Feature flag management
To ensure optimal functioning of features which are under feature flags, you need to enable traffic to the URL
features.netscalergateway.net.
Feature flags are used to enable or disable features dynamically. If an issue occurs with Mobile Productivity Apps in production, the affected feature can be disabled dynamically, even after the feature is shipped. To do so, we use feature flags managed by Citrix.
No manual configuration is needed to enable traffic for feature management, except when you have a firewall or proxy that is blocking outbound traffic. In that case, you need to enable traffic using specific URLs or IP addresses, depending on your policy requirements.
IP addresses
If you must list IP addresses in an allow list, include the following IP address to allow traffic to
features.netscalergateway.net:
-
57.153.121.183 (for Europe West region)
-
172.202.161.151 (for US South Central region)
-
48.218.128.128 (for Japan East region)
You can add these IP addresses to ensure that your firewall configurations are updated automatically in keeping with the infrastructure updates.
System requirements
If using NetScaler Gateway with split tunneling set to OFF, ensure that NetScaler can resolve and connect to
features.netscalergateway.net over port 443.
