如何仅限localhost上的程序连接这个anyproxy?

#### Which platform are you running AnyProxy

linux

#### The version of the AnyProxy

4.0.10

运行 anyproxy --port 5060 ，这样，在5060端口就建立了一个http
proxy server,不过这个port 5060 是外部ip可以访问的，如何仅限localhost上的程序连接这个anyproxy?

Start with the command-line entry point used by `anyproxy --port 5060` and inspect how the proxy listener address is selected on Linux. Verify the resulting listener accepts connections from localhost but rejects external access; the issue is done when that behavior is confirmed for AnyProxy 4.0.10.
