WebProxy and other HTTP filters have enjoyed great popularity for many years – probably because they are comparatively simple to use. The design of the NxFilter user interface can also be customized. For example, companies can use NxFilter to generate their own cloud filter service for paid users. Basically, the developers grant their users extensive rights. Companies, public institutions, and private persons can use the tool. NxFilter is available under a freeware license. Figure 1 illustrates the differences between unfiltered and filtered DNS queries.įigure 1: Comparison of unfiltered (top) and filtered (bottom) DNS traffic. Ideally, the cache provides the responses, which results in a significant reduction of network traffic. If you operate a local DNS filter, the local DNS server serves the queries. Assuming a corporate network uses the Internet provider's DNS servers, the DNS queries have to be sent to these servers, and the network clients have to wait for a response. The reason for the performance gain is the local cache that NxFilter uses and manages for DNS lookups. The news gets better: Experience reports indicate that the use of NxFilter has a positive effect on the Internet connection of all the network clients. Because the DNS protocol is used, the data traffic does not have to pass through a special filter – thus eliminating latency problems. In essence, NxFilter is a forwarding DNS server with a filter function. NxFilter is a freeware DNS filter that can compete with commercial products in terms of functionality and performance. This limitation can be solved with the help of a DNS filter, which can monitor all the traffic, regardless of the protocol used to send or receive data. However, latency is not the only problem: Proxy servers primarily specialize in filtering HTTP connections. These latency problems grow with the number of users. The use of such filters, often employing the Squid proxy server and similar tools, leads in practice to serious latency problems on the network because the proxy server analyzes and filters the web traffic and thus becomes a bottleneck. Thanks.Web filters that are based on the HTTP proxy server principle are part of the standard toolkit for protecting corporate networks. We are always interested in finding out how NxFilter performs out there. And glad to talk to one of our paid users on Reddit. Also a valid scenario for a company having multiple branch offices.Īnyway I thought you are looking for such kind of things since you mention a cloud filtering provider. So they can share one license between multiple schools. In that case, each school can see the private IPs behind their router and they can have different policies based on those private IPs. One of our customers runs NxCloud on cloud and installs several NxRelay agents in schools for filtering all of them. ![]() Maybe building a free service for limited number of users would be a good choice to us. However, these days I feel like we need to get involved into the business deeper to find out what they need. We have several customers running their own cloud filtering sites based on NxCloud but we don't know what happens on their side actually. And we are interested in building an OpenDNS like site. We will let our Globlist users to make multiple policies again. Maybe someday if we can come up with a prevetion method. That's why we don't rely on user classification. Some people classify everything into Ads or Porn. But we found some people are careless about domain classification. In old days, we allow people building their own repositories for Jahaslist update. I think you were talking about helping us with human classification. Too small money or too difficult for our users? Maybe you can make such kind of Youtube video and we give you a free license for Jahaslist in return. How about making Youtube video about your LDAP setup with NxFilter? At the moment we have 900 USD prize money event going on for Youtube video creation. If you are a school user it might get cheaper as we are discussing on introducing Educational License option for Jahaslist. Do you think it's expensive? I thought we are the cheapest in the market and we don't have plan for increasing the price for next several years. So you are already a paid user for NxFilter. So you can block Porn, Malware, Ads by Globlist and block other domains using custom categories. You know they can build their custom DB and share it between them with NxFilter. We were thinking of 3 or 5 policies for Globlist but 20 policies are too many for free users. We do reseller business and if we give too many free options they don't like it. Our problem is that we can't satisfy everybody. ![]()
