Connect to Gitlab behind Sophos firewall

[Bart Stavenuiter]

We have our own gitlab ce running on a on premise server within our office. 
I would like to connect Jira to Gitlab so we can track issues and mention issues within Gitlab. However, we seem to be unable to connect because of the Sophos firewall. 

What do i need to do to allow jira to fetch data from gitlab? Whitelisting domain? ip's? or opening specific ports?

This page isn't exactly clear on this
https://confluence.atlassian.com/cloud/atlassian-cloud-ip-ranges-and-domains-744721662.html

any idea's?

Hey Bart,

That page can be a bit much to digest as it's intended to be a comprehensive listing of inbound and outbound access you might need to add.

Since the Jira application itself (and not a CDN) will be attempting to access your GitLab CE, the range of IPs you'll need to whitelist is limited to the "Atlassian Cloud" section of that document. For short, you can grab the current list at https://ip-ranges.atlassian.com.

If you're also looking to do port restrictions, Jira Cloud would at most be attempting to use the GitHub Enterprise listed ports of 443, 80, 22, and 9418. I would expect things to work even with just 443 open.

Cheers,
Daniel
