Hi. I'm having difficulty getting firewalls to work to prevent certain devices accessing the internet.

I've applied fixed IP addresses to the devices then setup rules to prevent Outbound (& inbound) traffic but they simply do not work.

Searching for the issue suggested there was a problem with sky routers simply not working as far as firewall were concerned but that was some time ago. Is this still a known issue?

Thanks.
