    Perplexing problem??? ifconfig - dhcpd -

    Hello all,

    I'm hoping some linux guru could help me here.

    Here is my question.

    ~If I do an ifconfig and see 2 physical interfaces of eth0 w/ ip of say /16 and I see an eth1 of say some public ip range "12.x.x.x /x

    And the server also is dhcp server dishing out IP's with a subnet pool of ( /24) - and all clients are receiving this network range.

    How is this possible if I see no physical interface when doing "ifconfig"?
    -There are no subinterfaces at all.

    I took a look in iptables but only see some SNAT going on.

    ANYONE HAVE AN IDEA how this is possible? What am I not thinking or not knowing about?

    please show us a:

    cat /etc/network/interfaces
    I would expect that the output would answer your question.

    thats only applicable for debian based distros

    I'm not sure i quite get the question you are asking, is it about the range of addresses being supplied by dhcp?

    post output of
    /sbin/route -n
    and also show us your dhcpd.conf file
