the "0"is only to indentificate the subnet.
DHCP Server isn't installed on ISA Computer.
But, I've VPN support enabled in ISA. I think the RRAS provide DHCP 
Funcionatily.
 
Also, OWA with SSL.(could it be the problem ?). 
 
My external ip address is 200.206.32.10 , mask 255.255.255.192 (only web card 
in ISA).
In my DNS Server , I've a "A" record that appoint to isa Server, like 
www.mysite.com 
 
Isa server has a DMZ card, 192.168.0.1 , mask 255.255.255.0.
 
Web Server has 192.168.0.10 , mask 255.255.255.0. ISA ping the web Server.

No, I said "DHCP Server", not DHCP filter.  You have the DHCP server service 
running on the ISA.
Unless ISA is providing DHCP services to the internal network, remove it.
No address ending in "0" is a valid host IP, but since you didn't provide your 
external IP and Netmask, I can't tell if 192.168.0.x is a subnet of your 
external network.

no, only LAT nic (10.1.1.0) reference is in LAT.
DHCP filter has deleted.
 
192.168.0.0 isn't a valid external address. maybe is it ?

That entry has nothng to do with the error you're seeing; it's the DHCP server 
service on the ISA trying to detect "rogue" DHCP servers.
Is the DMZ range in the LAT?
Third-leg DMZ must be a subnet of the ISA external IP.  It doesn't look as if 
that's the case.

Perimeter Network) and I can't to access my Web Server from Internet.
The Web Browser shows "403 - Forbidden. Isa server denies ... "
 
I opened IPxxxlog.txt and saw the following events:
 
 
Time     IP Source   Mask                   Protocol Source Port  target Port 
Action 
 
(time)    127.0.0.1   255.255.255.255      Udp        68                  67    
    BLOCKED

ISA rules should apply to DMZ requests as well.
What is your configuration?
