OK.  It's clear like that.

Indeed, if this is only for some kind of Cosmetic test, just install them an old machine, a browser, a phone line and 
some free internet access...  THis should reduce cost...
But anyway, This machine should be secured well, patched abd anti-virus up2date installed..  The net is so Wild today 
;-)
Concernning VNC...  I'm not sure I would leave a machine on the net, with a VNC server waiting.  Or at least I would 
secure it, Using SSH (IIRC this topic has been discussed more in depht on the list, a few weeks ago) and some very 
STRON password.

Regards,

Max

What I meant was that sometimes your not testing speed, but how things look and accessibility to the outside. So you 
need a machine outside your own network to come in from outside. So any machine outside your net would work. Why not 
use a home computer. Good as any. Use VNC to take it over, then have the home machine access your company system from 
outside. (This would not be used for speed testing.)

This way you could see if outsiders are getting the correct access privileges, java / perl / cgi codes, ect.....

Basically a poor mans outside setup. Hell you could just stick a box on a dialup account in the corner. Just don't 
connect to your network. (I have an old laptop for this as well as programming voicemail and router.)

I'm not sure I fully understand your VNC proposal...

But anyway, using an other line to test the application is a good idea to test in a real live case.

I'm not sure exactly what "user experience" you are trying to test. To me, saying they want a DSL means they are not 
interested in speed testing. Otherwise they would test dialup, as most users still have this. One way to quite down the 
request is to see if the programmers have DSL or cable at home, have them use VNC or PCanywhere and test from their own 
home machine
;)  

There is a benefit to such a setup. Currently I have Partial T1, DSL, and cable here. All different providers, and only 
one of these hooked directly to our internal net. It does help to check from outside the company how users are seeing 
the data. 

It is also pretty funny to do a traceroute on 2 machines sitting side by side, and it takes 17+ hops :)

One thing which no one has mentioned yet is a variant of this.

Instead of making a connection to the LAN, get the developers removable media.  2G ORB drives are reasonably affordable 
and let you move a big chunk of data back and forth.  They can use their development machines to set up what they want 
to test on the removable disk, then stick it in the other machine for testing.

Make sure all machines involved have good virus protection.  Perhaps different versions for the internal LAN and the 
Internet visible one.

Hi,

You could create a little separate LAN for them  :

DSL Router --- Firewall (Linux based, on a recup PC) --- TEST LAN

If the goal is to test the end-user experience, they will probably ask 
for different OS..  So Why not think about making a little private LAN 
with Linux, Windows,(Dual Boot/VMWare??).  Just imagine..  I had this 
kind of requirement for a Web developping Company, and this is what
we did.  We knew that the developpers were  not specially 
Security-Minded, and the Boss was paranoid...

At a first stage, there was NO connection at all with the production 
LAN, which is the safest solution ..  But as they needed to exchange 
some file , we connected both LAN via a Firewall, allowing ONLY FTP 
traffic from Production LAN to Test LAN, using a FTP proxy and a Virus 
Checking (Trend Micro Viruswall..)=
So DEV team can work as usual on the Prod LAN,.  want they to 
test their finding?  Just moving to an other keyboard... 
without jeopardysing the prod LAN Security... 

Hope this help..
Should you need more details about the config, just drop me a mail Off 
list @ info () emmera be

Regards,


MAx

Security Pro's:

      A group of my programmers want to have a DSL connection
put in their testing area so they can simulate end user
experience across the Internet. I have concerns with this and 
am curious if anyone else has found a good solution to 
provision their business requirement without putting the 
network at risk.

      I know I haven't gone in to enough detail for an EXACT solution but 
in general if anyone has any "tips" I'd appreciate it. Thanks!
