TcpListener is not listening the specified port in a server with multiple NIC

Hi,

I am facing an issue in one of the client where the server is having two NIC - one for the internal LAN(192.168.0.XXX) and the other for the internet(192.168.2.XXX). I am having a client server application in C# where the client is communicating with the server application using port 50500 and the internal LAN IP.

But, when I check the port through "netstat -np TCP", the list showed that the port is listening to internet IP. If we check the client applicaion in the same machine, it is working. But when I disable the internet and check, the port is not at all showing in the list and the application is also not working.

Any help will be appreciated.
