  1. Firewall & NAT

    am not able to setup a firwall box which will transmit internet
    packets from internal network to the internet and otherway. Could you
    please guide me what i am missing here and where I am going wrong?

    [internet] ----(public ip)---[cable modem]( 192.168.1.1)------(
    192.168.1.51)[solaris 10 x86 f/w box](
    192.168.0.52)------[router]------(ip: 192.168.0.105/gw:192.168.0.52 )
    [PC]





    On solaris box: I can ping 192.168.1.51 , 192.168.0.52, 192.168.1.1 &
    Internet

    >From PC I am able to ping 192.168.1.51 to 192.168.0.52 but NOT

    192.168.1.1 or internet.



    Routing table is :



    # netstat -rn



    Routing Table: IPv4

    Destination Gateway Flags Ref Use Interface

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

    192.168.0.0 192.168.0.52 U 1 2 rtls1

    192.168.1.0 192.168.1.51 U 1 8 rtls0

    224.0.0.0 192.168.1.51 U 1 0 rtls0

    default 192.168.1.1 UG 1 13

    127.0.0.1 127.0.0.1 UH 3 24 lo0



    # ndd -get /dev/ip ip_forwarding

    Thanks in advance :-)

    Assuming c0d0 is the disk on which Solaris is installed, then the
    latest version of Solaris 10 (i.e., 1/06) uses GRUB.

    Yep. Of course, just watching the machine boot will confirm this
    for sure.
