3. CONFIGURATION
In this example there is additional equipment connected behind the router, using a Switch.
Every device connected behind the router has its own IP address. This is the address to enter
in the
Server IP Address
field in the NAT configuration. All of these devices will be communi-
cating on port 80, but you can configure the Port Forwarding in the NAT configuration
Public
Port
and
Private Port
fields. It is now configured to access 192.168.1.2:80 socket behind the
router when accessing 10.0.0.1:81 from the Internet, and so on. If you send the ping request to
the public IP address of the router (10.0.0.1), the router will respond as usual (not forwarding).
If you access the IP address 10.0.0.1 in the browser (it is port 80), nothing will happen – Port
80 in the Public Port list is not defined, and you have not checked the
Enable remote HTTP
access on port 80
. And since the
Send all remaining incoming packets to default server
is not
enabled, the attempt to connect will fail.
