That doesn't matter for me. I'm connecting via localhost at any time, my friends via my dyndns IP at any time. It may help in your case but it's not the general case. The OPs case was that he couldn't connect to his own server. I assume he got problems with his network adapter prioritys. At least we could reproduce the issue with Windows 8 and Hamachi/Tunngle.

Are you using Windows 8, too? My friend can magically connect now. It seems a PC reboot did help and now we're testing what could cause this behaviour. Tunngle/Hamachi network priority settings is one thing. I'll report back. UPDATE: Server output whit comments: TL.DR: After all this my friend did a PC reboot and all worked again. He can connect now, in fact he's connected right now ipconfig /renew or /flushdns didn't help. Also deactivating and activating the network adapters didn't help. DO NOT USE TUNNGLE WHEN USING WINDOWS8 I hope this will help anyone. Update2: Oops forgot to mention that I'm using a dynamic dns service to get a static public IP address. Using tunngle only does not work for us.

His server is running well. I can connect to his server but he can't. With the last build everything was fine with his connection. Little Update: He switched to his Mac and now he can join. For me it seems to be a win8 / RakNet problem...

We (a friend of me and myself) got the same problem... nearly. He can't connect any server but I can. We tested it with the public Server: Keifleaf.no-ip.biz which worked for me but not for him. We also tested it while I was hosting a server and he was hosting one. Everytime I could connect but he couldn't. We both did a fresh install of everything. The only real difference between our PCs is he uses win8 I use win7. My idea was that maybe RakNet is not working well with win8 maybe? What OS are you using Snake?
