I was able to publish weboutlook to external clients. For some reason when I watch the log it shows denied request, but when I asked the users who are testing they said they were able to use no problem... weird..

now the oddest part is that I cannot access the webmail internally, only externally

so private.com resolves to my ISA server
isa has internal hosts file pointing to exchange server

when internal machines access private.com it hits the isa server, but then thats it
it doesn't want to do anymore...

Might sound silly, but do you have an OWA publishing rule set up, and in the properties where does "from" point to. Mine is set to anywhere, and users is set to all authenticated users.

Hi shankshank,

you should never loop back through the ISA server external interface. Therefore, either give the internal users direct access to the internal OWA site, or check out the following article serie

Hello

What do you mean by loopback?

I finally got it working
the config I used was
on my DNS server inserted new domain and added the internal host ip of ISA server
I do have the hosts file modified also on my ISA server

Ah. Now i'm running 2006
so I was curious that now I can use 1 cert for 2 listeners, then I should be all set?

I was also wondering do internal clients really need to go through ISA to access email? Or can I just update my internal DNS for to point to the exchange server directly, which won't have FBA but that is fine

Hi shankshank,

it's good practice that if the users don't need to have the same user experience when they are outside or inside the company, than the internal clients should not go through the ISA to access their email. Of course, a proper split DNS setup is required to accomplish that. Check out http://www.isaserver.org/tutorials/You_Need_to_Create_a_Split_DNS.html for more info.

HTH,

Thanks for the responses, greatly appreciated.
So I am bit confused. I have this split dns setup from reading other articles
but the confusion is, should internal resolve the actual internal server, such as mail server, or the internal interface on the ISA server?

See I don't use the ISA server for anything except exchange publishing, which means my internal clients then don't need to access the ISA server, do they

Hi shankshank,

if you don't matter about the same user experience than the internal DNS should resolve to the actual internal server. In that case, the internal clients will never touch the ISA server for that kind of traffic.
