Firewall Configuration 7
The Firewall table is an access list that filters packets by denying or permitting access from source
hosts to destination hosts. The rules are applied according to the order set in each entry in the list.
The first match determines whether or not the packet is accepted or denied by the router. If a packet
passes a first match and is not denied access, subsequent rules are applied on the packet. The default
access setting is to deny all access.
