I spent the better part of my Friday night reinstalling my NAS server for homelab purposes. Through this experience, I found I wanted to capture what I learned and where I found answers for archiving purposes. I found many answers online that either didn’t work for me or called for a different type of implementation. I link some notable guides and threads in the reference section below.

Setup

Wireguard is pretty simple and straight forward to install on any unix system. If you have any questions or see a place were an update should be made, send me and email or contact me on keybase.

  • Create a jail Create jail conf. More information on creating and controlling jails can be found here
	wireguard_jail {
	    vnet;
	    devfs_ruleset = "10";
	}
  • Install Wireguard in jail
	pkg install wireguard
  • Generate Keys
	wg genkey | tee privatekey | wg pubkey > publickey
  • Update rc.conf
	# Enable Wireguard
	wireguard_enable="YES"
	wireguard_interfaces="wg0"
	
	#Enable FireWall
	firewall_enable="YES"
	firewall_type="open"
	
	gateway_enable="YES"
	natd_enable="YES"
	natd_interface="[INTERFACE NAME]"
	natd_flags="-dynamic -m"
  • Create wireguard server conf I created my file in /usr/local/etc/wireguard
	# wg0.conf
	[Interface]
	PrivateKey = [SERVER PRIVATE KEY]
	MTU = 1500
	Address = 172.16.1.1/24
	ListenPort = 51820
	
	[Peer]
	PublicKey = [CLIENT PUBLIC KEY]
	AllowedIPs = 172.16.1.5/32
  • Start wireguard
	service wireguard start
