I am trying to set up a Fedora-Linux box to serve as a dhcp server, dns
server, smb server and router for a small LAN. The first thing I am trying
to make work is the dhcp server. This server has two NIC's; eth0 is on the
LAN, eth1 is disconnected now. As I get the parts running I will connect
eth1 to the Internet via the DSL modem.
I installed Fedora Core 2 and have applied all the updates as of today.
On my test network there is a DSL router at 192.168.1.1. It works. If I set
a Windows 2000 client to a static IP in the range 192.168.1. and set the
gateway to the router I can access the Internet.
:::::: On the Fedora box I am trying to make the server:
cat dhcpd.conf----------------------------------------------------------
ddns-update-style interim;
ignore client-updates;
# ... Internet side - connects to DSL/Cable modem (disconnected)
subnet 192.168.2.0 netmask 255.255.255.0 { }
# ... LAN Side
