Effective March 25, 2016, IBM requests that you please allow 22.214.171.124/27, 126.96.36.199/27, 188.8.131.52/27, and 184.108.40.206/27 in addition to the ranges you currently allow.
This is particularly important for our SmartCloud Notes clients to allow traffic on port 1352 as well as 25 (for SMTP relay) to this new range to avoid mail routing or other issues.
IBM recommended to check this page with all detail related. If you have any questions about this range please ask to [email protected]
