"fdgw" is tool kit to make one floppy version NetBSD from NetBSD source itself.  I've tested fdgw compilation on NetBS 1.5 stable sources. I believe you can compile fdgw on all NetBSD 1.5 stable version ( netbsd-1-5 branch ).
Fundamental usage of fdgw is router( IP forwarding equipment ). See "natbox" model, which is a basic router. This model supports both IPv4/IPv6, NAT and DHCP by default. For example, you can use this as a pseudo firewall for your home.
There is ADSL router model (image file is "adslrouter.img"). This model supports NAT, DHCP, and PPPoE (pppd and rp-pppoe) for ADSL.
Fdgw supports many network interfaces in ISA, PCI, PCMCIA and CARDBUS bus as could as possible on NetBSD. See "network interfaces" section for more details.
ftp.fml.org provides floppy images.
