Thank you again!!! Just like you say, my iphone is connecting to the same Wi-Fi Network as my computer. And my Firewall will also be disable. so i think that can absolute port 8887 get through, am i right? but when i open with http://IP-adress:8887/examples, that show me nothing.(it is connected, but there are nothing in there.) I have also tried through hostname.local:8887/examples to open it, but that doesn’t work either. If i use Phonegap (port:3000) that html can open on my phone . I guess that mean, my mac has maybe no problem. Have a idea, where is the Problem, or i do something wrong?

Thank you very much!
