Meraki Firewall Rule

[Hmuet]

Hi everybody, 

I try to deny a ping between first vlan and second vlan, but nothing it doesn't run. After save the rule when i test the ping, it work again.

Please need any help

After you apply a fw rule, you need to make sure the flow (stop the ping) is not active for 10 minutes. 

On the live tools you can see start live fw logging to see what rule(s) it hit.  So start log > then start ping

Hi @Hmuet,

I agree with @ww, the firewall rule is based on flow hence wait a 5-10 minutes after the rule is applied so that the preexisting flow expires and new ones from the client get processed by the firewall. Also, ensure the configs are up to date on the Security & SD-WAN > Appliance status page after the rule was added.
