Hi @RahulPrasadh, As @RaphaelL mentioned, pings should not be used to test whether a content filtering rule is working as intended as content filtering does not apply to ICMP traffic. That being said, if an allow-listed URL is still being blocked, then there are three likely possibilities: The content filtering configuration is incorrect or insufficient. Something else on the MX is blocking the traffic. The traffic is blocked/dropped somewhere else before or after the traffic is processed by the MX. To determine which possibility is occurring, I would first recommend checking whether the traffic is in fact being blocked by content filtering, which can be done by navigating to Network-wide > Event log and filtering for the affected client, setting the appropriate time, and including the Event type Content filtering blocked URL. If you see entries for a URL that are related to the resource the client is attempting to reach, then ensure they have been properly added to the Content filtering Allow list. https://documentation.meraki.com/MX/Content_Filtering_and_Threat_Protection/Content_Filtering/Content_Filtering_Troubleshooting#Allow_URL_list_patterns_are_not_being_allowed If the traffic is not being blocked by content filtering, I would recommend checking any layer 3 and layer 7 firewall rules. If your MX is running version 18.2+, you can use the firewall logging tool to see in real time if any configured rules are traffic. https://documentation.meraki.com/MX/Firewall_and_Traffic_Shaping/Firewall_Logging
