Modern OSes use iptables implementation with nf_tables as a backend, e.g.:

$ iptables -V iptables v1.8.8 (nf_tables)

Pablo points out that we need CONFIG_NFT_COMPAT to make that work, otherwise we see a lot of:

Warning: Extension DNAT revision 0 not supported, missing kernel module?

with DNAT being just an example here, other modules we need include udp, TTL, length etc.
