What are you doing/trying when you ''get host unreachable''?

The above rules are just silly. DHCP uses broadcast which will not be
routed between the two zones.

What do you mean by ''server''? If the
''server'' is a system in the DMZ
then you need to run dhcrelay on the firewall and set the
''dhcp'' option
on both eth1 and on eth2.

If the DHCP server is running on a server in the DMZ, install and
configure dhcrelay on the firewall. Testing with Shorewall cleared
(''shorewall clear''). Only report back here if you get dhcrelay
working
correctly without Shorewall but you have problems when you start
Shorewall again.
If the DHCP server is running on the firewall system (where Shorewall is
running) then be sure that your DHCP configuration is correct and that
the server is configured to serve eth1 (and that eth1 is in fact the
interface that is cabled to the LAN). If that all looks correct, then
please submit another report following the instructions at
