Proxy Config

Question

Has anyone deployed guest access with proxy servers? I am looking to have a guest SSID cross proxy servers so cannot deploy proxy settings with group policy and need it to be automatic.
I have seen PAC, WPAD, DNS and DHCP may provide a solution but have not tested as yet. Any sugestions.

Answer 1

You can use WebAuth with a proxy, but you will need to:
1) Exclude the virtual address from the proxy
2) Configure the WLC to listen on the correct port (i.e. 8080 if you are using this). config network web-auth-port 8080
If using WPAD, you will need a pre-authentication ACL to allow the client to download the PAC file before passing web authentication. The PAC file should look similar to this:
function FindProxyForURL(url, host)
// variable strings to return
var proxy_yes = "PROXY :";
var proxy_no = "DIRECT";
if (shExpMatch(url, "http://*")) { return proxy_no; }
if (shExpMatch(url, "https://*")) { return proxy_no; }
// Proxy anything else
return proxy_yes;
Hope this helps.
