Networking SmartFriends: Is port forwarding intrinsically a bad idea (as compared to using Tailscale Funnel) from a security perspective if I want to expose, say, a Plex server running on my NAS to the outside world?
That could have benefits, for example, if you're concerned about a DDoS attack on that service taking your home internet out, you may be able to work around it like this. But it won't mitigate a gaping hole in the underlying service which you're still exposing.
It could also have drawbacks, like limited bandwidth and higher latency, which would make it highly unsuitable for something like a game server.
