Most Internet Service Providers (ISP) install devices in our houses, such as a cable/DSL modems or a ONT/ONU for optical, which have a web interfaces on a private IP address of its own.

DMZ (aka Demilitarized Zone) network as defined by Wikipedia “is a physical or logical subnetwork that contains and exposes an organization’s external-facing services to an untrusted, usually larger, network such as the Internet”. The purpose is to add an additional layer of security by separating what is exposed a public service in the DMZ, while the rest of…
For those who followed my previous post on how to configure a VPN client on pfSense, one cool application for it is to route only specific websites through the VPN while the rest of the traffic goes through the default ISP gateway, as usual. That is interesting when you want to use an IP from…
From time to time, I need to reference the use of a IP alias called RFC1918 to separate traffic from local network from other (aka “Internet”) traffic. RFC 1918 was published to “Address Allocation for Private Internets”, which is our local network. There is nobody on internet using any IP in the range described by…
On pfSense’s documentation own words, “the basic idea of traffic shaping is raising and lowering the priorities of packets or keeping them under a certain speed. This concept seems simple, however, the number of ways in which this concept can be applied is vast.” pfSense supports “Traffic shaper” and “Limiter” (and they can be used…
By default, pings are not allowed and actually not recommended. Bu during a network debugging, it can be quite handy. In order to allow ping incoming on the pfSense WAN port, go to Firewall >> Rules >> WAN page and create a new rule by clicking on Add button (down arrow icon) and do as…
In this article I’m going to show how to authenticate users on your pfSense using LDAP server powered by Synology DSM. The steps will include SSL encryption based on Let’s Encrypt certificates. You need to issue Let’s Encrypt SSL certificates, configure SSL certificates on your pfSense, and finally configure SSL certificates on your Synology that…
This post is complementary to a previous POST protecting your network from malicious DNS. Here we are going to leverage a recent addition to pfBlockerNG: a brand new DoH feed! What is the big deal in allowing DNS over HTTPS (aka DoH) on your network?! Well, users can bypass the DNS over TLS of your…

DNS over TLS is not supported…
