In order to ensure accurate security and access as you are setting up your accounts with your bank, you will want to define the specific IP addresses that are trustworthy and acceptable. This is known as whitelisting.
You will want to make sure to provide your bank with a list of these addresses to be enabled:
For Production Accounts:
188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168
For Testing Accounts:
22.214.171.124, 126.96.36.199, 188.8.131.52, 184.108.40.206
To make sure that you cover all bases, we advise providing both the testing and production lists to the bank.
