I have an ISA Server 2004 Standard with SP2 and a domain environment. I can't get webmail, sharepoint, or ftp sites that are internally hosted to be available externally. I have setup the rules correctly (I am pretty sure). Is this a common problem that only takes a few seconds to fix?
Now, this could be several issues. 1) I don't know how to set up these servers in the DNS. Do I need to create aliases or make any special host records or anything like that? Do I need to have them in the ISA DNS too? or not? And would there be a conflict if our internal network is the same thing as our web page URL which is externall hosted? So say our web page is xyz.com from another company, and our domain name is also xyz.com. Is there a problem there?
Thanks guys. This will clear most of my issues! Sean
Sure (thanks for the reply) My example rule is called "SharePoint"
Allow HTTP Protocol From Anywhere Using Listener (Listening on external network with a selected IP, no SSL required (yet), integrated authentication, all users required to authenticate) To servername (requests appear from original client, original host headers not sent) Public Name - www.mydomainname.com/servername (was created by default, i didn't change this)(is this the address I use to access this?) Path - /* All Users
I'm getting 403 Server Denied the connection when requesting by http://servername.domainname.com I get 404 when using http://www.domainname.com/servername
Haha, we are closer than you think! Turns out, ISA was not the issue. I had the rules created beautifully.
I fixed the issue with some luck and expirimentation. First with sharepoint, there's an option to give it an External URL. Which I gave "portal.domainname.com" Then I had to create an Alias in ISA's DNS to match "portal" to the web server name. And the server name had to have a host record matching it to the Internal IP (which is all I had and couldn't figure out why it didn't work)
Back to the rule: So now, my "To" name is "portal.domainname.com" and the public name is also "portal.domainname.com"
Now, i've recreated the rule and went with all the default authentication. I am pretty sure i'll want to use SSL on our sharepoint site. But getting something externally available has been a huge hurdle for me and the previous admin.
So where would I get the information about the DNS stuff necessary? Or should it have been a no-brainer?
