![]() I want to filter web content at the DNS level. So I run pfSense (10.127.1.254) as the main firewall/router and on a separate device I have NxFilter (10.127.1.240) to filter the DNS content which works great. Tradues em contexto de 'integrao e o funcionamento' en portugus-ingls da Reverso Context : Anlise do impacto da integrao e o funcionamento de um servio instantneo de emisso de cartes em agncias bancrias. Protocol Source Port Destination Port Gateway Description If i change the DNS address on device level to the IP of any other DNS Server it auto-bypass the NxFilter which I understand it will do, thus have I implemented firewall rules to block access to any other dns server, firewall rules as follow. IPv4 TCP/UDP * * * 53 (DNS) * Block All other DNS Servers Then I made the primary DNS Server on pfSense to be 10.127.1.240(which is my nxFilter) and the secondary DNS Server 1.1.1.1 and on NxFilter I have made my upstream DNS Server 10.127.1.254 which points back to pfSense. Translations in context of 'caso, voc pode fazer' in Portuguese-English from Reverso Context: Neste caso, voc pode fazer uma geleia maravilhosa desta fruta. Then you can filter the whitelist with nxFilter.I have a setup consisting of a physical server ( server) running Ubuntu, on that, a Windows 2016 Server running as a VM serves as a Domain Controller ( dc). and aims to provide an easy and fast way to navigate directories, with thousands of high-resolution photos. I then have another physical machine acting as my router running pfsense ( router). The router is acting as the DHCP server, although I have heard that it's prefered to let dc handle it. Mostly because it's handy to log into the webadmin of pfSense to fix things instead of using Remote Desktop to login to dc and also since dc is a VM and depending on a reboot of its host server might not be up when I need it to. For instance server would have issues asking for a DHCP lease from dc if it hadn't started the VM of dc first. It allows it (and me) to easily add specific hostnames for an ip, reroute stuff etc. Since I have three children in the house it also allows me to apply basic DNS filtering based "protection" against certain "known things" by running BlockerNG and Snort (although I still need more time to configure this). I had set the DHCP Server on router to give the ip of dc as the first DNS server and then dc uses router as a forwarding DNS for things outside my own network. The Active Directory on the domain works fine, internal hostnames work fine and external hosts are resolved correctly.īut, now I was thinking about addin NxFilter to the mix. My idea is to be able to do more fine grained DNS filtering with that for the kids based on their Domain Users. I think that being able to " stream" it would be a valuable addition to NxFilter.īy enabling log forwarding to a SIEM, it would empower admins and organizations to leverage the full potential of both NxFilter and their SIEM solution, enhancing their security posture and incident response capabilities.But, I'm starting to feel that it might be a bit "to many" DNS's involved in my setup and that I might not be doing it in the "correct" way. Has anyone in the community managed to do this? Any feedback would be greatly appreciated. ![]() I could not find where, on how (i.e., on what format) does NxFilter stores the logs we see in /logging,request.jsp It offers many features like Active Directory integration, User or Group. One possible solution is to install an agent on the server (cloud SIEM provide those) to read the content of a file and send it to the HTTP collector of the SIEM.

So those two articles are not applicable for us. ![]() In my efforts of exploring the documentation and the WebUI, I found those two articles:Ĭontrary to internally-hosted SIEMs (which often have a syslog collector), cloud SIEMs rely on HTTP collectors, and the preferable event format is JSON. This means that, in my environment and context, admins and security analysts would need to connect to the NxFilter WebUI to investigate events instead of being able to see them from the SIEM. ![]() While NxFilter is excellent, I've been struggling to find a way to send logs to a "cloud" (SaaS) SIEM. By aggregating logs from various sources, admins and security analysts can have a global view of events, as well as being able to detect production & security incidents. Having a SIEM in an enterprise environment enables centralized log management, real-time monitoring, and advanced analytics.
