To know that it worked
before is a quite important comment.
However, I think if you
want to NAT from untrusted to dmz you should investigate rules.
Policies should not have
anything to do with it since this would globally open dmz for untrusted without
a chance to influence proto and port.

I never set routing between them, but it previous
work find.
I mean they can access one server by one public address.
I think I have to check policy and rules.

If loc can access wan this is because you have
a default route (0.0.0.0/0) from loc clients to loc interface and from
firewall to wan-router (normally provided by your isp)
If loc can access dmz this is either because
dmz clients have a static route back to loc or a default route to firewalls
dmz interface (since loc has a default route there is no need to describe the
way to the dmz but a need to explain your dmz to return, this can be done by
static or default route)
If dmz has default route to firewalls dmz
interface than routing is fine. In this case I guess rules or policy is
wrong.
In internal can access public ip (what do you
mean? Public wan oder publc dmz?) this say nothing about why dmz is not
working.

Either you maybe do only have a static
route between dmz clients and loc but no default route or maybe something
is wrong with your rules or policies.
Does your policy file logs all all
drop and net all drop? If yes, what do you see in your messages?
Cheers

DMZ can't access to internet
Hello
We are using old version ( shorewall-3.0.7-1) with Centos 5.3
The shorewall has three zones (net / loc / dmz).
Loc can access to internet with no problem and can access to DMZ.
DMZ can't access to internet.
Net can't access to DMZ with NAT.
I tried to restart the machine / check Lan card / check cable , they were
work find.
Is it DMZ Lan card problem? but it can start at Centos ...
Thanks !!
