Our organization is leveraging the cloud instance of TestRail and we would like to integrate this with a private instance of JIRA. The JIRA instance is hosted and managed by a different group and is only accessible within the local intranet. Is this possible? From the integration instructions, it appears as though the cloud TestRail system must be able to log in directly to JIRA. Will the Atlassian TesRail plugin allow us to enable the same level of integration, or will there be gaps in the features available? The JIRA instance can access the internet, I believe.
