Figure 1-14. Setting up VLANs to Ensure the Firewall Checks Wireless Traffic
ACLs. In addition to screening traffic for signs of an attack, the Wireless Edge
Services zl Module’s firewall can enforce policies that you create. These policies are
called ACLs, and they affect traffic inbound on an interface.
Note IP ACLs applied to VLAN interfaces only affect traffic routed to another VLAN.
ACLs applied to physical interfaces affect all inbound traffic.
You can create the following types of ACLs:
■ MAC standard ACLs
■ MAC extended ACLs
■ standard IP ACLs
■ extended IP ACLs
As discussed in “MAC Authentication” on page 1-27, MAC standard ACLs filter
traffic according to the source MAC address. These ACLs act as authentication:
rather than control which network services a user can access, MAC ACLs either allow
or block traffic from a station entirely.
