According to the documentation (https://wiki.debian.org/nftables) there are no filter rules by default, so the assumption is that there is no filtration of packets by the software at the kernel stage. The configuration file '/etc/nftables.conf': #!/usr/sbin/nft -f flush ruleset table inet filter { chain input { type filter hook input priority 0; } chain forward { type filter hook forward priority 0; } chain output { type filter hook output priority 0; } } Is it correct to interpret this configuration file that filtration is _not_ active?
