Figure 11 (Example of a DHCP Relay configuration)
By turning off the DHCP server and relay the network administrator must carefully configure the IP
address, Subnet Mask and DNS settings of every computer on your network. Do not assign the same
IP address to more than one computer and your Gateway must be on the same subnet as all the other
computers.
The apply button will temporarily save this connection. To make the change permanent you need to

3.5.2.1
STATIC IP ADDRESS ASSIGNMENT
Your gateway’s default IP address and subnet mask are 192.168.1.1/255.255.255.0; this subnet mask
will allow the gateway to support 254 users. If you want to support a larger number of users you can
change the subnet mask; but remember. The DHCP server is defaulted to only give out 255 IP
addresses. Further remember that if you change your gateways’ IP address and you have DHCP
enabled, the DHCP configuration must reside within the same subnet
The default gateway is the routing device used to forward all traffic that is not addressed to a station
within the local subnet. Your ISP will provide you with the default gateway Address. Figure 12
shows a default gateway address of 10.247.16.1 because this was the default gateway defined when
the CLIP connection was configured.
The hostname can be any alphanumeric word that does not contain spaces. The domain name is used
to in conjunction with the host name to uniquely identify the gateway. To access the gateway’s web
pages the user can type 192.168.1.1 (the gateway’s default IP address) or type mygateway.
