Hi Chris,

I assume you also have a web publishing rule for the NFuse web site!

You have made the same mistake that everyone makes the first time they do
this with ISA. A Web Publishing rule is a reverse proxy, not a NAT.
Therefore, the NFuse web server will see the request coming from 10.10.10.5
(the ISA Internal NIC), and not from a 192.168.101.x address.

You will actually see this in the IIS logs from the NFuse Web Server.

So in the NFuse config, if you set 10.10.10.5 = Alternate it will work as
expected. You just can't use NFuse from the ISA Server itself. Who cares!

A Server Publishing rule, on the other hand is a NAT so the NFuse web server
will see the request coming from a 192.168.101.x address. But publishing
port 80 using a Server Publishing rule is not a good idea from a security
point of view.

I hope that helps explain what's going wrong.

We do this all the time, so ask more questions if you like.

Cheers,
Jeremy.

Subject: [THIN] Nfuse with alternate addresses

Hello,

Can someone help me with configuring my NFuse to user Alternate addresses.
I'm missing something I think.

Scenario :
Client (W2K)
ip adres 192.168.101.100
  |
  |
ISA Server
External Ip address 192.168.101.10
Internal ip address 10.10.10.5
Server Publishing rule that allows poort 1494 from 192.168.101.10 to
10.10.10.10
  |
  |
NFuse Server (WI)
IP Address 10.10.10.2
Configuration
    Default address translation setting  
      Normal address  
    Specific address translation settings  
       192.168.101.100 = Alternate 

Citrix Server (MFXP FR3/SP3)
IP Address 10.10.10.10
altaddr : Alternate TCP addresses for
          Local Address         Alternate Address
          --------------------  --------------------
          10.10.10.10           192.168.101.10

When I start the NFuse webpage I still get the local address in the ica file
instead of the Alternate address. 
Why ? How comes ? What do I miss here ?

Tnx for the feedback.
Kind regards,

Chris
