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.
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 then complete the steps in this Knowledgebase article to resolve your connection issues.
