Firewall Exceptions

Required Internet-Bound URL Rules

Certain outbound URLs require firewall exception rules to allow Mersive devices and applications to communicate with relevant services. Not all firewalls leverage URL-targeted rules, and specific IP addresses to open are available through the links.

It is not recommended to restrict access by IP address, as IP addresses can change without notice.
