Hello. I was trying to diagnose potential connectivity problems with my Meraki Wireless Access Points. I have rules set up on my firewall to allow my Meraki APs out to the Meraki cloud, and I see no denials. However, I see a great deal of traffic originating from the Meraki cloud (188.8.131.52) over port udp 7351 being denied at my gateway. It shouldn't be return traffic, since that is allowed. Does anyone know what this is? Traffic is below.
My public interface address
Thank you and I understand that. Again, this isn't reply traffic. This is traffic originating from the Meraki cloud that is being sent to my public gateway address. I followed all the Meraki firewall rules, and all my outbound traffic to the Meraki cloud is being allowed.
@hfc_jzitnik there shouldn't be any traffic initiated from the Meraki cloud, it should only be return traffic. Is there a possibility that your firewall is incorrectly identifying the return UDP traffic since UDP is connectionless?
If it really is not return traffic then I'd open a case with support to get their take on what's happening.
