# Link/unlink the node from B3

The WIN node can be also linked or unlinked from Boomerang 3 as described in [B3 Domain Administrator Manual](https://app.gitbook.com/o/vTf4HrtXl9bgDwvJVSxV/s/PTZRr97g6y1opAswEdao/ "mention"). 

It is more convenient to do the linking from the gateway web interface but this method may be used if there is no access to the newtork where the gateway is installed.
