What's the proxyName and portPort when deployed behind reverse proxy and NAT ?

[ycycn]

If jira behind reverse proxy and NAT

I want to access jira use http://1.1.1.1:111/jira

Internet <--->rouner[1.1.1.1:111]<--->reverse proxy[2.2.2.2:222]<--->jira(whatever)[3.3.3.3:333]

what's proxyName and proxyPort should be set in server.xml?

proxyName=1.1.1.1 proxyPort=111

or

proxyName=2.2.2.2 proxyPort=222

The server name and port should be set to whatever the proxy is announcing itself as on the internet, and hence the root of your base url as well.

If, for example, you want to see your Jira on https://yourdomain.com/jira then set the proxyname to yourdomain.com and the port to 443 (that's the default for ssl, so you don't need it in the address)
