M4300 ACL Help - Multicast traffic ignoring ACL
Hey Team,
I want to make a VLAN where clients can only communicate with the gateway and not each other. This is often called 'private VLAN' or 'client isolation'.
I'm attempting to do this with MAC ACL's.
I have two ACLs, each ACL has one rule:
- GUEST-IN (assigned to inbound)
- DST MAC = AA:BB:CC:DD:EE:FF/00:00:00:00:00:00
- GUEST-OUT (assigned to outbound)
- SRC MAC = AA:BB:CC:DD:EE:FF/00:00:00:00:00:00
The ACLs are bound to a client interface and appear to be working for unicast traffic, but not multicast traffic... have I missed something?

The Netgear Managed Switches offer full support for Private VLAN, including the three industry common Private-VLAN Types (Primary, Isolated, Community). Consult eg. the M4300 Intelligent Edge Series Fully Managed Stackable Switches Software Version 12.0.8 Software Administration Manual, Private VLANs, p.61 ff.
