Suricata 6.0.9 on Ubuntu 22.04 not getting traffic at all

Hi,

Im not an expert on suricata nor linux, but do you think that there could be something wrong with my configuration or the way operation system is configured?

Shouldnt something be in the 163 IPv4 packets, something that could trigger an alert with ET/free or at least something on the eve.json that is not UDP traffic?

What could be the next steps to try to identify the problem?

Thanks!
