Firewall/VLAN Project
🔧 Network Setup Project: Overcoming Challenges with VLANs and Firewall Configuration
This week, I embarked on a project to configure a robust network setup using pfSense as my firewall
solution. On Day 1, I installed pfSense on a USB and set it up on the firewall, running into some
initial challenges with getting internet traffic flowing properly from the modem. After putting the
modem in bridge mode and power cycling, I successfully set up a public IP on the pfSense router.
Day 2 was dedicated to preparing and configuring disabled VLANs, setting the stage for a more complex
setup.
🌐 Configuring VLANs and AP Setup On Day 3, I faced hurdles with VLAN configuration—specifically,
routing AP traffic through the firewall and assigning VLAN IPs to devices. Despite multiple attempts,
I couldn’t get DHCP to assign the correct IPs to devices connecting to the Wi-Fi. Eventually, I
realized the solution lay in purchasing an AP that supported multi-SSID, which allowed me to assign
VLAN tags based on SSID. Day 4 marked a milestone with a new AP setup, where I tagged ports on the
switch to handle multiple VLANs efficiently.
⚙️ Finalizing and Troubleshooting the Network
On Day 5, I created different Wi-Fi SSIDs to properly route traffic through designated VLANs.
Configuring firewall rules, DHCP servers, and DNS settings for each VLAN was essential for proper
internet connectivity. However, I ran into another DNS-related issue where devices could ping IPs but
not resolve domain names. After some troubleshooting, I resolved it by ensuring DNS servers were
assigned correctly to the DHCP servers and devices. Now, the network is running smoothly with all
VLANs properly configured and internet connectivity stable.
🔐 The Benefits of a Home Firewall Setup
Setting up a firewall solution at home offers significant
benefits, not only by enhancing the security of your network but also by improving overall network
performance and control. By configuring VLANs, assigning proper firewall rules, and managing traffic,
you gain a deeper understanding of how networks function and how to optimize them for both performance
and safety. A firewall provides an essential layer of protection against potential threats, helping
safeguard your personal data and devices from unauthorized access. Moreover, the skills and knowledge
gained from this hands-on setup translate into better problem-solving and troubleshooting abilities,
making you more equipped to handle complex network challenges in the future.
