DNS filtering tool that blocks certain websites based on their IP address, LDAP or password authentication method to restrict the access of other users and prevent suspected malware attacks
NxFilter is a comprehensive software application for monitoring and examining the HTTP traffic in your network, as well as for restricting access to websites. Although it may seem easy to handle, the tool actually requires some experience with networking tools, since it's mostly designed for administrators and other IT specialists.No setup necessary, aside from Java
This is a Java-based app that doesn't need any other setup, as long as Java is installed on the PC. This means that you can store it anywhere on the hard disk to be able to work with NxFilter. An important aspect worth taking into account is that it does not write new entries to the Windows registry, so it doesn't increase the risk of OS stability issues.Get the DNS server up and running
By accessing the "Network and Sharing Center panel", you can choose the TCP / IP protocol to configure for using a specific DNS server address. Since the program is actually a forwarding DNS server, you can apply the exact method of setting up a DNS server for user systems.
However, you should keep in mind that NxFilter features a console interface for updating the required folders, which means that you have to be familiarized with switches. By downloading the additional libraries (specified on the website) and configuring the installed services afterward, you can finally get the DNS server up and running.Web interface with restricted sites
From this point on, NxFilter can be accessed from any web browser by visiting its dashboard in the local host. It displays two graphs with the traffic and block trend, giving you the possibility to block remote hosts based on IP addresses, LDAP or password authentication method, in order to prevent suspected malware attacks, for example.
You can get notifications about the user who tried to access blocked webpages, as well as create a list with as many users are necessary to associate them to IP addresses. Furthermore, it is possible to manage policy information, create a whitelist by domain, check out a list with known phishing websites, edit request details, as well as generate and study daily reports.Overall, a reliable DNS filtering tool
Considering all of the above, NxFilter proves to be a reliable DNS filtering application that enables you to monitor and restrict permissions for all Internet activity, as well as to detect and block malware or botnet activity by analyzing the DNS packet.
Faster and lighter
Traditionally we made a web-filter based on HTTP proxy server. There are many commercial products based on Squid proxy. But with this approach you might have a serious latency problem on your network. This is because your web traffic needs to go through one point in your network that is your web-filter and it becomes a bottle neck in your network. This latency problem gets bigger when you have bigger number of users. But there’s another approach. That’s DNS filtering and NxFilter is a dns-filter. It’s basically a forwarding DNS server with filtering ability. Since it uses light weight DNS protocol there’s no need to have your traffic going through anywhere. You get no latency problem with NxFilter.
Boosting up your Internet speed
Some users reported that after they installed NxFilter on their network their Internet speed improved greatly. This is because NxFilter keeps local cache for DNS lookup. Suppose in your network everybody uses Google public DNS server or your ISP DNS server. Their DNS queries need to be sent to these DNS servers on the Internet and your users need to wait for the response back from these servers. But if you have NxFilter in your network it keeps cache for the DNS response from its upstream DNS servers and reduces the network traffic greatly and your users don’t need to wait for the response from these DNS servers on the Internet.
Even though it’s faster and lighter than the traditional web-proxy based filtering, DNS filtering had its own limit in the past. It did not support user authentication. This is natural because DNS protocol doesn’t have authentication scheme. It was the biggest obstacle for a dns-filter to be employed in real-world enterprise environment.
However being a dns-filter, NxFilter provides 4 types of authentication methods for user identification.
With NxFilter you can differentiate users and apply different filtering policies.
NxFilter supports application control through its agents, NxLogon and NxClient. With this feature you can block UltraSurf, Tor, uTorrent, Skype, Minecraft and other applications you want to block.
There are many benefits only from a dns-filter but we had to give up several things if we want to go with a dns-filter so far. You can’t enforce safe-search and you can’t have keyword filtering against URL as it’s working on DNS level. But now NxFilter provides web-proxy filtering through its agents, NxLogon and NxClient. NxLogon and NxClient themselves are local web-proxy and they can do whatever a web-filter can do. Currently It supports safe-search enforcing and URL keyword filtering, IP host blocking.
One might think providing these web-proxy agents, NxFilter is not a light-weight filtering solution anymore. But it still is. These web-proxy agents are working as local web-proxy only for one user so it doesn’t cause any network performance issue.
When you deploy a web-filter in your network. The most tricky part would be forcing filtering on your users without too much hassle. If you go with a web-proxy based filtering product you need to setup all the browsers pointing your web-filter as their proxy server. To make things easier you can use so called ‘transparent proxy’ setup so that you don’t need to setup all the browsers one by one. But with the transparent proxy setup you have a problem for HTTPS filtering as it is breaking the browser restriction for ‘man in the middle attack’. Your browser will not send HTTPS request to your proxy if you try to redirect the traffic transparently. And plus this transparent proxy setup is quite challenging even for a seasoned systems engineer.
If you go with a dns-filter you are free from all these hassles. You just need to setup your DHCP server using NxFilter as the DNS server for its clients. Then your users will use NxFilter as their DNS server and they will be under filtering. Forcing filtering to users is also possible. You can block outgoing 53 port on UDP and TCP except from NxFilter. Now NxFilter becomes the only DNS server your users can use. It’s already transparent and doesn’t cause ‘man in the middle attack’ problem with HTTPS.
It’s not just for HTTP traffic
If it’s a web-proxy based filtering product you only can filter HTTP and HTTPS but with DNS filtering you can filter almost every protocols including HTTP, HTTPS, FTP, P2P as long as they use DNS.
NxFilter is also capable of detecting malware and botnet based on DNS packet inspection. It is possible because NxFilter is working on DNS level.

FreewareFiles Editor's Review
Note: When you initially start NxFilter, the Admin password is "admin".
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.
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.
NxFilter is a DNS filtering software. You can filter and monitor Internet activity in your network with NxFilter. It is also capable of discovering and blocking botnet and malware based on DNS packet inspection. By accessing the Network and Sharing Center panel, you have the chance to choose which TCP / IP protocol will be configured in order to use a specific DNS server address. Since the program is in fact a forwarding DNS server, you can use the exact method of setting up a DNS server for user systems. In addition, it lets you use the command prompt utility because updating the required folders can be done simply using command shortcuts. Then, by downloading the additional libraries (specified on the site) and configuring the installed services, you have the chance to use your created DNS server. A DNS server, which is also known as Domain Name System, easily translates domain names to the numerical IP addresses so you can find computer services. So, by using NxFilter one can simply block not only the Internet connection to specific domain names or websites, but also detect and prevent malware attacks. NxFilter is capable of discovering botnet and malware based on DNS packet inspection. It is possible because NxFilter is working on DNS level. After configuring all the settings, you can start the program and see all the accessed webpages. The main window shows comprehensive info about each blocked website and the user who tried to access that specific webpage. What's more, you can add as many users as you would like by associating them to several IP addresses. This way, if a user will access a blocked websites, you will get immediately notified. However, if you are not satisfied considering the limitation rules, NxFilter keeps DNS query or blocks history for a certain amount of days defined in the proper panel. AD integration and single sign-on while it is a freeware. Also capable of blocking HTTPS as it is working on DNS level. Providing a remote filtering client and dynamic IP updater. By employing a light weight protocol it can handle several thousands users easily. NxFilter works nicely and offers flexible filtering options. however you should have some basic network knowledge to properly install and configure all options.NxFilter highlights and features:
