My Network: Cable Modem (Motorola Surfboard) connects to AirPort Extreme 3rd Generation which connects to AirPort Time Capsule (Time Capsule is set up to extend network) Port 443 is closed. Problem is that I need it open for more than one device. All my Macs, my iPhones and iPad need to be able to sync contacts which uses port 443. How can I open this for all devices on the network? I know how to open it for one device but that isn't going to help.
