As an alternative to disabling the firewall, you can create a rule to open all connections through TCP and UDP. Using this method the Intrusion Detection System (IDS) will remain active but the ESET Firewall will not interrupt regular web browsing. We recommend that you leave the firewall active at all times except when diagnosing/troubleshooting system problems.
To troubleshoot your connection issues, follow the steps below to pause the firewall. With the firewall paused, attempt to re-connect the device or open the application that is not working properly.
Click Setup → Network protection.
Click the toggle next to Firewall.
Select Pause until reboot and click Apply. The ESET Firewall will remain paused until the next time you restart your computer.
While the ESET Firewall is paused, the protection status will turn red to indicate that maximum protection is not ensured and your computer is vulnerable to threats.
If you are diagnosing potential firewall issues, attempt to connect the device or use the application that is not working properly. If you are successful, your issue is related to the firewall. Re-enable your firewall and resolve your connection issues.
Press the F5 key to open Advanced setup.
Click Network Protection → Firewall. In the Filtering mode drop-down menu, select Interactive mode.
Expand Advanced, and next to Rules click Edit.
Click Add. In the Name field, type a name for your rule. In the Direction drop-down menu, select Both. In the Action drop-down menu, select Allow and click OK.
Select the check box next to Show built in (predefined) rules and select the rule you created in step 5.
Click the up arrow. This will move your rule to the top and ensure that it is enforced.
Click OK to save your changes.
Click Setup → Network protection.
Click the toggle next to Firewall.
Select Disable permanently and click Apply. When you have finished testing or troubleshooting, proceed to the next section to re-enable the firewall. The protection status color will not change to red, although your computer will be at risk while the firewall is disabled.
Click Setup → Network protection.
Click the toggle next to Firewall. The firewall status is now Enabled.
