Terraform cloud worker execute remote-exec will be blocked by firewall

Hi, our team use remote-exec to provision remote machine. To make bastion machine more secure, We add a azurerm_network_security_rule to limit source IP address. But we don’t know the IP address of Terraform Cloud worker. When it executes remote-exec , will be blocked by firewall. Is there any way can get worker’s IP address list? Thanks!

Terraform Version

Terraform v0.12.18

Hi!

Although we publish an IP Ranges API, as noted in the documentation those ranges do not allow for execution of Terraform runs against local [non-public] resources.

Running a Terraform Cloud Agent, however, would allow you to provision with the desired limited access you’re looking for, which is included as part of our Business tier.

Thanks!
