Using the Apache proxy to implement NAT technology solutions

Using the Apache proxy to implement NAT technology
I configured the IIS Web site and the Apache Web site in the form of a dual LAN IP on the server, respectively.
such as IIS using IP is 192.168.3.114:80,apache using IP is 192.168.3.115:80
Then I want to use Apache reverse proxy to enable users to access the 8080 port of the extranet IP when the switch to 192.168.3.115:80
How does a virtual host write?
Here are some of my own code to write, how to change? Ask the great God for advice!

Namevirtualhost *


ServerName www.h.com
proxypass/http://192.168.3.115/
proxypassreverse/http://192.168.3.115/

------Solution--------------------
1. If IIS and Apzche are two different servers, and one of them is exposed to the outside network, it can be another matter. 、
2. If IIS and Apche in the same intranet, the same server, just the server has more than one network card, this can be the way I said above to solve
So. You must describe the environment first.

------Solution--------------------
Please take a careful look at
Let Apache reverse proxy IIS and multi-domain settings
Apache Agent IIS 80-port implementation coexistence
