Port Changes in New Release and Certification Environments - November 15

Effective Sunday, November 15, CME Group will standardize the client-facing port ranges for iLink Market Segment Gateways (MSGW) and Drop Copy for MSGW sessions across futures, options and EBS segments in the New Release and Certification testing environments.

The new ports are currently available in the New Release/Certification Request Center.

Ports for BrokerTec and BrokerTec Chicago sessions will not be affected at this time.
