Hello,
a few questions to clarify what you want:
a) only access to "internet" and to the VLAN "Shared Services"
--> who should be able to access the Internet and the VLAN "Shared Services" ?
b) Vlan restricting communikation between VLANs
--> do you want to configure a VACL so that no VLAN can talk to any other VLAN ?
c) the Systemmanagement and Netzwerkmanagement Vlan without any restriction
--> these two VLANs should be able to talk to each other without restriction, but to no other VLAN ?
What have you configured so far, how does your VACL look so far ?
Regards,
Georg
