Hi,They are all transparent.What you see I believe is just the fact that the traffic on WAN (aggregation of all other interfaces/VLANs towards internet) has highe throughput in order to show it on a graph the Y axis need to be adjusted to accommodate that so the Steps on Y are bigger than is the ratio on the other interfaces.Look at the graphs again, you can see that the max throughput at the time is 700Kbit, but WAN actually receives 25MbitRegards,S.
