How security policy - intrazone works?

Trying to use a Security policy with type intrazone and action is Deny (any application & service).

Target is to block all communication within the same zone (subnet). Such as ping, file share (smb), ftp, etc.

The layer3 interface and the computers were connected to a unmanaged switch.

 

But the outcome is only the gateway (layer3 interface) cannot be contact. All the computers can still comunicate with each other.

Your devices are on the same broadcast domain so they do not need to pass through the PA interface to communicate with each other.

 

search this site for “intrazone”.

Hosts on the same subnet never see the firewall.

 

Intrazone seperates different subnets from each other, and requires that the firewall is the Gateway for these subnets.

You could segregate traffic within the same subnet using L2 or vwire interfaces and inspect the traffic using intra-zone rules.

Hello JoeAndreini,

This seems impractical. I'll have huge workload to assign each computer to has its own L2 interface.
