• IPsec DMVPN tunnel mode

  "Front of Cisco IOS release 12.3 (6) and 12.3 (7) T, for the spoke routers participate in a DMVPN network, they had to use tunnel mode IPSec." is indicated in the following doc:

  http://CCO/en/us/products/SW/iosswrel/ps1839/products_feature_guide09186a0080110ba1.html#wp1085369

  But I tried the mode of transport, he sees work very well. I use 12.2 (15) T. is it supposed to work? If not, why?

  Thank you

  The restriction you are referring is only in the case of your shelves DMVPN is behind NAT devices. If they are not behind NAT devices they can use a tunnel or transport mode correctly.

• IPSEC in Transport mode: what don't understand me?

  Hello world

  Please, consider the following example:

  R1-F1/0(12.12.12.1)---(12.12.12.2) R2 f1/0

  R1 has loopback1: 1.1.1.1, R2 has loopback:2.2.2.2

  Interesting traffic is between 1.1.1.1 and 2.2.2.2. We must use ipsec in transport mode. But for some reason, no matter how many times I typed transport mode under ipsec encryption, traffic get transferred via IPSEC tunnel in tunnel mode.

  Then, I have ping to 1.1.1. source 2.2.2.2 on R2:

  capture23.PNG

  

  Above, we see the traffic between 1.1.1.1/2.2.2.2 is sent in tunnel mode, even though I configured IPSEC transport mode.

  It seems that it does not matter if we have configured ipsec for the mode of transport or not, when using the crypto traffic map is transmitted using tunnel mode.

  Thoughts?

  Thank you

  You cannot use the mode of transport in this situation. You need two-heads IP here: one for end tp (1.1.1.1 to 2.2.2.2) communication and one for transport of IPsec (12.12.12.1 to 12.12.12.2). This is the reason that your router automatically in tunnel mode.

• IPSec Transport Mode question

  Hello

  We currently have a VPN site-to site mode tunnel linking our business network and our site of DR to provide replication secure on our site of Dr. I have doing some changes to firewall this weekend that will set a FW IOS Zone-Based between the 2 sites (to provide 2 firewalls for the corporate site - creation of a demilitarized zone in the middle).

  The company's website and the site of DR are all our autonomous system, so there is no NAT invovled, as all the roads are private. I have a VPN to provide extra protection to every place, because they are both accessible via Internet (I wanted that the thin ACL on each ASA outside interface) anyway, to my question.

  I implement a firewall area on the border router to provide extra protection. In the ACL of the pair area between my company and recovery site, if I change the VPN in transport mode, should work in these ACE?

  Company ASA = 1.1.1.1

  NET company = 10.10.10.0/24

  DR. ASA = 2.2.2.2

  Net DR = 20.20.20.0/24

  esp permits 10.10.10.0 0.0.0.255 20.20.20.0 0.0.0.255

  permit udp host 1.1.1.1 host 2.2.2.2 eq isakmp

  esp permit 20.20.20.0 0.0.0.255 10.10.10.0 0.0.0.255

  permit udp host 2.2.2.2 host 1.1.1.1 eq isakmp

  I'm sure that it is correct; However, I wanted to reassure a bit, before I made these changes on Saturday.

  This link describes IPSec offers a Protocol, transport and tunnel mode with these characteristics, what I mean is that the ASA as a Cisco solution does not support the mode of Transport for Lan to Lan tunnels.

  Now, sinc evous made me hesitate on my response, I made a quick test linking 2 ASA backpack and a tunnel from lan to lan using the mode of transport, the tunnel has come fine but traffic does not parameter, with reason? the ASA has been falling due to the fact that SA and the classification of the secured traffic should be peer (as tunnel normal mode circuit) in our case the ASA received a package ESP from the internal network of the ASA remote which does not correspond to the classification that's why it was ignored.

  Application of ESP and eliminated from 11.1.1.2 for outside: 10.1.1.2

  Refuse the Protocol entering 50 CBC outside: 11.1.1.2 dst identity: 10.1.1.2

  This message appears after configuring nat and acl rules to see if it accepts the traffic:

  IPSEC: Received a package of non-IPSec (Protocol = ESP) 11.1.1.2 to 10.1.1.2.

  So, as you can see it looks more like a limitation of the platform or something.

  Now, the question I have for you why the need for mode of transport?

• GET VPN tunnel mode and transport mode multicast

  Hello

  I really don't understand why GET VPN uses a tunnel for packets in multicast mode:

  Examples of a @multicast = 239.0.0.37:

  (1) here a package to GET VPN: | 239.0.0.37 | ESP | 239.0.0.37 | transport layer. Payload: : This way, he uses (two IP headers) IPSec tunnel mode.

  (2) here a package that I imagine to be better: | 239.0.0.37 | ESP | transport layer. Payload: : Mode of transport IPsec, 1 registered IP header = fewer bytes used.

  In both cases, the IP header cannot be secured, cause GET VPN Tunnel using the same multicast IP header (this is why it works so well...)

  I don't understand why Cisco uses model IPsec in tunnel mode to encapsulate packets instead of the mode of transport. I can't find a descent of answer to this question... Maybe my question is not relevant?

  Thanks for your replies.

  Concerning

  Stone,

  I quote DIG it

  It is worth noting that tunnel header preservation seems very similar to IPsec transport mode.
  However, the underlying IPsec mode of operation with GET VPN is IPsec tunnel mode. While
  IPsec transport mode reuses the original IP header and therefore adds less overhead to an IP
  packet (5% for IMIX packets; 1% for 1400-byte packets), IPsec transport mode suffers from
  fragmentation and reassembly limitations when used together with Tunnel Header Preservation
  and must not be used in GET VPN deployments where encrypted or clear packets might require
  fragmentation.
  

  In practice, reassambly concerns and initially odd behaviors with some encryption engines caused the recommendation to be tunnel mode.

  That being said, for large packages (where fresh important generals) overhead costs are minimal. For small packages (voice), the overhead is large, but the packet (after encapsulation) size should not be a problem.

• Routing access to Internet through an IPSec VPN Tunnel

  Hello

  I installed a VPN IPSec tunnel for a friend's business. At his desk at home, I installed a Cisco SA520 and at it is remote from the site I have a Cisco RVS4000. The IPSec VPN tunnel works very well. The remote site, it can hit all of its workstations and peripheral. I configured the RVS4000 working in router mode as opposed to the bridge. In the Home Office subnet is 192.168.1.0/24 while the subnet to the remote site is 192.168.2.0/24. The SA520 is configured as Internet gateway for the headquarters to 192.168.1.1. The remote desktop has a gateway 192.168.2.1.

  I need to configure the remote site so that all Internet traffic will be routed via the Home Office. I have to make sure that whatever it is plugged into the Ethernet on the RVS4000 port will have its Internet traffic routed through the Internet connection on the SA520. Currently I can ping any device on the headquarters of the remote desktop, but I can't ping anything beyond the gateway (192.168.1.1) in the Home Office.

  Any help would be greatly appreciated.

  Thank you.

  Hi William, the rvs4000 does not support the tunnel or esp transfer wild-card.

  Good news, that VPN has been implemented!

  According to the ping problem, my suggestion is to check, if some type of firewall based on host computers on both sides block ICMP requests.

  Anyway, you can still use the capture of packets on the inside of the interfaces of the two ASAs, to check if the ICMP traffic is to reach the ASA.

  In addition, you can try to enable ICMP inspection:

  Policy-map global_policy
  class inspection_default

  inspect the icmp

  Concerning

  You have a transformation defined on the SAA named ESP-3DES-MD5? Your crypto card refers to that but I don't see it listed in the config you have posted. I don't have much experience with routers, but is MD5 hashing algoritm (and why it is not)?

• IPSec VPN tunnel only to come

  Hello

  I am trying to configure an IPSec VPN tunnel between my company and a remote company for the use of FTP secure.

  I used the SDM to configure the tunnel on my router based on the information provided by the society that we are trying to connect to. The other company has provided my debug log when I was testing the connection, but I do not know how to read and what could be the problem. I hope someone here can give me an overview of what prevents the tunnel connection.

  Please let me know if you need more information.

  Thank you

  Peter Haase

  Peter,

  Good job!

  Because the tunnel is up, we must not debugs.

  I'm glad that finally it works.

• Try to import tables datapump file that makes use of the transportable mode

  
  

  
  

  Hi using impdp on oracle 11.2.0.3 and have a dumpfile that contains export of tables which makes use of the transportable tablespace mode.

  
  

  
  

  To import 3 of the cobncerned file just form tables in another database using DME, but does not

  
  

  Error
  

  ORA-39002: invalid operation

  ORA-39061: import conflicts FULL mode with the TRANSPORTABLE export mode

  
  

  {code}
  

  UserID = archive / MDbip25

  DIRECTORY = TERMSPRD_EXTRACTS

  DUMPFILE = archiveexppre.964.dmp

  LOGFILE = por_200813.log

  PARALLEL = 16

  TABLES = ZPX_RTRN_CDN_STG_BAK, ZPX_RTRN_STG_BAK, ZPX_STRN_STG_BAK

  REMAP_TABLESPACE = BI_ARCHIVE_DATA:BI_ARCHIVE_LARGE_DATA

  REMAP_TABLESPACE = BI_ARCHIVE_IDX:BI_ARCHIVE_LARGE_IDX

  {code}

  All ideas

  A transportable export must be imported using an import of transportable.  Complete using = is not a valid option.  You might be able to pass in an expression to include for the tables that you want to, but the work must always be transportable.  Your import command should look like:

  Impdp directory of the user/password transport_datafiles=/path1/pathx/dir1/dir5/filename.dbf dpump_dir dumpfile = your_dumpfile.dmp = include = table: 'In ('a', 'b', 'c') '.

  I see you are using the api, but this would be the type of command line to import.

  I hope this helps.

• Transport mode "nbdssl" is not available if the virtual machine has no snapshot

  When I use VixDiskLib_ConnectEx with a vmdk having a snapshot, I "nbdssl". If the virtual machine has no snapshot, I've always had "nbd" no matter what I specified in the parameter transportModes of the VixDiskLib_ConnectEx. I tried NULL, "nbdssl". It affects always unconditionally "nbd" when there is no snapshot.

  Is this expected behavior? If so, I am not able to write safely to a vmdk. During a recovery, I create a new vm. However, there is no snapshot. I want to get back to this vmdk.  How to work around this limitation of security?

  You use 1.1?  nbdssl restores are not supported on 1.1.

• IPSEC VPN tunnel on issue of Zonebased Firewall

  Help, please!

  I'm trying to configure a router lab ISR1921 to build the VPN tunnel with vmware vshield edge. The configuration of the 1921 is pasted below. There is not a lot of adjustment on the side of vshield really and I'm sure both sides are adapting to phase 1 & 2.

  The question I have: the tunnel can be built correctly and I also see from show crypto ipsec release encap and decap counters. However the devices on each side can communicate. That said, I can ping from 1921 to the IP of the internal interface of the vshield with IP source specified. But just no communication part and other...

  I did debugs and only "error" messages are:

  01:58:03.193 20 February: ISAKMP: (1001): error suppression node 1656104565 FALSE reason 'informational (in) State d1.

  ...

  01:58:03.193 20 February: ISAKMP: (1001): purge the node-1657220080

  I hope that I did a stupid thing to configure error, but I spent too much time on it. It is supposed to be a really simple installation... Please help!

  NAT looks fine.

  Please create an ACL with bidirecctional ACEs and add it as a group of access to the interface of penetration:

  IP access-list extended 180

  IP 192.168.100.0 allow 0.0.0.255 192.168.1.0 0.0.0.255 connect

  ip permit 192.168.1.0 0.0.0.255 192.168.100.0 0.0.0.255 connect

  allow an ip

  interface GigabitEthernet0/1

  IP access-group 180 to

  IP access-group out 180

  Generer generate traffic, then run the command display 180 access lists .

  Also, if possible activate debug ip icmp at the same time.

  Share the results.

  Thank you

• 3DES IPSEC, the tunnels on routers

  Can someone give me a limit suggested on the number of IPSEC tunnels can be deleted on Cisco 3745, 2611, 1721? When you recommend the hardware accelerator?

  The load on the routers is minimal. Memory requirements have not been specified. How much influence the memory recommendations?

  Thank you!

  I think I understand your question?

  -Maximum number of encrypted tunnels:

  -Up to 100 tunnel encrypted on a 1700 up to 300 tunnels on

  Cisco 2600 up to 800 for 2650 with aim-vpn / ep up to 800 tunnels

  For the 2600xms of cisco 2691 and 3725 until 800 tunnels on cisco

  3620 and 3640 and up to 2 000 tunnels on cisco 3660 and 3745.

• Why no implicit route for traffic from IPSec-L2L tunnel?

  In a hub-and-spoke IPSec environment, it is not difficult to implement routing by spoke to the hub.

  But on the side of the hub of a tunnel, where the gateway of last resort for traffic by spoke it, it seems almost counterintuitive than the ACL instructions and even cryptographic doesn't implicitly create a route for the traffic of the station in the tunnel at the end (talk).  It could always be replaced with a static if necessary.

  There is probably a good reason for this, but I can't think of it.  Or am I the only person who thinks it is strange... or maybe an opportunity to feature?

  Hello

  This feature exists and is called reverse road injection. The route is created dynamically (based on ACL Cryptography) and is only available when the SA is up.
