Updated Hosted Email Security IP Addresses
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:
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.
