Exposing Your First Public Kubernetes App: “Hello World” on mydomain.com

Thiago Crepaldi — Wed, 24 Jun 2026 19:13:26 +0000

Today, we are taking our private, enterprise-grade Kubernetes cluster and safely piercing the veil to the public internet. Building on our previous guides, we will deploy a standard Nginx-based “Hello World” application and configure our infrastructure so it is reachable at hello.mydomain.com with valid, public-trusted SSL certificates—all while keeping your cluster security intact. By the...

Deploying Vaultwarden into a Kubernetes with High Availability

Thiago Crepaldi — Wed, 24 Jun 2026 19:01:46 +0000

In an earlier post, we covered Deploying a Public Vaultwarden Instance on a Proxmox LXC Container Using HAProxy on pfSense. While that architecture served us well, running a critical service like a password manager on a single node introduces a single point of failure. This guide represents the evolution of that setup. We are deploying...

Troubleshooting “Failed” pfSense+ Upgrades on Netgate Hardware

Thiago Crepaldi — Sat, 04 Apr 2026 04:25:10 +0000

The Disk Space Wall Updating your firewall is usually a “set it and forget it” task, but if you’re running a high-performance appliance like the Netgate 6100, you might occasionally hit a wall. In my case, I triggered the update from 25.x to 26.03, the logs start rolling, and then—Failed. If your logs mention cloning...

Overriding external domains DNS Bind9’s Response Policy Zone on your pfSense

Thiago Crepaldi — Sat, 18 Mar 2023 05:15:52 +0000

On a previous post, we’ve discussed how to use Bind9 on your pfSense in a way that external names were forwarded to name servers while internal names were statically resolved by Bind. In this post, we are going to discuss how to override the IPs returned by external name servers with IPs of our choosing....

Configuring DHCP Dynamic Host registration on DNS Bind9 on your pfSense

Thiago Crepaldi — Sat, 18 Mar 2023 04:51:28 +0000

On a previous post, we’ve discussed how to use Bind9 on your pfSense in a way that external names were forwarded to other name servers and internal names were statically resolved. In this post, we are going to integrate pfSense’s DHCP Server and Bind9, so that when DHCP assigns an IP to a device, it...

Configuring DNS Bind9 on your pfSense

Thiago Crepaldi — Sat, 18 Mar 2023 04:11:48 +0000

If there is one annoying thing on pfSense that seems to be never fixed is its DNS Resolver service called Unbound. Release after release, the Netgate folks still struggle to identify and fix the random crashes, unexpected restarts and whatnot. In this post, we are going to install Bind9, a very solid DNS server, to...

Monitoring pfSense Server using Zabbix Agent

Thiago Crepaldi — Sat, 31 Dec 2022 18:40:29 +0000

From previous posts, we have deployed Zabbix Server on a Proxmox container. We also hardened the installation through Let’s Encrypt certificates for the web frontend and TLS encryption for the communication between Server and Agents/Proxies, after all, although encrypted Zabbix Server <-> Agent/Proxy communication with PSK or SSL certificates 🙂 In this post I will...

Accessing ISP equipment/Modem from local network

Thiago Crepaldi — Fri, 16 Dec 2022 21:12:25 +0000

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. Since the device is not connected to any port of your local network switch, and therefore, sit outside your your network, accessing...

Setting up VPN client on your pfSense using Private Internet Access (PIA) service with Kill switch

Thiago Crepaldi — Tue, 13 Dec 2022 04:06:57 +0000

Private Internet Access (aka PIA) provides a cheap VPN service that allows up to 10 simultaneous devices. Recently I have switched from Surfshark to PIA because although Surfshark allows unlimited devices, having multiple connections in the same device (pfSense router) doesn’t always work. The reason is that different connections to different countries can have the...

How to host multiple domains using HAProxy as reverse proxy on pfSense

Thiago Crepaldi — Mon, 17 Oct 2022 05:02:22 +0000

In previous posts it was discussed how to create a DMZ network and host a website from a isolated VLAN on your network. That is a powerful resource, but with the limitation of not being possible to use a friendly FQDN such as geekistheway.com or mydomain.com as the frontend for the websites. This post will...
