<h2 id=pfsense>pfSense</h2> <h2 id=pfsense>pfSense</h2>
<p>I figured this would be a good opportunity to try <a href=https://en.wikipedia.org/wiki/PfSense>pfSense</a>. I&rsquo;ve heard nothing but positive things about pfSense and the fact it&rsquo;s been around since 2004, based on FreeBSD, and written in PHP gave me the impression that it would be relatively stable (and I&rsquo;d expect nothing less because it has an important job to do!). pfSense can be run on many different machines, and there are even some <a href=https://www.netgate.com/appliances>officially supported appliances</a>. Since I already have a machine running Proxmox, why not just run it in a VM? It&rsquo;d allow for automatic snapshotting of the machine. There is a good <a href="https://www.youtube.com/watch?v=hdoBQNI_Ab8">video</a> on this by Techno Tim. Tim has a lot of good videos, and this one is about virtualizing pfSense.</p> <p>I figured this would be a good opportunity to try <a href=https://en.wikipedia.org/wiki/PfSense>pfSense</a>.

<p>I had initially made the assumption that in order to build a router, you would need more than a single NIC (or a dual-port NIC) in order to support both WAN and LAN. This is simply <a href="https://en.wikipedia.org/wiki/Router_on_a_stick#:~:text=In%20computing%2C%20a%20router%20on,switch%20via%20a%20single%20cable.">not the case</a>, because VLANs are awesome! In order to create a router, all you need is a single port NIC and a network switch that supports VLANs (also marketed as a managed switch). I picked up the Netgear GS308E because it has both a sufficient amount of ports for my needs, and it supports VLANs. It also has a nice sturdy metal frame which was a pleasant surprise.</p> <p>I had initially made the assumption that in order to build a router, you would need more than a single NIC (or a dual-port NIC) in order to support both WAN and LAN.

<p>After setting up this Netgear switch, it shoud be possible to access the web interface at <a href=http://192.168.0.239>http://192.168.0.239</a>. It may be at a different address. To find the address, try checking your DHCP leases in your router interface (if you plugged it into an existing router). I realized I was unable to access this interface because I was on a different subnet, so I set my machine&rsquo;s address to <code>192.168.0.22</code> in order to temporarily setup this switch. I assigned a static ip address to the switch (in <code>System > Switch Information</code>) so that it was in the same subnet as the rest of my network.</p> <p>After setting up this Netgear switch, it shoud be possible to access the web interface at <a href=http://192.168.0.239>http://192.168.0.239</a>.
