    Hi,

    Some packets from the DNS of my ISP are blocked :
    Code:
    27/09/11,09:53:16  D-16   'Block : All other packet' 212.27.40.241     UDP       Ports Dest:55821 Src:domain=53
    27/09/11,09:53:17  D-17   'Block : All other packet' 212.27.40.241     UDP       Ports Dest:55821 Src:domain=53
    27/09/11,09:53:18  D-18   'Block : All other packet' 212.27.40.240     UDP       Ports Dest:55821 Src:domain=53
    27/09/11,09:53:21  D-19   'Block : All other packet' 212.27.40.241     UDP       Ports Dest:55821 Src:domain=53
    27/09/11,09:53:21  D-20   'Block : All other packet' 212.27.40.240     UDP       Ports Dest:55821 Src:domain=53
    27/09/11,09:53:22  D-21   'Block : All other packet' 212.27.40.240     UDP       Ports Dest:55821 Src:domain=53
    
    IP 212.27.40.240 are DNS of my ISP.
    Are these blocking normal?

    These are normal if you using stateful DNS rules.
