Are you sure that the server machine is the local IP that you've listed (btw, you dont need to mask the end of your IP, it is local, it doesn't matter, you only need to mask your global ip on images)
Type ipconfig in commandline on your server machine to double check it is the correct local IP.
If your router has DMZ, appoint it to your server local ip, this is a good test to make sure it isnt anything external. IF DMZ works, then the issue lies elsewhere. Don't use DMZ as a long term solution though.
