How to make redirection witout the port

[OmbreNoir]

I have set the port 8080.. but the problem, at my job I cant access to this port..

I try to make subdomain for redirection but he redirection at the port... so the result is the same...

it's possible to make a subdomain like jira.mydomaine.com  and this adress rest this adress?
without to set the JIRA port 80...

Thanks

Yes, you can configure a port or a load balancer to redirect port 80.

Example:

Proxy Adress = jira.com   (Port 80)    redirects trafic to=>   VMname:8080

(Just change the base url of your JIRA to the proxy address)
