Hi all
i have setup ISA 2004 and all runs fine and when i setup exchange en publish owa (used the tutorial of Tom for publishing OWA )it works great too, but i do not know how to redirect from
webmail.mydomain.com/exchange to webmail.mydomain.com ( when i type this, it must redirect to webmail.mydomain.com/exchange )

another problem is that when i want to publish multiple websites with host header, it doesnt work at all. all urls goes to the default page or i got an 403 error acces denied.

isa runs on windows 2003 (apart)
exchange runs on windows 2003 ad

i have read some isa 2000 stuff but i cannot used it with isa 2004, because 2004 is quite different
hope u guys can help me out

Hi Hung,

I haven't tested host headers because they don't work with SSL.

Not sure what you want with the URL.

Do you want this:

User enters:
http://mail.domain.com

and have it redirected to:
http://mail.domain.com/exchange?

I think the problem is that if you do this, the entire site would need to be a subfolder of the /exchange directory, which would not work.

It would be better just to publish mail.domain.com/default.htm and include on that page a meta tag for a redirect.

HTH,
Tom

Hi Tom
I did redirect my url with a meta tag and it works well, but can this not be done with isa 2004 with a rule or something?

and i only want to use OWA with ssl and the rest websites through port 80
but all goes to the default page, can you explain to me how to do this?
thanks for your reply. I did not expect a reply from u so soon, guess i am lucky [Smile]

Hi Hung,

The problem is that you can redirect everything that goes to http://mail.domain.com/ to http://mail.domain.com/exchange, but what happens is when a user then needs to go to http://mail.domain.com/public, the request gets redirected to http://mail.domain.com/exchange, which won't work. That's why the meta tag, or some .asp script, is the better solution.

HTH,
Tom

Hello

I am currently publishing Exchange 2003 OWA through a unihomed ISA server that resides on the DMZ segment of a PIX firewall. I would like to have it setup so that when a user types mail.mydomain.com into their browser they get redirected to https://mail.mydomain.com/exchange. I have been able to achieve this by changing the default web site to contain a .htm document that redirects to /exchange and I made this document the highest on the list of documents for the default web site. I then published the default web site through ISA. Now when I type in mail.mydomain.com I am redirected to the Exchange Virtual Directory and prompted to login. I have not experienced any issues with not being able to get to other directories like /public. But I am concerned that I may have bypassed the security I gained by using ISA. My main concern is that I do not want to weaken security, but I feel that I may have by publishin the default site.

Thank you-

Hi Voltech,

You can use the ISA 2004 redirect feature to redirect connections to the root directory to a folder in the path, so that the connection never even makes it to the Web server and is redirected by the firewall.

That will avoid the security issue with publishing the root directory.

HTH,
Tom

But can ISA redirect from http:// to https:// ? I have only found the setting under properties of the firewall policy -> action tab -> deny, checkbox only allows http://something, not https://something.

Am I in the wrong spot?

Thanks,
Joe

Hi Joe,

Why would you want to do that? It implies that you trust the open Internet more than the network behind the ISA firewall.

Thanks!
Tom

Tom,
I have been using the beta version of ISA 2004 and had published the default website on my exchange server with a .htm file that redirected users to webmail.company.com/exchange. I have recently updated the beta to rc1 and this rule no longer functions the same. now when users go to webmail.company.com they are redirected but when owa loads up the two frames come back with internal server errors. any ideas?

If you want to use a redirect page the only path in the firewall policy will be /* correct?

Thanks for the help.

Hi Tom,

Sounds like FBA is enabled on the Exchange site. Double check on that. I definitely have not run into this problem with RC or RTM.

You might try dumping the cache and configuring a cache rule that prevents caching of the Exchange site.

HTH,
Tom

Hey Hung77,

sorry for the late reaction. Use this webpublishing rule for webmail.domain.com

<same as internal> /Exchange/*
<same as internal> /Exchweb/*
<same as internal> /Public/*
/ /Exchange\

Mind you , the last one after Exchange\ is a BACKslash , to fool the ISA server a little ( works in ISA 2004 final also ).

This works for us and it hasn't given us problems for 3 months. ( 4000 users so it's been tested thouroughly )
You need to change some rights on the language files in the public folder , but I can't remember which ones , you will find out soon enough.
If you want I could look it up in the documentation for you but we're quite busy atm.

Kind regards,
Lex P.

Hi Lex,

Just so that I'm clear on this, in your Exchange OWA publishing rule, you include the following paths:

/exchange/*
/exchweb/*
/public/*
//Exchange\

Is that right? Very interesting, as I don't see how that would redirect a request from:

owa.msfirewall.com/

to

owa.msfirewall.com/exchange/

Thanks!
Tom

Hi Tom ,

No I'm sorry the spaces were wrong.
You need to publish this instead :

External Path Internal Path
<same as internal> /exchange/*
<same as internal> /exchweb/*
<same as internal> /public/*
/ /Exchange\

To do this re-direct, on the IIS website in question, go into the properties of the root folder and select homepage. Change to "A re-direction to a URL" and put the redirect to as /exchange

Then check, a directory beloe url entered.

This will direct any oma.mydomain.com to oma.mydomain.com/exchange

so can i clarify:

in IIS, i amend the "home directory" properties of the default web site with the /exchange and "directory below" check box?

when i try this, i get prompted for a certficate (as per normal) and upon accepting the certificate, i get error code 403 instead of a username/password prompt....

Hi all,

I just wanted to add that we've created a filter called WebDirect that can (among other things) handle the http to https redirection at the ISA server boundary. This way your users don't have to know to type "https" when trying to reach the mail server. Version 1.1 will also have the ability to do path remapping, which would take care of some of the other issues brought up in this thread about automatically funneling incoming connections to the "/exchange" directory, etc.

Sorry for the blatant plug [Wink]

but it seemed on-topic here. Anyone interested, check out http://collectivesoftware.com

Thanks!

Mark,

I know that "/exchange" in the Default Web Site works for a normal "FE/BE" setup, but I haven't had success getting this to work with ISA.

Are you using ISA to "proxy" OWA?

Tom: do you have a best practices solution to this problem? If you do, could you please add it to your "how to" on setting up ISA as an OWA Proxy? (http://www.isaserver.org/articles/2004pixwebproxy.html)

Thanks!
