Can you explain the steps to the firewall chaining method. I currently
have a back to back configuration but I am not sure firewall chaining.
We are experiencing problems with file downloads. I wonder if this is
why.

Yes, it can; I've done it myself.
How have you configured the Firewall chain; by name or IP?

I am about to configure a back-to-back ISA configuration.
As Tom Shinder writes i could chain the firewall services. But I
could not...Internal ISA seems to be unaware of the external ISA with an
eventlog that describes the unavailability of the other ISA.
I do not have deep konwledge about firewall chaning and I think
the problem is about the different roles of the ISA servers.
Shortly, internal ISA is in integrated mode and external ISA is
in firewall-mode. Do you know if firewall chaining can work with these
ISA servers?
Thanks for any comment,
Goktug
PS: Also I want to know why it is more secure using firewall
chaining instead of defining rules to a fix ip addres?
