Get Mandrake Multi Network Firewall now - hard to find it...
Here's the link to download Mandrake MNF.
I became frustrated trying to find this link .They buried it under all their paid links -.-
Actually, I don't even know if this is the Single Network Firewall or if it only works with Mandrake v 10 +, or if it works with 8.1.
I don't think MNF comes with the 10.1 cds so if u don't have it yet, download it cos i hear its a great alternative to Smoothwall and iPCOP.
