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.

I migrate 1310 APs from Autonomous to Lightweight. Migration is OK with Cisco Upgrade Tool, and AP are registered on my 2504 WLC.
Previously, a 802.1x network was broadcasted by autonomous APs, supplicants were identified on a freeradius server with MSCHAPv2/PEAP method.
But on the WLC, supplicants can't auth on Radius server.I configured a WLAN with WPA/TKIP/802.1x with my radius server in AAA tab.When clients try to authenticate, I get these messages where xxx is login:
-AAA Authentication Failure for UserName:821 User Type: WLAN USER
-AAA Authentication Failure for UserName:200 User Type: WLAN USER

What is strange, there are some clients which are OK in RUN State, and 50 other % which are not.

I have a remote access VPN profile configured on an ASA 5540. This profile is almost identical to the same profiles configured on other ASA 5540. The profile is linked to Active Directory for authentication. For some reason, users are not being prompted for the domain name field when connecting to the firewall, on the other firewalls they get prompted for all three (user/pass/domain).
All the firewalls are running 8.0(4) 32. And the following is the configuration of the firewall that I am experiencing issues with:
ip local pool TESTVPN 10.244.124.1-10.244.127.254 mask 255.255.252.0

I need some clarification with configuring my ASA 5540 with IOS 8.3x for remote client certificate authentication.
I have my root certificate from the Microsoft CA but not quite sure if the outlined steps in the Cisco websites below are exactly what I need since the firewall seems to be generating the certificate to be used. [URL].
My setup is such that the CA will issue certificates to the remote clients and to the ASA firewall, and the remote clients will authenticate and connect with their certificates which the firewall constantly updates using the CRL update from the CA. The dhcp pool is to be issued by the domain controller on the inside network and not on the firewall. Any examples or best practice steps to achieve this.
I follow step by step the link bellow to configure web-auth with external RADIUS server but I receive a error on console debug of the WLC "Returning AAA Error No Server (-7) for mobile"My Radius Server is fine, because I can authenticate on WLC Web page with RADIUS user.

I have a c2969-48PST-L switch running IOS Version 12.2(55) SE. The switch is configured for 802.1x authentication. The radius server is a Cisco ACS 5.2. We are using PEAP and allowing EAP-TLS and EAP-MS-CHAPv2. Windows 7 PCs (HP Elitebooks) are using the "windows" supplicant and configured to 802.1x authentication is enabled using Microsoft Protected EAP (PEAP), we are not validating any certificates and the authentication method is Secured password (EAP-MSCHAP v2). What is occurring every so often is that the PC will fail authentication (intermittently) and the ACS shows the reason as being 5411 EAP session timeout. This is a pretty generic message according to TAC. The interesting part to me is the Authentication Method showing on the ACS when the authentication fails is simply PEAP. However, when it does not fail the Authenication Method is shown as PEAP (EAP-MSCHAPv2). We have the Cisco TAC looking at the ACS and they are saying the issue is the client not reponding to the request correctly from the switch.if the version of IOS softare on the switch maynot be handling the communication to the ACS correctly. I have wireshark traces of a successful authenication and unsuccessful one. There does seem to be any difference from the client side at all.
View 1 Replies View RelatedI am getting the below error on my new switch though I can’t find out A. why I am getting the error and obviously B. how to resolve said error as I need to ensure I am operating under the letter of the law and compliance. The switch is a WS-C3750X-48T-S running C3750E-IPBASEK9-M, per my research IP base is the correct IOS for a T-S switch, the label on the outside of the switch matches the show ver (WS-C3750X-48T-S) so I know that IPBase is the right IOS for the hardware. Could it be that I don’t have the license file installed? Below is what I get when I do a show license. Lastly is there a place that I can find what IOS ships default with what switches, not version but type like c3750e-ipbasek9-mz.150-1.SE vs c3750e-ipbase-mz.150-1.SE

I have two Firewalls one on MAIN site and another on BR site. I have configured RA VPN for both and i am able to access the internal networks of respective Firewalls. But the requirement is i want to connect to the Main site through RA VPN and access the BR SITE internal networks through that connection.
View 4 Replies View RelatedI am currently running an ASA5540 version 8.3(2). I have multiple remove vpn users currently working on this server. Lately, I have had issues with people getting booted or not being able to route anywhere and it appears to be cause they keep fighting for the same IP address using the local pool, so I decided to attempt to do DHCP instead (I have no idea why it keeps overlapping IPs, we have tons in the pool and they keep fighting for the same one). This just started about a month ago, we are only using maybe 3-5 IPs out of the /24 block. The only thing that has changed was we have hired more people, but we have separate groups for corporate vs operations team.
So, I setup the dhcp-network-scope for the subnet and the dhcp-server under the policies. I see the request going to the server, but it seems to be putting the ASA MAC into the Client Hardware Address field of the DHCP header. I have attached the PCAP from the ASA showing this.
I have a setup with a were I configured monitor mode on a switch with ISE as RADIUS server. This is for testing before a bigger deployment at a customer site.Im using ISE 1.1.3, C2960 and IOS 15.0(2) and a laptop with Windows 7 Enterprise SP1. The correct configuration with EAP-TLS and machin cert is working like it should but it is when I remove this and make the laptop fail that I get wierd results with monitor mode. I cant get DNS to work in dot1x monitor mode if the client fail authentication.
When the client fail dot1x and MAB it gets a IP with DHCP. I can ping but DNS/browsing is not working. If I put the AuthC back and the client authenticates DNS is working, or if I turn of dot1x on the client then DNS work as it should. [code]

I'm trying to set up remote access IPsec VPN on a pair of ASA 5540 without much success. I can connect with a client on the outside, and when I try to ping something on the inside I can see the ping requests reach the target but the answers don't come back to the VPN client. I've tried with different NAT rules without success.

Furthermore, we cannot ping any as well. Also, while connected the Windows 7 machine is still able to access internet site as if split-tunneling was configured, which its not.
But after some searching , i found from "routeprint" output (shown below ) that my local internet gateway is prefered over the VPN gateway which is 10.10.4.1.Here 10.10.4.19 is the IP address assigned for VPN adaptor.

But after i manually add the below route on windows 7 laptop , it started connecting to remote desktop successfully.
route change 0.0.0.0 mask 0.0.0.0 10.10.4.1 metric 20
But aftersome time of idle state , it is again going back to original route state of prefering the local gateway of 192.168.1.2 and thus unable to connect to Remote Desktop again.

We have a problem with an existing L2L VPN connection. The connection has to this day served only connections originating in one direction. Meaning only one end initiates the connections. This has worked normally so far. Now the third party behind the L2L VPN also wants to access some resources trough the L2L VPN and because of that also initiates the connections. This is where we face our problem.
For some reason the remote end cant bring up the L2L VPN where as we can (and the second party in our end of course). The connection was originally on a Cisco 6509 WS-SVC-IPSEC-1 module. For the tests in new equipment we moved the connection to a Cisco 7609 with SPA-IPSEC-2G module. The remote end uses Checkpoint FW1 R70 (or something like that. I'm not familiar with Checkpoints) With both equipment the problem remains. We did the tests today and i took some debug messages on our end with "debug crypto isakmp" and "debug crypto isakmp error" enabled. I also enable the "debug crypto condition peer ipv4 x.x.x.x" for the debugs as there are several other connections on the same device. This is what the debug shows (Remote end IP replaced with x.x.x.x):

To my eye it seems that the attributes/parameters for Phase 1 are OK on both ends (have to be since the connection forms normally when the traffic is initiated from our side) but somewhere along the way the negotiations stop because our end gets a malformed packet during the negotiations? Does this mean the remote end is somehow faulty? Is there some compatibility problem with the VPN devices in question? or its the sign of some known problem with VPN connections? So far I have not found any explanation to what is causing this.
I just purchased 5 RV220W to act as internet/wireless router at a remote site. There is no VPN, just LAN and Wireless routing to the internet.I have setup remote management and it works fine when I am directly connected to the internet. However, everytime I try to connect through our HTTP/HTTPs proxy farm, it usually fails. Specificially, I get the log-in page and can log in. It starts to render the landing page but redirects to a page stating "Your session has been terminated." On rare instances the first page will appear, however within a few clicks I end up with the same terminated page.
As a test, I bypassed the farm and forced my browser to use one proxy exclusively. At that point I could access the HTTPS interface with no issue. I have not had any issues with other SSL sites with the proxy configuration in use.Is there some sort of MITM prevention I could be running into? If so, can it be turned off.I am new to the RV-series of routers. Is there any logging I could turn on that would provide insight on why the session may be getting terminated?

View 2 Replies View RelatedJust upped our external ASA-5540 pair to 8.4(1), and now one of our nat's is busted.
Here's the lowdown:
Our public IP for our IronPorts ends in .167. That IP is natted to a VIP on our ACE, which load balances to the IronPorts.
The outside interface of the ASA uses .162, which has been the pat for all outbound traffic for a few years... except for the subnet that houses the IronPorts. Due to reverse lookup, that subnet uses the .167 IP address for all outbound traffic.
After the code upgrade, the nat won't work. No email sent or received. Nothing but Deny's on the ASA with flags reading either "SYN" or "RST". IE: Apr 27 12:56:11 10.22.151.41 local5.crit %ASA-2-106001: Inbound TCP connection denied from 69.25.174.17/36917 to 207.236.211.167/25 flags SYN on interface outside
If I return the subnet pat back to the outside interface, then inbound traffic works fine, though reverse lookup fails and anyone running a reasonable spam filter won't send to us.
I have two Cisco ASA 5540, these ASA running ver 7.2. and used mainly as VPN gateways.My question is simple, Apart from the extra AnyConnect client functionality and the higher encryption, is there any specific security benefits (related to the VPN use) for upgrading to ver. 8.x ?
