o Enable LAN NAT --
Enable LAN NAT
When only NAT is enabled
(checked), the system uses masquerading, the system will
masquerade as the WAN IP address for PC data devices on the private
LAN of the system.
o Static NAT Client Entries --
Static NAT is a special form of NAT
that allows the system to map public IP address and port pairs to a
specific IP address and port running on the LAN. The public IP address
can be either the system's WAN address or another IP address in the
same subnet. For Static NAT to function, WAN NAT must be enabled.
Note: NAT can be used to translate the LAN IP addresses to the public
routable IP address that is assigned to the WAN port.
☞
The TCP port forwards (will use reverse masquerading if
you use masquerading or static NAT. The form is;
"PROTO;WANIPAddress/netmask-port>LANIPAddress-port
udp;65.124.113.12/255.255.255.0-8080>192.168.1.54-80
☞
The UDP port forwards (will use reverse masquerading if
you use masquerading or static NAT). The form is;
"PROTO;WANIPAddress/netmask-port>LANIPAddress-port
udp;65.124.113.12/255.255.255.0-8080>192.168.1.54-80
☞ Use the following to configure DNAT and SNAT rules.
You need a spare public IP to set this up. All traffic
destined for the Public IP will be directed to the private IP
and all traffic coming from the private IP will appear to
come from the Public IP.
"PROTO;WANIPAddress/netmask-port>LANIPAddress-port
any;65.124.113.13/255.255.255.0-any>192.168.1.54-any
