I am trying to get our on-premise Jira connected to Freshservice.  The instruction guide HERE says that you should use ngrok to publish your jira externally.  There are some security implications of doing this though and we need to be able to only allow traffic into our firewalls from the Freshservice addresses.

Support have told me that it is not possible to limit the traffic.  However I did find this article HERE that detailed IP addresses to restrict but the guide guide is for Freshdesk and not Freshservice.

Does anyone either know what IP addresses Freshservice requests come from (Europe region) or can help me isolate the Jira traffic so that only web requests from Freshservice are allowed to communicate with our internal Jira instance.

Thanks in advance.
