The assumption
My gaming firewall protects my connection.
The reality
Another player pulls your IP address from the game's peer-to-peer connection with free tools. With your IP they determine your ISP, your approximate location, and launch a DDoS that takes you offline during the tournament. In the worst cases the IP leads to a swatting incident. Your gaming firewall monitors incoming connections. It does not address the fact that your IP is already visible to every player in the lobby.
With Echoron
Transit moves your session across independent resolution points through the VX Encryption protocol. Your real IP is never exposed because your connection exists in a moving state that peer-to-peer queries cannot resolve.
