NAC guest server-user poster assesment problem

Dear all,
Please assist me for NAC guest server poster assesment issue.
Scenario is like we have NAC guest server and all wireless guest users authenticate through Guest Server.
Its working fine.
But customer wants to apply poster assement on guest users through existing CAS and CAM.
Guest_users-------AP-------WLC------- NAC_Guest_Server----------internet

Thanks for reply.
Actually in my network we have cas and cam integrate with WLC for internal users. Its working fine.No issue. Poster assesment and authentication working fine.
We have also NGS server which is integrate with WLC for web authentication fow guest wireless users.
It is also working fine.Authentication happened through NGS server succesfully.
But now I wanted to force poster assesment for wireless guest users which are authenticated through NGS server.

Guest Wireless Users Not Able to Get to NAC Guest Server

First of all, I appreciate any of the help that can be offered on the post. Your solutions and suggestions have been valuable, in the past!
Here's the scenario. I have two internal WLC's, and one anchor mobility server, in the DMZ. The internal controllers are part of the 10.x.x.x range, while the DMZ WLC is in the 192.168.1.x range. We also have a NAC Guest Server, in the DMZ that has a 192.168.1.x address. Here's the problem, when a guest user uses our guest SSID, they're assigned a 172.16.x.x address, their traffic is intercepted, and they're presented with a login page. If they don't have login credentials, there's a "Register Here" link that takes them to the NAC Guest Server to self-register. When they click the "Register Here" link, for some reason they can't get to the NAC guest server. If I bring up a command prompt, and type in "telnet 192.168.1.x 80", it connects. The odd thing is that when I was testing, if I login with guest credentials, and then try to go to the NAC Guest Server self-service page, I can get to it with no problem. Would anyone have any ideas as to why?

I may have missed something here, but isn't the point of the guest portal that you can't get anywhere on the network (except the guest portal) until you have authenticated?

NAC Guest Server, How to change the password for a single user?

We have a NAC Guest Server which creates a complex password for all new users created.
We would like to have normal/simple password for a single user. How can I get this done on a NAC Guest Server.
Thanks in advance.

Hi,
You can setup 3 different flavours of passwords:
http://www.cisco.com/en/US/docs/security/nac/guestserver/configuration_guide/20/g_guestpol.html#wp1063249.
a. Username Policy 1 - Email address as username
Use the guest's email address as the username. If an overlapping account with the same email address exists, a random number is added to the end of the email address to make the username unique. Overlapping accounts are accounts that have the same email address and are valid for an overlapping period of time.
b. Username Policy 2 - Create username based on first and last names
Create a username based on combining the first name and last name of the guest. You can set a Minimum username length for this username from 1 to 20 characters (default is 10). User names shorter than the minimum length are padded up to the minimum specified length with a random number.
c. Username Policy 3 - Create random username
Create a username based upon a random mixture of Alphabetic, Numeric or Other characters. Type the characters to include to generate the random characters and the number to use from each set of characters.
Note: The total length of the username is determined by the total number of characters included.

Cisco NAC Guest Server for Wireless Users integration with IP telephony

Hi Team
I have a client who has the following requirement. The cleint requires a Guest server inorder to serve wireless needs for guests at their office. They want the guest to get their authentication codes via SMS. The cleint will have a lobby IP Phone where the guest will press the services button confgiured on the IP Phone. IT will then prompt the guest to enter his mobile number. Once the guest enters his mobile number, the guest will recieve a text via sms gateway with login credentials. They want to offload this from the receptionist and it is for this reason that they require this functionality.
Has anyone done this sort of deployment ? We have already proposed NAC guest server and Wireless controller but we do not know whether the XML application for subscribing the service on the IP Phone is available directly with cisco or does it need to developed.
Kindly advice on the same.
Regards
Azeem

Hi Vishal,
Please note that if you want to return ACLs (and usually in wired web auth you need to), you will have to integrate with ACS as NGS itself cannot return ACLs in the reply radius attributes.
Basically the process is as follows:
1 - Client plugs cable on switch.
2 - Web auth is triggered on the port.
3 - default ACL permiting only DNS and DHCP is applyed so that the client PC can obtain IP address and open a browser.
4 - Client will be redirected to the NGS hotspot login page.
5 - Client will enter credentials.
6 - Client broswer will send an HTTP POST packet containing the credentials.
7 - The switch will intercept the POS packets and retrieve the credentials entered.
8 - The switch will send Radius Access-Request to the ACS.
9 - The ACS will use the NGS as External Identity source to authenticate the client.
10 - The NGS will reply with Radius Access-Accept to the ACS and the ACS will reply to the switch including the ACL in the Access-Accept.
11 - the Switch authorizes the client on the port and applies the ACL it received from the ACS.
Please follow the document Nicolas posted as it is a good one.
HTH,
Thanks

Wired WebAuth only with NAC Guest Server (No ACS)

Ok, I have been fighting this for two days now. I want to use the webauth function on some of our Cisco 3750Gs ver
12.2(55)SE5 for guest access. I'm trying to use our NAC Guest Server ver: 2.0.3 as the backend portal and Radius server. We do not have ACS or any of the other components of ISE or NAC. I think the issue is the NGS server is not sending the d(ACL) back to switch. Guest work work fine from our WLCs.

NAC Guest Server - Self Service

Hello all,
I have a problem with NAC Guest Server and the self service feature.
When I use the self service feature with auto login it works fine.
But the customer would like to disable the auto login feature and the guest has to fill in his username /password.
These credentials will created by the NAC
When I click "add user", there is the message: user successful created.
but I don't have the possibilty to reach the login page with username/password with my browser.
But There is no redirect to the login page with username/password and when I refresh the browser or restat my browser, I will always reach the "self service" page.
I hope someone had a similar problem and can help.
thanks
Martin

have you allowed pop-ups on the browsers?
did you try switching the browser?

NAC Guest Server and WLC's

Just wanted to know if this will work or not...
I was looking at a design from a client and they had two CAM and CAS plus a Guest server. My client wants to use the equipment above for guest access. The problem I'm having is that I'm building a wireless network with guest anchor WLC's in the DMZ. So my wireless users will be tunneled to the DMZ controller. Also, the WLC can have a splash page uploaded to it and also authenticate users locally in the DB. They don't want any remediation, just authentication.... is this a waste of money or would would actually implement this?

I've some (very) basic questions.
Let's say guest vlan = x
1)vlan x should be created on the foreign controllers as on the anchor controller, with the same properties
2)on the anchor controller a dynamic interface has to be created acting as default gateway for the guest clients.
3)it's advised to place the guest server in the guest vlan? Eg. Somewhere in the server farm?
4)Once traffic coming from the guests is arrived at the anchor controller. (I know to less of WLC ;)) Will it forwarded with as source IP, the IP of the anchor controller towards the anchor default gateway (firewall or internet router?)
4)authentication: user connect to SSID guest and opens a browser. The user is redirected and a login page is displayed. Is this page downloaded from the anchor controller? I think it is and pushed via WCS. So Guest NAC server has nothing to deal with this page? Correct?
The anchor controller polls the nac guest server with the given credentials. Anchor controller forwards the credentials to the NAC guest server. The NGS replies with authenticated or not. If authenticated. The guest can browse. Probably on regular base, the anchor controller will poll the NAC guest in order to check if he's still authenticated and if enabled pass information to the NAC guest for accounting. Is this somehow ok?
I've found to open the following ports in the firewall:
UDP 97 for EoIP
UDP 16666 for intercontroller traffic
and 1812/1813 for Radius.
Thanks in advance

NAC Guest Server, unable to login with sponsor

We have a Cisco NAC Guest Server (version 2.0.5).
I created some sponsors and wanted them to be in another sponsor user group than the default group. So I created a sponsor user group and changed the group permissions (Allow Login is set to Yes, edit account .. are set to Own Accounts).
No I wanted to try out the new sponsors but I can't login to the NAC Server. I get a "username or password invalid" as reply. If I change the sponsor user group of the user to DEFAULT, everything is working.
The logfile on the NAC Server shows the following error:
Oct 4 13:05:14 s100059 NGS_SPONSOR: [audit NGS 0 10.106.161.5] Login failure: xxx
xxx is the username of the sponsor.
Why can't I login with the sponsor when he's in anoter sponsor group than DEFAULT?
Martin

If credentials work on CCMuser CUPSuser I would suspect either some kind of communication problem between the clients and the servers and/or misconfiguration (user/device/line association, device owner, roles, CTI/CCMCIP profiles, etc) on CUCM/CUPS.
Specially because you mention the same happens with CUPC.

NAC Guest Server- Can port redundancy be acheived ?

Dear Folks,
I do have NAC Guest Server which i need to deploy for wireless clients (guest users ) . I want to connect to two core switches. Can I establish redundancy on it . I checked in documentation, as it says to configure IP in eth0 to connect to the network . Is there any feature like teaming can be deployed?
Regards,
Aaron

We had the same problem.
You can solve sending to RADIUS Server (Cisco NGS) this additional radius attribute:
Calling Station ID
NAS IP Address

NAC Guest Server SMTP Authentication

Does anyone know if you are able to set your SMTP server in the NAC Guest Server to do SMTP Authentication? Our old Exchange server just let us specify the SMTP server and send the guest accounts their Username and Password to their outside accounts. Our new Exchange server requires SMTP authentication, but we do not see the option available in the NAC Guest Server interface. We are running NAC Guest Server 1.1.3. Any ideas would be appreciated. Thanks!

I have Cisco NAC Guester server 2.0.2 and have sort of similar issues.
I configured the Base DN to the OU of the sponsor groups in AD and then map that particular group in roles. Users from that group can log on fine and create guest accounts.
The problem is, it seems that other users from that OU seems to be able to log on as sponsors too. How do I restrcit this to just that sponsore group? I tried changing the Base DN to the OU of the sponsore group then enter CN=sponsorgroup to narrow it to just that group but still other users can log in as sponsors.

NAC guest server with RADIUS authentication for guests issue.

Hi all,
We have just finally successfully installed our Cisco NAC guest server. We have version 2 of the server and basically the topology consists of a wism at the core of the network and a 4402 controller at the dmz, then out the firewall, no issues with that. We do however have a few problems, how can we provide access through a proxy without using pak files obviously, and is there a way to specify different proxies for different guest traffic, based on IP or a radius attribute etc.
The second problem is more serious; refer to the documentation below from the configuration guide for guest nac server v2. It states that hotspots can be used and the Authentication option would allow radius authentication for guests, I’ve been told otherwise by Cisco and they say it can’t be done, has anyone got radius authentication working for guests.
https://www.cisco.com/en/US/docs/security/nac/guestserver/configuration_guide/20/g_hotspots.html
-----START QUOTE-----
Step 7 From the Operation mode dropdown menu, you can select one of the following methods of operation:
•Payment Provider—This option allows your page to integrate with a payment providing billing system. You need to select a predefined Payment Provider from the dropdown. (Refer to Configuring Payment Providers for details.) Select the relevant payment provider and proceed to Step 8.
•Self Service—This option allows guest self service. After selection proceed to Step 8.
•Authentication—This option allows RADIUS authentication for guests. Proceed to Step 9.
----- END QUOTE-----
Your help is much appreciated on this, I’ve been looking forward to this project for a long time and it’s a bit of an anti climax that I can’t authenticate guests with radius (We use ACS and I was hoping to hook radius into an ODBC database we have setup called open galaxy)
Regards
Kevin Woodhouse

Well I will try to answer your 2nd questions.... will it work... yes. It is like any other radius server (high end:)) But why would you do this for guest.... there is no reason to open up a port on your FW and to add guest accounts to and worse... add them in AD. Your guest anchor can supply a web-auth, is able to have a lobby admin account to create guest acounts and if you look at it, it leaves everything in the DMZ.
Now if you are looking at the self service.... what does that really give you.... you won't be able to controll who gets on, people will use bogus info and last but not least.... I have never gotten that to work right. Had the BU send me codes that never worked, but again... that was like a year ago and maybe they fixed that. That is my opinion.

NAC guest server and pre-configured duration of accounts

There seems to be a bug in the way the NAC guest server handles the pre-configured duration of guest accounts.
I have followed the manual and I did:
- Configured 3 durations (24h, 48h and 1 week) under the templates/accounts/accounts durations.
- And set "maximun duration of account" under User Groups
As I understand I should now be able to select one of the three configured durations when I login as a sponsor.
However I only get the number which I specified under User Group.
The odd thing is that if I change the Maximum duration under User Group, I get this as the only choice (e.g. 14 days).
Have other experienced this?
Best regards,
Steffen Lindemann

You can use any one of the option ie number of days or number of hours.
For days;
Authentication > User Groups > Add Group | Edit Group includes two new settings for Number of days in the future the account can be created and Maximum duration of account (in days)
For hours:
User Interface > Templates > Add Template | Edit Template > Accounts > Account Duration

NAC Guest Server 2.0.5

Hello Everybody,
We have NAC Guest Server version 2.0.5, our customer has two requeriments, one of them is to assign manually password to a new account, the second is change the state inactive of the account to active state. As I saw in this version, i can't do it.
Is possible to do both requeriments on a later release of NAC Guest Server?
Thanks

Sri,
You are right this isnt well documented. My guess is that you will download the same upgrade file from cco for the upgrade to 2.0.3 and then follow the same steps. However, that is something that should be documented. Can you open a TAC case and have them file a documentation bug for this.
Thanks,
Tarik Admani
