    Hi,

    I have the CSF - ConfigServer Firewall installed at the last two years with any problem, but now, I have many problems.

    My server going DOWN or MANUAL REBOOT many times by hour...

    I make Ticket Support Helpdesk to SoftLayer, but I dont't have an great help.

    And if you may... help me please ?

    I need help to configure de rules or iptables ......

    ====================================================

    Transcrition of Ticket Support:


    This was the message, we got from the server logs before the server reboot.
    ==========================
    Sep 6 12:01:11 server5 kernel: Firewall: *UDP_OUT Blocked* IN= OUT=eth1 SRC=XXX.XXX.XXX.XXX DST=213.30.10.26 LEN=300 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=53 DPT=41094 LEN=280
    ==========================


    The firewall rules (csf) configured in the server were causing the issue. We could see the following firewall messages via the console.

    ==========================

    Firewall: *UDP_OUT Blocked* IN= OUT=eth1 SRC=75.XXX.XXX.XXX DST=83.174.45.162 L
    Firewall: *ICMP_IN Blocked* IN=eth1 OUT= MAC=00:30:48:8d:d5:c5:00:1a:30:38:00:0

    ==========================

    Now you may please re-configure the rules in the firewall service.

    Please configure the rules properly from your end to avoid this issue happening again.



    ====================================================

    How I make this ?

    Regards,

    Joao


    PS - Sorry with my english.
