Hello,

I’ve reached out to our IT to help us with the requirements. They’ve responded with the below and recommended I reach out to you for a response:

Your current Azure Network Security Group (NSG) configuration allows inbound traffic only on port 3389 (RDP). All outbound ports are set to default, which permits outbound internet access unless explicitly restricted.

To ensure uninterrupted access to Docusign services, please provide the specific outbound ports used by the domains listed below, so we can validate and, if necessary, explicitly allow them in the NSG rules:

• demo-b.docusign.net
• na1-b.docusign.net
• na2-b.docusign.net
• na3-b.docusign.net
• na4-b.docusign.net
• eu-b.docusign.net

Once the required ports are confirmed, we will review and update the allow-list settings as needed, in accordance with the Docusign Trust Center IP and domain guidelines, before the December 31, 2025 deadline.

Please advise on the specific ports required for outbound connectivity to the above domains.

Thank you,

Svetlana
