Since I have been using Norton DNS, it had been very slow to download from the apple app store. This includes podcasts, updates and apps. THis is affecting multiple devices. As soon as I change it back to the ISP default on the modem, the speed is fine again. All other web sites are ok. I have tried Policy 2 & 3, using both the primary and secondary as the primary DNS lookup, with the same results. I am reluctant to not to use Norton as I want the filtering. Any help or suggestions?
