Adtran routers will do this, too.  I’m in the midst of creating my “guest” 
wireless VLAN.  The nice thing about the HP M110 access points is that you can 
create two communities – on separate VLANs.  One for your users and one for 
your guests.

I have zero experience with Sonicwall, but being a Juniper user for years, this 
is something you can accomodate should you have a spare interface on your 
Juniper FW. You assign it a zone to it, if you like, or simply make in an 
"untrusted" port and route out to and from it, assign DHCP and policies.

Does the Sonicwall have the concept of “Zones” and can it act as a DHCP server 
with different scopes per interface?

 

Using a Juniper as an example, you configure an interface as a Zone (called, 
say, “Guest”) and assign it an interface and run a DHCP server on that 
interface.

So…I bought a wireless AP and it looks like I get to delve into learning a 
little VLANing.

 

Environment:

DNS,DHCP server (2003 SBS server, Domain controller)

Second DC (2003 R2 Server)
SonicWall Firewall
Dell PowerConnect 3448

17 Domain PC’s

HP M110 Wireless AP with non-domain PC’s using this to get to the Internet.

 

Desired result for WLAN clients: 

·         Able to get to the Internet, but not be able to see any domain 
systems.  

·         DNS configured to non-domain server (SonicWall would be OK)

 

I can VLAN with the PowerConnect and make it so that AP can only get to the 
firewall, but my issue then is how will any clients get assigned an IP address. 
I can configure the Sonicwall to hand out IP’s but then I lose control of IP’s 
(reservations, etc) from the SBS system.

 

It looks like I should divorce DHCP from the SBS server and put it on the 2nd 
DC and allow the AP to see the one DC and the Sonicwall.

 

Here’s a document I found helpful:
http://www.dell.com/downloads/global/products/pwcnt/en/howto_config_private_vlans.pdf

 

From that, the SBS server and all domain PC’s would be in Community 10

The AP would be in Community 11

The firewall and 2nd DC (now doing DHCP) would be promiscuous. Is that too big 
of a risk? The HP110 can do RADIUS and I did install that capability on the 2nd 
DC but I don’t really know what I’m doing here.

 

This would get me close to my desired result. Can RADIUS be used to 
conditionally hand out IP addresses? What would be nice is the ability to have 
it so VLAN1 (Community 10 in the diagram) gets some IP settings, VLAN2 
(Community 11) gets others – namely a different DNS server.

 

All thoughts and comments welcome.
