Business Edition/ESET Smart Security/Personal Firewall
ESET Smart Security Firewall behavior and User Interaction
The Personal firewall is a device that acts as a network traffic driver, controlling communication within the local network or internet. Using predefined rules, the firewall analyzes this communication and decides for or against its establishing. The firewall's most basic function is to protect private networks or computers against intrusion from potentially dangerous outside networks or computers.
There are 3 separate firewall modes to choose from, according to the desired level of restriction. To change the behavior of your firewall, choose the desired filtering mode. To change the filtering mode, follow the steps below:
1.
First, open ESET Smart Security by clicking the icon in your Windows system tray or by clicking Start → All Programs → Eset → ESET Smart Security.
2.
Switch to Advanced Mode by clicking Toggle Advanced mode in the lower left corner of the main window, or by pressing CTRL + M on your keyboard.
3.
Click Setup → Personal firewall and then click Advanced Personal firewall setup... at the bottom of the main page (See Fig. 1-1 below).
Fig. 1-1
4.
The ESET Smart Security Setup window will appear. From the Filtering Mode drop-down menu on the right, select the desired filtering mode and click OK. (Fig. 1-2 below).
Fig. 1-2
See below for an explanation of each mode.
Automatic mode
The communication is automatically controlled by settings defined by the user. After connecting to a network, the user decides whether it is a trusted zone. Communication in a trusted zone is not limited in both directions. Communication within a restricted zone – the Internet communication - is allowed only for applications establishing outgoing connections. Such applications are trusted also for incoming connections. This mode requires no user interaction (except when connecting to a new network).
In short, Automatic mode uses no predefined rules, but automatically analyzes communication. Applications are allowed to establish outgoing connections. Applications that already established outgoing connections are also trusted for incoming connections.
Interactive mode
The communication is handled according to predefined rules. If there is no rule available for a connection, the user is prompted in a dialog window to allow or deny the connection. After some time, the user will have created a group of rules fitting his or her needs. It is not recommended to select the Interactive mode for each user, since after some time they may ignore the regularly appearing dialog windows and just allow everything they are prompted for by the program.
Policy-based mode
The communication is handled according to rules given by the administrator. If there is no rule available, the connection is automatically blocked and the user sees no warning message. It is recommended to select the Administrator mode only if you are an administrator who intends to control the network communication, and if you are sure you know which applications should be allowed or denied.
Unable to send or receive emails after installing ESET Smart Security
If you are experiencing difficulties sending or receiving email after installing ESET Smart Security, first disable the firewall to see if it is affecting email communication. See the steps below for details:
1.
Open ESET Smart Security by clicking the icon in your Windows system tray or by clicking Start → All Programs → Eset → ESET Smart Security
2.
Switch to Advanced Mode by clicking Toggle Advanced mode in the lower left corner of the main window, or by pressing CTRL + M on your keyboard.
3.
In the left column, click Setup → Personal Firewall → Disable filtering: allow all traffic.
Fig. 1-1
The Firewall is now disabled. Check to see if email can be successfully sent and received.
If the issue is not resolved, the firewall is not the problem. Please verify that:
*
You have an active Internet connection
*
You can send/receive e-mails when accessing your account directly through the website. (ex: http://www.hotmail.com/)
*
Microsoft Outlook has been configured correctly to retrieve your e-mail
*
No other firewall is currently installed
Modifying Personal Firewall Settings
If disabling the firewall resolves the issue, adjustments need to be made to the firewall rules or the rules need to be returned to default. Follow the steps below to adjust the firewall settings.
1.
Open ESET Smart Security.
2. While in Advanced mode, click Setup → Personal firewall and then click Advanced Personal firewall setup... at the bottom of the main page (See Fig. 1-2 below).
Fig. 1-2
NOTE: To Return Personal Firewall Settings To Default, skip to 1 of that section. Otherwise, continue with step 3 immediately below.
3. Select Interactive mode from the Filtering mode drop-down menu.
4. In the left column under Personal firewall, click Rules and Zones.
5. In the Zone and rule editor section, click the Setup button (See Fig. 1-4 below).
