Provide IPs to allow connection between GitLab.com and self-hosted JIRA instance
If customers want to link GitLab.com with a self-hosted JIRA Server, they need to whitelist a certain IP or an IP-range to be able to let GitLab.com talk to the JIRA instance.
The current answer to this issue is that since GitLab.com is run in the cloud, IP addresses can change at any time without warning and it's not possible to integrate a self-hosted JIRA server. Slack conversation for reference: https://gitlab.slack.com/archives/C101F3796/p1510310205000017
If this is not possible, this limitation should be added to the FAQ-page for GitLab.com.
