I'm not sure who owns the NAT module as such, but could anyone take a look at https://github.com/NixOS/nixpkgs/pull/84949 and merge it if it seems reasonable. It's a small change and I've had to do it in my config locally to fix the issue

#84949 (by bqv, 6 days ago, open): nixos/nat: substitute iptables for compat under nftables
<bqv>
there's probably a nicer solution but until one is presented, this will at least allow people to use networking.nat when nftables is on and firewall is off
