About your Internet Router

Firewall Protection

The firewall protection provided by the Internet Router is an intrinsic side effect

of IP sharing. 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 Internet 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

Internet 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.
