Source NAT Settings
These settings are available when the rule manages traffic being allowed from the LAN / DMZ
to the INSECURE (Dedicated WAN/Configurable WAN). Source Network Address Translation
(SNAT) requires rewriting the source or destination IP address of incoming IP packets as they pass
through the firewall.
Note: Source NAT Settings options will be configurable if at least one WAN is in NAT Routing Mode
independent of the WAN Mode configured.
You can select any one of the following: WAN Interface Address or IP Aliasing. In case, IP Aliasing
is selected, select an IP Alias from the drop-down list.
Destination NAT Settings
These settings are required when the traffic is coming from the INSECURE (WAN) to the DMZ,
SECURE (VLAN), or SECURE (LAN). Destination Network Address Translation maps a public IP ad-
dress (your WAN1 address, WAN2 address, or another address) to an IP address on your private
network.
Specify an IP address of a machine on the Local Network which is hosting the server.
Toggle it to ON state to enable port forwarding to the port that you specify in the Translate Port
Number field. These settings are required when the traffic is coming from the SECURE (LAN) to the
DMZ or SECURE (VLAN).
Enter the port number to use for port forwarding. For example, if a machine on the Local Network
side is running a telnet server on port 2000, then check the Enable Port Forwarding box and type
2000 in the Translate Port Number field. If the server is listening on the default port 23, then the
box can be left unchecked.
Select the Internet destination IP address that is used for this firewall rule: Dedicated WAN, Con-
figurable WAN, or WAN3 (Mobile Internet).
Click Save to activate your settings.
