MAP 6.5 toolkit firewall needed ports???????

i've read the getting started guide tha's with the MAP toolkit but the firewall section is totally misleading. as it says that it needs to have ports 139, 445, 135 TCP and 137, 138 UDP . but when i use these ports only it fails and tells me that "RPC esrver unavailable", i knew later that TCP 135 has to have a dynamic range opened to be able to communicate over RPC.

so can anyone that has implemented MAP toolkit with firewall between VLANs help me with the real required ports and their directions, are they needed from the MAP computer to the clients or vice versa or two way??????

pleeeeeeeeeease help..

thanks in advance.
