    Client Machine Ping command not wrking


    I am using redhat 6 64bit server OS in my concern. I am configure squid proxy server. My interconnection is dhcp connectioned ip address and i am changed to static ip address using squid proxy.
    For Example: i am getting dhcp connection from Ethernet eth0 ( for input and sending information to another Ethernet eth1 ( for output to my client machine like Xp.
    My problem is i can't ping google or some other websites using cmd prompt.But internet was working properly
    And also used iptables entry i post below please tell right way to rectify this problem

    :INPUT ACCEPT [0:0]
    :OUTPUT ACCEPT [0:0]
    -A INPUT -i eth1 -p all -s -j ACCEPT
    #-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
    # allow certain inbound ICMP types (ping, traceroute..
    -A INPUT -i eth0 -p icmp --icmp-type destination-unreachable -j ACCEPT
    -A INPUT -i eth0 -p icmp --icmp-type time-exceeded -j ACCEPT
    -A INPUT -i eth0 -p icmp --icmp-type echo-reply -j ACCEPT
    -A INPUT -i eth0 -p icmp --icmp-type echo-request -j ACCEPT
    #Common ICMP (PING) Match Criteria
    -A OUTPUT -p icmp --icmp-type echo-request -j ACCEPT
    -A INPUT -p icmp --icmp-type echo-reply -j ACCEPT
    #Enable Ping Request
    -A INPUT -p icmp --icmp-type 8 -s 0/0 -d -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT
    -A OUTPUT -p icmp --icmp-type 0 -s -d 0/0 -m state --state ESTABLISHED,RELATED -j ACCEPT
