2500 router and DHCP

I have a PIX which is my dhcp server putting out 192.168.1.150/24 on up addresses. I also have a cisco 2500 with 2 eth ports. I need to forward the dhcp addresses through my router. My PIX is setup and working correctly, i can get on the internet and whatever if my PC is directly connected to it. All i need is the configuration to put in my router so it will forward the DHCP through it to my PC. Currently I have my WAN into my PIX, PIX into eth0 ( 2500 ), eth1 into a catalyst switch, and PC into switch.
