I really require help or alternative about connecting a server from a Unity Web App in a restricted network
My situation
I work with Unity3D & SmartFoxServer2X and i export my Unity project to Unity Web Player application.
Our client has a restricted network.
In a NOT restricted network all the following solutions mentionned below works.
Attempt #1
First in the Unity app i use the normal standard socket of SFS2X in order to reach our server
Observation : Using the Unity Web App in this restricted network, there is no answer from the server so the connection seems to be impossible
Attempt #2
So i worked on the activation of the Bluebox solution in Unity3D in order to reach our server
Observation : Using the Unity Web App in this restricted network, it seems there is no answer from the server so the connection can't be established but the connection with bluebox freezes the Unity web app for a while (some seconds)
Attempt #3
So i made in unity a button to ping the server, but this failed to ping the server in the restricted network
Attempt #4
Then i made an html5/javascript connexion with SFS2X API. The idea was to allow unity web app to communicate with the server via an html5/javascript app in order to not be filtered.
Observation : Combining the Unity Web App (for 3D and GUI) and the Html5/ javascript app (for connexion) in this restricted network, a response from the server is received but the connection always failed with the error : is the server running at all ?
Attempt #5
Last try, I installed the flash example BattleFarm in our server. This flash example uses bluebox and normal socket. The client with a restricted network can connect after seconds and play with.
Conclusion
So i can conclude the following points :
- SFS2X is not the problem
- Our server seems to be well configured
- Perharps i improperly used the SFS2X API in Unity ?
- Perharps Unity apps are not authorized to connect out from the restricted network ?
- Perharps Flash apps are not filtered because frequently used in the web ?
Questions
Is someone have the same difficulties ?
Where are the wrong parts ?
Is someone have an example of unity web app using Smartfoxserver2X in Bluebox mode ?

In a non restricted network it's ok, it's works. 
So if i want SFS2X listening the 80 port, must i change the listening port of Apache and set the listening port of SFS2X to 80 ?
