What are your thoughts on the alternative path the article talks about “…zeroconf, mDNS, or DNS-SD advertisements”?
So it depends. For example some legacy apple stuff had a bad DHCP implementation where it would try to hold onto an IP address it had before.
When there’s one DHCP server with a reserved ip it won’t assign that ip to the wrong device. (Unless you’re running some buggy software that takes your configuration as suggestions)
Where the advice to set it anyways comes from scenarios where that DHCP server goes down for long enough that everyone starts self assigning addresses. It’s a real hassle to find the correct system when that happens.
Avoiding spam filters and ISP blocks are a common issue with self hosted email.
Ideally you’ll have a mature domain, dkim configured and an IP that’s not blacklisted on a network that allows email traffic.
OVH offers pretty cheap email hosting if you just want a turn key solution.
Otherwise if you want your home lab to work this way you may need to configure something akin to a forward proxy on a VPS to act as a gateway for your homelab.
This could be achieved using wireguard and iptables. By routing the email traffic to your homelab.

If your lan devices only have a fe80, your clients are not receiving a proper router advertisement.
Which routes and firewall rules should I be checking?
Since the OPNsense device is getting a ipv6 address and is able to ping ipv6 devices on the internet.
It sounds like you don’t have ipv6 configured for the LAN. Try enabling “Assisted” mode.
Confirm the ipv6 addresses your clients in the LAN are being assigned an ipv6 address within the scope of what your ISP is assigning.
If you are check default routes and firewall rules.
If you aren’t, investigate “router advertisement”.
It’s been a few months, did it happen?
Have you tried scrubbing the plate?
Might need to add a cooler to the nozzle
What’s that about?
Yeah, it felt pretty bogus. It was for red hat 5. Glad that’s all in the past.
I’m not familiar with that exact exam. But mine had me write out man pages from memory.
Ethernet is so versatile. I’ve seen a lot of places where they use it for phone and intercom wiring.
Surprise surprise when your IT budget is perpetually anemic.
