ISE Guest deployment

Hi
Im setting up a ISE (1.3) in distributed deployment with a primary and secondary node.
Both nodes are running admin and PSN role.
The 2 nodes are up and running and synchronised, and now i want to set up a CWA guest solution.
So my question is:
In case I need to do a failover to the secondary node how do we need to do the DNS registration of the portal url ?
Do I have to have a uniqe url for each ISE or do I need to set up the DNS pointing to both of the ip addresses that is set up on the interface of the ise that is used for the guest portal.
And also a seperate public cert on each ISE pointing to the CN ?
Hope my question was understandable :)

Redundancy for the sponsor portal falls into two categories. With load-balancers and without load-balancers. In both two node environments and and more than two nodes the design is the same.
With network loadbalancers you simply create a VIP for port 8443 and use the PSNs as member servers. Then simply configure the DNS hostname that is configured in the sponsor portal to the VIP.
The other options are DNS based. You can simply have two A records for the sponsor.example.com and DNS will naturally round robin between the records. The last option is to use a DNS load-balancer to accomplish the same task as the round robin, but with more control over which record is used when.
As for the cert the recommendation for using loadbalancers is to have a shared cert on all of your PSNs. the cert should contain both the FQDN of the sponsor portal and the hostnames of all of your PSNs if you are planning on using the same cert for EAP and not just HTTPS.
Here is the documentation on how to use F5 Big IP load-balancers

Need suggestion for ISE distributed deployment model in two different data centers along with public certificate for HTTPS

Hi Experts,
I am bit confused about ISE distributed deployment model .
I have two data centers one is DC & other one is as a DR I have requirement of guest access service implementation using CWA and get public certificate for HTTPS to avoid certificate error on client devices :
how do i deploy ISE persona for HA in this two data centers
After reading cisco doc , understood that we can have two PAN ( Primary in DC & Secondary in DR ) like wise for MnT (Monitoring will be as same as PAN ) however I can have 5 PSN running in secondary i.e. in DR ISE however I have confusion about HA for PSN .. since we have all PSN in secondary , it would not work for HA if it fails
Can anybody suggest me the best deployment solution for this scenario ?
Another doubt about public certificate :
Public Certificate: The ISE domain must be a registered or part of a registered domain name on the Internet. for that I need Domain name being used from customer .
Please do correct me if I am wrong about certificate understanding :
since Guest will be the outside users , we can not use certificate from internal CA , we need to get the certificate from service provider and install the same in both the ISE servers
Can anybody explain the procedure to opt the public certificate for HTTPS from service provider ? And how do i install it in both the ISE servers ?

Hi there. Let me try answering your questions:
PSN HA: The PSNs are not configured as "primary" or "secondary" inside your ISE deployment. They are just PSN nodes as far as ISE is concerned. Instead, inside your NADs (In your case WLCs) you can specify which PSN is primary, which one is secondary, etc. You can accomplish this by:
1. Defining all PSN nodes as AAA radius servers inside the WLC
2. Then under the SSID > AAA Servers Tab, you can list the AAA servers in the order that you prefer. As a result, the WLC will always use the first server listed until that server fails/gets reloaded, etc.
3. As a result, you can have one WLC or SSID prefer PSN server A (located in primary DC) while a second WLC or SSID prefer PSN server B (located in backup DC)
Last but not the least, you could also place PSNs behind a load balancer and that way the traffic would be equally distributed between multiple PSNs. However, the PSN nodes must be Layer 2 adjacent, which is probably not the case if they are located in two different Data Centers
Certificates: Yes, you would want to get a public certificate to service the guest portal. Getting a public/well known certificate would ensure that most devices out there would trust the CA that signed your ISE certificate. For instance, VeriSign, GoDaddy, Entrust are some of the ones out there that would work just fine. On the other hand, if you use a certificate that was signed by your internal CA, then things would be fine for your internal endpoints that trust your internal CA but for any outsiders (Guests, contractors, etc) that do not trust and do not know who your internal CA is would get a certificate error when being redirected to the ISE guest portal. This in general is only a "cosmetic" issue and if the users click "continue" and add your CA as a trusted authority, the guest page would load and the session would work. However, most users out there would not feel safe to proceed and you will most likely get a lot of calls to your helpdesk :)
I hope this helps!

Cisco ISE Guest Portal - DNS Issue - External Zone

Hello,
I have a customer that has the following sceanrio :
In a wireless deployment and a Cisco ISE 1.1.3 deployment with CWA, when the wireless guest receives the redictect URL from ISE (URL to access the ISE Guest Portal), this URL is based on the ISE DNS name, not on its IP address; so, the PC can't resolve this via DNS name since there is no DNS in the External zone (for guets) or by using the ISP DNS servers addresses provided by the DHCP server, and, so, it can't access the Guest Portal at all ;
I know that in trying to manually code the IP address - this does not work (ie in the CWA Authorization profile, the equivalent URL redirect via the CISCO av-pair as follows :
cisco-av-pair=url-redirect=https://10.10.10.10:8443/guestportal/gateway?sessionId=sessionIdValue&action=cwa, )
since the sessionIdValue variable is not replaced by its real value when sent to the wireless client)
My question is : Has this issue been addressed in version Cisco ISE 1.2 - has anyone tried it if has been addressed? If not in Cisco 1.2 - does anyone know iof this feature will become available?
Thank-you in advance for your replies.
Robert C.

Robert,
Manual assignment has been made available in ISE 1.2 release.

ISE Guest Portal - Error Resource not found

Hello,
When I create a guest user through the sponsor portal, then try to login with this guest user through the Guest Portal, after I press login button, the following error message occurs and do not know what to do to solve.
Error: Resource not found.
Resource: /guestportal/
None of the messages on the forum about it helped me to solve the problem.
I am using ISE 1.1.3.124 and this is a new re-image appliance.
Can anyone help?

Hello,
As you are not able to get the guest portal, then you need to assure the following things:-
1) Ensure that the two Cisco av-pairs that are configured on the authorization profile should exactly match the example below. (Note: Do not replace the "IP" with the actual Cisco ISE IP address.)
–url-redirect=https://ip:8443/guestportal/gateway?...lue&action=cpp
–url-redirect-acl=ACL-WEBAUTH-REDIRECT (ensure that this ACL is also defined on the access switch)
2) Ensure that the URL redirection portion of the ACL have been applied to the session by entering the show epm session ip command on the switch. (Where the session IP is the IP address that is passed to the client machine by the DHCP server.)
Admission feature : DOT1X
AAA Policies : #ACSACL#-IP-Limitedaccess-4cb2976e
URL Redirect ACL : ACL-WEBAUTH-REDIRECT
URL Redirect :
https://node250.cisco.com:8443/guestportal/gateway?sessionId=0A000A72
0000A45A2444BFC2&action=cpp
3) Ensure that the preposture assessment DACL that is enforced from the Cisco ISE authorization profile contains the following command lines:
remark Allow DHCP
permit udp any eq bootpc any eq bootps
remark Allow DNS
permit udp any any eq domain
remark ping
permit icmp any any

communication between NAC agent and ISE (Swiss ports)
permit udp any host 80.0.80.2 eq 8906 --> This is for posture
communication between NAC agent and ISE (Swiss ports)
deny ip any any
Note:- Ensure that the above URL Redirect has the proper Cisco ISE FQDN.
4) Ensure that the ACL with the name "ACL-WEBAUTH_REDIRECT" exists on the switch as follows:
ip access-list extended ACL-WEBAUTH-REDIRECT
deny ip any host 80.0.80.2
permit ip any any
5) Ensure that the http and https servers are running on the switch:
ip http server
ip http secure-server
6) Ensure that, if the client machine employs any kind of personal firewall, it is disabled.
7) Ensure that the client machine browser is not configured to use any proxies.
8) Verify connectivity between the client machine and the Cisco ISE IP address.
9) If Cisco ISE is deployed in a distributed environment, make sure that the client machines are aware of the Policy Service ISE node FQDN.
10) Ensure that the Cisco ISE FQDN is resolved and reachable from the client machine.
11) Or you need to do re-image again.

Cisco ISE guest portal redirect not working after successful authentiation and URL redirect.

Hi to all,
I am having difficulties with an ISE deployment which I am scratching my head over and can't fathom out why this isn't working.
I have an ISE 3315 doing a captive webportal for my guest users who are on an SSID. The users are successfully redirected by the WLC to the following URL:https://x.x.x.x:8443/guestportal/Login.action?portalname=XXX_Guest_Portal
Now when the user passes through the user authentication splash screen they get redirected to https://x.x.x.x:8443/guestportal/guest/redir.html and recieve the following error:
Error: Resource not found.
Resource: /guestportal/
Does anyone have any ideas why the portal is doing this?
Thanks
Paul

How to use ISE Guest Portal for AD users

Hi there,
As subject explains all, I want to use ISE Guest Portal for my domain users. I have tried many different ways to authenticate users and finally I came to the conclusion that ISE CWA works pretty well and is very stable. WLC Webauth sucks alot, does not redirect to the login page always.
Can you please share what other ways are stable ways to authenticate AD users? I know about WPA 802.1x authentication but that requires a CA in the network which is not available at the moment. So can you please Suggect?
Otherwise, I want to use ISE Guest Portal for my AD users as well. AD is already integrated to ISE, the issue happens when I attempt to athenticate using AD user account, the user gets authenticated but the Guest Portal redirects me to Device Provissioning page and there it shows an error saying "there is not policy to register the device, contact system admin"
Am I missing something??
I am running WLC 5760 with ISE 1.2
Thanks in advance..

Hi,
Can you post a screenshot of your current policies? Also for 802.1x authentication although it is best practices you do not have to have an internal CA to make this solution work. You can disable the option to "validate server certificate" or you can use a trusted CA to sign the certificate for the eap interface.
In most cases 802.1x is the method to go because it provides dynamic authentication without forcing users to redirected to a web page multiple times throughout the day, scenarios such as computers that sleep or users that are mobile will not have connectivity until they redirect to the portal if one of the scenarios exist. You also gain WPA encryption on your WLAN, if you are using strictly layer 3 web auth you run into issues where encryption is not used and rely on encryption from the application as your method of data integrity and security.

Guest Anchor with web auth using ISE guest portal

Hello All,
Before launching into my exact issues, could anyone confirm if they have completed a wireless Guest anchor setup using 2504 controllers on 7.4 as the anchor (5508 is the foreign) with webauth external redirection at ISE 1.1.3 using ISE Guest Services?
I am attempting this for an internal POC and have hit a couple of issues. Firstly I am looking for correct configuration confirmation prior to going in depth with a couple of the issues. I've been using the TrustSec 2.1 how to guides to build the parts I am not strong on so if anyone has actual completed this setup, I'd love to go through it with you.
massive thanks to anyone that can assist.
JS.

Thanks for the reply RikJonAtk.
so to start with, based on the trust sec documents, of the guest WLAN on the anchor I need to configure mac filtering at the layer 2 security menu as well as enable RADIUS NAC under the Advanced tab. But when I do this, I get an error message that states that mac filitering and RADIUS NAC cannot be enable at the same time.
Additionally, if I just enable the RADIUS NAC setting under the Advanced tab in the WLAN, I get another error message that states that the priority order for Web-Auth can only be set for radius, so I go to the AAA server tab and send local and LDAP to the not use column and hit apply. If I move to another menu then check the priority order again under the AAA servers tab, the local and LDAP have been moved back to the menu field to be used again. So I initially though it might be a bug, but I was hoping to find someone here that has done this already and can look at my issues and maybe walk me through their configs, which I'll mirror and see how it goes.
Thanks in Advanced,
JS

Pb to reach ISE Guest portal due to DNS constraints

I have set up a Guest Portal with WLC 5508 7.4 and ISE 1.1.1 ;
everything is OK, except one thing :
the Guest VLAN, associated to the Guest SSID is, actually, a DMZ behind my customer firewall and the DHCP parameters provided to the wireless Guest equipement connected on this VLAN include the public ISP DNS servers addresses, not the customer internal DNS serveurs addresses;
this seems OK since the idea of this Guest SSID is to give a pure Internet access to the Guests, and no connection at all towards the customer internal servers;
the problem is that, when the wireless guest receives the redictect URL from ISE (URL to access the ISE Guest Portal), this URL is based on the ISE DNS name, not on its IP address; so, the PC can't resolve this internal DNS name by using the ISP DNS servers addresses provided by the DHCP server, and, so, it can't access the Guest Portal at all ;
Apart from changing those DNS values in the DHCP server (the customer does not accept this solution), how could we solve this problem ?
I have tried to code manually , in the CWA Authorization profile, the equivalent URL redirect via the CISCO av-pair as follows :
cisco-av-pair=url-redirect=https://192.168.1.10:8443/guestportal/gateway?sessionId=sessionIdValue&action=cwa,
but, it does not work, since the sessionIdValue variable is not replaced by its real value when sent to the wireless client
any comment welcomed

We had the same issue. Our solution was to advertise the internal IP address from our external facing DNS server and let it propagate publicly. Our ISE box is in a DMZ and the firewall rules do not allow outside traffic to it, however the clients will get the correct internal IP address and since they are already inside the firewall on the DMZ segment they are able to get to the ISE box with the publicly resolved internal IP address. The other option we entertained was a firewall DNS redirect. That would work by intercepting the DNS request for that specific URL and return the proper internal IP, all other DNS requests would pass through to the public DNS server.

ISE Guest Access- Redirect to URL after successful logon

Currently, when guest users attempt to browse they get redirected to the guest portal. After login, they get a message that they can now access the original URL. Is there a way to automatically redirect to the URL they were trying to access, or remember the URL after they login?

ISE guest flow :
The user associates to the web authentication Service Set Identifier (SSID).
The user opens the browser.
The WLC redirects to the guest portal (such as ISE or NGS) as soon as a URL is entered.
The user authenticates on the portal.
The guest portal redirects back to the WLC with the credentials entered.
The WLC authenticates the guest user via RADIUS.
The WLC redirects back to the original URL

ISE Guest Port Direction not working

Hi Guys,
Got a problem here with ISE guest authentication.
My configuration in the WLC is as bellows:
And the configuration in my ISE is as bellows:
After my device connects to the SSID, I cannot be redirected to the guest portal, no redirection URL showed up in my browser, while the URL is pushed to the WLC client as bellows:
DNS A record has been added before and I can open the FQDN.
Can anyone help me about this? Thanks!
Best Regards,
Savi

Are you able to ping / nslookup to ISE.wuscnad.com from the test client?
Also, please provide a screen shot of the set of ACL's CWA-Guest from the WLC?

Using ISE guest store via RADIUS

I have a question concerning the guest store on the ISE.
I would like to establish a guest portal on a WLC (currently running version 7.0.220.0). The guest network shouldn’t have any connection to the company network. So I can’t redirect to the ISE guest portal and have to use the local portal on the WLC and pass the login data to the ISE via RADIUS. Nevertheless I want to use the guest store on the ISE.
On the ISE I can only select the internal user store as identity source. But this seems not to include the guest user store.
Has anyone already implemented a similar solution or any idea how to access the guest store?
Thanks
Thomas

I just created a simple setup and tested the login.
It doesn't work with a user created as a guest account.
If I create the user in the normal internal identity store I works fine.
Might there be a difference between ISE Versions?
We are currently using Version 1.1.0.665 on a VM for testing purpose.

ISE Guest - Change Password Option

Hi All
Can anyone confirm that the change password option on the Guest Self Registration Portal actually works?
I have enabled the options with the ISE Guest Portal to allow the Guest to create his own account and also to change his password.
Although the self creation of the account works fine it doesn't look like changing the password works. When you enter the new password and click submit nothing seems to happen.
ISE version is 1.2.1.198
Regards
Roger

Hi Roger,
Are you making use of customized self registration portal. In such cases make sure , the session ID of a particular guest login is carried forward to the password change page as well.
For the html changes to any pages (login, aup, self_registration, self_registration_result,
device_registration & change_password) that link back to other pages. The below points A and B should be added as part of customized pages.
A)Reference script (<script src="js/customportals.js"></script>)
B)Add the onsubmit="getDynamicAction(this);" logic for posts
Thanks

ISE HA Deployment prerequisite issue.

I encountered this HA node deployment issue.Actually , I finished this feature with the enviroment of CA and DNS.However,Can I finish ISE‘s HA deployment without CA and DNS.
When I adding the second ISE node to the first one,I fill the blank with the second ISE's server IP address,the system notification indicates that Unalbe to authenticate xxx.Please check server and CA certificate configuration and try agian.
After that notification, I deploy the CA and DNS server.Also I signed the certificate and install the root CA for both ISE nodes,DNS records also be done.After that,I fill the blank with second ISE's FQDN and administration account .It can be done successfully.
So if my enviroment doesn't have CA and DNS.Does that mean I can't finish ISE'S HA function?
Any help or suggestion will be appreciated!

Hi,
You can not do ISE HA deployment without CA and DNS.
DNS : When you upgrade a complete Cisco ISE deployment, Domain Name System (DNS) server resolution is mandatory; otherwise the upgrade will fail.
CA : During the split deployment upgrade, before you register the nodes to the new primary Administration node, you must do the following:
-If you use self-signed certificate, you must import the self-signed certificate of all nodes to your new primary Administration node.
-If you use different CA certificates for the nodes, you must import all the CA certificates into the new primary Administration node.
-If you use the same CA certificate for the nodes, you must import that CA certificate into the new primary Administration node.

ISE Guest Portal and one more SSID using internal accounts

Hi Guys,
I have two SSIDs on WLC, the first is related with ISE Guest Portal and the second is related with employee but i realize that the
Guest user can access the employee SSID and employee accounts can access the Guest portal page.
I guess this is happen because i cannot split these databases under "Internal Users" on Authentication Policy.
How can i restrict the access even if i am using the internal databse?
thanks a lot

using the Authorization policy is the right way. Match the corp ID store to the corp WLAN SSID ID in the AuthZ policy, for example (where Employee is your corp ID store and yyyy is the name of your corp SSID):

Cisco ISE guests and Ironport

Hi All,
I'm currently writing a HLD for a Cisco ISE rollout in my organization, and I've come across sort-of-an-issue:
I'm planning on getting the guests in through the ISE Guest portal, but I also want to push them through an authenticated proxy(for accounting purposes) instead of a transparent one... however, I can't seem to find a way to somehow integrate Ironport and ISE in order to achieve some sort of an SSO, to avoid users having to enter their credentials twice(guest portal and ironport)- has anyone got a working solution for this?
Any constructive input appreciated!
Thanks!

Thanks for the swift responses and suggestions!
I'll most certainly have a look at the proposals...
However, I still want the guest users to go through the S370, as it's not only for accounting purposes, but I want them to authenticate, since it would make tracing and pinning events to a person way easier - that's the main reason why I'm trying to find a solution that might act like an SSO. The business side stated that signing in twice(ISE guest portal, then proxy) is unacceptable. I know that there's no direct integration between ISE and Ironport at the moment, and I am going to put in a feature request for that, but for the time being, I am really keen on getting this to work somehow...
BTW - I'm currently using a virtualised ISE, release 1.1.4., And I've got the 3395's on order...
