hi every one
i am doing a penetration testing to a client and found a bug in jboss and i managed to upload jspspy web shell. but i want more than a shell i need to hack internal network.
i created meterpreter reverse_tcp and encode it 100% FUD and upload it and i started metasploit on my remote server and listen to port 1337 all things is okay . but when i run meterpreter on the hacked server i can get any connection . and also when i ping google i can get any reply always request timed out or cant find host name i think that there is a proxy or firewall itried every thing i know and many tools and trojans like darkcomet ultimate but failed . please i want a way or solution to that problem.

i will be very happy if any one helped me

thanks very one
