I dont like my ISP but it does let me use whatever ports I want for self hosting. Comcast does not without extra fees and even then its very expensive.
I used to port forward, but I have stopped doing it. I don't want to have open ports on the same IP that I use for internet browsing.
I have my local server connected, via WireGuard, to a cheap nearby VPS. All my services are exposed from that VPS.
This configuration also offers full portability to my home server, allowing me to switch to any ISP, or even move to mobile data, if I have to.
For applications that require even lower latency, like remote gaming, I use Tailscale, which can traverse the NATs and create direct connections between the devices.
I just have a firewall and call it a day. No more extra services, no extra money, and as long as 80/443 are good externally and a couple of others im good. Its a small server, I dont even have ssh open outside the network.
I don't even bother with local ports anymore. It's just too much hassle when I switch providers, email services all seem to universally sinkhole anything originating from a residential IP even if I am able to convince them to unblock 25/TCP, and I refuse to pay extra for a static IP or upsell to business class at a massive price increase.
My ISP, while otherwise fine, still has not rolled out IPv6 yet and the DHCPv4 lease duration is short and will randomly assign a different IP rather than renewing the lease on the existing one. I don't like relying on dynamic DNS or relying on running a daemon to update my public DNS records when my public IP changes. Been there, done that, and bought a crappy t-shirt at the gift shop.
I've had a VPS for close to 10 years now that is my main frontend and, through some VPN and routing trickery, allows me to have my email server on-prem but use the VPS for all inbound and outbound communication. A side effect benefit of this setup is I can run my email server from literally anywhere and from anything with an internet connection. I've got a copy of my email stack on a Pi Zero clone that stays in sync with my main one. During long power outages, I can start that up and run it from a hotspot with a power bank running it for almost 2 days (or indefinitely when I'm also charging the power bank from a solar panel lol).
