nft-simple-fw

nftables framework ruleset comparting traffic into different zones.
Supports private subnets and vpn interfaces and provides a custom template for nft-blackhole.

Uses performant interface group matching for distinguishing interfaces.

default zone policies

filter type

  • public, private, forward: reject
  • vpn, output: accept

Usage

  • Customize conf.def and the filter zones in zones to your liking if you don't agree with the sane defaults.
  • Assign interface groups via systemd-networkd (see conf.def), create/edit services.d/{forward,private,public,vpn}/*.nft files for the services you wish to use and load via nft -f fw.nft, or use the supplied systemd service file systemd/nft-fw.service, which expects the files to reside in /etc/nftables.
  • If you are using nft-blackhole, symlink nft-blackhole/template.nft to /usr/share/nft-blackhole/nft-blackhole.template.
