от фрееско.орг: "FREESCO (stands for FREE ciSCO) is a free replacement for commercial routers supporting up to 3 ethernet/arcnet/token_ring/arlan network cards and up to 2 modems.
Why should you use Freesco?
Ease of use - it's insanely easy to set up
Thoroughly documented - it's more or less self contained, read one doc and you're off and running
Like most players in this field, it runs off one floppy
FreeSco runs in as little as 6 Mb RAM.
