Which Internet Protocol (IP) addresses (subnets) compose the SAP Ariba solutions and SAP Business Network for firewall validation?
SAP Ariba strongly encourages you to validate postings from SAP Business Network using Hypertext Transport Protocol Secure (HTTPS) client certification of service.ariba.com, rather than hard-coding IP address access through firewalls.
Nonetheless, if an IP range is required, open the following range of IP addresses to support the full set of servers composing the SAP Business Network. This list applies for Applicability Statement 2 (AS2) inbound traffic (from SAP Ariba) to suppliers. The same IP range applies to SAP Ariba solutions, such as SAP Ariba Buying and Invoicing and SAP Ariba Sourcing.
