Cisco WLC and Unsecured WLAN with redirect

Hi Folks,

Can someone point me in the right direction heer.

I have a WLS box - i want to create a WLAN which will

          1.)     allow anyone to connect to without authentication.

          2.)     once connected they need to be redirected to a web server for further instructions.

Any suggestions greatly appreciated.

Cheers

Re: Cisco WLC and Unsecured WLAN with redirect

Hi Rob,

You need to create web-auth security with passthrough.

here is a guide:

You choose "passthrough" rather than "Authentication" under L3 security configuration of the WLAN.

configuring the redirect page is under Security-> webauth -> webauth login page. (described in the example above.

Cisco WLC and Unsecured WLAN with redirect

Hi Amjad,

Thanks for that. I followed the directions and my clients can connect and are redirected to the desired page.

The only problem is that before they are they are redirected to a https Accept page which states "Cisco is pleased to provide the wireless LAN infrastructure for your network. Please login and put your unified wireless solution to work"

Once i click "Accept", it redirects me to the page i want.

Any idea how to get around this.

Cheers

Re: Cisco WLC and Unsecured WLAN with redirect

You can configure the splash page to say the customers name instead of Cisco.

To add to this conversation for clarity.

You can either use the supported default welcome page also called the acceptable use policy.

Or, you can add your own custom screen. If you go to cisco's wireless controller code download section you will see a webauth bundle.

Contained in that bundle are about 1 dozen web page examples. From which, you can modify to your liking and upload to the controller.

I hope this helps ..

Re: Cisco WLC and Unsecured WLAN with redirect

Hi George,

This sounds like what i need.

I will investigate and report back.

Cheers

Re: Cisco WLC and Unsecured WLAN with redirect

Excellent .. Stop back if you have any problems. So you know, TAC DOESN'T SUPPORT HTML pages. So if you run into HTML problems Tacs response is "you are on your own".

But I think you will find the examples easy to modify.

Please support the rating systems if any of these responses by the members were helpful !

Thanks !

Re: Cisco WLC and Unsecured WLAN with redirect

Hi George,

I have downloaded those files and will have a look now.

I have a couple of other questions in relation to this.

When users connect to this SSID and fire up their browser, they are redirected to a https page - https://1.1.1.1/login.html?redirect

Obviously the end users will receive a warning as they will not trust the certificate. The SAN on the certificate URL=https://1.1.1.1, IP Addresss=1.1.1.1

This 1.1.1.1 address maps to a virtual interface on both controllers that we have.

Why does it go to this page?

Also how do i go about getting a public cert so end users dont get a cert warning. Their are obviously dns issues.

Cheers

Re: Cisco WLC and Unsecured WLAN with redirect

Robert,

The virtual interface IP address is the IP address used by the WLC for the redirection. It will always appear on the browser address OR its corresponding name when using DNS host name is configured for the virtual interface ip address.

You need to have a certificate from a trusted CA. That CA could be your company CA or third-party CA.

Check those links for the certificate issue:

Re: Cisco WLC and Unsecured WLAN with redirect

If you do not need clients redirected to HTTPS (for example, its just passthrough and no real credentials are sent), you could just disable HTTPS for webauth instead of dealing with a cert.

Prior to 7.2 WLC code, this was accomplished by disabling secureweb on the wlc entirely (means admin login would also not use https, might be a secure concern):

config network secureweb disable

config network webmode enable

(save and reboot)

However, in 7.2 now you could simply disable https for web-auth only:

config network web-auth secureweb disable

(save and reboot).

Re: Cisco WLC and Unsecured WLAN with redirect

Hi Guys,

Thanks for the suggestions,

@Amjad - those links were perfect.

@wesleyterry - unfortunately our code level is earlier than 7.2 - this is exactly what i wanted, but looks like i will have to go the long way on this one.

I have a final question regarding the virtual interfaces - as we have two boxes each with 1.1.1.1 as their ip - can i give them the same internal dns information (ie wlcbox.domain.com) and then also install the same certificate on both. They are both in the same mobility group.

Cheers

Re: Cisco WLC and Unsecured WLAN with redirect

Actually virtual interface IP address MUST be the same on all WLCs on same mobility group.

'''snip'''

All controllers in a mobility group should have the same IP address for a virtual interface, for example 1.1.1.1. This is important for roaming. If all the controllers within a mobility group do not use the same virtual interface, inter-controller roaming can appear to work, but the hand-off does not complete, and the client loses connectivity for a period of time.

'''snip'''

Reference: http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a0080810880.shtml#mobility

So, the answer is : Yes, one entry in the DNS is enough.

Re: Cisco WLC and Unsecured WLAN with redirect

I would only add 1 snip it .. IANA issued IP adress 1.1.1.1. Should a user ever want to or need to visit that address <1.1.1.1> they will hit your wireless lan controllers. In all likley hood not going to happen. But just wantred to mention it.

Cisco recommends 1.1.1.1 be a non routed ip address, which for years was that way untill 2 years ago or so.

Re: Cisco WLC and Unsecured WLAN with redirect

Hi George,

No probs - if i change this ip on both boxes to say a 10.x address and ill stick in the dns entry, will it have any knock on effect with connected AP's.

I just want to rule out any issues with AP's associating themselves with the controller when it reboots.

Re: Cisco WLC and Unsecured WLAN with redirect

Folks,

After much deliberation - i think this is the route i will go as 7.2 is not an option for us at this time.

I have created the certificate and will let you know how i get on.

Thanks for all your help.

Cheers
