To expand:
- We're already leery of questions about home routers... they could conceivably be on-topic if it's a sysadmin trying to make remote access work, but few (if any) of the home router questions we get make the cut.
- Many of us (e.g. a certain cat-head-avatar person) are dubious about things like DD-WRT: repurposed home hardware used professionally. I think DD-WRT and its ilk are also borderline: they can be used professionally (I use it at work), but the hobbyist nature shows up in lack of support, iffy documentation, and so on.
- So by the time you're talking about general-purpose, hobbyist systems like the Pi, I think you're way over the line into tinkering for fun, not professional. Again, the lack of support, documentation, examples of realistic professional "server" use are the distinguishing features.
