For certain Asperato integrations it is necessary to whitelist the following IP addresses
- Test server 126.96.36.199 and 188.8.131.52
- Live server 184.108.40.206 and 220.127.116.11
These IP addresses are required when Salesforce connection is established with Asperato server via user credentials and eliminates the need for verification codes / security tokens.
Customers are generally advised on case by case basis, when IP ranges need to be updated with either of the above addresses. Please check with Asperato Support before whitelisting IPs, as your integration may not require this step.
