Red5 problem

Hi

I installed RED5 plugin sucefully but local system(Openifre 3.6a ,Spark2.5.8) works fine … when i connect some other system same lan not working it shows internet is not connected and one more thing i am unable to call computer to computer also when trying to call it shows Session Closed due to Closed Remotely.

Note: I opened all port and firewall also…

& I attached the screenshot also…
