// DNATs it to InternalPort, where the in-process VNC server actually
// listens. Both flow over the WireGuard interface. AgentLegacyPort is
// the TCP port the per-session agent used before it switched to Unix
// sockets; kept here so packet captures from older builds still get
// tagged, and so any future on-wire agent variant has a reserved port.
