Firewall and filter are two things totally separated!

- If you want to do something like a "page filtering", like dansguard
   and squidguard, you can simple do it with python, because you have to
   act like a proxy that leave of not visit a page.
- If you have to do a firewall... I think you can't, especially if you
   are on win. Take a look at wipfw ( that do what you want

and for windows.

Why? All that work with networking (and not only that) work better with
*nix OS!

Firewall I don't think, and the same for the filtering (I know only
something like a plugin for squid, so for *nix platform).

win32COM for do what?

You can do it in not so difficult manner:
Take twisted and its proxy class, make some outline code (for filter the
pages) and enjoy! (work also on win)

P.s. Don't forgot to share your code, when it'll work :)
