How can Android Emulator reach server on local network?

Issue

I want to connect to a server on my local network (10.134.0.178:80). The ip address of my machine is 10.134.3.12 and the ip address of the emulator Wi-Fi is 192.168.232.2.

Now I found out that you have to use 10.0.2.2 to connect to a server on your local machine. But the server isn't running on my local machine - instead it is a separate instace on my LAN.

My local machine can reach and ping the server without problems. The emulator not, but the emulator has internet access. So I can access e.g. www.google.com.

How can I connect the emulator with the server? The shown redirection rules only apply on port level. So how is this meant to be used? Other solutions only talk about a local server. Only one is talking about a similar case, but this is not working for me (no connection)

netsh interface portproxy add v4tov4 listenport=80 connectport=80 connectaddress=10.134.0.178

Additionally, I have to switch server instances (different ips/ports/addresses). So how can I use the Android Emulator in this case? To which address should the webservice calls be made? 10.0.2.2 or 10.134.0.178?

Solution

Don't know what the reason was, but the most plausible one is, that the server had a temporal issue. Now I can connect to my server without further changes!

One thing what still didn't work for me was ping, but it is listed under Local networking limitations:

Depending on the environment, the emulator might not be able to support other protocols (such as ICMP, used for "ping"). Currently, the emulator does not support IGMP or multicast.
