Have anyone tried sending data from HF to UF? I know it's a stupid question. 😉 And I know it's not going to work.
If someone has tried it before intentionally or by mistake, then I'm curious to know what happens in this scenario, what error HF will throw, and what error UF will throw.
It's not a stupid question. And I can imagine a relatively valid scenario when you would like to have a HF forwarding via UF. Theoretically, I don't see why UF shouldn't pass such traffic but I've never tested it and it may turn out that it doesn't 🙂
Just try and see. What is the worst that can happen? It will not destroy your servers 😉
