The iptables extension has been obsoleted and removed a while ago and 
management of the forwarding rules is now done by the service itself 
through the nftables API. See the related `--nftables-*` command line 
options.

Probably the kernel's nftables module isn't loaded or something. See if 
loading `nf_tables` makes a difference. Perhaps there are some 
distro-specific packages you need to install to get nftables support going.
