IP Address Filtering MAC Address Filtering Port Filtering Port Forwarding Port Triggers DMZ Host (Demilitarized Zone) on the network. Use this page to configure IP address filters. These filters prevent designated IP addresses from accessing the Internet. Use this page to configure MAC address filters. These filters prevent designated MAC addresses from accessing the Internet. Use this page to configure TCP and User Datagram Protocol (UDP) port filters. These filters prevent a range of TCP/UPD ports from accessing the Internet. Use this page to configure port forwarding for local IP addresses. Port forwarding allows a server to be run on the LAN by specifying the mapping of TCP/UPD ports to local PCs or to the IP address of other devices. This is a static setting that holds the ports open at all times. Use this page to configure TCP/UPD port triggers. Port triggering is similar to port forwarding, but is a dynamic function. In other words, the ports are not held open, and the ports close if no outgoing data is detected on the selected ports for a period of 10 minutes. Use this page to configure an IP address that is visible to the WAN. DMZ hosting is commonly referred to as exposed host, and allows to specify the default recipient of WAN traffic that NAT is unable to translate to a known local PC. A DMZ is used by a company that wants to host its own Internet services without sacrificing unauthorized access to its private network. DMZ allows one IP address to be unprotected while others remain protected. The DMZ is located between the Internet and an internal network s line of defense that is a combination of firewalls and bastion hosts. Typically, the DMZ contains devices accessible to Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP (e-mail) servers, and domain name system (DNS) servers. Firewall

Select 1, 2 Mbps if older 802.11 compliant equipment, such as wireless adapters that support only 1 or 2 Mbps is on the network. Faster wireless adapters can support the second choice from the drop-down menu: 1, 2, 5.5, 11 Mbps. This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Gateway to keep the network synchronized. A beacon includes the wireless LAN service area, the IP address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic Indicator Message (TIM). This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Gateway has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Clients for the Gateway hear the beacons and awaken to receive the broadcast and multicast messages. This value indicates how much of the Gateway s resources are devoted to recovering packet errors. The value should remain at its default setting of 2,346. If this value has been decreased, and high packet error rates are experienced,
RTS Threshold increase it again, however, it will likely decrease overall network performance. Only minor modifications of this value are recommended. This value should remain at its default setting. Should inconsistent data flow be encountered, only minor modifications are recommended. 1. Click the Apply button to save any changes.
