as it combines both ip and ip6 protocols in nftables.

systemctl enable nftables
 
Remove the Execstop in the nftable.service file. The file is usually located in 
 
/etc/systemd/system/sysinit.target.wants/nftables.service

Create a directory called nftables in /var/log and in it, create two files called
Input.log and Output.log to store the input and output logs, respectively. 
Now go to /etc/rsyslog.d and create a file called nftables.conf with the following contents:

:msg,regex, " Invalid-Input: " -/var/log/nftables/Input.log
:msg,regex, " Invalid-Output: "  -/var/log/nftables/Output.log
& stop

Save the file and exit. Now all the log for nftables will be saved in these files
