RC1: Traffic Graph Size/Interface bug
Using RC1(switched over from Monowall to see how pfSense had progressed since the last time I'd tried it)
An interface bug more than anything else:
When viewing the traffic graph, all looks good. If I change the size of the graph, everything still looks as it should, but it defaults me back over to the WAN interface. If I change the Interface back to my DMZ interface, it changes the size of the graph back to the default.
We removed that feature for now in the upcoming RC2. It will be fixed in a later release.
