Updated Hosted Email Security IP Addresses
First Published:01/27/2021 
Last Updated:03/08/2021SonicWall 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.
- HES FAQ KB article: https://www.sonicwall.com/support/knowledge-base/sonicwall-hosted-email-security-faq/170504903060180/
- Firewall rules for HES: https://www.sonicwall.com/support/knowledge-base/firewall-settings-for-hosted-email-security-to-work-with-on-prem-solutions/171012195935960/
NOTE: When updating the firewall make sure to disable and enable both NAT and Access rules so it will take affect.
