Outbound access

Licensing

Posit recommends license file activation, which requires no outbound network access. A license file describes the license offline, so it removes the outbound requirement below.

Required for license key activation only:

If you activate with a license key, all Posit professional products require outbound access to wyDay TurboActivate/TurboFloat for online license activation:

Address | https://www.wyday.com
Port | 443

Your networking team might need to add the port number from which the activation key downloads to a safe sites list.

Email (SMTP):

Connect sends emails for scheduled reports, notifications, and content sharing. See Email configuration for SMTP ports and setup.

Network interface cards

You do not need to provision a dedicated network interface card (NIC) for Workbench, Connect, or Package Manager. A standard 1 Gbps NIC is usually sufficient unless your applications ingest large amounts of data that fully utilize its capacity. But in most cases, this is not necessary.
