- WireGuard is supported in pfsense but does not have an “Easy Setup” option for using a privacy VPN
- WireGuard does require that you open ports and have a public IP
- psense does support support Dynamic DNS
Services — Dynamic DNS | pfSense Documentation - pfsense does support policy routing allowing you to choose where the data routes, either VPN or WAN, etc…
- Synology is much more turnkey easy for setting up things, TrueNAS is much more to configure for sharing but does support tools such as Syncthing
- The data on TrueNAS can be replicated to another TrueNAS
- UniFi AP’s and Switches use the UniFi controller software do not require registration with Ubiquiti
Here are some videos where I go over some firewall rules for pfsense for a basic home setup & UniFi VLAN setup
I also have a video on policy routing with a privacy VPN
You can also find lots of other videos on TrueNAS & Syncthing on my channel.
