Routing Information Protocol. 
DHCP Server 
Configuration 
DHCP stands for Dynamic Host Configuration Protocol. 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. 
Start IP Address - The beginning LAN IP address that is given 
out to LAN DHCP clients. 
IP Pool Counts - The maximum number of IP addresses to be 
handed out by DHCP. The default value is 100. Valid range is 
between 1 and 253. The actual number of IP addresses 
available for assignment is the IP Pool Counts, or 253 minus 
the last octet of the Start IP Address, whichever is smaller. 
Gateway IP Address - The IP address of the gateway, which is 
the host on the LAN that relays all traffic coming into and 
going out of the LAN. The gateway is normally the router, and 
therefore the Gateway IP Address should be identical to the 
IP Address in the Network Configuration section above. 
Lease Time - The maximum duration DHCP-issued IP 
addresses can be used before they have to be renewed. 
Use LAN Port – Specify an IP for IP Route Subnet. If it is 
enabled, DHCP server will assign IP address automatically for 
the clients coming from P1 and/or P2. Please check the box 
of P1 and P2. 
Use MAC Address - Check such box to specify MAC address. 
  MAC Address: Enter the MAC Address of the host one by 
one and click Add to create a list of hosts which can be 
assigned, deleted or edited from above pool. Set a list 
of MAC Address for 2
nd
 DHCP server will help router to 
assign the correct IP address of the correct subnet to 
the correct host. So those hosts in 2
nd
 subnet won’t get 
an IP address belonging to 1
st
 subnet. 
Add – Type the MAC address in the boxes and click this button 
to add. 
Delete – Click it to delete the selected MAC address. 
Edit – Click it to edit the selected MAC address. 
Cancel – Click it to cancel the job of adding, deleting and 
editing. 
When you finish the configuration, please click OK to save and exit this page.
