So I have been trying to get a server started and it's has been nothing but a pain. I started a Direwolf20 1.5 on one of my spare computers in my house on the same network and played it on my main computer and my friend on another network could connect to that computer. But the server was laggy because it didn't have the greatest specs. So I moved onto my gaming computer running an FX 6300, 8gb DDR3, Radeon hd 7870 (Tahiti LE), windows 8. and now I can't get him to connect to me what-so-ever. We have both did port-forwarding but it worked before which is confusing me. I have tried using a VPN service like Tunngle and it didn't make a difference. I can connect but he can't connect to me, it keeps telling him can't reach server. I have tried everything I could think of and I don't know how to get it to work.
