Earlier you posted a list of firewall rules like this:

 iptables -L -n --line-numbers reports

 Chain INPUT (policy ACCEPT)
  num  target                    prot opt source     destination
   1    ufw-before-logging-input  all  --  0.0.0.0/0  0.0.0.0/0
   2    ufw-before-input          all  --  0.0.0.0/0  0.0.0.0/0
   3    ufw-after-input           all  --  0.0.0.0/0  0.0.0.0/0
   4    ufw-after-logging-input   all  --  0.0.0.0/0  0.0.0.0/0
   5    ufw-reject-input          all  --  0.0.0.0/0  0.0.0.0/0
   6    ufw-track-input           all  --  0.0.0.0/0  0.0.0.0/0

So I would guess ufw.
