Adding a quick update.
I believe I have everything setup correctly, issue is that I cannot see my own server, hosted either on my pc or another pc on my local network. All the noob stuff has been checked, firewall blah blah stuff of course. Here's where it gets weird tho, while ports are forwarded, it will show up as an Internet server, cannot connect tho get reject error, but will not show up on LAN.
Again, any help here would be greatly appreciated.
