If I configure a reverse proxy on Apache for my server app, will it need to be able to see my external IP address? And yeah, I'm using Windows, so I have an NAT and a firewall. Is there a way I can let networked apps like ipconfig see my external IP
address, or is it really impossible? It'd be good if I could get it to work without having to turn off NAT.
There are still 4 failed targets and 5 skipped targets when trying to build Boost. There were some "__imp_" unresolved symbols when building Boost, before, too. I wonder if they're there because of zlib.dll. If so, how do I tell b2 where that DLL is?
I say this because when I built Node.js from source before, there were unresolved symbols for __imp_read, __imp_write and __imp_open, and specifying the path to the folder with zlib.dll in Visual Studio solved that problem.

I bound it to the wildcard address in the command line arguments when calling the .exe (I'm using Windows). And I already know the localhost address will work. I'm trying to see if the external IP address works. I just wrote a Dockerfile for this and
am building it now. Would the same thing happen with a Docker container?

I built the HTTP server example from Asio and tried to run it. Same problem. I set up port forwarding for port 8080, passed 0.0.0.0 as the address in command line arguments and tried to visit my external IP address in my browser (wrote an HTML page
to act as a landing page). Can't reach the app, as with my own server application. So either it's both of the possibilities mentioned before, or just that firewall needs to configured properly. Except it already seems like the firewall is allowing both
applications through. Maybe there's something in the configuration that I'm still missing, though.
If you are behind a NAT router then I don't think you can access a service port at the external IP address the NAT is actually doing translation for. To test within the LAN behind the NAT router simply use the local host address, either the loopback if you
are on the server host or via the server host LAN address. The port forwarding is only valid for incoming external traffic to the NAT router. This is one good reason why your server should bind to the wildcard address so that you can test it via any of it's
host's addresses.
