4-Port SSL/IPSec VPN Router
DHCP Tab - Setup
The Router can be used as a DHCP (Dynamic Host Configuration Protocol) server on your network. A DHCP server
automatically assigns available IP addresses to computers on your network. If you choose to enable the DHCP
server option, all of the PCs on your LAN must be set to obtain an IP address automatically from a DHCP server.
(By default, Windows computers are set to obtain an IP automatically.)
If the Router's DHCP server function is disabled, you have to carefully configure the IP address, subnet mask, and
DNS settings of every computer on your network. Be careful not to assign the same IP address to different
computers.
You can also set up to 30 static IP entries on this screen.
Setup
Enable DHCP Server. Check the box to enable the DHCP Server. If you already have a DHCP server on your
network, leave the box unchecked.
Dynamic IP
Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the
Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”
this dynamic IP address. The range is 5-43,200 minutes.
Dynamic IP Range Start/End. Enter a starting IP address and ending IP address to create a range of available IP
addresses. The default range is 100-149. Enter a value for the DHCP server to start with when issuing IP
addresses. This value must be 192.168.1. 2 or greater, because the default IP address for the Router is
192.168.1.1
.
DNS
DNS Server. You can assign DNS server(s) to the DHCP clients so the Router will use the DNS server(s) for faster
access to functioning DNS server(s). At least one DNS server IP address is required.
WINS
WINS Server. Windows Internet Naming Service (WINS) is a service that resolves NetBIOS names to IP addresses.
WINS is assigned if the computer (DHCP client) requests one. If you do not know the IP address of the WINS
server, keep the default,
0.0.0.0
.
