iptables v1.8.3 (legacy): can't initialize iptables table `nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. about ghostnet

I'm having the same, any clue ?

From the Arch wiki

If you get this error: iptables-restore: unable to initialize table 'nat', you have to load the appropriate kernel modules:
modprobe ip_tables iptable_nat ip_conntrack iptable-filter ipt_state
