PPPoE Passthrough | If you want to use PPPoE server in the network via Vigor  | |
  | router, please check this box to redirect the PPPoE frames  | |
  | to the specified location.  | 
  | 
DHCP Server | DHCP stands for Dynamic Host Configuration Protocol.  | |
Configuration | The router by factory default acts a DHCP server for your  | |
  | network so it automatically dispatch related IP settings to  | |
  | any local user configured as a DHCP client. It is highly  | |
  | recommended that you leave the router enabled as a DHCP  | |
  | server if you do not have a DHCP server for your network.  | |
  | If you want to use another DHCP server in the network  | |
  | other than the Vigor Router’s, you can let Relay Agent help  | |
  | you to redirect the DHCP request to the specified location.  | |
Enable Server | Let the router assign IP address to every host in the LAN.  | |
Disable Server | Let you manually assign IP address to every host in the  | |
  | LAN.  | 
  | 
Start IP Address | Enter a value of the IP address pool for the DHCP server to  | |
  | start with when issuing IP addresses. If the 1st IP address  | |
  | of your router is 192.168.1.1, the starting IP address must  | |
  | be 192.168.1.2 or greater, but smaller than 192.168.1.254.  | |
End IP Address | Enter a value of the IP address pool for the DHCP server to  | |
  | end with when issuing IP addresses.  | |
Subnet Mask  | Type in an address code that determines the size of the  | |
  | network. (Default: 255.255.255.0/ 24)  | |
Default Gateway  | Enter a value of the gateway IP address for the DHCP  | |
  | server. The value is usually as same as the 1st IP address of  | |
  | the router, which means the router is the default gateway.  | |
Lease Time | It allows you to set the leased time for the specified PC.  | |
DNS Manual Setting | If this function is enabled, LAN PCs use Primary DNS  | |
  | Server and Secondary DNS Server as their DNS servers.  | |
  | Otherwise, LAN PCs use the router as their DNS server  | |
  | and the router will do DNS proxy for them.  | |
Primary DNS Address | You must specify a DNS server IP address here because  | |
  | your ISP should provide you with usually more than one  | |
  | DNS Server. If your ISP does not provide it, the router will  | |
  | automatically apply default DNS Server IP address:  | |
  | 194.109.6.66 to this field.  | 
  | 
Secondary DNS Address | You can specify secondary DNS server IP address here  | |
  | because your ISP often provides you more than one DNS  | |
  | Server. If your ISP does not provide it, the router will  | |
