Port forward

This is a way to forward incoming connections from a network interface to a client device located on a different network interface.

The forwarding rules always apply to the network interface which is configured as the NAT gateway.

If the NAT gateway configuration is moved to a different network interface, the port forwarding rules will follow automatically.

For example:

If the WLAN network interface is configured as NAT Gateway, then only incoming connections from this interface will be forwarded.

Later the cellular network interface is configured as NAT Gateway,and only incoming connections from this interface will be forwarded, no changes to the port forwarding rules are necessary.

If no rules are defined, no incoming socket connections will be forwarded to other network interfaces.

The following functions can be used to configuring port forwarding.

	•netPortForwardClear	Clear all port forward rules.
	•netPortForwardGet	Retrieve a port forward rule.
	•netPortForwardSet	Set a port forward rule.
