwarding
Port forwarding is used to redirect traffic from the Internet from one port on the
WAN to another port on the LAN. Common services are available or you can define
a custom service and associated ports to forward.
The Single Port Forwarding Rules and Port Range Forwarding Rules pages list
all the available port forwarding rules for this device and allow you to configure
port forwarding rules.
