Hi Marki,

Looking at your setup, everything is working as you have connected it
although it may not be what you expected.

Your firewall is connected to management Vlans and it received a packet
that was sourced from the management Vlan on a different interface.
Therefore, the logic in the firewall blocked it.

We have a firewall that works the same way...as designed by the firewall
vendor. Also, the switch with a routed interface is working as designed.

Not sure exactly what you are trying to do and there are several variables
to consider but your logic and design needs to be tweaked a little to get
the desired results. Contact GTAC, those guys are great and can help you.
