Django server in one computer, client in other computer Problem

[guochengli]

I downloaded the latest django-dajaxice zip file from github then unzip it. Then I enter django-dajaxice-master/examples folder, run 'python manage.py runserver 13.122.241.172:80', (which is my computer's ip). The server started normally. In this server computer, I can visit http://13.122.241.172/ and the page displays normally. Then I click the 'Hello' button, I can get the right response. In my collegue's computer, whose ip is 13.122.242.16, he can visit http://13.122.241.172/ , BUT, when he click the 'Hello' button, there is NO response!
Then I check the command window, I see when he click the button, my server never receive the "GET /dajaxice/simple.hello/?argv=undefined HTTP/1.1" request! I am so confused by this problem and have been working on it for three days. Anyone could help me? Thanks so much.
The version of django is 1.4.20.

•Thanks for your help to this topic. I'm newbie here. Stackoverflow really a great place.
•Now I have found the problem's crux: In my server computer I use IE11, BUT in my colleague's computer, he uses IE9. If he changes to Chrome, it will be OK. But it still confuses me how should I do with other people who only have IE9.
