Firewall Linux - A small and simple Linux based Firewall Distribution

It combines a smart Linux distribution (NixOS) with modern network services, a simple web interface and API to configure it. It's not meant to be a replacement to far superiour Appliances like pfSense or OPNSense but as an alternative solution for typical home use.

• PCEngines APU2/3/4
• Generic AliExpress Router PCs

Planned initial features

• Firewall (netfilter)
  • NAT
  • Rules
  • UPnP (miniupnp)
• DynDNS (ddclient)
• VPN
  • OpenVPN
  • Wireguard
• NTP (chrony)
• DHCP (Kea)
• DNS (Knot)
• TFTP (Netkit TFTP)
• Auto config backup

Design

Partitioning

The partitioning schema is kept simple and will be setup like this:

BIOS/MBR:

/dev/sda:
  /dev/sda1  swap  [SWAP]  # SWAP
  /dev/sda2  ext4  /       # FWLNX

UEFI/GPT:

/dev/sda:
  /dev/sda1  vfat  /boot   # ESP
  /dev/sda2  swap  [SWAP]  # SWAP
  /dev/sda3  ext4  /       # FWLNX

Operating system

As the base operating system NixOS is used.
