How to set up networking in Jira?

Question

JIRA

Good afternoon!
I installed Jira on the server (trial), got acquainted with the possibilities, liked the system, but the question arose:
- how to make it so that users can connect through the user portal and form their request, while the server is not connected to the Internet? those. how to set up network interaction between the user portal and the server where Jira is located.
And one more question, but this is more likely to expand knowledge:
On the net, on the forums dedicated to Jire, there was a question about updating from the old version 4+ to the latest 7+, but there was no clear answer whether it is possible to update without losing data or not. .
Will it be difficult to update if the difference in versions is so big and is it possible to do it without the help of Atlassian specialists?
