NAT Firewall Protection
The firewall protection provided by the Broadband Router is an intrinsic side effect of NAT (Network Address Translation). All users on the LAN share a single external IP address. From the external viewpoint, there is no network, only a single device.
For internal users, the Broadband Router acts as a “transparent proxy server”, translating the multiple internal IP addresses into a single external IP address.
For external requests, any attempt to connect to local resources are blocked. The Broadband Router will not “reverse translate” from a global IP address to a local IP address.
This type of “natural” firewall provides an impregnable barrier against malicious attacks.
