Transaction IP Velocity Filter

The Transaction IP Velocity Filter allows you to limit the number of transactions received from the same Internet Protocol (IP) address per hour. You can also use IP Address Blocking to block transactions from certain IP addresses in conjunction with this filter.

Multiple transactions that are part of the same order do not trigger this filter.

IMPORTANT: If you submit transactions using the Advanced Integration Method, you must submit the customer IP address (x_customer_ip) with each transaction in order to use this filter. For more information, talk your Web developer or the person who performed your integration.

The filter status, Filter Enabled, Filter Disabled or Not Configured appears at the top of the page.

To enable the Transaction IP Velocity Filter:

Step 1: Click the Enable Filter check box at the top of the page. Or, to disable the Transaction IP Velocity Filter, make sure that the Enable Filter check box is deselected.

Note: If you choose to disable this filter, the IP addresses previously entered will still be saved.

Step 2: Enter the maximum number of transactions to be allowed from the same IP address per hour in the Transaction IP Velocity Threshold text field.

Step 3: To add an IP address to the IP Address Exclusion list, enter the first set of digits (up to three) of the IP address in the first text field, the next set of digits in the second text field and so on and click Add››. You can have up to 500 IP addresses in your IP Address Exclusion list. IP addresses included in the IP Address Exclusion list can submit an unlimited number of transactions per hour.

Step 4: To remove an IP address from the list, click on the IP address you would like to remove in the list on the right side of the page and click ‹‹Remove.

The Total IP Address Count indicates the number of IP addresses currently included in the IP Address Exclusion list.

Note: The Transaction IP Velocity Filter does not filter America Online, Inc. (AOL®) IP addresses. This is because transactions submitted from a computer using the AOL Web browser are assigned a dynamic IP address from one of several AOL IP address ranges. Since it is possible that you will receive transactions from the same AOL IP addresses, these IP address ranges have been excluded from the Transaction IP Velocity Filter. For more information about AOL IP addresses, please see http://webmaster.info.aol.com/proxyinfo.html.

Step 5: Click the radio button next to the appropriate Filter Action for this filter.

Note: In the event that a transaction triggers more than one filter, and each filter is configured with a different action, the most severe filter action will be applied to the transaction. For example, you might configure filter A to decline all triggered transactions, and filter B to authorize but hold all triggered transactions. If a transaction triggers both filters A and B, it will be declined rather than authorized and held for review.

Step 6: Click Save to save your settings or click Cancel to cancel the action.

 

Your saved settings are applied immediately to all transactions screened by the Advanced Fraud Detection Suite.
