Hi Tom, 

No comments from Jim? That's strange...

Hi Stefaan,

Ha! I thought I was going crazy when I kept saying that SP2 broke Direct
Access. I'm glad you're seeing the same thing. I thought perhaps it was
something whack with my test bed.

Hey guys, 

There is a change in behavior if you configure sites for direct access (ISA
Internal Network properties -> Web Browser). It doesn't work the same as in
SP1! 

This is the configuration: a workstation with the Firewall client installed
and IE configured with the routing script. 

1. If you configure only the IP range for direct access:
   a) a request by FQDN in IE is sent as a Web Proxy client request.
   b) a request by IP in IE is sent as a Firewall client request. 

2. If you configure only the domain for direct access: 
   a) a request by FQDN in IE is sent as a Web Proxy client request.
   b) a request by IP in IE is sent as a Web Proxy client request. 

3. If you configure both the domain *and* the corresponding IP range for
direct access: 
   a) a request by FQDN in IE is sent as a Firewall client request.
   b) a request by IP in IE is sent as a Firewall client request. 


So, the question is obviously why is for case 2.a the request not sent as a
Firewall client request (this was the behavior in SP1)? 
Is this a bug and is there a workaround other than adding the corresponding
IP range?


Thanks,
Stefaan
