ankit2grover - I think we should leave this thread to duksunkim - I and a number of others have responded in your other thread. Next time, can you post a link to your new thread?
duksunkim. Just to confirm you problem.
You are issuing an http connection, using a standard URL with ";deviceside=true", and you get through to your Server when your firewall blocks NO ports. However when only Port 80 is open, you get a 500 error. Is that correct a correct summary of your problem?
To clarify, a standard URL is something http://www.google.com, can you confirm that you are not routing to a specific port using something like http://www.google.com:8080.
If my summary above is correct, then I suggest you start another Thread, with just that question.
However, I must admit that I think you only require port 80 to be open. Certainly my testing that is enough. I would try to confirm that your firewall is not doing some other blocking. In addition, you ask which ports to open. I would suggest your firewall logs might provide that answer.
Also I would try getting an http page from some other site, just to prove that the problem occurs with all sites, not just yours.
