I tried to just parse “$ sudo iptables -L” output from the host but that is ridiculously long.

So I install GUFW instead as it summarizes the Host Firewall tremendously:

My Host’s Firewall Report

Only in the Report do you see multiple entries for:

  • TCP port 53 and UDP port 5353
  • UDP port 53 and UDP port 5353

But those entries are used by DNSMASQ, AVAHI and KVM/Virt (182.168.122.1)
