Logging of the firewall activity

Palou · 9. Januar 2020

Hello,

I have completed the installation and configuration of OMV 4 on my Raspberry PI 4, including the firewall (see attachment) with the last rule to DROP everything that is not explicitly allowed.

My problem is that with this last rule, I cannot access the NAS from my LAN or from Internet, when I delete this last rule, I can access the NAS from my LAN and from Internet and everything is working properly.

My question is, how do I log firewall activity in detail to debug my problem?

Does anyone detect an error in the configuration of my Firewall?

Thanks

When you specify source ports in an input firewall rule it is almost always a mistake. Those should be destination ports instead.

I don't understand what you are trying to accomplish with your output rules.
