Limitations of using Internet Explorer 7 and 8

For the best performance, you should use the latest version of Firefox, Google Chrome, Safari, or Internet Explorer. You can use Internet Explorer 7 and 8, but they have the following limitations:

  • You cannot drag and drop files onto the map.
  • When importing data from a file, only the first 750 rows of features are displayed (compared with 1,000 rows for fully supported browsers).
  • When opening maps with lots of features, you may see a long-running script error message.
  • When leaving the map viewer window without saving, you may lose your work.

Firewall settings

Portal for ArcGIS communicates on ports 7080, 7443, 7005, 7099, 7199, and 7654. You'll need to open these ports on your firewall before installing the software. For more information, see Ports used by Portal for ArcGIS.

External access

If you'll be using Esri-provided services, such as basemaps and data from ArcGIS Online, the machine hosting Portal for ArcGIS will need access to the Internet. If your portal will not have access to the Internet, you'll need to perform some additional configuration steps to ensure your portal is pointing to local resources. For instructions, see Configuring a disconnected deployment.

Portal for ArcGIS authorization

Portal for ArcGIS requires authorization. For more information, see Authorizing Portal for ArcGIS.
