I need to test Confluence for my company and for that I need to integrate it with our Jira Software. The problem is that we have Oath Authentication, so in order to integrate Confluence and Jira I need to add ip adresses range to the white list. My question is how can I limit number of IP adresses that i have to add to white list to minimum. I found IP adresses ranges on the atlassian support sites but theres too many and i want to limit it to only a few if possible.
