Is it possible to forward port 80 on a home modem?

Question

network hardware

There is a Xiaomi MiWiFi R3 modem. I can’t forward port 80, is it possible to do this, or are ports 80 on home modems occupied by their web muzzle?
All other ports are forwarded normally, the same 443, but 80 does not want to - is this a feature of all home routers?

Answer 1

I suspect that in the router settings there is an item something like "show web ui on the WAN interface". So it needs to be turned off. This is useful for security and will free the port.

Answer 2

First, the face is thrown to another port, then you can forward

Answer 3

what for?
Well, that is, keeping a public service at home is an extremely dubious idea. and not a common one, you can and should hang it on a non-standard external port (and where you forward it is up to you). Are you sure that you are doing what you need and that you need exactly what you are doing?
