StreamSocketListener doesn’t listens on all adapters of Windows Phone 8.1 Simulator

Question

I have StreamSocketListener.BindServiceNameAsync( "11111" ) call in my WP 8.1 WinRT app, and another StreamSocketListener.BindServiceNameAsync( "22222" ) in my CodedUI test running on the same simulator.

The behavior of those 2 calls differs dramatically, here’s the nmap port scan of my emulator’s IP addresses:

Nmap scan report for 169.254.26.186 (="Windows Phone Emulator Internal Switch")
22222/tcp open     unknown
11111/tcp filtered unknown

Nmap scan report for 169.254.80.80
22222/tcp filtered unknown
11111/tcp open     unknown

Nmap scan report for Mah-PC (192.168.1.175)
22222/tcp filtered unknown
11111/tcp open     unknown

Nmap scan report for 192.168.33.1
22222/tcp filtered unknown
11111/tcp open     unknown

The “filtered” ports are really closed, i.e. my client fails to connect to those ports.

The documentation for BindServiceNameAsync variant I’m using says “method binds to the local IP addresses of all network interfaces on the local computer”. Is there a way to make it work as advertised?

Thanks in advance.
