port 135

[Ritchie]

I am trying to hook up remote outlook 2003' I can do it within my loarger
network but once I tried to connect from outlide my router it would not
connect. I realized it had block port 135 on my router so I added a premit
tcp any host myexchange.server eq 135. I still can not connect outside of my
router.
permit tcp any "my exchange server" 0.0.0.0 eq 135
125 deny tcp any any range 135 139 log-input
125 deny udp any any range 135 netbios-ss log-input
Does any one know why this does not work ?

Connecting Outlook 2003 to an Exchange Server behind a firewall requires
MANY more open ports than just 135:

23. What ports does Exchange use?

You might want to consider either Outlook Web Access or RPC over HTTP

using the exchange RPC filter through ISA is the recommended access by
Microsoft and much simpler if I could just get it to work
