How to troubleshoot firewall problems.
If you’re having problems with your firewall, there are a few things you can do to try and troubleshoot the issue. First, make sure that the firewall is turned on and that it’s properly configured. If you’re not sure how to do this, consult your firewall’s documentation or contact your ISP.
If your firewall is on and properly configured, the next step is to check your router. Sometimes, routers can be configured to block certain types of traffic, such as certain ports or IP addresses. If you think this might be the case, try temporarily disabling your router’s firewall and seeing if that fixes the problem.
If you’re still having issues, the next step is to check your computer for any malware. Malware can sometimes interfere with firewalls and cause them to block legitimate traffic. Run a full scan of your computer with your anti-malware software and remove any malware that is found.
Finally, if you’re still having problems, contact your firewall manufacturer or ISP for help. They should be able to help you troubleshoot the problem and get your firewall up and running properly..Extra resources
