Hi Jeff,

Sonicwall can't provide secure Exchange RPC access for your remote
Outlook clients. For a secure setup, you need to forward all traffic to
the ISA firewall and allow ISA to do the firewalling. Sonicwall is just
a tradition packet filtering NAT router and can't provide the layer 7
intelligence required to secure the Outlook/Exchange RPC transactions
properly. 

HTH,
Tom

I have been testing ISA server. Do you have to open any other ports?
Also I am behind a sonicwall firewall so I will nat or forward ports to
ISA server wan interface. But is there any other points for
configuration I should consider.
I saw the wizard that connects the ISA server to exchange is there any
other
ISA server configuration. 

Thanks Jeff

Hi Jeff,

I've enabled ISA Server secure Exchange RPC publishing for several city
and county govts, and it works a treat. The only issue it getting the
ISPs to open TCP 135, but that's getting to get less of a problem now
that the worm hysteria is settling down.

HTH,
Tom

        I have users that connect to exchange remotely through VPN. I
have tried using OST files but notice when exchange synchronizes the OST
file it Takes too long, not fast enough for slow connections. I noticed
there are some settings in 2002 outlook client For send and receive
groups that may be useful. Was wondering if some has a system for remote
access that works great with large email accounts. I know about OWA ,
but my clients prefer using there normal outlook interface. Is there a
way to connect to exchange remotely with out synchronizing and collect
only new email. I am using IMAP now but was hoping for a solution for
outlook exchange client. Also any suggestions On minimum bandwidth
requirements to implement successful remote VPN exchange access.


Thanks for any help
Jeff
