Cisco Firewall :: ASA 5500 - Installed New SSL Certificate But Clients Seeing Expired One

Feb 21, 2012

I have installed a new SSL certificate on our ASA 5500. I removed the old one, installed the new one. And associated the trust points with the interface we use for Web Connect and Any Connect connections.
 
They are still seeing the old expired certificates. Users can still log in and authenticate but I would rather them see the correct certificate.

Linksys Wireless Router :: E3000 / Expired Certificate After A Power Cut?

Mar 4, 2012

I have a cisco E3000 with firmware version 1.0.04. I enabled the Local Management Access with HTTPS. If I connect to the HTTPS management interface, I can see that the date of validation of the HTTPS certificate is valid.If I disconnect completly my router (disconnect the power supply), it seems that the HTTPS certificate is regenerated for the boot. The problem is that it is regenerated with a validation date from 01/01/1970 to 01/01/1971. I guess that the certificate is generated before the router is able to automatically set its own time.

Cisco AAA/Identity/Nac :: Getting Certificate Installed - ACS 5.2

Jun 14, 2011

Currently I'm using a self signed cert issued by ACS. We are having an issue where occasionally we see in our Windows 7 logs that Windows did not like the self signed cert from ACS when doing dot1x authentication for our Windows 7 clients. We are using the built in dot1x client that comes with Windows and have the "Validate Server Certificate" unchecked but still see this error occasionally. I've tried issuing a CSR from the ACS server and going to Thwate and getting a test cert but everytime I paste the CSR into the field at Thwate I get an error about invalid cert type. You have to choose from a list of server types. I've tried several different ones. I've also tried issuing the request from a WIndows server and when I try and import the files I get a invalid key error. How to get certificate working from Thwate or Verisign?

Cisco VPN :: No Password Prompt From ASA 5500 For Certificate Enrollment?

Apr 11, 2013

I work in a lab testing interoperability between Avaya and Cisco VoIP products.I am setting up an environment to test Avaya 96x1 phones with VPN using SCEP going thru an ASA 5510 to a backend IP PBX. 
 
Environment:  Windows Server 2008 R2, Enterprise Edition, AD with DNS, NDES Cisco ASA 5510 running 9.0(1)
 
I would like to setup certificate enrollment between a Windows Server 2008 R2 and a Cisco ASA 5510.  Here are the commands that I use for the Cisco ASA 5510:    

crypto key generate rsa modulus 2048     crypto ca trustpoint ASA5510-trust         enrollment url http://10.129.112.20/certsrv/mscep/mscep.dll         enrollment retry period 5         enrollment retry count 3         password Interop123         exit     crypto ca authenticate ASA5510-trust     crypto ca enroll ASA5510-trust
 
Everything works as expected until I try to enroll. There is no prompt for the enrollment password and the certificate request is denied.
 
ciscoasa(config)# crypto ca enroll ASA5510-trust%% Start certificate enrollment ..% The fully-qualified domain name in the certificate will be: ciscoasa.avayasil.avaya.com% Include the device serial number in the subject name? [yes/no]: NoRequest certificate from CA? [yes/no]: yes% Certificate request sent to Certificate Authorityciscoasa(config)# The certificate enrollment request was denied by CA!
 
Why isn't there a prompt for the enrollment password?BTW, If I set "enforcepassword" to "0" in the Windows registry, then it works.

Linksys Wireless Router :: Installed E3000 Now VPN Clients Could No Longer Connect

Nov 3, 2010

I had a simple PPTP VPN server running behind my old DLink router.  When I installed the E3000 the VPN clients could no longer connect.  The port forwarding for PPTP is turned on and VPN passthrough is enabled. The PPTP server reported GRE47 checksum failed.  The linksys chat tech was not beneficial.  How to get a PPTP route to work?

Cisco :: WCS 5500 Should Clients Associate With APs With Highest Signal Strength

Aug 10, 2011

I have one room within which clients have problems associating.When using AirMagnet however one of the AP s appears to have the strongest S/n Ratio and overall signal strenght.I would have thought that would be the obvious AP for clients to associate with.However that is not the case and the users are trying to associate with various APs with lesser signal strengths. None of them have 100 % utilisation and if they all tryed to associate with the AP with the strongest signal that would alleviate the existing association problems. We are using AIR-CAP3502E-E-K9 with WCS 5500.

Cisco AAA/Identity/Nac :: 5508 / ISE / BYOD / Windows Clients Reject ISE Local-certificate

Mar 26, 2013

We are deploying BYOD with Cisco ISE 1.1.2 and WLC (5508) using 802.1x authentication.Windows clients cannot connect to 802.1x SSID with the following error on ISE:Authentication failed : 12321 PEAP failed SSL/TLS handshake because the client rejected the ISE local-certificate
 
The client doesn't have preconfigured wifi profile or root certificate installed.The concept of BYOD suppose that you can connect your device without any installed certificates and preconfigured wifi-profiles.
 
The problem is that Windows 7 supplicant does not send TLS alert in pop up window, when connecting to 802.1x SSID.If this alert is seen, than you can accept it and proceed the connection. After that you will be asked to install ROOT-cert, get your own cert and etc.So, the question is: how to make the windows supplicant to show the pop-up window with TLS alert?

p.s. the attached file shows the example of pop up TLS-alert window

Cisco VPN :: All Remote Wireless IPSec Remote Clients Fail Connecting To ASA 5500

Sep 12, 2012

We have two ASA 5500 series Firewalls running 8.4(1).  One in New York, another in Atlanta.They are configured identically for simple IPSecV1 remote access for clients.  Authentication is performed by an Radius server local to each site.
 
There are multiple IPSec Site-to-Site tunnels on these ASA's as well but those are not affected by the issues we're having.First, let me start with the famous last words, NOTHING WAS CHANGED.
 
All of a sudden, we were getting reports of remote users to the Atlanta ASA timing out when trying to bring up the tunnel.  They would get prompted for their ID/Password, then nothing until it times out.Sames users going to the NY ASA are fine.After extensive troubleshooting, here is what I've discovered. Remote clients will authenticate fine to the Atlanta Firewall ONLY IF THEY ARE USING A WIRED CONNECTION.
 
If they are using the wireless adapter for their client machine, they will get stuck trying to login to Atlanta.These same clients will get into the New York ASA with no problems using wired or wireless connections.Windows 7 clients use the Shrewsoft VPN client and Mac clients use the Cisco VPN client.  They BOTH BEHAVE the same way and fail to connect to the Atlanta ASA if they use their wireless adapter to initiate the connection.
 
Using myself as an example.
 
1. On my home Win 7 laptop using wireless, I can connect to the NY ASA with no issues. 
 
2. The same creditials USED to work for Atlanta as well but have now stopped working.  I get stuck until it times out.
 
3. I run a wire from my laptop to the FiOS router, then try again using the same credentials to Atlanta and I get RIGHT IN.
 
This makes absolutely no sense to me.  Why would the far end of the cloud care if I have a wired or wireless network adapter?  I should just be an IP address right?  Again, this is beyond my scope of knowledge.We've rebuilt and moved the Radius server to another host in Atlanta in our attempts to troubleshoot to no avail.  We've also rebooted the Atlanta Firewall and nothing changed.
 
We've tried all sorts of remote client combinations.  Wireless Internet access points from different carriers (Clear, Verizon, Sprint) all exhibit the same behavior.  Once I plug the laptops into a wired connection, BAM, they work connecting to Atlanta.  The New York ASA is fine for wired and wireless connections.  Same with some other remote office locations that we have.
 
Below I've detailed the syslog sequence on the Atlanta ASA for both a working wired remote connection and a failed wireless connection.  At first we thought the AAA/Radius server was rejecting us but is shows the same reject message for the working connection.  Again, both MAC and Windows clients show the same sequence.Where the connection fails is the "IKE Phase 1" process.

Cisco Wireless :: 2500 / 5500 - Wireless Access Point Identification By Clients

Apr 30, 2012

We have recently been given this unusual task.  The setup is a series of CAP3502P access points, and a wireless controller (either 2500 Series or 5500 Series), as well as other standard network infrastructure.
 
In this network, the client (mobile/wireless) devices must be able to detect when they change what access point they are communicating through, while also requiring a seamless transition.  Ie, if the client device is communicating via access point A, and displaying the application menus for A, when the user walks to the area services by access point B, it must detect that sot he application can display menus for B, without the user having to select "B".
 
Is there a way for the client device to detect which access point it is using and provide that to an application? Or alternatively a way for a host service residing on a server to get that information from the wireless controller?

Cisco Firewall :: Support Of Jumbo Frames On ASA 5500 Firewall Appliance?

Feb 28, 2010

Can any ASA 5500 in particular the ASA5510 firewall support jumbo frames (i.e. greater than the default standard 1500 Bytes frames)?. I plan to use the ASAs to setup a point-to-point IPSec tunnel and need an Application frame of 4Kbytes intact and not segment it.I have done little checking on the Cisco Website and see it mention of Jumbo frames on the 5580 on 10Gig interface but didn't see mention 5510. 5580s are way over-kill and expensive for what I need is to run a mission critical one IPSec point-to-point with maximum of no more than 100Kbps so 5510 is perfect for me but not sure if it can carry the jumbo frame?
 
On the routers and switches it's the MTU settings and they are configurable per interface and I am OK and the circuit is T1 which the Telcos said it's OK since it's physical layer so the only unkown is the firewall.
