I'm trying to turn my debian box into nat server. So far, I've got the
kernel configured with all the netfilter stuff that the IP
Masquerade-howto on tldp.org said (I'm running 2.4.24, with sarge/sid).
I've installed dhcpd and it seems to run fine.
So here's my problem: my laptop (which has a dhcp client thats works on
campus) can ping my deskstop but that's all. It can't reach the net.
I have done the echo 1 >/proc/sys/net/ipv4/ip_forward thing to turn it
on and still nothing. So here is my dhcp.conf and my
/etc/network/interface file snippets. ANY help would be greatly
appreciated.

king:/proc/sys/net/ipv4# more /etc/dhcpd.conf
#
# Sample configuration file for ISC dhcpd for Debian
#
# $Id: dhcpd.conf,v 1.4.2.2 2002/07/10 03:50:33 peloy Exp $
#

# option definitions common to all supported networks...
option domain-name "mytalon.com";
#option domain-name-servers king.mytalon.com;

option subnet-mask 255.255.255.0;
default-lease-time 600;
max-lease-time 7200;

#my declared subnet for eth1
subnet 192.168.0.0 netmask 255.255.255.0 {
 range 192.168.0.1 192.168.0.10;
 option broadcast-address 192.168.0.255;
# option routers prelude.fugue.com;
}

king:/proc/sys/net/ipv4# more /etc/network/interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian
installation
auto eth0
iface eth0 inet dhcp

#Second network card - 3Com vortex
auto eth1
iface eth1 inet static
       address 192.168.0.1
       netmask 255.255.255.0
       network 192.168.0.0
       broadcast 192.168.0.255

Something else that I don't completely understand (this is my first time
ever creating a network) is that my laptop picks up 192.168.2.1 from
DHCPACK when ifup eth0. Shouldn't it receive on 192.168.0.1?

thanks,

Uzoma
