Hi, I have my mailcow dockerized server for like a year now.
I had my MC VM in a proxmox server but I had a mac from hetzner and had it exposed to the internet.
Now I did some changes to add the extra IPs that I had into pfsense for protection, so I added the static IP as virtual IP and I did NAT rules for the ports stated here: https://docs.mailcow.email/prerequisite/prerequisite-system/#firewall-ports
The mailserver works! I can send/receive mails but I can’t access the web UI.
I found the /optc/mailcow.conf the bind IP, i changed it from the true IP to the internal that I have assigned to my VM, restarted the VM but still can’t access the UI.
Server details: Ubuntu 22.04.3 cloud image vm from template.
Host: Proxmox 8.1.3
Updated: Yes, full updated in both linux and mailcow containers.
NAT: Yes, all ports listed here https://docs.mailcow.email/prerequisite/prerequisite-system/#firewall-ports are open
Any suggestions on how to fix that?
The error I see is:
This site can’t be reached
mail.domain refused to connect.
