Thread: issue reg NATing using iptables

  1. issue reg NATing using iptables

    Greetings ,

    I am trying to configure NATing with iptables on Fedora Core 6 box
    with NICs.

    For this I am trying to execute the command.
    iptables -t NAT -A POSTROUTING -o eth0 -j MASQUERADE

    But it gives me the following error.

    ""
    iptables v1.3.8: can't initialize iptables table `NAT': Table does
    not exist (do you need to insmod?) Perhaps iptables or your kernel
    needs to be upgraded.
    ""

    I loaded the following modules .

    iptable_nat 11845 0
    ip_nat 22253 2 ipt_MASQUERADE,iptable_nat
    ip_conntrack 56993 5

    ipt_MASQUERADE,iptable_nat,ip_nat,ip_conntrack_net bios_ns,xt_state
    nfnetlink 11353 2 ip_nat,ip_conntrack
    ip_tables 17669 2 iptable_nat,iptable_filter
    x_tables 18501 8
    ipt_MASQUERADE,iptable_nat,ipt_REJECT,xt_state,ip_ tables,ip6t_REJECT,xt_tcpudp,ip6_tables


    After loading the modules , I am still getting the same error.

    Please tell me where I am wrong. Do I have to install more modules ,
    if then please
    let me know the name of the modules.

    With thanks in Advance

    iptables -t nat

    (lower case)

    should do the trick.
