Re: VPN for Multiplayer Games Up and running
@Chris to answer your questions:
1. Yes, all must join. I don't own 25.0.0.0/8 (but wish I did!). That belongs to the Ministry of Defence in the UK, but it is not publicly routed, so we are rather naughtily squatting on it. It's what Hamachi does, too.
2. You can use whatever discovery protocol you want, since you are essentially connected to a giant, Internet-spanning Ethernet network. The network's your oyster. You could use UPnP, SLP, Bonjour, WSDiscovery, NetBIOS ... anything that works over Ethernet will work here.
I suppose that, if it were really helpful, I could set up a script to pull the DHCP server's lease table and dump it over the web. But that would not tell you anything but the number of devices, and the (virtual) MAC address and the IP address associated with it. It might also risk the privacy of those would rather keep quiet on the network. Still, if people think that might be good for something, I could set that up, but it wo n't help you find gamers or anything.
If Windows says you have no Internet access, it must be true. In fact, it is: I have explicitly not enabled routing to the Internet, and there is no default gateway nor DNS service. It seems overkill to me to set that up, especially when you can use other means of doing discovery that work, and most gamers seem to use IP addresses anyway. But maybe I'll reconsider if there's a case for it. Of course, offering public Internet access would be out of the question.
Having said that, somebody has connected. Could that be you? Check your adaptor to make sure it has an IP address assigned. Or if you don't mind, tell us what your computer name is, as specified in the conf file, or as assigned to your computer by Windows.
Try pinging 25.0.0.1. If you do not see replies, there's a problem. What is the last thing you definitely remember working?
You can tell if --generate-keys worked. You'll see two prompts, asking you where to store both your private and public key files. If you have a *.priv file in your tinc directory and a file in your hosts directory that matches your computer name, as given in the conf file, then this stage completed successfully and you need to install the service using "tincd --bypass-security" as instructed.
Let me know how you get on.
