A firewall is a set of related programs that protects the resources of a private network from other networks. It
prevents hackers to access its own private data resource accidentally.
There are four firewall modes: “Disable”, “Low”, “Medium” and “High”. The table below shows what kind of
packets will be blocked in different modes.
Note: “Firewall” function is only available in “Router” mode.
