LinuxQuestions.org - DHCP issues on quad-NIC box

Hello, I'm rather new to the whole networking shebang, but I'm having a go anyway ;)

I have a box with a D-Link DFE-580TX card (four ports) with one port, eth2, connected to a DSL router for internet access. The intention is to eventually set it up as a squid/firewall/clamav/traffic shaper box. I'm using Mandriva 2006.

I need DHCP the other three ports (eth0, eth1 and eth3) so that clients can connect, and this is where the problem starts. dhcpd starts with no error messages at all, but only clients on eth1 can connect.

Here are the configuration files I've been playing with:

/etc/dhcpd.conf:

Code:

ddns-update-style none;



# eth3, LAN

subnet 192.168.0.0 netmask 255.255.255.0 {

        # default gateway

        option routers 192.168.0.1;

        option subnet-mask 255.255.255.0;



        option domain-name "localhost";

        option domain-name-servers 10.0.0.2;



        range dynamic-bootp 192.168.0.16 192.168.0.253;

        default-lease-time 21600;

        max-lease-time 43200;

}



# eth1, DMZ

subnet 192.168.1.0 netmask 255.255.255.0 {

        # default gateway

        option routers 192.168.1.1;

        option subnet-mask 255.255.255.0;



        option domain-name "localhost";

        option domain-name-servers 10.0.0.2;



        range dynamic-bootp 192.168.1.16 192.168.1.253;

        default-lease-time 21600;

        max-lease-time 43200;

}



# eth0, WiFi

subnet 192.168.2.0 netmask 255.255.255.0 {

        # default gateway

        option routers 192.168.2.1;

        option subnet-mask 255.255.255.0;



        option domain-name "localhost";

        option domain-name-servers 10.0.0.2;



        range dynamic-bootp 192.168.2.16 192.168.2.253;

        default-lease-time 21600;

        max-lease-time 43200;

}

/etc/sysconfig/dhcpd :

I have no idea of what could be causing this behaviour. Any help is much apreciated.

Cheers!
