Re: Problem with ISA, I think ...

You couldn't extend a single cable to each of the out buildings and then
simply setup WAPs inside the building? You don't indicated how big those
out buildings are and how many folks are working in each.

You say you have WAPs at each build with directional antennas...what are
those directional antennae for? Client access or sending signal to main
building? What do you have receiving at main building.

If you can't run wire between the buildings...not sure the standard DLink
stuff will do the trick for you

Well, I contracted with a VAR I trust to design a wireless network, and a
3rd NIC was in his plans. Here's what I sent him back in early March:
"
Problem: Our 'complex' consists of 4 buildings. Only the Administration
building is wired (CAT5) for the LAN. I am using D-Link products to extend
the LAN to the other 3 buildings; the furthest is about 450-ft. from the
omni-directional antenna on the Administration building. I have WAP's on
the 3 out-buildings connected to directional antennas (30-deg angle
up-down, left-right). The signal strength within the buildings only ranges
from poor-to-fair. I had expected good-to-excellent. We also have a
problem with visitors with their own PC's, Mac's or laptop's. I don't know
how to give them access to the internet without (possibly) compromising
the security of our LAN.

Requirements: (1) Provide a reliable signal to all parts of each building.
(2) Find a means to provide internet access to visitors much as you'd find
in a public library, university, or airport. (3) Provide a means for
wireless access to the LAN (on my end I'd join the computer to the domain
and add the visitor as a domain user). (4) Integrate the existing
equipment into the solution as much as possible to hold costs down.

Existing Equipment:

Router: Amer.com Model # BR-4; 5-port

WAP's: D-Link Model# DWL-2200AP, Qty: 4, capable of wireless 108g MIMO

Antenna's: D-Link
Model#'s ANT 24-1400 "



And his solution:
" I have looked into your wireless problems and I have come up with a
solution using your existing equipment. Also, the current Access Points
that your using do support VLANs so you can separate network traffic from
Guest traffic. To do this, you will need a Layer 3 switch that supports
VLANs. I would recommend sticking with the D-Link products to keep things
the same. A D-Link switch that will do this is D-Link Part #: DES-3828.
An additional Network card in the server will also be required for the
Guest VLAN, and ISA 2004 needs to be installed on the Server, which I
believe it is. You can then use ISA to control the security on the
traffic.

I have listed the additional wireless equipment that you will need to
accomplish getting signal in the Build that you sent a drawing of. The
Antenna Guide at D-Link shows that the antenna below will work with the
access point below.
http://www.dlink.com/products/antenna-compatibility-chart.asp Basically
you need another Access Point (Same model as the ones you are currently
using) and an indoor antenna.

- One AirPremier 802.11g Access Point with PoE : D-Link Part Number
DWL-2200AP
- One Indoor 4 dBi Omni-Directional Ceiling Antenna : D-Link Part Number
ANT24-0401

You will have to get the new Access Point connected to the one that is
connected to your directional antenna. You can do this by plugging both
devices into a small network switch in each building."

I haven't even started with the VLAN as I just installed the switch. My
plan is to get the LAN up smoothly and then transition to VLAN's.

Any thoughts/comments?

Mike

SBS just doesn't support 3rd nic scenarios.
Wizards can't accomodate it

Why not just setup a wireless access point connected to the switch for
your wireless network?

Running SBS 2003 Premium, ISA 2004, Exchange, SQL, WSUS, 3 NIC's and a
router, dynamic IP, DDNS service through dyndns.org, Symantec Backup
Exec 11d.
=========================
Just installed a 3rd NIC to do VLAN's on my wireless network, and also
installed a D-Link managed switch - DES-3828. All I've done with it is
give it an IP address and set the subnet mask, DNS and WINS. My network
is set up as follows:
External NIC - 192.168.1.10
Router - 192.168.1.1
Internal NIC - 192.168.16.2
VLAN NIC - 172.16.0.1

Switch - 192.168.16.150, 255.255.255.0, 192.168.16.2 for DNS and WINS

My problem is this: I can't access the web management page on the server
from IE7 or Firefox without unticking the proxy server boxes in Internet
Options > Connections > Advanced. Event then, parts of the page aren't
displayed right - I see small red x's as placeholders on the menu, for
example. I can access it from another computer using IE7 - as long as I
untick the proxy server boxes, however, I cannot get to it from Firefox,
even after I untick the boxes. Do I have to do anything on ISA, or is
it something else?

On a related note, I can ping sites from the command line just fine.
Can only get to sites from a browser if I untick the use of the proxy
server.
