CNET CNWR-811P manual Package Contents, Security Features, NAT Firewall Protection

Introduction

Security Features

•Configuration Data. Optional password protection is provided to prevent unauthorized users from modifying the configuration.

•Access Control Features. The LAN Administrator can limit Internet access by individ- ual workstations.

•Wireless LAN Security. WEP (Wired Equivalent Privacy) is supported, as well as Wireless access control via station address.

•Firewall Protection. All incoming data packets are monitored and all incoming server requests are filtered, thus protecting your network from malicious attacks from external sources. (This protection is lost if NAT is disabled.)

NAT Firewall Protection

The firewall protection provided by the CNWR-811P 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 CNWR-811P acts as a “transparent proxy server”, translating the multiple internal IP addresses into a single external IP ad- dress.

For external requests, any attempt to connect to local resources are blocked. The CNWR-811P 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.
