If you can't install it still then send me an email. I think in your home-router you can set NxFilter as your DNS easily. To read something about DHCP and DNS setup. If you have difficulties in client setup then I recommend you Maybe some other applications as long as they use DNS. Of course you can block https sites as well. You can have authentication with IP or password.Īnd you also can integrate it into Active Directory. Then you get the login prompt in your browser.Īnd the initial password for admin is 'admin'. You need to have Java 1.6 or higher installed first.Īfter you start NxFilter then click the icon to web-admin. One for starting NxFilter one for web-admin. Just click the exe file and you get several icons. There's a Windows installer for people not familiar with Linux.Īnd you can make it Windows service as well. If you are not familiar with Linux environment then you can try windows version of NxFilter. I thought I made it very easy to install NxFilter.īut you said that you have some difficulties in using it.Ĭan you tell me on what part you have the problem? This is Jinhee the developer of NxFilter. I cannot figure out from your request whom you're trying to filter, but a better method would be enforcing good behavior. I would not suggest any of this for newbie Linux users. This blocks HTTPS connections to one of Facebook's servers. You'd need to identify all the possible server addresses for each site, then write iptables rules like this: Many sites with heavy traffic loads have multiple servers listening on multiple IP addresses. If you're curious, do a search for "SSLBump".Īt one client site where I manage filtering we use iptables firewalling rules to block remote HTTPS sites. With this app, you dont need to go through NxFitlers login-page when its filtering your network with user. Squid 3.2 has some clever solutions for this problem, but they are not easy to implement. This is a single sign-on agent for NxFilter. Putting a filter between clients and remote sites using SSL will generate repeated complaints by the client's browser that you are being subjected to a "man-in-the-middle" attack since the filter will disrupt the encrypted transaction between the browser and the server. You can write all sorts of rules that allow or deny connections to remote sites based on IP, domain name, or text in the URL. But if you can manage a PC network then you shouldn't have much trouble, and what you'll get for your efforts is one of the most capable and configurable free web filters around.First, your best choice for a filter is Squid (). NxFilter is an enterprise-level web filter, and setting it up needs some network experience, and a little time. If the default site blocking isn't enough, NxFilter supports adding domains manually, or grabbing the blacklist from You get a stack of configuration options, there's even support for authenticating users via LDAP and Active Directory (as well as password and IP address), all while delivering great performance (the developer claims NxFilter can handle "several thousands of users easily"). And you're even able to assign policies based on a time range, so for example an office might have a very loose policy at lunchtime, but something much more restrictive for the rest of the day. These policies can be applied to individual network users, or groups of users. If you need more control, it's possible to create NxFilter policies which block sites by category (75 in total), or only allow access to particular site categories - or all internet access - for a certain amount of time a day. A browser-based console displays stats on web traffic, blocked domains and more, as well as logging every site you've accessed. Get NxFilter running on one PC, though, and it brings benefits right away, blocking known phishing sites and using packet inspection to detect some malware. It's still not difficult - if you know how to configure your system to use a custom DNS server then you won't have much trouble - but you will have a little work to do. NxFilter isn't for network beginners, it won't fully set up everything itself, and even the web tutorial doesn't walk you through every detail. You'll first need to install and configure the program, of course, and that can take a little effort. It's also possible to limit access by user and time, and one NxFilter installation can protect your entire network. NxFilter is a powerful Java-based web filter which controls access to web sites based on their domain names.
