I have a Meraki MX90 behind a Ubnt EdgeRouter. The Meraki has a public IP on the WAN side so I figured the EdgeRouter didn't have NAT turned on. How ever when I go to NAT, I have the default "masquerade to eth0" rule. (eth0 is my WAN port)
show nat rules
returns the default
MASQ eth0 saddr ANY to xx.213.214.137
rule. Any ideas as to how traffic can be getting through un-NATed? What else should I be looking for?
