Some rules for my software firewall

[maniacut]

I'm using the normal free version of sygate personal firewall. I just set up a few rules that I think are good and if set up correctly will help me from having to decide whether to allow traffic when it has no chance of appearing on the internet. Can any network gurus confirm that allowing traffic (all protocols) in/out from 10.0.0.1 and 192.168.0.1-192.168.0.76 and 224.0.0.0-239.255.255.255 is a safe bet?
