The best way to go around this is to whitelist the main domain/URLs used by payment providers you use. > > Alternatively, you can allow all connections via the POS on a monitored network and see the URLs that are being utilised by the POS PRO app and Apple then allow these on the firewall. Before installing SumUp POS please ensure the following rules are created: **Open ports: 21,80,443** this will ensure your payment integrations will function and you can access the app store for installation and updates. Also please whitelist the following domains [thegoodtill.com](http://thegoodtill.com/) [itunes.apple.com](http://itunes.apple.com/) [x.itunes.apple.com](http://x.itunes.apple.com/) [albert.apple.com](http://albert.apple.com/) [gs.apple.com](http://gs.apple.com/) For SumUp Payments please whitelist the following: [solo-edge.sumup.com](http://solo-edge.sumup.com/) The IP addresses used are **104.18.17.137** and **104.18.16.137**. A TCP protocol is used and the **SSL (TLS) port is 443**.  Once you have done this your device will be able to communicate correctly with our servers and function as normal.![](https://support.thegoodtill.com/hs-fs/hubfs/Knowledge%20Base%20Import/thegoodtill.freshdesk.comsupportsolutionsarticles9000190338-network-securityhit-1.gif?width=1&height=1&name=thegoodtill.freshdesk.comsupportsolutionsarticles9000190338-network-securityhit-1.gif) -
