For IP filtering you will need to allow **34.89.173.157**, that is our production environment. #### **Access to the CMS** The CMS runs on https so it requires port **443** to be open. The following domains need to be whitelisted as well: **your-tenant.my.netpresenter.com your-tenant.my-api.netpresenter.com** **storage.googleapis.com** #### Slide Players The Players use port **443** (https) to connect to **your-tenant.my-api.netpresenter.com** and **assets.my.netpresenter.com** to check and download content. The Players also use websockets to get new content notifications and alert content. For this to work your clients need to be able to connect to port **6001**. An easy way to check if websockets are working is to check if the Live Logging button is visable in the Player details. ![Live Logging](https://www.netpresenter.com/wp-content/uploads/2025/01/image-15-1024x374.png) The Slide Player is also used for the Alert, Wallpaper and Lockscreen features. These also need port **443** and **6001** to connect to the server. #### **Desktop App** (DA) The DA also uses **your-tenant.my-api.netpresenter.com** (ports **443** and **6001**) and **assets.my.netpresenter.com** (port **443**) to fetch content and communicate with the server. The DA is used for Articles, Polls, Alerts and Ticker messages. The DA also uses push notifications, these use the following ports: **5228, 5229, 5230 and 443** to communicate with the Firebase servers. To get an up to date list of all the servers it’s best to check the firebase documentation: [https://firebase.google.com/docs/cloud-messaging/concept-options#messaging-ports-and-your-firewall](https://firebase.google.com/docs/cloud-messaging/concept-options#messaging-ports-and-your-firewall) At the moment of writing these are: **mtalk.google.com mtalk4.google.com mtalk-staging.google.com mtalk-dev.google.com alt1-mtalk.google.com alt2-mtalk.google.com alt3-mtalk.google.com alt4-mtalk.google.com alt5-mtalk.google.com alt6-mtalk.google.com alt7-mtalk.google.com alt8-mtalk.google.com android.apis.google.com device-provisioning.googleapis.com firebaseinstallations.googleapis.com** - [Content Creation](https://service.netpresenter.com/support/content-creation?hsLang=en) - [Settings](https://service.netpresenter.com/support/settings?hsLang=en) - [Configurations](https://service.netpresenter.com/support/configurations?hsLang=en) - [Requirements](https://service.netpresenter.com/support/requirements?hsLang=en) - [Deployment](https://service.netpresenter.com/support/deployment?hsLang=en) - [Security](https://service.netpresenter.com/support/security?hsLang=en) - [Cloud Services](https://service.netpresenter.com/support/cloud-services?hsLang=en) - [Guides](https://service.netpresenter.com/support/guides?hsLang=en) - [Product Sheets](https://service.netpresenter.com/support/product-sheets?hsLang=en) [![Netpresenter\_Logo\_2023\_500x75px](https://service.netpresenter.com/hs-fs/hubfs/Netpresenter_Logo_2023_500x75px.png?width=250&height=38&name=Netpresenter_Logo_2023_500x75px.png "Netpresenter_Logo_2023_500x75px")](https://www.netpresenter.com/) The visual employee and emergency communications platform © 2026 Netpresenter
