Appendix A Product Specifications Table 111 Firmware Features FEATURE DESCRIPTION Port Forwarding If you have a server (mail or web server for example) on your network, you can use this feature to let people access it from the Internet. DHCP (Dynamic Host Configuration Protocol) Use this feature to have the P-794H 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 P-794H supports versions 1 and 2 of IGMP (Internet Group Management Protocol) used to join multicast groups (see RFC 2236). Time and Date Get the current time and date from an external server when you turn on your P-794H. You can also set the time manually. These dates and times are then used in logs. Logging and Tracing Use packet tracing and logs for troubleshooting. You can send logs from the P-794H to an external syslog server. PPPoE PPPoE mimics a dial-up Internet access connection. Universal Plug and Play (UPnP) A UPnP-enabled device can dynamically join a network, obtain an IP address and convey its capabilities to other devices on the network. Firewall You can configure firewall on the P-794H 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. 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. Remote Management This allows you to decide whether a service (HTTP or FTP traffic for example) from a computer on a network (LAN or WAN for example) can access the P-794H. 230 P-794H User's Guide
