This article discussed the Netgate 2100 VLAN capabilities. We’re not trunking in this article, we’re simply spinning of a single switch-port as a discrete port. Ie, we’ll have one of the 4 switch-ports on a different VLAN. This article “https://docs.netgate.com/pfsense/en/latest/solutions/netgate-2100/switch-overview.html” from Netgate is correct, but: VLAN 1 (the default) seems

This article discusses the process to Bridge the Ethernet switch with the SFP+ ports on the Netgate 7100 firewall appliance. The process is simple enough but there is amazingly little documentation available to help you through the process. As indicated in the title, we’re going to Bridge ports on the

In this article we’re going to walk through installing Docker on Ubuntu, starting a few Docker containers, and then running those containers behind a reverse proxy. When we’re done, you’ll have a load balance terminating SSL (TLS) connections with multiple Docker containers running the workload. This is how it will

This article discusses the pfSense Netgate VLAN Trunk configuration. We’re using the Netgate 7100 as the firewall appliance, and a TPLink T2500G-10TS (common and fairly generic) switch to form a Trunk between. We have a computer on each side of the Trunk, each in a different subnet. See the diagram

This article discusses my recent experiences with 4G/5G fail-over for a small business running a Netgate 3100 pfSense firewall appliance. The model of the Netgate firewall appliance isn’t important. If you’re using a USB device for the 4G/5G, then it’s the pfSense drivers that matter. The question is, which 4G/5G

This article shows how to implement a small Node.js application that pulls data from a local MySQL server. We’re doing this on a CentOS server but that’s not important – any Linux will do. But if you’re using Windows, the installation process will differ. yum install nodejs npm install mysql

Install Docker Visit “https://www.docker.com/products/docker-desktop” and download Docker installer. Start the installation process (you’ll need local admin privileges).

Sometimes we don’t want the public knowing the versions of Apache and PHP running on our servers. This article shows how to hide that information. We’re using CentOS 7 for this example but the only difference really is the location of the configuration file for the Vhosts. Hide the Apache

Windows 10 allows you to get into a situation where you can’t change your PIN? Worse, you can’t set a password. This article explains how to solve this strange situation. Our objective here is to set a password and change our PIN number. Just setting a password isn’t solving the

The modules that we use are specific to our needs. But these are the most commonly used from my recent history. This list is super generic and mostly to supplement my poor memory. These methods/modules rely on a previously completed db_nmap scan. So our targets are readily available from the
