Hallo,
I've a cluster with multiple containers.
Two of them are lamp with public ip configured.
The host have a public ip also.
If i NMAP the proxmox hosts from the VM I get those ports opened:
22/tcp open ssh OpenSSH 8.4p1 Debian 5+deb11u3 (protocol 2.0)
3128/tcp open http Proxmox Virtual Environment REST API 3.0
Actually the host's firewalls are set on drop incoming packets and there are no rules to accept packets from containers ips.
Is there a way to close all ports so if someone penetrate the public containers cannot try to pen the host?
If i block everything from the container to the host will there be any issue?
Thanks,
Giacomo.
