When configuring Network Connector, it is important to be aware of a core component called Chisel, which is used to facilitate certain aspects of connectivity. However, this component may be misidentified by some firewall systems, such as Fortinet, which may classify it as “Backdoor.Chisel.” Despite this classification, Chisel is a legitimate and necessary part of Network Connector, especially when it comes to communication over the designated port 51445, being necessary a permission for it, so that the Network Connector can function normally.
