Open media vault server issue

[Staysail]

Hi all,

First time posting here and I am new to OPNsense. Thanks in advance for your help! I have AT&T giga internet with BGW320 RG and used BGW320 for router function without any issues. Then I decided to use OPNsense behind BGW320 with 'Passthrough' connection. I installed Proxmox in Beelink mini pc and created OPNsense VM. OPNsense works fine as a router with basic settings and all devices connected to it work fine after transition except OMV(Open Media Vault server). I use fixed ip 10.0.0.xx for OMV and I have this error: ERR_CONNECTION_REFUSED from my macbook pro when I try to login Web UI using 10.0.0.xx. When I use my windows 11 laptop I can login Web UI and access to shared folders in OMV but after a few min I get red 'Software Failuare.....' message on the Web UI and no access to shared folders. I tried a few tweaks in OPNsense settings in Firewall and Interfacesbut nothing has worked so far. Is there any important basic settings I need to follow to make this work? As I am a newbie to OPNsense your help will be greatly appreciated!

Is there any important basic settings I need to follow to make this work?

Software like OMV often has an option that defines which networks/subnets are allowed to connect to it.

Did you check if such a setting is available and correctly configured ?
