  • 2. ISA returns html code instead of website
    Hello, we use ISA 2004 with SP1. I have published a webserver with a webserverpublishing rule. This works fine. But sometime the ISA server sent this back POST /index.php?id=16 HTTP/1.1 HTTP/1.1 200 OK Connection: Keep-Alive Date: Wed, 09 Nov 2005 08:03:08 GMT Content-Type: text/html;charset=iso-8859-1 Server: Apache/2.0.54 (Debian GNU/Linux) X-Powered-By: PHP/4.3.10-16 Keep-Alive: timeout=30, max=100 Content-Length: 24971 that message is followed by the html code from the website. I can reproduce this problem only with firefox, but other users say that they have the same problem with IE6. Thx Kai
  • 3. ISA 2000 Restore Options to get at only Site and Content Rules from a .bif
    Ok, I munged up my ISA 2000 Site and Content rules (deleted them.. don't ask).. unfortunately the only backup I have is a year old, so I do not want to restore from that .bif. Is there anyway I can just get to the Site and Content Rules of that backup, so I can recreate them by hand ? Without creating a restore server ? Thanks for any ideas you have.. Sigh. Bob
  • 4. How to edit the filter information on the log viewer??
    Hi, I really need your help. I'm new at ISA Server 2004 and I want to create some rules to filter web information in the log viewer; I have searched a million sites and nothing comes up. I need to know what web sites had the users of my internal network visited in the past 30 days, without images, without repeated IPs or URLs, number of requests and transfer bytes. Does ISA allows to do that?? I'll appreciate your responses and examples. Thanks in advanced. Best regards, Bets.
  • 5. Configure proxy server - no authentication
    Hi, currently my isa server requeires authention, set on outgoing web requests using Integrated. for some testing I want to turn off the need to authenticate. If I uncheck the integrated checkbox in the outgoing web requests I got error 502 then trying to access an http address. How am I supposed to bypass the need for authentication? thanks /Niklas

Route to multiple SMTP Servers

Postby Alfredo Ardito » Thu, 20 May 2004 15:40:54 GMT

Hello all,

I might as well tell you i'm a newbie, therefore I might ask dumb things.

I would like to know if ISA server can handle 2 mail servers in order to
have mails from certain domains forwarded to mail Server A and mails instead
from other domains routed to mail Server B.

I would like to setup an ISA standalone server and 2 mail servers behind it.
The 2 mail servers would have, for example, Merak mail installed on Server A
and MailEnable installed on Server B.

With this kind of configuration, I would like mails from routed
to Server A and mails from routed to Server B.

Is this possible with ISA server? If not will ISA 2K4 manage to handle this
kind of configuration?

Kind regards

The first option would be to have to IPs on you ISA server and create 2
publishing rules.

of course the MX of domA use IP1 and MX of dom B use IP2.

Another option is to use the Microsoft SMTP Service on the ISA itself and
create SMTP routing rules. In this case ISA does not route anything but the
SMTP does, ... and it should work fine too.

Hope this helps.

1.Multiple Internal Networks - ISA Server detected routes...

Hi folks,
Need some help please with the "ISA Server detected routes through adapter" 

On a new implementation of a 2 node ISA 2006 array I have multiple internal 
networks: - Network1 - Network2 - Network3 - DMZ - Intra-array - Internet

I created the network definitions using only the to as I 
cannot put the in multiple networks which adding the adapter 
would do...
..but thats where my problem is I believe, in thats what ISA wants??

What have I done wrong, or is this a fundamental design problem?

Can the errors be ignored as it all appears to work, or should I change the 
configuration, or should I use 172 networks rather than 10 networks (so I can 
use 172.x.255.255 in the network definitions) ??

2.How to configure ISA 2004 to route POP3/SMTP traffic from Outlook Express to mail servers

Dear all,

we have setup ISA 2004 sp2 as a Web Proxy (Single adaptar). It is
listening on port 8080. We are able to use this as a web proxy for
browsing internet using Internet Explorer. we have also opened all the
required ports from internal to external.
when i enable logging from monitoring window. I can see only web
traffic and no POP3/SMTP traffic. On further investigation on the
client i could see after resolving the site the client was trying to
connect directly to the mail server for accessing the mails. where as
it should have used proxy for the same. Outlook Express doesnt detect
proxy settings and go through ISA 2004 proxy server.
Please help

3.Difference between SMTP Server and SMTP in ISA Server 2004


What is the difference between "SMTP Server" and "SMTP"
protocols in ISA Server 2004?  I notice in the firewall log that
most of the spam mail come in on "SMTP" protocol.

Can I block SMTP protocol from the outside?  I think I can
only expect server-to-server SMTP connection, right?

Thanks in advance. 

4.Multiple Networks, One ISA Server, Multiple Proxies?

We have two (and if we can make it work, eventually three) networks
behind an ISA 2004 server.  We are using a PacketShaper to help curb
the flow of internet traffic across all of our subnets in an attempt to
give certain trusted networks a bigger piece of the bandwidth pie.  The
way we were doing this was by source IP.

Traffic from network A comes through as 10.10.X.X, and traffic from
network B as 10.20.X.X.  Our ISA device sits in the middle, forwarding
traffic along as  The problem we're having is that all
traffic EXCEPT port 80 web requests are being routed like we want - the
PacketShaper sees them as 10.10 or 10.20.  For port 80 web requests,
the PacketShaper sees the address of the ISA server, since
the server is proxying the request on behalf of the client, no matter
which subnet it's in.

Ideally, we would continue to *route* traffic not proxy it, so a web
request from port 10.10 would hit the PacketShaper as a web request
from 10.10, and would be cached on the way back.  If that's not
possible, then it's fine if we configure the ISA to forward web
requests on two different IP addresses ( and .20, for
instance), but so far I can not find any way to make this happen.

Any suggestions would be greatly appreciated!

5.Allow inbound SMTP to local SMTP server

I've just upgraded from ISA 2000 enterprise to ISA 2004 enterprise on a 
W2003 server.

I run the W2003 SMTP service locally on this server to relay mail in and out 
from an Exchange server to the Internet.

I can't seem to be able to create a rule that will allow SMTP inbound to the 
local SMTP server.

Any tips?
