Inside to Inside Logs

[keithcclark71]

I can't think of a reason why the Gateway firewall would be logging Inside to Inside as shown in the below. Any ideas why I would be seeing these logs for same subnet traffic flows on a gateway firewall? In screenshot you cant really see but it does say Ingress Security Zone Inside and Egress security Zone Inside

Is 192.168.0.0 a /16 in that network or are their smaller subnets masked out? If the latter, they could be using the firewall as a gateway. If not, then perhaps a packet capture would shine some light on why it is happening.
