• role of the crypto map sequence number

  I'm setting up IPSEC in four sites in a manner completely mesh. The problem I have is one of the sites is our main hub and everything works on a class B network. Creating ACL to get from one place to another is relatively simple, but getting a site on the main hub is another story, because other sites are all the subnets in the class B address, I have to remove these subnets of a class B and at the same time to encrypt the rest of the class B address. Subnets of the smaller sites are for most of the 24 and 25. I was wondering if the sequence # in the card order crypto could play a role for me. If I set the priority on small sites and put the lower on the map pointing to the main pole encryption could I get away with something like this:

  licence (local subnet) 0.0.0.255 x.x.x.x where x.x.x.x (category B) 0.0.255.255

  Thanks in advance for taking the time.

  Mario... that's exactly how it works for the two ISAKMP Crypto map policies and policy. It will look at the lowest number (like attentive) so if you do your remote sites all a higher priority (lower number), then you should be fine with respect to the central site.

  I saw her a couple of times and to be honest have never taken down to an exact cause, although in this case it looks like almost to the point of control request an IP address which is weird. Try the following:

  1. Add "card crypto secure1_in client configuration address to initiate" and see what it does.

  2. try 12.2 (8) code T5 with it, I had a previous user running 12.2 (11) T and we got the same error messages, returning to this level of code it is resolved.

• Dynamic Crypto map & Defaultl2lGroup

  Dear all,

  How Defaultl2lGroups & dynamic crypto of the cards can be configured in an asa.

  Why I need?

  All our stores because asa 5505 (with dynamic ip addresses) are connected to the network head asa 5550 via dynamic vpn and headboard has 2 ISPS.

  In fact, we have two lease lines a primary and another backup. Surprisingly, we have only a single subnet on the inside. Now that the main link BW is fully occupied. I want to use the help link too. I wonder if I can have several dynamic cryptographic cards & several groups default tunnel. While I can define servers in one vlan and users in other VLANs. and with two dynamic crypto & default tunnel grps I think passing a subnet (part of the 1st dynamic default crypto & 1 tunelgrp) and second subnet on the other link (2nd dynamic crypo & 2nd tunel default grp). This way the user vpn and internet traffic wil go through 1 link and vpn servers and internet traffic will pass through second link as both the subnet vpn will have another link as backup to each other.

  Please provide us with the possibilities.

  Please share your ideas.

  Help, please.

  Thanks in advance,

• supported vs IPSec VRF taking crypto maps for several tunnels

  Hi all!

  I came to know that we can use the same public ip address for the creation of several tunnels to different websites using crypto-cards featuring many lines each representing a reference to a particular tunnel and using vrf aware IPsec, but I would like to know what are the differences / advantages / cautions.

  Thanks for your time

  Murali.

  Murali

  That I understand the feature essentially allows you to have multiple IPSEC tunnels and traffic in the tunnel that is to say. source and destination IP of the high-end devices can be in different VRF.

  So it works mainly with the MPLS VPN IE. If you had several MPLS VPN each with their own VRF you can then run ISPEC tunnels on the MPLS network and when packets are received, they are automatically in the correct VRF.

  You could not do that normal crypto cards IE. You can cancel again several IPSEC tunnels on a public IP address but then everything would be traffic in the same global routing table.

  If the benefit is basically the same that you get with any VRF installation IE. logical separation of traffic on a single device.

  Can't really say much about the warnings as I've never used it but there are some restrictions.

  See this link for more details-

• ASA dynamic Crypto map

  I was looking at this example and did not have a clear explanation about the use of the

  tunnel-group DefaultL2LGroup

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080b3d511.shtml

  Why is the pre-shared-key * different pre-shared key talks about cisco123 ? What is a wild card to accept any

  identification key by spoke them? Can it be set or is set as it is? I don't see the advantage if it's 'accept all '.

  Thank you

  Pete

  Pete,

  "*" is how ASA will display a key, it is hidden when you list the running configuration.

  bsns-asa5505-19#  conf t
  bsns-asa5505-19(config)# tunnel-group BERN ipsec-attributes
  bsns-asa5505-19(config-tunnel-ipsec)# ikev1 pre-shared-key 1234556778
  bsns-asa5505-19(config-tunnel-ipsec)# sh run tunnel-group BERN ipsec-attri
  tunnel-group BERN type remote-access
  tunnel-group BERN ipsec-attributes
  ikev1 pre-shared-key *****
  

  There is no 'accept all' in IKE given that this key will be used to protect and decode identities of IKE.

  Also, take a look in the tunnel-group mapping.

  At a glance by default, tunnel groups are used as a last ditch effort in the match. That is, they will receive most of the peers with IPs dynamic (or unspecified).

• Encryption: "Apply crypto map interface.

  East - the best forum to discuss encryption?

  I want to implement a single aes encryption between an ISDN Bri1/0 port on a 2611xm and a 2811.

  I want to encrypt everything except telnet on the ISDN link between these routers. I want to telent between routers just in case the encryption locks himself. This is my requirement of customers.

  Question #1: Should I contact the card encryption the Ethernet port (as I have seen in many examples) or on the ISDN connection?

  Question #2: If I ask the encryption card to the ISDN connection, should I do the encryption the BRI port card or the dialer?

  Question #3: Assuming that both routers and all segments use the 10.0.0.0 network and are not connected to what anyone else, the following access list would work?

  access list 110

  deny ip any eq telnet

  allow an ip

  Mark

  Hi Mark,

  Apply the card encryption to your outgoing interface (Dialer)

  You probably will lock the router by putting

  an ip address allowed any one in your crypto access list

  you have probably even to add telnet deny entry in your access list if you are ready to open your session to the router

  I suggest you

  extended to remote IP access list

  deny ip any eq telnet

  Is it possible on ASA to bring up the tunnel vpn site to site static crypto map without generating interesting traffic? I want to reverse route injection generate road dynamic until traffic begins to flow.

  Roman,

  Unless something chnaged recently RRI inserts routes without present SAs, meaning that they are static (in contrast to current default behavior on IOS 12.4 (9) T-I_think leave).

  But to answer the question, in more recent versions, you can bring up the tunnel using packet - trace CLI.

• Card crypto on Interface Ethernet

  Hi all

  I don't have that much experience but with VPN configs, so maybe this question will seem a bit silly. I have a Cisco 831 that I use to connect via VPN to a remote site. Everything works fine.

  Then I wanted to add a second tunnel to another location. I did all the configs needed, applied card encryption on ethernet external and everything was fine, I could connect. But then I noticed that the new encryption card has actually replaced the existing one. Of course, the first VPN was no longer works.

  Is this a limitation of the 831? Or y at - it another way to configure them so I can use the two (or even more than two) at the same time? Do I need another Cisco router if I want more than a tunnel?

  Any help is appreciated.

  Thank you

  Stefan

  This isn't a limitation of the router. But by design,.

  only one crypto map set can be assigned to an interface. If multiple crypto map entries have the same name but a different seq - num map, they are considered as part of the same set, and all apply to the interface.

  So what you need to do is create crypto-map with the same name for slot 2, but give a different sequence number. Apply this encryption card to the interface and it will work. From the seq - num lowest crypto card is considered to be the highest priority, and will be evaluated first.

  CYM

  You need not to N isakmp policy to support associations N IKE. You can use one for all remote locations. You could live with isakmp policy 10 and use the Group Diffie-Hellman 1 2 or 5 (do not need all three). Just make sure that there are individual cryptographic cards for each site (unless your doing dynamic VPN).

  Also you do not need separate transform-sets because you use the same encryption methods in all three sets of transformation that you have defined.

  If you do not want to change the configs that above, all you have to do is to create a key isakmp, as well as a new instance of crypto 40 for the 4th remote site map.

• Cisco asa 9.1: crypto acl - order, order of operations,.

  Hello

  Let's say we have the following configuration

  VPN1 list extended access permitted ip 192.168.1.0 255.255.255.0 10.0.0.0 255.0.0.0

  card crypto mymap 10 correspondence address vpn1

  access-list extended 192.168.1.0 ip VPN2 allow 255.255.255.0 10.1.1.0 255.255.255.0

  mymap 20 match address vpn2 crypto card

  card crypto mymap 20 peers set y.y.y.y

  In the above example, what happens if you intend to send a packet to a host on the 10.1.1.x and her counterpart that x.x.x.x is down (not SA).

  If Asa will verify that the SA is down or away he starts the process of the next crypto access list according to the sequence number of crypto card? or simply drag the package?

  If Asa trial next crypto map entry/crypto acl and that if no matching ACL? Packets are sent as clear text?

  Thank you explantion

  Hi Peter,.

  This would work if the first tunnel is down and there is not SA for her.

  However, it is not recommended to overlap crypto ACL.

• Multiple Crypto cards on a single Interface of ASA

  Hello

  I work with a TAC support engineer, and while troubleshooting it suggests to assign two different cryptographic cards on a single interface.

  It is technically possible to have multiple Crypto maps on a single Interface ASA?

  PS: I know have several sequences in a single encryption card would work, but it is a case that I must address multiple Crypto maps on a single ASA.

  Hi Ali,

  The rule is by interface, a single card encryption is supported. You cannot assign more than one encryption on a single interface card.

  Documentation: -.
  "You can only assign a single encryption card defined on an interface. If multiple crypto map entries with the same name of card but a sequence number different, they are part of the same series and are applied to the interface. ASA first assesses the entry card crypto with sequence number low. »

  When the tunnels are completed on the router, which is the area free, by default, all traffic is allowed, if you want to restrict access, you must create a free zone and add a pair of WAN area to auto.
