If you are looking for DNS filtering software, then consider NxFilter. This freeware can help you monitor Internet use on your network with relative ease. In addition, the software will help you block malware and botnet using DNS packet inspection. Although many new routers incorporate firewalls and other filters to protect against online attacks, the filters generally offer very limited configuration. NxFilter filters both outgoing and incoming network traffic and provides a complete log with web browsing history.

Using NxFilter

The software started its service as soon as we installed it. We could access its main interface through any web browser and typing our computer’s hostname or IP address. A web page was then opened that allowed us to monitor Internet use in real time.

We used the buttons at the top of the program’s interface to make a variety of configurations, including sending of automatic e-mails depending on specified alerts. That was a handy feature because it could let us know immediately when someone tried to attack our system or computer. We even used the program to block network users from accessing certain websites.

The history section gave us a list of users and the websites they accessed, and the software enabled us to adjust the time it took before the log was displayed.

We improved our ability to block malware by blocking domains that phishing websites are known to use. The program can also be used to block programs that use DNS.
