I have set up a Debian-based virtual machine in proxmox to host my docker containers. The containers are up an running, but i am not able to forward some ports from this VM to the internet.
the VM is also running a simple web server, that I can access from my local network without any issues on ports 80 and 443. however when i try to
however, if i run nmap from inside the VM the ports 80 and 443 show up correctly:
this makes me think the problem somehow is in proxmox. firewall is disabled for the VM. previously the docker containers (with the same ports) where running on a different VM without any issues.
any idea where could be the problem?

my host the ports 80 and 443 (and bunch of others that are used by some containers) are not visible. consequently i am not able to forward them to WAN.
Code:
$ nmap 192.168.50.10 -Pn
