  Duyen

  Hello Duyen,

  I think I've narrowed the issue. When remote access VPN using RADIUS authentication we must keep in mind that authentication and authorization are included on the same package.

  Depending on your configuration, the ACS is defined as a server RADIUS (Gserver Protocol radius aaa server) and becomes the VPN Tunnel authenticated and 'authorized' on this server group:

  authentication-server-group LOCAL Gserver

  authorization-server-group Gserver

  As noted above, the RADIUS of request/response includes authentication and authorization on the same package. This seems to be a problem of incorrect configuration that we should not set up the 'permission' in the Tunnel of the group.

  Please remove the authorization under the Tunnel of Group:

  No authorization-server-group Gserver

  Please test the connection again and check the logs of the ACS. At this point there are only sucessful newspaper reported on the side of the ACS.

  Is 'Permission-server-group' LDAP permission when authenticating to a LDAP server so to retrieve the attributes of permission on the server. RAY doesn't have the command as explained above.

  I hope this helps.

  Kind regards.

• iPad VPN from Cisco ASA 5520

  Hello

  I'm trying to get my ipad to VPN to our Cisco ASA5520.

  I think I have all the correct settings on both ends (I am able to vpn to the asa using a cisco 871 as the remote client).

  I think that for some reason the client vpn on ipad is not even make the asa. My question is: How can I monitor the ASA logs to see if the same connection attempt and eventually find the failure?

  Thank you

  M

  try: -.

  Debug crypto ISAKMP

  Debug crypto ipsec

  Vpn-sessiondb SH remote control (to see if the client is connected)

  I have configured ipad for remote vpn client, the user could connect to the 5520 but why that I had to use the ip addresses to access, but I couldn't use internal dns names. try to understand that at this moment.

• IPSec VPN between Cisco ASA and Fortigate1000

  Hello

  I find a useful document on how to create a tunnel VPN IPSec with ASA 5510 firewall Fortigate 1000...

  the configuration of the coast FG is done without any problem, BUT the document (. doc FG) said I must configure the ASA with a GRE interface and assign an internal IP address in order to communicate with the FG...

  The question is: How do I configure the interface on the SAA ACCORD?

  Thanks in advance, Experts...

  Kind regards...

  ASA firewall does not support the interface/GRE GRE tunnel.

  If you need to have GRE configured, you will need to complete the GRE tunnel on router IOS.

  If you want to configure just pure tunnel VPN IPSec (lan-to-lan), here is an example of configuration on the side of the ASA:

• The traffic load between the power of Cisco ASA and FireSight Management Center fire

  Hi all

  I have a stupid question to ask.

  Can I know what is the traffic load and the e/s flow between firepower Cisco ASA and FireSight Management Center?

  Currently working on a project, client require such information to adapt to their network. Tried to find in the document from Cisco, but no luck.

  Maybe you all have no idea to provide.

  It varies depending on the number of events reported from the module to the CSP. No event = only health controls and policy changes are exchanged. 10,000 events per second = much more traffic.

  Generally it is not a heavy load, however.

• Configure to integrate Cisco ASA and JOINT

  Hello

  We have Cisco ASA and JOINT, need assistance on the integration of the same thing; Please email me so that I'll share the details of the architecture.

  Thank you best regards &,.

  REDA

  Hi reda,.

  If I correctly your diagram, you do not want to send any traffic from the external switch to the JOINT with a SPAN port and all traffic from your DMZ interfaces with another.

  Is this correct?

  If so, can you tell me why you want to inspect the traffic before it goes through the firewall? As I said in my original answer, we generally advise putting IP addresses after the firewall.

  Not to mention that in your case, I guess that some traffic will be inspected twice so you will need to assign a different virtual sensors to each JOINT internal interfaces to ensure that the same instance does not see the traffic of several times.

  Kind regards

  Hi, quick question.  We have a CISCO 2921/K9, who has all of the features securityk9 (reflects Permanent under show version)

  I thought including SSL VPN, but make a "show license all" it does not reflect that:

  J:: feature 4: SSL_VPN Version: 1.0

  securityK9 does not include the SSL VPN license. This just activate the security features on the ISRG2, and you would need this license to run VPN SSL, and the SSL VPN itself license.

  Mattew, obvious lack of education is the rule exempt from nat for your tunnel, your access list pixtosw is similar on this example, I assume that you have gone through this link, if it does not see the configs on both sides.

  Add the statement of rule sheep in asa and try again.

• Cisco ASA and dynamic VPN L2L Fortigate configuration

  I met a problem recently with an ASA 5510 (7.0) and a bunch of Fortigate 50 (3.0 MR7). The ASA is the hub and Fortigates are rays with a dynamic public IP.

  I followed this document on the site Web of Cisco (http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a00805733df.shtml) to set up my ASA and the parameters passed to my counterparts to set up their Fortigates.

  However, the ASA journal reveals that attemtps Fortigate connection always tried with DefaultRAGroup before falling back to DefaultL2LGroup and finally died. Experience with putting in place a dynamic VPN between Cisco and Fortigate someone? Which could not fail at each end? Here's a typical piece of error log ASA. The ASA is currently having a static VPN tunnel and a site-2-client VPN in two groups by default.

  Yes, sounds about right. He will try to match with the DefaultRAGroup first, and when you know that it's a dynamic IPSec in LAN-to-LAN, it will be

  then back to the DefaultL2LGroup, because he doesn't know if the VPN Client or L2L again when he is contacted fist as they are connecting from dynamic IP peer.

  You must ensure that your L2L tunnel-group by default has been configured with the corresponding pre-shared key.

  Assuming that you have configured the dynamic map and assign to the card encryption.

  Here is an example of configuration where ASA has a static and peripheral ip address pair has dynamic IP:

  Can someone tell me what I am doing wrong or what access list I'm missing?

  I have two Cisco ASA 5510 firewall with a similar setup configuration and the AnyConnect SSL VPN works great.

  Hi Matt,

  You are probably landing on the tunnel-group by default - you will need to indicate which group to connect to the client. This can be done in different ways - I see that you already have a defined group aliases, but to be able to use that you must configure:

• Order SSL VPN with Cisco Cloud Web Security

  We have implemented Cisco Cloud Web Security with the connector of the ASA and transfer all traffic port 80 and 443 to the Tower of the CCW. We have enabled HTTPS inspection, and I was wondering if there was anything, we can add in the configuration that would allow us to control (allow/block) SSL VPN?

  #Clientless SSL VPN is not supported with Cloud Security Web; don't forget to exempt all SSL VPN traffic without client service ASA for Cloud Web Security Strategy.

• IKE Dead Peer Detection between Cisco ASA and Cisco PIX

  I have a network environment in Star with about 30 offices of satellite remote using VPN Site to Site connectivity.  The majority of remote satellite offices have the features of Cisco PIX 501 running PIX Version 6.3.  The hub office runs a version 8.2 (1) Cisco ASA.

  I configured Dead Peer Detection on the Cisco ASA device at the office hub with the default settings of the following-

  Confidence interval - 10 seconds

  Retry interval - 2 seconds

  I think I'm right assuming that raises are limited to 3 before the tunnel is completely demolished.  Basically, the problem that I am facing is with several remote satellite offices.  What seems to be the case, the tunnel between the remote offices and the hub is demolished (probably because of the length of IKE, always 86400 seconds) and the tunnel then fails to renegotiate unless traffic is physically forced from the hub office.  The tunnel NOT to renegotiate after satellite office, ONLY the end of the hub; so that means sending traffic to the satellite when the VPN tunnel is out of service, not to renegotiate the tunnel.  The Hub office is a colo and therefore traffic rarely comes to that end, the tunnel remains so down until manual intervention occurs and the ICMP traffic is forced into the tunnel.

  Should the KeepAlive and retry interval settings corresponds to both ends, for example if the two devices be configured for DPD?

  What are the potential pitfalls to the extension of the life of IKE, and this will help or even hinder the problem?

  Thank you in advance for helping out with this.

  Hi Nicolas,.

  I think that the two DPD settings must match on both ends, if these do not match then problems like yours might arise which seems to happen here, is that one end shows a tunnel down, but the other end may not detect it down, we could have to watch debugs, or record two ends to see if this is the case , setting in the meantime ike DPD for same timers could hetlp on.

  In regard to the increase in the life expectancy of IKE, well you just need to be aware that this could allow keys to be discovered since these are not renegotiated unless the tunnel is down on the level of IKE. Other than that I don't see why this would affect you.

• NAT before going on a VPN Tunnel Cisco ASA or SA520

  I have a friend who asked me to try to help.  We are established VPN site to site with a customer.  Our camp is a Cisco sa520 and side there is a control point. The tunnel is up, we checked the phase 1 and 2 are good. The question is through the tunnel to traffic, our LAN ip address are private addresses 10.10.1.0/24 but the client says must have a public IP address for our local network in order to access that server on local network there.  So, in all forums, I see that you cannot NAT before crossing the VPN tunnel, but our problem is that our site has only 6 assigned IP addresses and the comcast router, on the side of the firewall SA520 WAN.  So we were wondering was there a way we can use the WAN on the SA520 interface or use another available 6 who were assigned to the NAT traffic and passes through the tunnel.  That sounds confusing to you?  Sorry, but it's rarely have I a customer say that I must have a public IP address on my side of the LAN.  Now, I say this is a SA520 firewall, but if it is not possible to do with who he is a way were able with an ASA5505?

  Help or direction would be very useful.

  Hello

  I guess I could quickly write a basic configuration. Can't be sure I remember all correctly. But should be the biggest part of it.

  Some of the course settings may be different depending on the type of VPN L2L connection settings, you have chosen.

  Naturally, there are also a lot of the basic configuration which is not mentioned below.

  For example

  • Configurations management and AAA
  • DHCP for LAN
  • Logging
  • Interface "nonstop."
  • etc.

  Information for parameters below

  • x.x.x.x = ASA 'outside' of the public IP interface
  • y.y.y.y = ASA "outside" network mask
  • z.z.z.z = ASA "outside" IP address of the default gateway
  • a.a.a.a = the address of the remote site VPN L2L network
  • b.b.b.b = mask of network to the remote site VPN L2L
  • c.c.c.c = IP address of the public peer device VPN VPN L2L remote site
  • PSK = The Pre Shared Key to connect VPN L2L

• Cisco VPN 3060 - Cisco ASA conversion

  We are about to embark on the passage of all extensions L2L and network (Cisco ASA 5505 s) of the Cisco VPN 3060 concentrator to a Cisco ASA 5520.

  We bsemblable woul to see if there is a simple method to do this as a converter?  Also, there are lessons learned?  We run 8.4.3 so that we know that the NAT configuration has differed.  The 3060 configuration can be changed in anyway for help in configuring the ASA?

  Thank you
