Packet capture

Hello i´m playing with packet capture on my MR18 to try to see the traffic from a meraki NAT/DHCP network to my router. The problem i´m having is that i can not see the traffic from between my L3 switch to my router.

 

Setup is like this: Router > L3 Switch >  Switch > MR18

Re: Packet capture

You are using the SSID option where the SSID is configured to use NAT?

 

If so, the MR18 processes the DHCP traffic, not your router.

Re: Packet capture

Yes i am using the Meraki NAT option.

I am essentially trying to see the internet traffic that passes from between the MR18 and my router.

@ww should be right, you should be able to do a packet capture on the wired interface of the MR18. Note that because the traffic has already been NATed you'll only see traffic to and from the MR18 IP address.
