[. . . ] The router has multiple IP addresses (8 or 16 in most instances). If you have only one IP address click on the PPPoE/DHCP/Static tab. If you have multiple IP addresses, click on the PPPoE Unnumber tab. The DMZ Support tab allows you to enable a Demilitarized Zone (Zone) on your network. The DMZ Setting Tab With a firewall setup, it sometimes necessary to place some clients (e. g. Internet games, video conferencing, or VPN connections) outside of the firewall while leaving the others protected. You can do this using a Demilitarized Zone. The DMZ feature allows you to specify the IP address of the computer that will be placed outside the firewall of your network. Enter the IP Address of your computer (e. g. 192. 168. 1. 2) into the LAN IP Address field and click the Submit button. A computer designated as the default DMZ server loses much of the protection of the firewall, and is exposed to exploits from the Internet. If compromised, the DMZ server can be used to attack your network. 35 GB21222-RH 2. 4GHz AirCruiser Extreme N Wireless Router The Virtual Server PPPoE / DHCP / Static Configuration Tab The GB21222-RH is configurable to behave as a Virtual Server, allowing remote computers on the WAN (Internet) side of the network to be automatically redirected to local server(s) on the LAN (your private network) side of the network. You can specify the Router to drop (or accept) all packets which meets the Rule criteria. Direction Specify the packet flow direction according to data filtering rule. W->L: WAN to LAN, filtering incoming packets b. L->W: LAN to WAN, filtering outgoing packets Protocol Select a setting from the drop-down list to specify the protocol (s) for the static rule. Log Enable or disable the log feature. 41 GB21222-RH 2. 4GHz AirCruiser Extreme N Wireless Router The DNS Configuration Screen DNS Relay DNS Relay will set your PC's DNS entries to point to the Router’s Gateway address, which will then forward DNS queries to the DNS server used by the Router. This is needed when using DHCP to assign IP address to the PC’s in you LAN. The default value of DNS relay is Enable. Dynamic DNS The GB21222-RH offers a Dynamic Domain Name Server (DDNS) service that allows you to assign a fixed host and domain name to a dynamic Internet IP address. This gives Internet users the ability to connect with a virtual sever using a FQDN, rather than with an IP address. Before using this feature, you must first register an account with the dynamic DNS service.
