In setting up Firewall rules, whats the specific reason that there are
separate rule lists for LAN, WAN, OPT1 interfaces? Afterall, aren't i
defining the interface implied when I specify the SOURCE and DESTINATION
interface in the rule itself?
It seems redundant, and, at times, conflicting: What would be the purpose
of say setting up a rule that allowed traffic between LAN and WAN but
applying it to the tab under the OPT1 interface for example.
Am i missing something?
