Swisscom Centro Business connected, with fixed IP.
One NAS wired to the centro Business with IP 192.168.1.6
One computer, used as server, wired to the Centro Business with IP 192.168.1.32
I configured the port forwarding, ports 22 / 80 443, from Centro Business to server IP 192.168.1.32
When I try to connect from "Internet" (with 4G mobile phone or other connection point as free wifi), I am correctly redirect to the server.
When it is wired to the Centro Business with a computer, I can access to the server directly with the IP (192.168.1.32) or by the public IP, because of the port forwarding.
BUT, when the computer is connected to the Centro Business throw WIFI, it can connect directly to the server by its IP (192.168.1.32) but not from the public IP.
I try many many things, because there is many topics with similar difficulty, and my only conclusion is that we can not access a machine, with the port forwarding, by the public IP and when connected with WIFI.
Does someone have this issue and manage to fix that ?
