View 3 RepliesI am having trouble with a newly configured install. Basically it seems that my centrally switched guest SSID is not functioning. As you change AP groups, which should change the interface associated with the SSID and also the dhcp client address, the client is retaining the original dhcp address from whichever AP group they first associated with.
I also have a locally switch WPA2 SSID at each location which is working fine. Clients are able to change dhcp address correctly as they move between AP groups. It just doesn't seem to be working on the guest network, which is odd because it was working earlier in the install. It has only started having issues yesterday afternoon.
The interface above is assigned to the guest SSID in one of the AP group. I assume this has something to do with it but I've been over my DHCP assignments on the core switch, local switch, controller, and dhcp server and can find no issue with the configuration..
I am not sure why as I am not using DOT1X at all. The guest is a pass-thru and the WPA2 network is just WPA + WPA2 with TKIP and AES. No DOT1X anywhere on the controller...

These are only occuring for clients that are disconnecting....
They can reconnect after a WLC reboot....
We have swapped APs.....
I have seen this error in other forums but it says not to worry about it. There has to be a connection between this and clients getting disconnected. We have anywhere between 10-50 clients on the system at any one time.Is this a client issue (nic firmware, version) or is this an error in the controller??

I am having this problem trying to connect to my university network trough the vpn client from a pc running Windows 7 Ultimate 64-bit: the client connects but I have no Internet access. I first believed that the problem was related to the fact that I had ZoneAlarm Free Antivirus+Firewall installed, but I made several steps, including the complete removal of the ZoneAlarm product, and I still have the same problem.
Here's what I see in the log:

Using the same client (32 bit version) in another pc of my lan which runs Windows XP and that had never ZoneAlarm installed on it, I have no problems.Also, using Shrew Soft Vpn Client 2.1.7 on the problematic pc I can connect to vpn without problems, so I am really stuck trying to understand what's wrong with Cisco Vpn Client.

I have setup the WLC to authenticate to a MS Server2008 NPS for a WPA2/AES SSID. The connection is successful, but client authentication fails for wrong EAP-type. I believe this indicates a Windows7 client issue. What is the required client setup to satisfy the MS NPS?
View 8 Replies View RelatedI have a problem when trying to access from a workstation on the internal network to an external FTP server using Explicit FTPS. After the server requires the client TLS Authentication the client inits TLS but the connection is closed by timeout.
I have disabled the FTP inspection on the firewall and I have opened some high ports from the Internet to the test workstation (ACL and NAT rules), but without results.
If I try to connect from a workstation to the FTP server using a direct Internet connection I can access the FTP server without problems, so I think the problem is in the ASA.

Is 3DES on ISAKMP considered to be secured for your average site (other options are AES/DES)? I'd imagine AES should be much stronger but what about DES, is that considered adequate or broken? Is there any proof of concept attack against 3DES on ISAKMP (or ISAKMP in general)?

I'm currently dealing with a weird problem on a Cisco RVS4000. I'm trying to connect to a IPSEC VPN Gateway (NETASQ) located on the LAN side of the RVS4000. I'm using Green bow vpn client on the WAN side of the RVS4000. Basically I'm trying to get through the RVS.My VPN config is OK because i tested it on the LAN side of the RVS.
The RVS is configured like this: NO VPN configured.
Block WAN Request :OFF
FIREWALL,IPS,DDOS are OFF
NAT forwarding on for UDP 500 and 4500 directed from the wan to the ip of the VPN gateway. Seems right because iv managed to do this with other routers (different brands) on another site.I've wire sharked my vpn client and i keep getting ICMP destination unreachable (PORT UNREACHABLE) after my ISAKMP launching packet.Can the RVS nat these ports ?

I upgraded my Cisco asa from 7.2 to 8.4 system image. Now the old style syntax isakmp policy is not working anymore and I am not able to write a isakmp policy to being used for remote access VPN.
on many examples on Cisco site I have seen that it is always used Cisco any connect client installed on ASA. this means that the old configuration compatible with Cisco vpn client IPSEC is no more usable ? or what kind of syntax I have to use to configure remote access VPN ? for example these commands are not working anymore.

Just looking at a new clients setup and they have a ISAKMP vpn to the old security company I am trying to remove...I am fairly new to cisco, I actually know how to setup the ISAKMP policies, acl's etc but never had to completely remove one before All I can find is Clear Commands which seem to just flush the config not actually delete any of the policy etc...Its not that urgent as all passwords are changed on the domain and the cisco, the usernames have been deleted as well.

We have a PIX firewall 515E running version 6.3(4) and there are few site to site VPN's installed on it. We want to find out the isakmp key for those VPN tunnels. On ASA, We can run the command "more system..." and it displays the key, but it seems it doesn't work on the PIX 515E.
View 1 Replies View RelatedI am currently experiencing an issue with an IPSEC Tunnel between a Cisco892-K9 (c890-universalk9-mz.124-22.YB.bin / Feature: advipservices) and a Checkpoint VSX R67.
After reloading the router the tunnel is stable, but afterwards we loose the connection to the LAN unexpectidly (max. time of the connexion is ~2h30).
In fact after a reload the first ISAKMP SA is well negotiated with conn-id 2001 and after a certain amout of time the connexion is lost always associated with this debug message =>
ISAKMP:(2001):error from epa_ikmp_gen_ipsec (QM_IDLE )
ISAKMP:(2001):Unable to generate IPsec key for 799280698!
ISAKMP:(2001):deleting SA reason "Death by retransmission P2" state (I) QM_IDLE (peer 194.X.X.X)
and so on ....
We supposed it was related to DPD messages so we deactivated the keepalive (no crypto isakp keepalive). We tried to play also with the ACL matching the crypto map (currently from local subnets to any), but still no luck.
When it is stable the ‘show crypto isakmp sa’ indicates a isakmp sa ‘QM_IDLE / ACTIVE), and when the problem occurs the active ISAKMP SA is deleted and recreated (in ACTIVE state) continuously : conn-id 2001, 2002, 2003, 2004 etc...…but still no access to the LAN.
My main question is to know if someone has already know the signification of the previous ISAKMP debug messages (along with the total debug message + crypto conf from the beginning of the problem) =>May it be a platform support (near 200 ipsec flow in use => most subnet to subnet flow, few subnet to host flows- 200 users on site) , compatiblity, crypto map acl …???
I am trying to set up a site to site VPN tunnel using GRE over IPSEC. Below is the configuration from both routers and debug output. I'm scratching my head on this one. I'm using two Cisco 7600 routers with SSC-400 SPA modules and 720 Supervisors. The IOS on R1 is 12.2 SXI2 and R2 has 12.2 SXI3.

My company recently failed a PCI scan because our router was returning 56bit des encryption for isakmp negotiation on an existing default isakmp policy. How do I remove this default isakmp policy. I am not running 12.4(15)T1 so the no crypto isakmp policy default does not work. Is there any way other than upgrading the IOS?
Is there any way to configure a maximum number of isakmp policies that an authenticating router will check? I have 2 configured higher priority ISAKMP policies. Maybe if there is a command to limit the number of isakmp policies the router checks, that would eliminate this default policy being matched?
I'm running a IPSec VPN between a 5520 ASA and a 2811 router. The ASA has a static IP and the router has a DHCP interface.The VPN seems to work fine once I get done clearing old SAs, but each new IPSEC SA creates a new ISAKMP SA on the router? There are multiple subnets that need to create multiple IPSEC SAs. Eventually I can clear the older ISAKMP SAs and get all the traffic on one ISAKMP SA, but until I clear older SAs, new associations won't form. Why the router (initiator) would keep creating new ISAKMP SAs and not use an established one? Using PSK, aggressive mode and no PFS. ASA has another dynamic crypto map with lower priority than this one. Using FQDN for identity on the router. ASA version 8.2(5) and IOS is 12.4(20)T1.
Must be something I'm not understanding. The ASA says no established SA and drops the new SA attempt until I clear older ISAKMP SAs out of the router. Interesting, the first few IPSec SAs form when the tunnel initially comes up. I assume the initial requests are getting cached and work immediately after the first ISAKMP SA forms, but subsequent IPSec SA attempts will fail. Once all subnets are talking with 1 ISAKMP SA, rekeys don't cause any problems. Since the router subnets have to instantiate the new IPSec SAs, this is a real pain to go through anytime the WAN/VPN fails.
I have been looking around and I can not find the " crypto isakmp policy " command on this Cisco Router 1941. I just wanted to setup a regular IPSEC Lan to Lan tunnel and surprise, the command is not there. Do I have the wrong IOS? I thought that a K9 image would do the trick. [code]
