</a>. I want to add a rule to the IPCop box that will only allow<br>them to access a single public IP outside of our network.<br><br>--<br>This message has been scanned for viruses and<br>dangerous content by MailScanner, and is

I use URLfilter with my IPCop to block access to the kids computers at certain times of the day, I had been thinking of trying the whitelist thing for places like the library and such. Let me how you get it to work.
