Sorry for asking everything but I want to make sure there isn't any rejection.
I run the command you told me. To my weak understanding ther is no

root@xn--hadibakalm-5ub:~# iptables -L -nChain INPUT (policy ACCEPT)target

Chain FORWARD (policy ACCEPT)target prot opt source
destination
Chain OUTPUT (policy ACCEPT)target prot opt source
destination
