I am taking this back to the list, as it is handy for lost of people.
Large sites like those are NOT one computer. Facebook actually has
184.108.40.206/20 for possible servers, and they may move. To filter stuff
like that, you need a real web filter. I have used Untangle in a few
clients and it works well. However, using it with m0n0wall can be a
challenge depending on the functions you need. For example, Captive
Portal will not work "through" Untangle is it is a b-router and rewrites
the MAC address.
Or, you can ping each server, the do a 'whois' on the address block, and
block the whole thing, and hope it is not hosted somewhere (like
GoDaddy) with websites you need for business reasons.
