I have a server in my home and use it normally with my custom router setup. but I want to do the same in other place where I’m not allowed to modify the main router
How can I expose a port to internet in this case?
P.D: I want to use my laptop as a portable server; connect it to my mobile hotspot and go, I think that the solution will be the same for both cases
Thanks in advance
Use an outbound tunnel like the others recommended already.
For curiosity: a mobile hotspot in my mind is a device connecting to Internet via mobile data (LTE, 5G etc) and offering a WLAN. In this case this is your router. But mobile provider often offer no public reachability at all - in which case you are back to the tunnel.
