DHCP Server, Shorewall, IP Forwarding help

[adam stokes]

Outline : Server w/ 2 nics, Workstation on local network., Shorewall 
firewall for IP Masq, DHCP Server
Problem : Not able to ping outside local network from workstation.

What does work:
DHCP server setup and hands out Lan IP's defined through the range in 
dhcpd.conf
Server can ping outside network
Workstation can ping server
Have used sample configs for Shorewall which outline my lan setup.
I have checked to make sure IP Forwarding is turned on, and that 
iptables,shorewall, and dhcp server are started, ifconfig on server 
shows eth0 bounded to the ISP and eth1 bounded to lan ip given out by 
dhcp server.
IFConfig on workstation shows IP given out by DHCP server as well.

I am lost at what else to look at to try and get my workstation to 
properly connect to the internet through the dhcp server :(

Only thing i really dont understand is the DNS Options to set in 
dhcpd.conf so im not sure how important that is since the dns should be 
resolving from the ISP which the resolv.conf on the server shows that.

So any help as to directions to look at would be appreciated
