Dhcp Configuration, Using an existing Dhcp Server | Apple Version 3

DHCP Configuration

NetPurifier can operate in conjunction with an existing DHCP server or with its own built-in DHCP server. In either case the key to the successful operation of NetPurifier is a redirect of the Internet Gateway IP address from the true Internet Gateway to NetPurifier. This allows NetPurifier to sit between the requesting computer and the true Internet Gateway.

Using an existing DHCP Server

If using an existing DHCP Server the following items must be configured:

1.Set Net Purifiers DNS/Gateway setting to reflect your networks IP Subnet.

2.Change your existing DHCP server to point client computers to the NetPurifier IP (gateway)

Using the NetPurifier DHCP Server

NetPurifier has a built in DHCP server. It is factory configured but not activated when shipped. If you use the NetPurifier DHCP server you will need to modify the existing factory configuration to meet your network parameters, save the configuration and Start the DHCP server
