Configure IPv6 for Proxmox Host via Slaac

The Proxmox server running at home only has an IPv4 statically assigned to it. Since I’ve been trying to get all my connected devices at home to get IPv6 assigned, I figured I should try with this Proxmox server next.

Nginx Redirect One Path to Another

Nginx is probably my favorite web server up to this moment, and it runs and serves websites on all of my servers. I should say, I also like Apache web server too, but not as much as Nginx.

How to configure IPv6 on FreeBSD via SLAAC

I recently got IPv6 running at home, with most devices including my iPhone happily get an IPv6 assigned.

The way I have it setup on my router, running OPNsense, is to set the “Router Advertisements” to “Unmanaged” with DHCPv6 disabled. “Unmanaged” for SLAAC (A flag), and SLAAC stands for Stateless Address Autoconfiguration....
