BullGuard Mobile Security suite includes a Firewall engine that will protect your device against unwanted intrusions or network traffic. This feature is designed for users who are usually connected to access points as it greatly reduces the risks created by working in public environments.
The Firewall module has 3 security levels to suit users’ needs. The security levels can also be adapted in turn by adding, removing or editing Firewall rules.
Security level: is responsible for the Firewall behaviour and how it directs both incoming and outgoing traffic. The levels can be further tuned by using Firewall Rules. Security levels:
Off: disables the Firewall filtering for all traffic.
Low: allows the traffic on all ports except for those blocked by individual rules.
High: blocks the traffic on all ports except for those allowed by individual rules.
Back: returns you to the BullGuard module screen.
Menu: allows you to access the Rules list and the Firewall Activity log.
You can specify the BullGuard Firewall what kind of traffic to allow or block based on strict rules through which you can block IP addresses or Ports. To add a new rule and to edit, delete or duplicate existing ones, click on the Menu button to manage your Firewall’s Rules List. Note that High and Low security profiles have their own rules and changes made in one list will not affect the other.
Add: starts the Guide that will takes you through all steps needed to create a Firewall rule.
Edit: allows you to edit the currently selected Firewall rule.
Delete: allows you to delete the currently selected rules.
Disable: allows you to disable the currently selected rule.
Make Copy: allows you to create a duplicate of the selected rule.
Restore defaults: restores the Firewall default rules. It will delete any user created rules as well.
Description: allows you to choose a name for the newly created rule.
Single IP Address: the rule applies only to the specified IP.
IP Address Range: the rule applies only to the IPs included in the defined IP range (192.168.0.* - the rule applies to all IPs starting with 192.168.0.1 to 192.168.0.255).
Next: takes you to the next screen of editing your Firewall rule.
Back: takes you to the previous screen.
The next step is to choose the ports the Firewall rules will be applied to.
All: the rule is applied indiscriminately to all active ports on the device.
Single: the rule is applies to the specified port number.
Range: the rule is applied to all ports included in the specified range.
Next: takes you to the next Guide screen.
Back: brings up the previous screen.
The last step in creating a custom-made Firewall rule is to choose the traffic direction the Firewall rule is applied to. The Firewall rules can apply to inbound or outbound traffic or both.
Click Finish to save the rule. If the Rule enabled settings is active, as soon as the rule is created, it will be applied immediately.
