• Phase 2 question [all IPSec security association proposals considered unacceptable!]

   
  Hello
   
  I have problems to configure an ipsec L2L with my 1921 tunnel and ASA.
  I have to use aggressive mode as the 1921 does not have a fixed IP.
   
  Phase 1 of IKE's fine, but then I get the following message:
   
  5 11:00:14 Group April 1, 2014 713119 = CIT-TEST, IP = YYY. YYY. YYY. YYY, PHASE 1 COMPLETED
  5 11:00:14 Group April 1, 2014 713904 = CIT-TEST, IP = YYY. YYY. YYY. YYY proposals, any IPSec security association has deemed unacceptable!
   
  and the tunnel manages not to come.
   
  So I guess it's one about identifyed networks, so I suspect the transformation defined not to be good.
   
  ASA:
   
  # Crypto card #.

  But tried with different combos on the 1921 but no luck. What Miss me?
  Could anyone help with the transformation on the 1921 set command, it's a little different than on the ASA.
  Can anyone help?
   
  Best regards

  You don't show us the configuration (if one is called) for Phase 2 of ASAs transform-set.

  There should be an installer matching your 1921 something as in this example:

• change the lives of the IPSEC Security Association

  Hello

  If I use the

  order of the life of-association of IPSEC crypto security, that does not hold for all customers? I'm trying to change it only for an IPSEC security association and I don't want to interrupt any existing VPN client.

  is it possible to put it for a client?

  Thank you!

  Lisa G

  You can change it in a configuration card crypto for each individual connection. Since you don't specify what your vpn device ends on however, I can't give you a specific example.

  the command you gave is global, for which there is already a default lifetime. 'local' lifespans for individual crypto cards override this value.

  also, if two peers differ in their lives during the negotiation, they are "supposed to" choose the smallest value, but still not connect.

• IPsec Security Association keep it up

  Hello community,

  Customer has about 50 distance 871 s (home) with IP phones.

  Main site has ASA 5510 sheltering the CUCM.

  Problem is...

  When user1 calls user2 there no audio data (since there is no built between remote users IPsec security association).

  The fact that user1 called user2 built IPsec between ROUTER1 and ASA, but since there is no IPsec security association for users between ROUTER2 and ASA, audio fails.

  If User2 calls user1 now, then the call is successful, because the SAs are built:

  IPsec security association between ROUTER1 and ASA for the traffic of user1 and user2

  IPsec security association between ROUTER2 and ASA for the user1 user2 traffic

  So, the problem is that both parties must open up traffic to make this work.

  What I did to solve the problem, is to configure IP SLA on routers to send a PING packet every 10 minutes at their home by peers (thus keeping the SAs between remote sites all the time).

  IP SLA works, but I'm looking for a better way to solve the problem of having to manually launch the traffic (DMVPN or running as one routing protocol does not work with the ASA through the tunnel).

  I guess to increase life expectancy IPsec Security Association is another option.

  Looking to get recommendations, thanks!

  Federico.

  Hi Federico,.

  Have you considered EzVPN/Easy VPN, with ASA like server EzVPN configuration and Clients (routers/ASA5505) as clients of EzVPN? This would create the tunnel as soon as it is configured.

  In addition, apart from the increase in the life expectancy of the AA (which is basically report to generate a new key stage 2), you can configure vpn-idle-timeout to be 'none' in the group-policy framework of the SAA.

  Any thoughts?

  Kind regards

• Question about the life of the IPSec Security Association

  Hi all

  I'm confused about life. A book, they said that you should service life of the peer to keep two exact same, otherwise you can not establish the tunnel. But I saw another book says you can use different to life (time interval or byte count), two peers will choose the lower one.

  Please help me. Thanks in advance.

  Banlan

  There are two lives involved with IPSec, Phase 1 (ISAKMP) and Phase 2 (IPSec) connections.

  With the Phase 1 tunnel, if the initiator has a longer life than that the answering machine, the answering machine does not accept the connection, then it is certainly preferable to keep your the same Phase 1 lives.

  Phase 2, life will be negotiated at the lower of the two values regardless of intiates, if it is not serious. Always advised to keep living the same since you can run questions of negotiation with devices from different vendors.

• IPSEc between PIX devices

  Hi guys I'm trying to create an IPSEC tunnel between a 515 and a 506.

  Of course, it does not work, otherwise I would not here :)

  The 515 has these entries to the tunnel:

  melbMap 22 ipsec-isakmp crypto map

  correspondence address card crypto 22 22 melbMap

  peer set card crypto melbMap 22 10.43.136.10

  Crypto ipsec transform-set esp - esp-sha-hmac DSAT_CCIS_SYDset

  There is also an isakmp for the peer key

  The 506 I have this:

  IP 172.17.217.0 allow Access - list SHEEP 255.255.255.0 172.29.152.0 255.255.255.0

• UC500 and IPsec VPN client - disconnects

  Just throw a question out there.
  I have a UC560 running uc500-advipservicesk9 - mz.151 - 2.T2 site HQ.  Remote users, about 8 of them, attempt to connect via IPsec VPN (v5.0.07.0440) HQ clients to access files, etc..  The behavior I see is 5 users to connect successfully, but only 5.  As soon as more users trying to connect, they have either:

  1. connect with success for a minutes, then unmold
  2. get a 412, remote peer is not responding
  3. connect, but someone of another session kickoff.

  Users use the same VPN profile, but with names of single user and passwords.

  Here are some of the CPU configs for VPN clients

  I opened a case with TAC on this and they do not understand what is the cause.  For them, it looks like a bug without papers.  And their recommendation is to reboot, upgrade or try configuring L2TP for remote users.

  Thank you

  JP

  JP,

  An update of IOS is worth it, even if him debugs seems to indicate that there is a problem with the client. If possible, I always suggest test with another client to see if it is unique to the Cisco VPN Client on Win7. Regarding the limit of 20 tunnel, it is very probably the number of IPsec security associations. If you issue a 'show crypto eli', this example displays the number of Sessions that are currently active IPSec.

  HTH,

• Reseting ipsec on PIX 501

  Hi all. Just a quick question. I can't seem to find how to reset ipsec on PIX 501 and force her to negotiate again and I also want to reset statistics for ipsec his. I know that I saw somewhere, orders, but now can't seem to find the commands from anywhere.

  Thanks in advance for any help.

  Hello...

  Config mode...

  ISAKMP crypto claire his

  - and -

  clear crypto ipsec his

  PS. You can find the commands on the PIX by entering the configuration mode by typing...

  PIX01 (config) # clear cry?

  Hope the above helps and please note messages!

• DMVPN and IPsec CLIENT?

  Hello

  I was wondering if it was possible to use CRYPTOGRAPHY even for both: DMVPN and CLIENT IPsec?

  To make it work, I have to use 1 crypto for the DMVPN and 1 crypto for IPsec, both systems operate on the same router, my router TALK can connect to my HUB router and my computer can connect to the router "HUB" via an IPsec tunnel.

  Is their any way to make it easier, instead of doing configs in a single router for more or less the same work?

  My stitching question may be stupid, sorry for that, I'm still learning, and I love it

  Here below the full work DMVPN + IPsec:

  Best regards

  Didier,

  Some time ago, I wrote a bit on VT, you should be able to find information about the server ezvpn DVTI it.

  https://supportforums.Cisco.com/community/NetPro/security/VPN/blog/2010/12/08/advantages-of-VTI-configuration-for-IPSec-tunnels

  The configuartion you have right now is the way to strives for ezvpn, with the new way DMVPN (protection of tunnel).

  If it is true for the most part, it is best to go on the learning curve Moose and go everythign new configuration.

  With EZVPN you can always assign IP from the pool by group ezvpn or external authorization ;-)

  Anyway let me know if you face any problems.

• Difference between webVPN, SSL vpn and ipsec client

  Hello

  We just bought an ASA5510 and I am trying to understand the difference of the possibilities mentioned VPN. Can anyone describe the differences and use scenarios of all types of remote access vpn of the asa?

  Thanks in advance.

  Rgds,

  Rasmus

  Hi Rasmus,

  They use different SSH and IPSEC protocols, and there is also of course in terms of security.

  SSL is easy to deploy than ipsec. Imagine that you have 200 + users and to connect to the vpn, you must give them the pcf file and client software, which is not required in the case of SSL.

  Kind regards

  Please note if assistance

• SSL VPN and ipsec

  For CISCO1841-SEC/K9, ssl and ipsec vpn connection vpn how, we can make and? The datasheet is not any specific number.

  Thank you.

  With the PIX and ASA, the number of peers is specified in the license and limited to the number specified in the license (so in support of peers, you must update the license). From my experience of the IOS application does not bind the number of peers for what anyone in the license. So, if you buy a feature set for IOS router supports IPSec/SSL VPN, then this is your license for IPSec and SSL peering (no separate license is required).

• The GRE and IPSec

  We currently have several sites with ISAKMP/IPSec tunnels between routers 2800 and we need some of them migrate to the GRE with IPSec tunnels. Are there problems with endpoint tunnels GRE and IPsec on the same router and interface?

  I didn't know all the problems - apart from the router doing the encryption/decryption & GRE encapsulation/decapsulation, just be respect for traffic through the put.

  I have noted problems with traffic GRE and MTU problems. Cisco recommends a MTU of 1440 at Discretion, I would say that set 1400.

• ISAKMP and SAs

  I just want to clarify something.

  When all Phase 1 and 2 IKE should I expect to see an ISAKMP SA on each endpoint?

  For example, when I do ' sh crypto isakmp his "on each PIX should there be a no matter who started the connection?

  In this way, but the life time are slightly different.

  Yes, you should. If you do not see the SA, disable the session isakmp and create it again and see if it returns

• Given that I uninstalled avast! antivirus and installed Bitdefender Internet Security 2015 Thunderbird asked to accept an invalid certificate or not.

  Given that I uninstalled avast! antivirus and installed Bitdefender Internet Security 2015 Thunderbird application if you want to accept an invalid certificate when you try to receive new messages.

  Please take a look at the two attachments (it seems to be a problem with the download of jpg files).

  Obviously Bitdefender manipulates the certificate (no doubt to be able to scan the e-mails via an SSL connection). But I'm not sure.

  Would you recommend to confirm an exception for this certificate (permanently)?

  Thanks in advance.

  Greetings

  Marco

  Thank you, christ1.

  I discovered that after disabling SSL scanning in Bitdefender, this problem no longer exists.

  Maybe this can be seen as a confirmation that the certificate belongs in reality to Bitdefender. Because it is my concern, that is the validation of this certificate to make sure that Bitdefender is the transmitter.
