It turns out that my caring ISP really has a free firewall service
which is enabled by default.
I asked my ISP to disable it completely and now everything is OK.
Thank you!

The problem is that only port 80 seems to be open from the outside.
I used several online port scanners to check this.
All of them tell:
port 80 OPEN
port 443 CLOSED
Could it be blocked by your ISP? Do you receive packets on your external
interface at all when you test port 443?
