iptables

I currently have 3 machines:

CentOS (router) eth1 - 18.0.168.1 eth2 - 145.165.34.1
Windows Server 2008 (server) 18.0.168.2

DHCP scope - 145.165.34.10 - 145.165.34.20

Windows 7 (client)
- Supposed to use DHCP

I can't get my Windows 7 client to get an address from the Windows Server 2008 DHCP server.

Every network interface can ping each other (ex. 18.0.168.2 can ping 18.0.168.1 & 145.165.34.1 and the other way around).

My Linux machine acting as the router has default IP tables. Other than this command which may or may not be right:

iptables -I INPUT -p udp -d 18.0.168.2 --dport 67:68 -j ACCEPT

I have also tried it after I flushed the IP tables.

I was looking at the dhcrelay command but it seems CentOS doesn't have it and I am not even sure how to use it.
