Restricting plugin dashboard access from outside of the OPNsense UI

[Vharry]

Hii,

I have a question regarding the security implications of accessing a mailtrail server (or similar plugin) dashboard from outside OPNsense UI for respective plugins e.g maltrail. like I briefed below:

Here's the scenario: I have configured (WAN IP and listening port) in my OPNsense firewall to allow access to a mailtrail server. now with populating IP address and listening port in URL of any web browser, am getting access to maltrail Dashboard (post Authentication with Credential)

My concern is:

1./ whether this setup poses any security risks, as anyone could potentially access the server by knowing the IP address and port.

2./ whether we can restrict any such (e.g. maltrail etc) Dashboard Access from Outside OPNsense UI.

3./ Also, I want to ask if I can integrate the mailtrail dashboard in the OPNsense dashboard? Is it possible?

I appreciate any insights or guidance you can provide on this matter. Thank you for your assistance.

Best,
Harry

What are you attempting to do?  Why would you want to access maltrail from outside of your network?

Is there a reason you're not using a VPN?
