But there is a defined route on the Isa firewall. The server know
exactly which one is the route to solve the requested address.

 

I guess the problem is the ISA firewall for some reason is not giving IE
the right exclusion list, so IE no matter what will try to use the
firewall. Because if I leave the same proxy configured on IE but
manually add the exclusion it works.

But I have no idea how to fix this issue or where to search for the
error on the configuration.

If the Firewall client machine sends to a destination that is not part
of the defintion of the ISA Firewall Network on which the client is
located, the Firewall client will remote the connection to the ISA
Firewall to send to another ISA Firewall Network (such as the default
External Network if there is no defined route on the ISA Firewall for
the destination Network).

        What is the "ISA client"

         

        There is a FIREWALL client, SecureNAT (SecureNET) client, and a
Web proxy client.

         

        THERE IS NO "ISA CLIENT".

         

        HTH,

        Tom

                Good morning everybody (well, for most of you ;-) )

                 

                I have the following scenario:

                 

                Subnet 10.200.*.*(NY) and subnet 193.138.73.* (Geneva)
both are internals and connected with a router no ISA in the middle.

                For the NY users the Internet proxy (ISA 2004 array) is
on the 10.200.*.* subnet and they have the ISA 2004 client installed
configuring IE automatically.

                 

                The NY guys are trying to access a citrix server in
Geneva with IE, the Geneva range was included on the NY proxy array as
part of the internal network, also on the Web Browse TAB (internal
network properties) so the proxy is bypassed when accessing that subnet
and the subnet was also included on the routing table of both servers
members of the array.

                 

                The point is citrix failed to open a desktop session.
They can reach the login page and even login, but session failed to
open.

                 

                Now, if I disable the ISA client and manually add on IE
the Geneva subnet between the exclusions, everything works fine.

                 

                Any idea of what can be happening?

                 

                Regards
