Introduction In this post, I will show you how to use policy-based routing in Unifi to route specific traffic through a VPN client (I use Private Internet Access) on pfSense. This setup allows you to retain complete control of your devices and subnets via Unifi’s Network app while taking advantage of pfSense’s ability to host a VPN client. With this setup, I am getting my full ISP speeds on devices using a VPN for encryption. Depending on your hardware, you should be able to get full speeds as well. ...

#UPDATE 11/05/2022 Original post date: 2021-04-05 This update contains specific configuration options to use 4096 bit RSA keys, SHA256 Auth digest algorithm, and AES256 encryption. The original post used the default key length of 2048 from PIA, SHA1, and allowed for AES128. Throughout the post, I will tag updated information with #Update. Introduction This post aims to show you how to use pfSense within a Unifi network behind a Unifi Gateway [in my case, the gateway is the Unifi Dream Machine Pro (hereafter referred to as UDMP)]. I will explain my current network configuration including applicable subnets, VLANs, and wireless SSIDs needed to make this setup successful. The end goal is to be able to add a client on my Unifi network to a particular VLAN either by joining this client wirelessly to a particular SSID or by tagging the client’s physical port to that VLAN. This VLAN will be tied to a subnet that sends data through the pfSense machine which is acting as a VPN client (I use Private Internet Access). This method allows the UDMP to continue to act as the DHCP server for these clients while allowing pfSense to anonymize and encrypt the data of the clients in question. ...

Introduction This post will cover how to set up a Docker container of Cloudflared on your internal network to provide a private tunnel from Cloudflare to your internal resources. After setting up the Cloudflared tunnels, you will no longer need to expose ports 80 and 443. This post assumes you currently have a vibrant and functioning internal network with a reverse proxy (in my case, Nginx Proxy Manager) already configured. Additionally, this post assumes you have a Cloudflare account with the ability to modify DNS records for your domain(s). ...

Introduction In this previous post, I showed how to connect to a Unifi router with HTTPS, effectively ridding you of the tedious words, “Your connection is not private.” However, the method shown in that post directs your connection to an external DNS server (e.g., CloudFlare) in order to resolve your Unifi router. This adds some latency by requiring your traffic to flow out and in rather than staying local. Additionally, it requires opening some ports externally. While this is not necessarily bad, it certainly increases the risks and attack surface of your network. ...

Introduction For this post, I will show you how to setup Unraid to run AlienVault OSSIM as a VM. OSSIM is a powerful open-source SIEM that you can leverage on your network for free. I use OSSIM for network-wide vulnerability scanning and endpoint host intrusion detection. OSSIM’s integrated HIDS is a fork from OSSEC. Additionally, OSSIM integrates with Open Threat Exchange (OTX), which can be installed on Windows, Mac, and Linux endpoints and servers for an up-to-date, open-source vulnerability scanning tool. I deploy the OTX installer via my free Mosyle account (MDM for MacOS) and Intune (MDM for Windows). ...
