Local Firewall

PMG does not currently ship any built-in firewall configuration script/ui/tooling.

I'd recommend setting up a local nftables.conf file (it's quite simple to handle and there's tons of examples on the internet)

The needed ports for services are documented in the reference documentation:
https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#firewall_settings

Else there's also a large number of toolings available in the Debian repositories (ufw, and ferm come to my mind, but there's may others as well)

I hope this helps!
 
I'm trying to setup Bacula for backing up. This is the last computer I need to get working. I need ports 9101, 9102 and 9103. These ports are being block at the Proxmox level because nmap reports them as closed.
