ASA 55xx Defintion "Max IPSec Sessions.

Hello

I was responsible for the modernization of our current remote site VPN Tunnel project.

Rather than the collection of different configurations and protocols, I want to standardize it

so that all every site has an IPSec Tunnel from Site to Site.

I just need to clarify the definition of 'Site to site and remote access VPN maximum Sessions'

to help me decide in which ASA 5500 model I need.

(http://www.cisco.com/en/US/products/ps6120/prod_models_comparison.html)

We will need the connections for connections site to site 210,

each location has a static WAN IP address and a subnet.

So, I guess that the 5510, with its 250 ' maximum session limit "would be OK for our needs?

However, will be the "Maximum virtual interfaces (VLANS)", which is only 50, limit me - makes a VPN site-to site class tunnel as a virtual interface?

Or is there some other limiting factors that I need to consider?

Thanks a lot for your time,.

One site to the other tunnel do not catalogue as a virtual interface. So you shouldn't have a problem with this aspect.

I suggest that you get (or upgrade to) the Security Plus license - which increases many things including the number of virtual interfaces.

With 210 remote sites, I wonder what that the amount of traffic you are dealing with and if put through the 5510 could be a problem. If you look at the 5520, you get much more memory and a better/more battery power to provide more capacity.

  • How much max VPN session is my ASA

    This is my version to see the ASA5512 VPN

    "Other peers VPN: 250" means that I can use 250 IPSEC session? If I still use MAX 250 VPN Cisco AnyConnect Secure Mobility Client session?
    "Total peer VPN: 250" means that I can use 2 Anyconnect premium + 248 250 IPSEC or IPSEC session at the same time?

    "AnyConnect for Mobile: Disabled" means, I can't use AnyConnect Secure mobility Client (smartphone apps) connect to the ASA by AnyConnect SSL? Can I use AnyConnect secure mobility Client (smartphone apps) connect to the ASA by IPSEC?

    Hello!

    ASA5512 can contain up to 250 concurrent VPN of any type: IPsec Site to Site or IPsec Remote access or Anyconnect SSL VPN or IPsec IKEv2, or even without VPN client.

    This means you can use 2 Anyconnect premium + 248 IPSEC VPN from Site to Site. Or, for example, 200 simultaneous IPsec Site to Site VPN + 25 Client VPN (IPsec IKEv1) + 25 AnyConnect VPN (SSL or IPsec IKE v2). But not more than 250 and then at the same time.

    "AnyConnect for Mobile" is now obsolete. The license for Anyconnect schema was changed in early 2015. You can see the new pattern here:

    http://www.Cisco.com/c/dam/en/us/products/security/AnyConnect-og.PDF

    With the new scheme, if you need to connect mobile devices (iOS, Android and so on), using the Anyconnect client, you just need to have a license Anyconnect MORE for the necessary amount of users/devices. License AnyConnect more open along the lines in the output of the show version:

    AnyConnect Premium Peers : 250 perpetual
    AnyConnect for Mobile : Enabled perpetualAnyConnect for Cisco VPN Phone : Enabled perpetualAdvanced Endpoint Assessment : Enabled perpetual
    But, despite the exit "AnyConnect peers Premium: 250 perpetual", you will have the right to use no more then amount ordered... If you need advanced features, for example, Suite B cryptography or VPN without customer, you must order license Anyconnect Apex for amount of users/devices needed. For ASA5512, you need to order licenses Anyconnect more or Apex, but no more so for 250 users, because ASA5512 can't take no more then 250 simultaneous connections. If you want to use the Anyconnect client for mobile devices and you use IPsec IKEv2 for VPN, you will also need order licenses Anyconnect more or Apex. I hope this helps.
  • Information on the ASA 55xx

    Hello

    I'm starting to read about ASA 55xx in Cisco's Web site. But after a good read, I have a few questions...

    1. In Cisco Docs on ASA55xx, I see the "Maximum simultaneous AnyConnect or VPN sessions without client" and "Maximum simultaneous site-to-site and VPN IPsec IKEv1 sessions" (e.g. 750 times): well, the concurrent sessions maximux are 750 + 750 (anyconnect + site to site), so I have to add both types of sessions? Or what are the maximum (of each type) concurrent sessions in ASA5520?
    2. So, at this point, if I want 750 AnyConnect Session and site to site 750 Session what license should I buy? ASA5500-SSL-750? ASA-VPN-1000? or whatelse?
    3. so, what are the license "shared"? Where and when do I need to buy?

    Thanks in advance.

    Good bye

    The platform and required capabilities are allowed as indicated in the data sheet of the product:

    Up to 750 AnyConnect and/or peer clientless VPN can be supported by each Cisco ASA 5520 by installing an essential element or a Premium AnyConnect VPN license; 750 VPN IPsec peers are supported on the base platform. Resilience and capacity VPN can be increased by taking advantage of the Cisco ASA 5520 clustering integrated VPN and load balancing features. The Cisco ASA 5520 supports up to 10 devices in a cluster, offering a maximum of 7500 AnyConnect and/or VPN without client peers or 7500 counterparts of IPsec VPN by cluster.

    Resuming:

    The ASA 5520 750 capacity VPN site-to-site is in the base license / product (part number ASA5520-BUN-K9 or ASA5520-K8 whther in function, you are eleigible to buy encryption strong (-BUN - K9) version)

    The user AnyConnect required licenses depending on if you need Anyconnect Essentials or Premium. The Anyconnect data sheet describes the differences. Essentials is a license that allows customers to use the device at the same time up to 750. Premium (which cannot be loaded at the same time as Essentials) requires that the licenses to buy according to the prioritized by the user schema.

    Shared licenses are shared between ASAs in a cluster (2 or more units configured together).

    There is the concept of licenses in a failover cluster (2 units). It's automatic - i.e. the license numbers are additive and shared up to the capacity of the platform. ASA5500-SSL-750 part would be used in this configuration.

    There is also the concept of a Premium Shared Server anyconnect. In this system, the shared server allocates licenses in 50 blocks of unity to the ars of cluster members they need. ASA-VPN-1000 part number you mention is used in this kind of configuration.

  • Some IPSec sessions associated with tunnel stop working

    Hello

    Since I left an IPSec tunnel a router IOS to a Version running 3020 4.1.7.E there was a strange situation with a tunnel to a VPN Checkpoint 4.1: Tunnel get no problem but various IPSec sessions disappear with the only way to reset the being of "disconnection" (dixit the Sessions ' administer') whole tunnel can discuss again with interesting traffic. Example:

    -VPN 1 with 3 Sessions IPSec 172.1.30.x, 89.170.11.x and 192.168.3.x

    -Interesting traffic for each creates an IPsec session for each that can be viewed in the monitor or administer the Sessions

    -Suddenly, none of the specific time intervals the sessions 89.170.11.x and 192.168.3.x IPSec disappear from the sessions administer and cannot be used until the entire VPN tunnel is reset, then traffic does what it is supposed to and show all the necessary IPSec sessions.

    -It is not the case that the timeout of sessions has lost because they can be used in when it happens

    All the world faced a similar situation?

    I can't restrict logging to a counterpart to activate useful debugging - we have a number of LAN-to-LAN tunnels and quite a few customers. Can someone help me in this respect?

    I do not give the Checkpoint but can pass on ideas to those that do, if anyone has any.

    If I need to provide more information tell me what you need.

    Thanks for any help you can provide.

    IPSec driver successfully stopped

    Hello 3moloz123,

    Crypto ipsec transform-set esp-3des esp-md5-hmac TRANS_ESP_3DES_MD5

    Crypto ipsec transform-set transit mode TRANS_ESP_3DES_MD5

    Crypto ipsec transform-set esp-SHA-ESP-3DES-3des esp-sha-hmac

    1. the reason why the VPN remote access (RA) couldn't form with success before the passage of TRANS_ESP_3DES_MD5 to ESP_3DES_MD5 is the mode of transport is not supported for RA VPN.  You must use Tunnel mode for the processing of IPSec together we must maintain the IP header inside so that, once the package is decapsules and decrypted at the head of IPSec end we can transfer the package.

    In the newspapers, you can see this failure

    29 Dec 18:54: 26 [IKEv1]: Phase 2 failed: Mismatched types of class attributes Mode of Encapsulation: RRs would be: UDP Tunnel(NAT - T) Cfg had: UDP Transport

    Repeat x 4

    RRS of transformation all sent by the RA Client.  Cfg would be is that the dynamic encryption card supports.

    2. the isakmp policy change was unnecessary, the Phase 1 session came fine ISAKMP indicating worked.  Phase 2 begins only after a successful Phase 1 (session ISAKMP).

    After failing to build Phase 2 (child SA) we drop the ISAKMP Security Association since it is not used.

    I hope that answers your questions.

    Kind regards
    Craig

  • ASA 5505 VPN Client Ipsec config problems

  • ASA 8.6 - l2l IPsec tunnel established - not possible to ping

    Hello world

    I have a problem of configuration of the CISCO ASA 5512-x (IOS 8.6).

    The IPsec tunnel is created between ASA and an another non-CISCO router (hereinafter "router"). I can send packets ping from router to ASA, but ASA is NOT able to meet these demands. Sending requests of ASA is also NOT possible.

    I'm trying to interconnect with the network 192.168.2.0/24 (CISCO, interface DMZ) premises and 192.168.3.0/24 (router).

    The CISCO ASA has a static public IP address. The router has a dynamic IP address, so I use the dynamic-map option...

    Do you have an idea that I am wrong? Probably some bad NAT/ACL I suppose, but I could always find something only for 8.4 iOS and not 8.6... Perhaps and no doubt I already missed the configuration with the unwanted controls, but I've tried various things...

    Please, if you have an idea, let me know! Thank you very much!

    Hello

    I've never used "global" option in ACL, but it looks to be the origin of the problem. Cisco doc.

    "The global access rules are defined as a special ACL that is processed for each interface on the device for incoming traffic in the interface. Thus, although the ACL is configured once on the device, it acts as an ACL defined for Management In secondary interface-specific. (Global rules are always in the direction of In, never Out Management). "

    You ACL: access-list extended dmz_acl to any any icmp echo

    For example, when you launch the ASA, there is an echo response from the router on the external interface--> global can block.

    Then to initiate router, the ASA Launches echo-reply being blocked again.

    Try to add permit-response to echo as well.

    In addition, you can use both "inspect icmp" in world politics than the ACL.

    If none does not work, you can run another t-shoot with control packet - trace on SAA.

  • Easy remote VPN - IPsec Session count

    I have recently updated our ASA5510 head to our datacenter to 8.2.1 to 8.4.5. The ASD has been also improved 6.2.1 to 7.1. (1) 52. Under the old code, a connected remote ASA5505 via remote VPN easy showed 1 IPsec tunnel. However, after the upgrade, it shows 42 sessions. It seems to me that each split tunnel network defined in the easy VPN profile is being counted as a tunnel. Someone has seen this, or is - it possible that I may have something misconfigured now that the code is upgraded? Thank you.

    Dave

    No, IMHO, it's a display error in ASDM for 7.1.

    Return to ASDM 6.4.9 and it should be 1 tunnel.

    I am currently troubleshooting an ipsec VPN l2l between

    2 cisco 871W to SSG - 140

    In both scenarios the tunnel is well established and the traffic is in the tunnel, but nothing comes out. Of all the encap, but no decap

    Looks a routing problem, but we cannot find anything on the two sites.

    So maybe I m running in a (known) problem between equipment cisco VPN and SSG-140?

    I've searched the forum, but can not find any idea on this subject.

    If anyone has an idea the most welcome.

    What is a proxy-id problem? Cause they set up stuff like 10.1.1.0/24 and I configure 10.1.1.0 0.0.0.255

    Thanks in advance!

    Tom, I have not seen the downloaded configs or poster. I would focus on the asa as it's easier to troubleshoot. You can use the ease of packet trace to verify that the syn is sent through the encrypted and external interface. Also gives you the ability to capture. Of course, the problem is that the traffic is encrypted. A syn packet is small and hard to distinguish. Try to send a ping from 10 to 1000 pkt size and see if you can locate in the capture (ipsec will add about 80 bytes). You will need to do a quiet moment to make it easier. Assuming that you can identify the packages, you can repeat the capture and ask someone to do the same thing at the remote end. Also, try to do the ping from the remote device and see if you can capture packets. My guess is that there is something wrong at the other end or a firewall drop packets (ip prot 50) esp. If you want to send the config, display, capture of the [email protected] / * / I can take a look. Matthew

  • ASA 5505 VPN to IPSec website DOES NOT CONNECT

    I spent 2 days already to try to get 2 ASA 5505 to connect by using an IPSec vpn tunnel. I can't understand what im doing wrong, I'm using 192.168.97.0 and 192.168.100.0 as my internal networks that I am trying to connect via a link directly connected on the outside with 50.1.1.1 and 50.1.1.2 interfaces such as addresses (all 24). I also tried with and without active NAT. Here is for both of the ASA configs, the vpn config was conducted by the ASDM, but I also tried the approach of the command-line without success. I followed various guides to the letter online, starting with an empty config and factory default. I also tried the IOS 8.4.

  • Cisco ASA 55xx. Backup/restore an external certificate signed with ASDM

    I have a Cisco ASA 5510, which is used for our VPN. It has an externally signed certs from Digicert. I replace the 5510 with a Cisco 5545 and wondered with ASDM can I save the cert of the 5510 and give the 5545. Or should I get an another reissued certs from Digicert and install from scratch. Is there something to look out for that set games with public/private keys, etc. Please let me know.

    You guessed it right, Edwin

    As long as you want just to maintain the certificate configuration, it is what you need to.
    Make sure that you install the root and root under new ASA certificate as well as one can extract this PKCS12 certificate.

  • ASA - 5540 used for IPSec VPN only - I can do away with Nat 0?

    I'll use an ASA 5540 as our head of VPN endpoint only - and not as a firewall.

    Also, we have a class for our company internal address space routable B address, so we don't need NAT. I would like to disable the function NAT 0 if I can so I always add NAT 0 to ensure that the 5540 does not NAT.

    Y at - it an easy way to disable the need using NAT 0?

    Are there any of the draw to do that?

    You can disable the use of nat 0 disabling the nat control.

    To achieve this, go to the global configuration mode and use this command:

    no nat control

    To check whether you have it turned on, you can check it with:

    SH run nat-control

    See you soon!

  • How to match tunnel-group with auth ASA 8.2 and IPSec VPN Client using digital certificates with Microsoft CA

    Hello

    I set up a lab for RA VPN with a version of the ASA5510 8.2 and VPN Client 5 software using digital certificates with Microsoft CA on a Windows 2003 server. I did the configuration based on this document from Cisco's Web site:

    http://www.Cisco.com/en/us/partner/products/ps6120/products_configuration_example09186a0080930f21.shtml

    Now, the vpn works fine, but now I need to configure a tunnel-different groups so I can provide different services to different users. The problem I have now is that I don't know how to set it up for the certificate is the name of tunnel-group. If I do an ASA debug crypto isakmp I get this error message:

    % ASA-713906 7: IP = 165.98.139.12, trying to find the group through OR...
    % 3 ASA-713020: IP = 165.98.139.12, no group found by matching well payload ID: unknown
    % ASA-713906 7: IP = 165.98.139.12, trying to find the group via IKE ID...
    % 3 ASA-713020: IP = 165.98.139.12, no group found by matching well payload ID: unknown
    % ASA-713906 7: IP = 165.98.139.12, trying to find the group via IP ADDR...
    % ASA-713906 7: IP = 165.98.139.12, trying to find the group using default group...
    % ASA-713906 7: IP = 165.98.139.12, connection landed on tunnel_group DefaultRAGroup

    So, basically, when using certificates I connect always VPN RA only with the group default DefaultRAGroup. Do I have to use a model of different web registration for application for a certificate instead of the user model? How can I determine the OU on the user certificate so that match tunnel-group?

    Please help me!

    Kind regards

    Fernando Aguirre

    You can use the group certificate mapping feature to map to a specific group.

    This is the configuration for your reference guide:

    http://www.Cisco.com/en/us/partner/docs/security/ASA/asa82/configuration/guide/IKE.html#wp1053978

    And here is the command for "map of crypto ca certificate": reference

    http://www.Cisco.com/en/us/docs/security/ASA/asa80/command/reference/C5.html#wp2186685

    Hope that helps.

  • Cisco ASA 55XX Transparent mode through a VLAN

    Hello team Cisco Forum!

    In a scenario where the Cisco ASA is in Transparent mode, it is possible to route the traffic of L2 other VLAN different that the VLAN native IP for the firewall management lies?

    Switches on the outside and the inside of the interfaces of the SAA are in trunk mode, and I'm moving ttraffic VLAN L2 from inside to outside and vice versa by using filters on switches (switchport trunk allowed vlan).

    Thank you in advanced for your support and comments!

    Yes it is possible, but you will be limited to 8 VLAN, or more precisely, 8 interfaces BVI so it's not a scalable solution.  The problem is that you will need to have different VLANS to the same subnet at both ends of the SAA.

    To clarify this point, lets say, you use the interface Gig0/1 and Gig0/2.  Gig0/1, you would set up subinterfaces with VLAN 2, 3 and 4.  Now, if you try to configure the same VLAN on Gig0/2, you will get an error saying something like this VLAN is already configured on another interface. I don't remember the exact error.

    So to get this working, you need to configure Gig0/2 with subinterfaces for VLAN... lets say... 5, 6 and 7.  you would then associate VLAN 2 and 5 with BVI 1, VLAN 3 and 6 with 2 Virgin Islands British and VLAN 4 and 7 with 3 British Virgin Islands.  Each interface BVI would have its own IP address for the subnet on which is to be filled in all of the ASA.

    Hello

    What do you mean by limit? The number of IPSEC sessions is limited to 250, if I remember correctly.

    To limit access to internal resources, there is not.

    These users complain using the same IPSEC vpn as others? Is that your exemption of crypto and nat that allows all internal resources?
