The Gate of No Boundary has two modes: fixed point connection and vast domain connection, which are quite similar to teleportation arrays, which also have public teleportation arrays and private teleportation arrays.
The so-called public teleportation array has publicly available coordinates, which any teleportation array can connect to and then initiate teleportation.
In contrast, the coordinates of a private teleportation array are not disclosed, and only by knowing the coordinates can one connect to it.
To prevent coordinate leaks, private teleportation arrays are also built on movable platforms, and after use, they are moved to another location.
Or, physical objects are suspended on the teleportation array, and if forced teleportation occurs, it will directly hit the object, possibly causing serious injury or merging with it.
The defensive measures for private teleportation arrays vary, whereas the defense for public teleportation arrays is very standardized—heavily guarded.
