No mention of HTTPS. Just TCP 57017. The parameters, as in the
properties of the policy? As simple as can be:

Order = 1
Action = Allow
Protocols = TCP 57017
From = Local Host
To = External (for testing purposes, otherwise would be destination
Internet IP) 
Users = All Users (default)
Schedule = Any tiiime (default)
Content Types = default

Add an https tunnel for that port and try it.......

Thanks, Amy. I have created an all outbound rule to the destination IP
address and only see the connections to TCP 57017 denied by the last
rule (SBS Internet Access). Unfortunately I am being challenged by:

* The software developer insists the software must run on the server;
which happens to be SBS 2003 Prem. 
* The software developer (at this point) will not go beyond stating that
TCP 57017 is the only necessary network traffic to be permitted
* The software is key this business and there really aren't many
alternatives 
* The software runs on the SBS server which is also the ISA server
(which should still be possible to figure out)
* ISA monitoring is not providing me anymore detail other than the
denied TCP 57017 connection; although I will run another test 
* The software does not have any network settings or pseudo /
non-compatible CERN Web proxy settings
* The all Outbound rule you suggested did not work; although I will run
another test
* The software worked before the ISA firewall was installed because they
simply had NAT router without true firewall functionality 

Cheers,

Danny,

 

The order of your policies is not being ignored. Isa will read them top
down. Since you're hitting the SBS Internet Access rule this means that
the traffic does not apply to the rule that you have created. When
that's the case, ISA moves on down checks the next rule. Finally it
reaches the SBS Internet Access Rule and since there's no authentication
it is denied. 

 

So, as I said before, the rule isn't configured correctly. You need to
find out what that apps wants and the configure your rule accordingly or
take my suggestion and set up a rule allowing all outbound to that
specific IP address.

 

Amy

Jim, 

I appreciate your educational tidbits, but when you are dealing with
humans and software sometimes assumptions are inevitable. In fact, it is
clear that you are not immune to making assumptions.

1) By stating the obvious that "Assumptions get you nowhere", you assume
that assuming is my favorite activity and always gets me positive
results 
2) By providing a WSUS and AU 101, you assume that I did not understand
the difference between a WSUS client and an Internet-based Automatic
Update client, did not read the KB's, was not the one who installed
WSUS, and have no clue 
3) By challenging my knowledge of who Amy is, you assume that I had no
idea who Amy is and didn't care. First of all, where did I not show
respect to Amy? Secondly, do you want all ISA list posts to begin with
"Yes, I know who Amy is, so um don't ask me"? 

Anyway, yes, I did bring up some Microsoft pain points and I will
respond to any further responses offline. As you know this list has been
very flexible with OT posts, so my addition is nothing to call home
about. 

Re: cutting off the thread, I would say 70% of the reply content is
redundant and has no value in the conversation. The archives should be
stored by threaded conversation, but I will respond in the format you
request. 

I will analyze the ISAINFO output, but for future reference, can you
please direct me to documentation that will explain why the order of
polices is being ignored OR why I would not see all denied traffic in
the ISA 2004 SP2 monitoring default state (Log record type = Firewall or
Web Proxy & Log time = LiveConnection Status = live)? 

Thanks,

...D

        Assumptions get you nowhere.
        You brought up the plethora of pain-points - expect someone to
answer 
        them.
        WSUS and the Internet-based updates process works very
differently,
        because the WSUS server determines for the client what is
required and
        what is not.  Amy has a clue (several, actually); this is a rare

        commodity in the SBS community and you should feel free to take
        advantage of it when it appears.
        
        Also, please stop cutting off the thread.  It makes archive
searches
        very nearly meaningless.
        
        Regarding the "custom app", the log snips you provide clearly
indicate 
        that your rule is not being applied, since the denying rule is
quoted as
        "SBS Internet Access Rule".
        The best way to express your ISA policies is to use ISAInfo.
        You can respond offline if you like.

                Your rule must not be configured correctly. What does
your
        custom rule look like? The only reason that the SBS Internet
Access Rule 
        would deny anything outbound is if the app isn't authenticating.
It's
        not uncommon. My bet is that the app doesn't only require that
specific
        TCP high port but a range of them. I'd base the rule on the IP
address 
        it's trying to reach instead.
        
        
        The policy is: Custom Protcol TCP 57017 Outbound, from Local
Host, to
        External, All Users.
        
        
        Warning the following section is OT:
        
        
                Yes, the SVCHOST issue is a nuisance. The screeching is
loud on 
        the mailing lists. It took me a while to figure out what
everyone was
        complaining about then I realized that I use WSUS everywhere.
Implement
        WSUS you'll be much happier.
        
        You imply that WSUS clients are immune to this? Most of our
affected 
        systems are part of WSUS installs. My understanding is the
Automatic
        Update service (aka part of svchost.exe) scans the same way a
non-WSUS
        client does, therefore they are both affected.
        
        
        Sorry for bringing this OT item into the conversation, but the
last two 
        months in particular have been difficult to support Microsoft
        environments when dealing with DNS RPC mgmt vulnerability, ISA
2004 SP3
        install woes, a publicly unavailable (two hours MS PSS phone
call) KB
        for restoring the ability to publish Outlook forms to the
Organizational 
        Forms Library in Exchange, and this AU/svchost issue - but looks
like
        there is a follow-up:

        w-up.aspx
        
        Anyway, can we focus on what I am doing wrong with this ISA
issue, that
        would be much appreciated.
