WPAD.DAT with IIS and DNS

Hi guys,

Hoping you can help, I am having some trouble setting up WPAD on a network I look after. They have only just got a wireless network so they now want to be able to use smartphones and the likes so this means that setting the proxy through GPO wont work.


The network is the following
Windows Server 2008 R2 Server
Windows XP Clients
Various Smartphones
Ruckus Wifi network using Zonedirector 1100 and Zoneflex 7363 APs


I have so far done the following-
Set up a WPAD website with IIS
Set up DNS so you can browse to the wpad.dat file by typing in

Quote:

---

wpad/wpad.dat

---

Create a wpad.dat file.

Quote:

---

function FineProxyForURL (url,host)
{
return "PROXY proxy1.equinoxsoltuions.com:80; DIRECT";
}

---

As you can tell from what i have posted they are part of LGFL and use the equinoxsolutions proxy. The problem i am having is that when i set a web browser to auto config it just hangs and nothing happens.

Any help you can give is greatly appreciated.

Cheers

Pat

should be wpad.yourdomain/wpad.dat iirc

Have you set DHCP option 252?
search google for wpad dhcp 252

When I browse to wpad.mydomain.local/wpad.dat I can also find the file.

I am not really wanting to use DHCP for it because I want it to work on smartphones and also other web browsers than IE.

Is my wpad.dat file correct? This is my 1st time setting this up so am insure weather I am even going in the right direction.

You had FineProxyForURL and not FindProxyForURL try

Code:

---

function FindProxyForURL (url,host)
 {
 return "PROXY proxy1.equinoxsoltuions.com:80; DIRECT";
 }

FYI, Ruckus 9.3 can support delivery of the wpad file directly from the ZD to the client at association level.

Is there a guide on how to do this anywhere? I couldnt find it on the Rukus site or in the documentation. Im fairly new to Ruckus so still learning my way around.

As long as you are running 9.3:

1) Configure
2) WLANs
2) Edit or Create new WLAN
3) Expand advanced options
4) Upload WPAD file or point to the server holding the WPAD file (useful for unauthorized clients needing the proxy)

So the file is then on the http://name or ip of zonedirector/uploaded/wpad.dat what do you then need to add to DNS and DHCP for it to automatically detect the settings bareing in mind that the wpad.dat isnt saved at teh root of the zonedirector?

Its is one or the other.

If you add the wpad to the ZD then the ZD delivers it to the client upon association. If you chose to deliver it via DNS or DHCP then you do not need to add anything into the ZD unless you want unauthenticated clients to obtain the WPAD file, which is useful for web-portal activation if a proxy is required for the ZD redirect

Umm it doesnt seem to be working for me on a test win7 laptop using ie9. The wpad.dat appears to be ok as if i check 'Use automatic configuration script' and point it at the address on the zonedirector everything works fine?

Is the WPAD working when taking the ZD out of the equation, i.e deliver it via dhcp or dns?

9.3 has only just been released so i am not aware of any bugs yet nor am i aware of anyone using this feature yet so feedback is nice.

Have you added the MIME type for the .dat extension in IIS? I don't think it is installed by default.

If it's not listed, add it as:

Extension: .dat
MIME type: application/x-ns-proxy-autoconfig

I'm going to test delivery via DNS i just need to remove wpad from the DNS block list which MS seems to have added in a 2003 security update. I'm positive there is nothing wrong with the wpad.dat though, i've tried 2 versions one is a renamed proxy.pac that works for clients elsewhere and one i created from fresh which is much more basic but works when you point to it under 'Use automatic configuration script'. Has anyone else got it working from the zonedirector yet?

I have done this, also unblocked the wpad setting in DNS
