>* My IPv4 address with FiOS changes frequently. I use an outside dynamic DNS provider that the FiOS router supports natively so I can always get back to my home network.* I handle this exclusively with WireGuard or Nebula now, though I'm sure other stuff like ZeroTier would work too. At worst a $5 VPS is enough to act as a lighthouse/relay, although as it happens for one of my virtual networks I do have a fixed IP to work with. But everything else can be whatever, completely dynamic, and all the tunnels stay up fine 24/7/365 and traffic can be routed through them as I wish and extremely minimal exposure. On my own sites I use OPNsense to mix and match whole VLANs. If one explicitly wants to run services to the general world from home that's of course no good, but if it's all private I think modern point to point tunnels or high level dynamic meshes are an excellent option now, and can be fully self-hosted super easily. It's very exciting how fast, reliable and powerful completely FOSS options are nowadays.
