    <p>I'm trying to add networking over the internet to my game, using Peer to Peer. I have already implemented a LAN only version, which uses .NET's peer to peer classes to connect within the local network.</p> <p>I realized I need to use UDP hole punching in order to establish a connection to other clients that are behind a firewall.</p> <p>This is how I have started to implement it: The server is a HTTP server using very simple PHP scripts to get the job done.</p> <ol> <li><ul> <li>register name on server, sending the private ip address and port as a GET variable</li> <li>when the server gets a registration request, it will save the public endpoint and the private endpoint</li> </ul></li> <li><ul> <li>request to connect to another client.</li> <li>the server will return the private and public endpoints of the client</li> <li>every two seconds, the second client will check in with the server, and if there is another client attempting to connect with it, it will get its endpoints too</li> </ul></li> <li><ul> <li>both clients start spamming each others public endpoints until they get a valid response</li> </ul></li> </ol> <p>Now I have a bunch of questions </p> <ol> <li>Can the server be a HTTP server?</li> <li>When I make a request to an HTTP server, the client port changes each time a request is made. Is a private endpoint always matched to the same public endpoint?</li> <li>Does the request to the server have to have the same source endpoint as the UDP messages to the client?</li> <li>Is there a way to connect to an HTTP server in C# using a specified source endpoint?</li> <li>Are there any problems with my implementation?</li> </ol> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
