You may be able to get this working using a reverse proxy, though I expect not all links will be properly updated to use the new URL since they are built based on the Base URL and not the request url.
I think that we've tried a few different reverse proxy situations and found that some of the icons, images, and fonts do not get served up correctly. Aside from that, it seems to work okay for navigating the content. Do you have a way for us maybe to address these icon and font issues?
It would likely be a misconfiguration of the proxy or of JIRA's understanding that it is behind a proxy which would cause this.
