Updated Hosted Email Security IP Addresses

First Published:01/27/2021 Last Updated:03/08/2021

SonicWall will be updating IP addresses for the Hosted Email Security (HES) platform in North America.

NOTE:  HES for Europe does not need to update IPs.

Network administrators will need to update access rules to allow for the following HES subnets:

  • 173.240.210.0/24
  • 173.240.213.0/24
  • 173.240.214.0/24
  • 204.212.170.0/24

The subnets can also be found in the HES FAQ KB article and firewall settings.

NOTE:  When updating the firewall make sure to disable and enable both NAT and Access rules so it will take affect.
