Hi all,
I have a problem, pls instruct me how to config ISA server for my case.

This is my network diagram
http://heartit.esmartweb.com/isaconfig.gif

I have read document about ISA server, and tried on configuring Publishing server (POP3+SMTP) for Host A can use Outlook Express check mail from both local network and internet. I implied 10.10.11.x/24 is external network and 192.168.100.x/24 is internal network.
But I failed, because external IP, in my local network, is an private IP.
Moreover, my server mail is Qmail in Linux, instead of MS Exchange Mail Server

Thanks for your help.

Hi quangminh9999,

You need to create a split DNS to support transparent access for internal and external hosts.

HTH,
Tom

Hi tshinder
Thanks your reply
I'm sorry, I have still not understood your guide in the case yet.Pls help me one more, more detail more better if u can do and have free-time

I infer from your idea which you have just helped me. My inference is suitable your idea ???
Step 1:
I need to have to setup a local DNS server and create domains for my local mail-servers ???
Local DNS server is on ISA server, it also supports to forward to Internet-DNS ???

Step 2:
In NIC 192.168.100.1, config DNS is the local DNS which has just setup ???

Step 3:
In NIC of HostA, config DNS is the local DNS which is on ISA Server ???
In Outlook, config account mail with POP3/SMTP by domains of local mail-servers created in step 1

-----
Pls, help me understand more your idea

Hi all
I inferred from tshinder's idea. And I configured by that inference, but I failed.

Would you please to help me ?

In wingate, we can map a pair of IPs between network 192.168.100.x and network 10.10.11.x.
I wonder,why people said ISA is stronger than wingate but ISA does not have a way to solve my problem.
Maybe, ISA is weaker than wingate, at least in my case

Because I want to try on using ISA, I also try my best to how to configure ISA with my network. But I can not do myself. So, I have had you help me. And maybe nobody can help me

Thanks all
