I decided to set up a 'real' time exploiting environment. I tested with metasploit on my home network but now I'm trying to pen-test outside my network. I'm at my sisters house a few houses down. I opened up my network at home so my target computer at home can be open and seen on the internet. It's Windows 2003. I configured the routers at both home and at my sisters house. When running the simple win32 reverse, I get a 'connection timed out' error. I even connected the target computer directly to the cable modem and I still got the error. I'm not sure what's the problem.
For LPORT(sisters house), I have the router configured for port 4444 to be open. For LHOST, I tried both the router IP 192.168... and the actual IP and still got the connection error.
Not sure what the problem is. Any help/tips would greatly be appreciated it. I apologize if this has been asked before, couldn't find the solution. Thank you in advance.
