• 2 crypto maps to the external interface? Possible?

  Hi, I have a little problem with a PIX 515 UR on FOS 6.3 (1).

  What I'm trying to do is to run 2 VPN site to site to him. The thing is: although I can get two separate crypt cards into the config, its only the more recent which is active when I do a ' sh crypto his '.

  Anyone have any ideas?

  TIA-

  Gary

  I do multiple like this:

  I have the main Board, applied externally:

  toXXXX interface card crypto outside

  Then, I build maps more screaming like ACL if:

  toXXXX 20 ipsec-isakmp crypto map

  card crypto toXXXX 20 match address no_nat (name of the ACL)

  card crypto toXXXX 20 peers set x.x.x.x

  toXXXX 20 transform-set mytrans crypto card

  life safety association set card crypto toXXXX 20 seconds 3600 4608000 kilobytes

  toXXXX 40 ipsec-isakmp crypto map

  card crypto toXXXX 40 correspondence address toACME (name of the ACL)

  card crypto toXXXX 40 peers set x.x.x.x

  toXXXX 40 transform-set mytrans crypto card

• 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.

• Priority crypto map

  Hi all

  I try to have several VPN site-to-site hooked to my Interface Outside one.

  I understand that I may have a crpypto card assigned to the interface.

  If I want to for example, one of virtual private networks to require PFS but either not to do it-just set a different priority under the Crypto map? Map crypro entries get transformed top to bottom until a match is found?

  for example

  CMAP 10 ipsec-isakmp crypto card
  defined peer x.x.x.x
  game of transformation-TSET
  match address ACL1

  Crypto map CMAP 20 ipsec-isakmp
  defined peer y.y.y.y
  game of transformation-TSET
  match address ACL2
  set the pfs Group 2

  Thank you

  You're right, the encryption card is dealt top-down. So if your traffic is ACL2 (and not ACL1!), then all settings configured under sequence CMAP 20 are relevant in this regard.

  router. The static map seems to work by itself. What I am doing wrong?

  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.

• Area-based-Firewall: card crypto / tunnel interface / area?

  Hello

  We use a router CISCO1921-SEC. On the side "WAN", we have 1 public IP assigned by DHCP address.

  At present, we use the WAN Interface with a crypto-map as endpoint of some IPSec connections. We have created a zone - fire-with area "WAN" and "LAN". In this configuration, all IPSec parameters are on a single Interface - connection to the 'LAN' box can be managed through rulesets. What about the connections between IPSec connections and the area "self."

  We would like to finish each IPSec connection in a separate area. Is this a good idea?

  How can this be configured?

  Each of them on a "inetface tunnel" with binding "tunnel source...". » ?

  Please give us a clue... Thank you!!

  Message geändert durch NISITNETC

  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.

• 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

  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.

  Kind regards

• 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,

  Kind regards

  I also do a show run all | I have the interface Vlan 2 and there is no config hidden for this too.  Does not support this version of IOS.

  I suspect it's because your other switches in the stack are not 3750-12s switch?

  3750-12s switch running the model of aggregation by default but all other 3750 s cannot run office model.

  Then on the master can try this-

• ASA5505 inscription on SSL cert error when applied to the interface?

  Created a CSR, gets the certificate files, the downloaded ASA505.   Three certificates in the CA certificates; the one in the certificate of identification.  Everything seems all just wonderful.  "Now use the SSL certs: in trying to associate the certificate with the Interface in the SSL settings section, we get an error"

  The cert will appear in the drop-down selection, why the error?  How do I delete it?

  Hi Stewart Buswell,

  I have seen this problem when starting the CSR request through the CLI by using the configuration of the terminal of registration and then going to the ASDM and adding the identity certificate without using the command crypto ca enroll through the CLI.

  In this case, if you use the CLI/ASDM you can follow this guide:

  http://www.Cisco.com/c/en/us/support/docs/security/ASA-5500-x-series-NEX...

  And the way to solve this problem will be generation a new CSR on the ASDM using the same key pair and install the certificate on this trustpoint. After you apply the cert to the ssl, you can remove the old one which was not.

  Hope this info helps!

• ACL IPSEC - CRYPTO vs Interface

  Hello

  Where an IOS device is connected to a PIX 6.3, with a VPN IPSec site to site with ipsec connection allowed sysopt

  Thinking that it would be simpler to apply the required ACL, I created the ACL crypto to the entire subnet with the thought I would create ACL interface for nailing to specific hosts inside the subnet.  I see now that I need to disable the connection of sysopt permit-ipsec for the ACL interface to apply.

  1. is it more common for crypto ACL to be more host specific vs specific subnet and the necessary ACL ONLY (with the active sysopt)? I have a true Swiss cheese of the armies on either side of the vpn that need access and I didn't want to maintain such a complicated in meaning OPPOSITE ACL.

  2 or it is more common for both - crypto ACL (allow a simpler ACL) then apply ACL interface?

  3. I see the issue with the realization of the interface & crypto ACL, there is more that can get sent THEN denied to the remote interface, or even blocked traffic on the local side.  If the ACL interface should be used, what is the best practice here?

  4. I see the interface that acl work when sysopt allowed ipsec connection is enabled, but only on outbound traffic. Is it because traffic has not struck the crypto ACL again?

  Any pointers in the right direction would be appreciated.

  Thank you

  Dan Foxley

  Dan

  Much depends on whether the VPN device also acts as a firewall. If this isn't ie. Once the traffic has been decrypted, it is then passed on the firewall then allowed sysopt of active ipsec connection is a logical choice.

  In response to your questions, speak from my personal experience-

  (1) crypto ACL tend to be more subnet than host-based, but it depends on your specific needs.

  (2) Yes, in general the crypto acl is more general, the acl interface is where you attach.

  (3) don't know, I followed. If you want to limit this subnet traffic is sent through the tunnel then you would with an acl interface but on a different interface IE. the interface more near the source of the traffic.

  (4) it is to do with the order of treatment IE. which is done first. Not really used an acl outgoing on the same interface as endpoint vpn but I suspect you're right.

  Note that you do not need to apply the acl on the actual interface the VPN ends, at least with the code v7.x and beyond. You can terminate the VPN on the external interface, and then use an outbound acl on the interface that is sent unencrypted traffic. Yes, that means he has to go through the firewall, but it can make the management of your ACLs easier.

• 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-

  http://www.Cisco.com/c/en/us/TD/docs/iOS-XML/iOS/sec_conn_ikevpn/configuration/XE-3s/asr1000/sec-IKE-for-IPSec-VPNs-XE-3s-asr1000-book/sec-VRF-aware-IPSec.html

• 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).

  1: try to add the following command in your router.

  Panel MultiLink virtual-model 1

  2: set 'crypt map rtp' command in virtual model 1 void-configuation.

  3: remove 'crypt map rtp' command of all the interface configuration and closure of the serial interface.

  4: highly recommended to remove the following command from each serial interface.

  Check IP unicast reverse path

  5: If still does not work, apply new 'crypt card rtp"command in all interfaces of Seraglio under configuration.

• no Ministry of education then a card encryption?

  Hello, I have a VPN tunnel established and now I wanted to add another, card original crypto mymap so was therefore:

  mymap outside crypto map interface

  but now I want to add a second tunnel with a mymap2 card

  mymap2 interface card crypto outside

  allows only one or the other to work, not both!

  Any ideas?

  Usually only one card can be applied to an interface. But the card encryption has the ability to define different instances within the crypto card (card crypto mymap 10, then card crypto mymap 20, etc.) to accommodate the different tunnels to various place and with possibly different settings.
