    Have a problem after delete firewall

    Hello every one

    My server is too slow

    and when I tracert it I get timed out in all hubs

    so I go and delete APF firewall in this way

    /etc/init.d/apf stop

    iptables -F

    rm -Rf /etc/apf

    rm -Rf /etc/rc.d/init.d/apf

    rm -Rf /var/log/apf_log

    rm -Rf /var/log/apfados_log

    rm -Rf /usr/local/sbin/apf

    /sbin/chkconfig --level 345 apf off

    pico /etc/cron.daily/fw

    #delete

    /etc/rc.d/init.d/apf restart >> /dev/null 2>&1


    --------------------------------------------------------

    Then reboor server and network

    Now

    iptables -L
    [email protected] [~]# iptables -L
    Chain INPUT (policy ACCEPT)
    target prot opt source destination

    Chain FORWARD (policy ACCEPT)
    target prot opt source destination

    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination

    Chain acctboth (0 references)
    target prot opt source destination


    ---------------

    But when I try to ping this server from out side I always get timed out

    and when I try to ping anything from this server

    [email protected] [~]# ping google.com

    ----- it is working ok with yahoo - google - hotmail

    the server is too slow

    and when I asked DC to change IPs

    they told me

    This looks to be a firewall on your local server that is causing this issue.

    and I told him that firewall is deleted

    they don't care

    How I can solve this please ???

    Well when you ping 127.0.0.1 if it is giving problems with packetloss.

    Its relating to the datacenter, ask them to fix it.

    Well you have no firewall policys.

    If iptables -F did/doesn't fix it then its down to your datacenter.
