Everytime when installing a pfSense router from scratch, I seem to re-learn a few of the below quirks. So it was finally time to document them (:
Quite a few of my pfSense configurations are just doing routing between various networks, should not provide DHCP leases and do not always need or have a WAN connected (i.e. they are LAN-only).

This is actually the WireGuard package you can install on pfSense CE 2.5.2 and higher: [Wayback/Archive] rcmcdonald91/pfSense-pkg-WireGuard: This is a port of the original WireGuard UI bits as implemented by Netgate in pfSense 2.5.0 to a package suitable for rapid iteration and more frequent updating on future releases of pfSense.
Note that the source code mentions a lot of web-technologies but that is because the majority of the code is the pfSense plugin. Underneath it pulls the actual build from [Wayback/Archive] git.zx2c4.com/wireguard-freebsd/snapshot which is almost exclusively C code.
Like WireGuardNT on Windows, it uses a high performance kernel mode driver.
Some more links on it:

Since GL.iNET does not support site-to-site “Peer to Peer” OpenVPN (only “Remote Access” is supported) which is needed to route to/from the networks on both sides of the connection. the below did fail.
Below was what I hoped to function.
Some links that should get me started (though my situation is a tad more difficult, see below):

For my link archive a router I bought a few years back: [Wayback/Archive] GL-SFT1200 Secure Wi-Fi Router On The Go – AC1200 Dual-Band Gigabit Wireless Internet Router | IPv6 | USB 2.0 | MU-MIMO | 128MB RAM | Repeater Bridge | Access Point-M Mode: Amazon.de: Computer & Accessories
I needed it because from prior experience, I knew GL.iNEt can support a special Wireless Repeater mode where it still functions as a router (hiding the LAN/WLAN behind NAT)
Two physical drawbacks likely due to the portable nature:
the plastic RJ45 ports are slightly too wide which means that these keep falling out [Wayback/Archive] Inline® Dust cover, for RJ45 socket, color: green, 100pcs. Pack: Amazon.de: Electronics & PhotoOne firmware drawback: it shipped with v3.212 for which I could not find release notes. Luckily the firmware v3.215 I upgraded to had: [Wayback/Archive] Firmware v3.215 is released – Technical Support – GL.iNet.
Links to product and manuals (the paper manual are just two thin sheets, but the on-line documentation is OK; I was surprised WireGuard and Tor were supported!):

I have been contemplating on pfSense hardware as there has been a large shortage on that market especially for having more than 2 ports (similar to for instance Mikrotik PoE router unavailability).
If by now I have not found any, I might want to revisit [Wayback/Archive] Gowin R86S mini PC offers 2.5GbE and 10GbE networking for $310 and up – CNX Software has 3 RJ45 ports and 2 SFP+ cages.
They found it via this 4 page review:

I wasn’t aware that [Wayback/Archive] [OpenWrt Wiki] MikroTik was available. Many devices are incomplete in support, but it is good to know there is an alternative to the buggy scripting interface of RouterOS.
For the hEX series, support seems good enough to give it a try this summer, but I need to figure out of the hEX PoE RB960PGS is supported. I have good hopes as other models of the RB9* series are.
A few warnings from the below links:
These hEX related models are supported on the web-site (which also explains major differences with Fast Ethernet (100 Mbit/s) and Gigabit Ethernet (1 Gbit/s) models:

I wonder how well [Wayback/Archive] H3/H2 Net Card – ODROID is supported by pfSense. It is an M.2 based PCIe network card that adds 4 ethernet ports of 2.5 gigabit each to an ODROID H2 or H3 series (so you have 6 ports total), ideal for some hefty router.
Pictures (from the above link) of the board, cases and mainboard below.
But first: Realtek NICs is not vendor supported on FreeBSD (which pfSense and OPNsense are based on).

Two interesting posts on fast network routing:
… I also ran into weird DNS slow-downs, which I didn’t fully diagnose. In Wireshark, it looked like my machine sent 2 DNS queries but received only 1 DNS result, and then waited for a timeout.
… Since I last used MikroTik in 2014 the software seems to have barely changed. I wish they finally implemented some table-stakes features like DNS resolution for DHCP hostnames

Reminder: check reviews for this little device: [Wayback/Archive] Compact fanless firewall appliance offers 6x 2.5GbE ports for $230 and up – CNX Software
If referred to:
(which for EU customers went up from USD ~230 to USD ~270 the day CNX published; this might have to do with VAT and import duties [W/A])
