I took the /hub0002 off of the redirect, this changes the error to a 403
(12202).

Checking "Send the original host header..." still gives a 403/12202.

The link is http://webedi.bswa.com/hub0002 which WORKS FROM THE ISA
MACHINE, this is what I find confusing.

Try http://64.147.85.77/hub0002 to see what is supposed to show up. 

Then nslookup webedi.bswa.com to see that A=B.

How can I find out what request/headers ISA is really passing on to the
web server?

#3 is incorrect; ISA will not add path data to the original request.

Aside from that, the error you're getting is "WSAHOST_NOT_FOUND", a
Winsock name resolution error. This indicates that the host listed in
the "Redirect To" did not resolve to an IP.

Is there a public link we can hit?
I suspect that the pages hold something that isn't reachable from the
client...

Hi Jim

1. I have a perimeter machine (outside the firewall) which uses the
ISP's DNS.

2. at the ISA machine nslookup gets me the internal address of the web
server.

3. My web publishing rule redirects to www.domain.com/path
   Send original host header is NOT checked
   Ports are all left at default (80, 443, 21)

4. Yes, "hub002" was a typo.

Q1 - where are you testing this from?
Q2 - at the ISA server, what IP does "nslookup my-url" get you? Q3 -
exactly how is the "redirect to" defined in the web publishing rule? Q4
- this is a typo, correct? <snip> I am trying to map
http://my-url/hub002 to a local server http://192.168.2.228/hub0002
<snip> ..because if it's not, it won't work; ISA does not edit the path
data in web publishing rules.

1. don't use IPs in the destination sets fro web publishing.  It's bad.
2. only test publishing rules from outside ISA; at best, you'll get
inconsistent results testing them from behind ISA.

One more time (am I getting tired)

> I have a destination set defined for my-url/hub0002
> but http://my-external-ip/hub0002 gives me an ISA 11001

Should have read:

"I have a destination set defined for my-url/hub0002
but http://my-url/hub0002 gives me an ISA 11001"

(repost sans pgp sig)

Every time I think I know how to use ISA it sends me back to
kindergarten.

I am trying to map http://my-url/hub002
to a local server http://192.168.2.228/hub0002

I have a destination set defined for my-external-ip/hub0002
and http://my-external-ip/hub0002 works fine.

I have a destination set defined for my-url/hub0002
but http://my-external-ip/hub0002 gives me an ISA 11001

This isn't an issue on the internal server because I have "my-url"
mapped on internal DNS, and on THAT machine
http://my-external-ip/hub0002 works fine.

It's only when coming from outside the firewall, using the url, that it
fails. Yet nslookup on my-url reports our ISP's DNS entry is correct.

How do I isolate this? Any suggestions?

(PS: yes, I have rebooted. Often.)
