I started using pfsense like 8 month or so. I am using haproxy and ACME cert to access certain items on web like jellyfin and accounting for my business and nextcloud. I also use openVPN from pfsense.
I don’t have anything else.
Is there a way to know what ports are open from outside to any of VM running on my proxmox or standalone truenas?
I found this tool and I saw these options. I selected WAN as source and hostname is ip of one of my VM and port is 80 as I use main ip to access certain services.
How do I check any if there is port which is open from outside as there are 65535 possible port and don’t have time to check all. Or am I doing this all wrong.
