Firewall and DMZ
Firewall and DMZ apply only when the OBi is set to work in the router mode. The firewall filters incoming packets from the
WAN side only. It provides protection against some threats from the WAN side. There is a global firewall enable option
which, when disabled, disables all the firewall components. In addition, the three firewall related features, NATRedirection,
DRDOSAttackProtection, and VPNPassThrough, will take effect only If firewall is enabled. Below is a screen shot of the
Firewall and DMZ device web page.
