Oh damn, 

It is a http://www.hotbrick.com/produto.asp?tipo=2&codPro=22 . Do you
think I am out of luck achieving this?

 

One more thing, after doing the registry settings I couldn't connect to
exchange from von which I used too. So I deleted the reg key and
restarted exchange system attendant and it fine for now. Any idea?

Hi Ara,

 

If the ISA firewall is behind a NAT device, you're at the mercy of the
intelligence (or lack thereof) of that devices RPC awareness. Unless
you're using a front end ISA firewall, its probably no more intelligent
than a mere PIX, which means, not much.

 

HTH,

Tom

         Dear Tom,

         

        Following your wonderful article posted on
http://isaserver.org/pages/article_p.asp?id=1325 

        1.      I have checked to see if my isp block port 135. when I
type the telnet <ip> 135 I get a response back so it should be fine 
        2.      ISA is behind a nat device, so I forwarded tcp 135 to
external face of ISA 
        3.      did what you suggested for adding registry key to
exchange and restarted IIS admin service and exchange system attendant
which restarted depending services too 
        4.      created the exchange rpc rule 
        5.      Created an outlook profile, but every time I load the
outlook I get the connection to Microsoft exchange server is
unavailable. Outlook must be online or connected to complete this action

        6.      I monitor ISA logs from my home ip address and the only
thing shows up is  ISA    -                       TCP      -
-                                               3647     63         0
228       0x80074e24                         0x0       0x0
Firewall 11/13/2005 2:16:12 PM  192.168.0.11     135       Exchange RPC
Server            Closed Connection         Inbound Exchange RPC
External            Internal  -           -                    There is
no initiated connection. Only closed. 
        7.      it is outlook 2003 sp2 on xp sp2 connecting to exchange
sp2 behind isa 2004 sp1 both on server 2003 sp1 

         

        Thank you for help. If anyone else got a suggestion I would
appreciate it
