Indeed, the Steamworks [api]ISteamMatchmaking[/api] and [api]ISteamMatchmakingServers[/api] APIs have this property, as do some of our own games, such as Team Fortress 2. In this case, you can use the Steamworks "Fake IP" system. A FakeIP is an IP that "looks" like a valid IPv4 address for most purposes, but comes from a reserved address space that is not used on the Internet. …

It is acceptable to apply a new certificate at any time, and so if you want to issue certificates more often, for example at the start of every match, that is OK. Every client must have a unique identity. If possible, use the platform-specific identities. (For Steam clients, this is a requirement.) …
