Just moved to Vodafone with Ultra Hub and very happy with the service so far. The only issue I have is with parental controls using SecureNet. The service appears to work using DNS filtering but this is very easily bypassed by any child who can simply change their DNS servers on their device from the ultra hub (which is assigned by dhcp) to - say - Google on 8.8.8.8 and this then bypasses all the controls, rendering the service useless.
This can be fixed by adding a simple firewall rule to permit only dns traffic only to 192.168.1.1 (the hub) and block everything else. However, on the firewall page there is no options other than a toggle button to turn the firewall off (and who would do that !!!). Is there a way to add such a rule please?
