Chapter 27 Product Specifications and Wall-Mounting Instructions Table 116 Firmware Features FEATURE DESCRIPTION Firewall You can configure firewall on the NBG-460N 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. Content Filter The NBG-460N 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 NBG-460N to check web sites against an external database. IPSec VPN This allows you to establish a secure Virtual Private Network (VPN) tunnel to connect with business partners and branch offices using data encryption and the Internet without the expense of leased site-to-site lines. The NBG-460N VPN is based on the IPSec standard and is fully interoperable with other IPSec-based VPN products. Bandwidth Management You can efficiently manage traffic on your network by reserving bandwidth and giving priority to certain types of traffic and/or to particular computers. Wireless LAN Scheduler You can schedule the times the Wireless LAN is enabled/ disabled. Time and Date Get the current time and date from an external server when you turn on your NBG-460N. You can also set the time manually. These dates and times are then used in logs. Port Forwarding If you have a server (mail or web server for example) on your network, then use this feature to let people access it from the Internet. DHCP (Dynamic Host Configuration Protocol) Use this feature to have the NBG-460N assign IP addresses, an IP default gateway and DNS servers to computers on your network. Dynamic DNS Support With Dynamic DNS (Domain Name System) support, you can use a fixed URL, www.zyxel.com for example, with a dynamic IP address. You must register for this service with a Dynamic DNS service provider. IP Multicast IP Multicast is used to send traffic to a specific group of computers. The NBG-460N supports versions 1 and 2 of IGMP (Internet Group Management Protocol) used to join multicast groups (see RFC 2236). IP Alias IP Alias allows you to subdivide a physical network into logical networks over the same Ethernet interface with the NBG-460N itself as the gateway for each subnet. Logging and Tracing Use packet tracing and logs for troubleshooting. You can send logs from the NBG-460N to an external syslog server. PPPoE PPPoE mimics a dial-up Internet access connection.
