    I don't see any real benefit of segmenting the LAN addresses.  You can use the interface object to define traffic specific coming in/out of the firewall.  Is there some type of rule that you are trying to create that you can't by using only the network object?

    Hello Mike.

    Thank you for your reply. I am sorry but the client decided on not using FWB.

    They were asking if  it  would be an increase in security if the LAN machines would deny traffic from the router since they are all accessing the internet via a single firewall machine that allows internet access.
    Allowing - would give LAN inter communications but deny any router

    Thanks again.
