Fixing Internet Access Issues | Router ACL Troubleshooting & Resolution | CertBlaster
In this video, we are fixing internet connectivity problems on a workstation due to an incorrectly configured router access control list (ACL). Having confirmed IP settings and successful pings to the gateway and destination website, we realize that HTTP and HTTPS ports (80 and 443) are being blocked by the ACL on the router. By deleting the erroneous rule, we restore normal web access, verifying the repair by visiting the site through a browser. This step-by-step process is ideal for anyone learning hands-on network troubleshooting and ACL management.
