 Base setup was done following this article: https://homenetworkguy.com/how-to/set-up-a-fully-functioning-home-network-using-opnsense/#unbound-dns-general 

 Dynamic DNS Setup is here: https://oga.atlassian.net/wiki/spaces/~311198967/pages/234848257/OpnSense+DynDNS+Setup 

 It’s a good guide on how to add a new VLAN and associated interface.

 Web UI Access 

 The UI is available on the LAN interface at: https://192.168.1.1 

 The LAN interface is LAN3 (em3), which is the bottom port on the 4-port NIC. 

 Locked out of Web GUI 

 If you ever get locked out of the web interface, open an ssh session to the router, and issue this: 

 configctl webgui restart renew

 Speed Test 

 Installed speed test plugin from here: https://github.com/mimugmail/opn-repo 

 This requires opening an SSH session to the router, and running this line (taken from the GitHub page): 

 fetch -o /usr/local/etc/pkg/repos/mimugmail.conf https://www.routerperformance.net/mimugmail.conf

pkg update 

 Once installed, open OpnSense and navigate to available plugins. 

 Locate the added plugin called: os-speedtest-community, and install it.
