Network filtering software and questions?

[lolcocks]

Okay, so I have a Linksys E1200 with DD-WRT big and apparently blocking websites does not work for https.


So I wanted to try any network filtering tools out there but I am completely unsatisfied with any of them.

I have seven devices connected wirelessly. None wired.
I can wire one if required.

I want to disable file uploading and email sites on 5 of these PCs.

How do I achieve this?

Won't using OpenDNS filter out all 5 PCs rather than just one?

Please help.

That's a very interesting question.

Most software firewalls will let you block traffic to and from any site you wish to add to a blacklist. That should take care of the email sites. If you want to block email servers, you can just block the ports for pop3, smtp and imap.

File uploading could be tricky, do you mean ftp-type uploads? You can block the ftp port (and the SSH port for sftp), but that would block both downloads and uploads via ftp (and anything that tunnels with SSH). Maybe look for browser add-ons or some more advanced Parental Control software?
Tough! I would love to hear some suggestions, as well
