Question about RVS4000 ACL rules

    I am new to the RVS4000. My question concerns the use of ACL rules. I like to setup my firewalls as a "Default Drop Policy" in other words, if incoming traffic does not match a rule, then the packet gets dropped.

    Looking at the default rules built in to the RSV4000 it looks like they open up the firewall to all incoming traffic from the WAN port. The thing that scares me is the default rule that says:

    Enable = Enable
    Action = Allow
    Service = All Services
    Source Interface = WAN
    Source = Any
    Destination = Any
    Time = Any Time
    Day = Everyday

    Am I reading this correct in that it allows all services from the WAN port into the network. If so, how do I go about setting the router up so that everything gets dropped and the only packets allowed are the ones that I specifically allow. This rule cannot be deleted but I am sure their is a work around. Thanks for the help
