I get the point but ultimately you dont know if ISA is or isnt going to break
in Beta or even behave weirdly. regardless of ISA or Exchange or near
completion in the life cycle. My boss would tear me a new one if anything
happened and he knew that i was using Beta. Isa 2006 is beta software and hence
falls under the Beta "blanket" regardless of its "stance" in the security world
or record or reputation, Exchange and Bind would be the same, just because ye
olde version worked well doesn't mean the new one will and i'm not about to
find that out the hard way. I was always brought up not to do testing in a
production environment and from the reasons given and ones i have seen i do not
have enough persuasion to change my mind...
I think it all depends on whether you think that the steps you take increase
the chance of risk to YOUR network and for that matter your job. Also whether
the need for the beta software is great at that point in time, that is to say
what improvements, security or functionally or otherwise is a factor in the
overall decision. For me there has never been a need to rush at beta software
in my environments (home excluded) all our testing of new products is done in a
lab environment to ascertain the best way to attack upgrades and asses
functionality etc etc. So i guess we can differ on this and i suspect the
gallery will be divided on this one. might be a good topic for a poll on
isaserver.org and lucky prize for one of the voters, remember we used to do
those!!

We're talking about someone running it on their own LAN. Not sure where the
"board" or "business owner" stuff came in. I'm not suggesting that a
professional network/security specialist install beta software on customer's
production networks. I'm specifically talking about ISA 2006, as I stated
earlier. It's tight. I run it, I've tested it (and trust me, I'm made aware
of issues that MSFT sometimes never sees) and I have no problem with someone
who knows what they are doing running it on their own LAN. This isn't some
blanket statement about beta in general: I said, "Don't listen to Greg. Use
ISA2006 all you want (if you know what you are doing.)"
Comparing "full version public release" to "beta" has absolutely no meaning
whatsoever unless you know what has been changed between releases. I
participate in many different beta programs- and I've seen software go from
"beta" to "RC" to "RTM" without a single bit being changed.
If you know what you are doing, and know where the product is in the
development cycle, and are willing to be responsible for you own decisions in
regard to ISA 2006, then it is OK to deploy it. I do this, and am fine with
it. And I'm somewhat confident that I won't be looking for another job should
an issue arise.
We're professionals here. Let's not make blanket statements where they are not
applicable.

all:
From what I have seen of ISA2006 on my play LAN, it seems stable, works
well and to date, I have found no issues, and while I have not done full speed
tests, I have a gut feel that the performance is better.
However, It's got nothing to do with skill set, being comfortable or
anything like.
Purely on principle, I would not put any beta, or pre lease software
near a production LAN. This comes from 25 years supporting and developing
systems in corporate environments.
What about this situation;
There is some small bug / hole in ISA2006, that, as yet is it
undetected, it small, it's new and it's specific to ISA2006, it's obscure, but
it's there.
You put ISA2006 on a production LAN, and some one on the internet finds
it, finds the bug / hole, makes use of it, and hacks in and a customer list
find it's way onto the internet, or in the hands of a competitor.
There is an investigation, possibly with law enforcement called in, the
board finds out there was beta software on their production LAN, you're shot
your self in the foot, you are in an indefensible position.
Unlikely, yes.
Is there any bug / holes in ISA2006, my suspicion is probably not, but
the jury is still out deliberating on that one.
Would it be OK on a production LAN, probably yes, it will work, and
work without issues.
But, if an issue does occur, will any board or business owner support
using beta or pre release on their production system, not likely, more likely,
you're looking for another job. There also could very well be legal issues,
where you're exposed yourself to some liability claim.
It's just not a position you want to be in, no matter how sure you are
that every 'i' is dotted, and 't' crossed, you just don't want to be there in
the the unlikely event of an issue.
If it's full version public released software, the situation would be a
lot different, with beta, you done like a dinner.

People who know what they are doing. If you are not comfortable with
your skillset, then don't do it. But since you question our sanity, that means
that you just know something we don't. Please give us a list of your specific
issues with ISA2006 and the security vulnerabilities you have discovered.

Who in there right mind would use a product beta on a
production LAN ????
We have enough problems with the day to day stuff, and users,
and business needs , and.........
Why make extra problems of our own making !

Don't listen to Greg. Use ISA2006 all you want (if you know
what you are doing.)

1- install the ISA server after the adsl router and
before the switch.
2- put two interface cards in the server
3- attach one interface with the adsl router ( outside
) and the other to the unmanged switch ( inside )
4- assign an IP from your local lan to the inside
interface
5- assign any IP of the range that given from the ISP
( after the router nat ) to the ouside interface
6- make ur own rules on the ISA server

Greetings,
I have attached a basic LAN setup diagram and
I would like to pick your brains as far as the security is concerned.
My objective is that the In/Outbound traffic
must pass thru ISA box
Base on the attached design I feel that the
security is lacking. I have downloaded ISA 2006 BETA version...and I want to
introduce ISA Server as a member of the family to beef-up security.
How can I make ISA Server 2006 beta play with
this basic design, bearing in mind that I don't have a static IP address
from my ISP. My ADSL is dhcp obtaining the IP address from ISP.
I want to run ISA2006 on a separate box
completely.
With many thanks!
Gene Sibbs
