Problem with Firewall in 3G connection
Posted on 2008-10-17
I have developed two applications in C++, one is UDP client and other is UDP Server.
I tried to run both applications on the different computers connected to my home wireless router. I dont have any firewall / NAT in home. My application use WLAN interface and it works fine and give required result. I can see data is passing between two applications.
The problem is...
When I connect both client and server with 3G USB card (having disabling all other interfaces) modem, I dont get these applications connected. I heard that provider of 3G networks insert any firewall / NAT between two peers. I have to pass through the firewall.
Can you please help me how to communicate both cppliactions connected with 3g network.
Your response will be highly appriciated.
