How does collaboration actually communicate from Portal to AGOL?

GWaltersOZ

Hi,

we have set up Portal to ArcGIS Online collaboration so we understand that it communicates between the two however, we do not understand how it does it.

Our internal server is behind a firewall. The services themselves cannot be reached publicly, so could someone describe the ports etc. that are actually used to send the sync packets please?

This is vital for us to present to our security team. Otherwise it is being viewed as some dark magic and can't be trusted.

Thanks,

Gareth

When collaborating between ArcGIS Enterprise and ArcGIS Online, what changes are required to my network's firewall?

In this configuration, all communication is initiated by the ArcGIS Enterprise portal. As such, network firewall rules must support outbound communication over port 443.
