Possible DHCP server and gateway (got DHCP server working though)

I would like to know the best tutorial for setting up a decent DHCP server for some kind of maybe hardware firewall?

I have setup the DHCP server though to get it on my Linux box using Centos v4 but thats all I have done.

Cant believe how simple it really was, here's my config anyways:

Code:

#
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp*/dhcpd.conf.sample  
#
ddns-update-style interim;
ignore client-updates;

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 nis-domain		"hsmedia.co.uk";
	option domain-name		"hsmedia.co.uk";
	option domain-name-servers	192.168.0.2;

	option time-offset		-18000;	# Eastern Standard Time
#	option ntp-servers		192.168.1.1;
#	option netbios-name-servers	192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
#	option netbios-node-type 2;

	range dynamic-bootp 192.168.0.128 192.168.0.254;
	default-lease-time 21600;
	max-lease-time 43200;

	# we want the nameserver to appear at a fixed address
	host ns {
		next-server hsmedia.co.uk;
		hardware ethernet 00:06:4F:65:D7:AF;
		fixed-address 192.168.0.2;
	}
}

Is this the best way to do the DHCP server part, how would I secure websites being received by the server, ie to help prevent malicious attacks on my work computers so they dont get hacked, ie using some kind of hardware firewall?

I would really appreciate how to firm this system up so I can not have to bother with firewalls on my computer preferably.

I look forward to your replies,
Jeremy.

 

I have sorted it.

Just used an example off the web for the proper dhcp configurations.

This one wasnt behaving (the example above), the way I wanted it to, but it is now.

Thanks for everyone whos had a look and tried something out though, but just wanted to close this post.

Kind regards,
Jeremy.
