Client DNS setup
After you install NxFilter, you need to put your client devices under the filtering by making NxFilter to be the DNS server for your network.
NxFilter to be the DNS server for your networkAfter you install NxFilter, you will want to monitor and filter Internet activity in your network. To monitor and filter Internet activity, you need to make NxFilter to be the only DNS server for your network. The simplest way of setting up NxFilter as the DNS server for your users would be modifying the network setup at OS level like the screenshot above. But you don't want to set up all the PCs in your network one by one. So the best way would be using a DHCP server. You just need to modify DNS server address on your DHCP server setup and then your users will be using NxFilter as their DNS server. If you have a firewall you can force your users to use NxFilter as their DNS server by blocking outgoing traffic on UDP/53, TCP/53 port. Now NxFilter becomes the only DNS server your users can use.
