Hello Michiel!

 MH>> There are ways around that (VPN, forwarding-host, etc.), but
 MH>> those are workarounds where another IP is exposed to fidonet.
 MV> Needlessly complicated.

Agree, but sometimes needed, see below.

 MV> DDNS has been in use for decades and every
 MV> decent router these days can deal with that.

Correct.

 MH>> Or are you talking about Pvt nodes?
 MV> Nope, I am talking about regular nodes that can accept incoming calls.
 MV> Pvt nodes do not even need a globally routable address.

Correct.

I think John's problem is not, that he hasn't a static IP, his problem is probably, that he has no public IP. This happens quite often with ISPs using CGNAT. My home connection is like this and in my case, the provider does not change it, not even at a price tag.

So i assume we can agree to this: "To run fidonet as non-Pvt-node, one needs a public IP with 1 static port open".

Some VPN services offer public IPs (useful when struggling with CGNAT). Some of them offer only one open port that changes quite often. "Private Internet Access" (PIA) is one of them. Such setups will not work for operating a mailer. DDNS is no help here as the problem is the changing port. This constellation is seldom, i think.
