   Has title, if you put a host into the DMZ and apply both IP Filtering and ID does the host in the DMZ get the benifit of this ?, or have i got to find another way to stop ports 135-139 from the WAN side

"Some home routers refer to a DMZ host. A home router DMZ host is a host on the internal network that has all ports exposed, except those ports forwarded otherwise. By definition this is not a true DMZ (Demilitarized Zone), since it alone does not separate the host from the internal network. That is, the DMZ host is able to connect to hosts on the internal network, whereas hosts within a real DMZ are prevented from connecting with the internal network by a firewall that separates them, unless the firewall permits the connection. A firewall may allow this if a host on the internal network first requests a connection to the host within the DMZ." (from Wiki)

 

Other than the IP filtering and ID, you should only limit the ports for the DMZ host instead of open all the ports.  Just follow and fill in the router setting for the DMZ host, and firewall Port Forward or Port Triggering settings on the router.
