    Iptables DNS Resolve Problem....in CHROOT

    Hi Everyone

    i am trying to execute the the iptables rule

    iptables -t mangle -I PREROUTING -d google.com -j ACCEPT

    its give error...

    Code:
    [root@manage /root]#chroot /var/iptablespackaging/ sbin/iptables -t mangle -I PREROUTING -d google.com -j ACCEPT
iptables v1.4.10: host/network `google.com' not found
Try `iptables -h' or 'iptables --help' for more information.

    for that my DNS is also correct
    Code:
    [root@manage /root]# vi /etc/resolv.conf 
nameserver      203.88.135.194
nameserver      127.0.0.1


    MY ALL IPTABLES RULES IS WORKING BUT just this rule is not going to work...

    i have take STRACE command output...

    Code:
    [root@manage /root]# chroot /var/iptablespackaging/ sbin/iptables -t mangle -I PREROUTING -d google.com -j ACCEPT
iptables v1.4.10: host/network `google.com' not found
Try `iptables -h' or 'iptables --help' for more information.
[root@manage /root]# strace chroot /var/iptablespackaging/ sbin/iptables -t mangle -I PREROUTING -d google.com -j ACCEPT
