NOTE

The

1 policy from the source IP, 192.168.127.1 to 192.168.127.252 to

the WAN1 interface after activating the Factory Default.

Port Forward

If the initial connection is from outside the LAN, but the user still wants to hide the Internal IP address, one way

to do this is to use the Port Forwarding NAT function.

The user can specify the port number of an external IP address (WAN1 or WAN2) in the Port Forwarding policy

list. For example, if the IP address of a web server in the internal network is 192.168.127.10 with port 80, the

user can set up a port forwarding policy to let remote users connect to the internal web server from external IP

address 10.10.10.10 through port 8080. The Industrial Secure Router will transfer the packet to IP address

192.168.127.10 through port 80.

The Port Forwarding NAT function is one way of connecting from an external insecure area (WAN) to an internal

secure area (LAN). The user can initiate the connection from the external network to the internal network, but

will not able to initiate a connection from the internal network to the external network.
