Wireless Functionality Allows IEEE 802.11b and/or IEEE 802.11g and/or IEEE 802.11n wireless clients to connect to the NBG420N wirelessly. Enable wireless security (WEP, WPA(2), WPA(2)-PSK) and/or MAC filtering to protect your wireless network. Firmware Upgrade Note: The NBG420N may be prone to RF (Radio Frequency) interference from other 2.4 GHz devices such as microwave ovens, wireless phones, Bluetooth enabled devices, and other wireless LANs. Download new firmware (when available) from the ZyXEL web site and use the web configurator, an FTP or a TFTP tool to put it on the NBG420N. Configuration Backup & Restoration Network Address Translation (NAT) Firewall Content Filter Note: Only upload firmware for your specific model! Make a copy of the NBG420N's configuration and put it back on the NBG420N later if you decide you want to revert back to an earlier configuration. Each computer on your network must have its own unique IP address. Use NAT to convert a single public IP address to multiple private IP addresses for the computers on your network. You can configure firewall on the NBG420N for secure Internet access. When the firewall is on, by default, all incoming traffic from the Internet to your network is blocked unless it is initiated from your network. This means that probes from the outside to your network are not allowed, but you can safely browse the Internet and download files for example. The NBG420N blocks or allows access to web sites that you specify and blocks access to web sites with URLs that contain keywords that you specify. You can define time periods and days during which content filtering is enabled. You can also include or exclude particular computers on your network from content filtering. You can also subscribe to category-based content filtering that allows your NBG420N to check web sites against an external database. 274 NBG420N User's Guide
