    Use the CBQ functionality!
       Setup CBQ:
    To allow web access to the specified router interface(s) from a specific IP
    (s)  
    
    To drop packets to all router interfaces 
    Ex CBQ 1 = WAN in
    -Block ALL traffic 
    add cbq.1 traffic-class.Deny-default parent root-input-tree bandwidth-
    allocation 0 bounded true
    
    -allow HTTP traffic from WAN in
    add cbq.1 traffic-class.httpWANin parent root-input-tree bandwidth-
    allocation 1000000 bounded true dest-ip-addresses (IP's here) application 
    http row-status active
    
    -allow Return Flow out - established TRAFFIC
    add cbq.1 traffic-class.httpWANreturn parent root-output-tree bandwidth-
    allocation 1000000 bounded true dest-ip-addresses (IP's here) application 
    httpEstablished row-status active
    
    -Block ALL traffic to router interface
    add cbq.1 traffic-class.BlockRouterIPAccess parent root-input-tree 
    bandwidth-allocation 0 bounded true peer-classification-order 90 dest-ip-
    Addresses xxx.xxx.xxx.xxx,xxx.xxx.xxx.xxxx row-status active
    
    add cbq.1 traffic-class.AllowWebMange parent root-input-tree bandwidth-
    allocation 64000 bounded true peer-classification-order 40 src-ip-
    Addresses xxx.xxx.xxx.xxx dest-ip-addresses xxx.xxx.xxxx application http 
    row-status active
