LevelOne WBR-1101TX User Guide
NAT Firewall Protection
The firewall protection provided by the LevelOne WBR-1101TX 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 LevelOne WBR-1101TX 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 is blocked. The
LevelOne WBR-1101TX will not "reverse translate" from a external IP address to a
local IP address.
This type of "natural" firewall provides an impregnable barrier against malicious
attacks.
