• ASDM IKE Phase 2 parameters

  Hello.

  I'll put up the part remote site VPN and you can't find IKE Phase 1 settings in ASDM.  Can someone tell me where I can find the phase 2 settings?  Thank you.

  If this is the case, by ASDM 6.3 above, you can use link below to verify:

  Crypto isakmp nat-traversal 20

  Last week, I configured a new L2L VPN. For IPSec phase, I have added the below mentioned lines...

  card crypto toremote 20 match address remotevpn2

  card crypto toremote 20 peers set x.x.x.x

  toremote 20 set transformation-strong crypto card

  life safety association set card crypto toremote 20 28800 seconds

  Now my question is the seq n20 crypto map is not matched with any IKE phase 1 seq no (1,9,10,30) that is already configured. But the VPN is up and working fine. How it associate a particular phase of IKE IPsec?

  If you want to configure a new virtual private network with different parameters in the IKE phase 1like 3DES, SHA1, life 86400, what are the configuration that I have to do in phase 1 of IKE?

  Kind regards

  SOM

  isakmp policy number and the number of ipsec policy do not match your ASA or with the other end. They are two distinct phases of negotiation. The ASA will compare your policy at the other end, starting with the smallest number of policies, until a match is found.

  I usually put safer policies first (i.e. with the lowest number of the police).

  To create a new policy, just add it with a new policy number, anywhere where you want in the order.

• Ports used in IKE Phase 1

  Hello world

  He had to confirm IKE Phase 1

  We use port UDP 500

  IKE Phase 2, we use ports

  ESP - 50

  NAT - T UDP 4500

  ESP TCP-1000-50
  NAT - T UDP 4500
  TCP-1000

  Concerning

  Mahesh

  IKE phase 1 (main mode/aggressive mode) is udp src and dst 500

  Phase 2 of IKE could be:

  • Protocol IP 50 (ESP)
  • NAT - T is udp src (customer) ephemeral dst (server) udp 4500
  • In former VPN clients tcp encapsulation was CBC (customer), ephemeral dst (server) tcp 10000 (10,000 in US) and 10,000 in most of the other countries

• Pre shared keys used in IKE Phase 1

  Hello world

  Need to confirm if we use the buttons pre shared during IKE Phase 1 main mode and aggressive mode

  Concerning

  MAhesh

  The pre-shared key is used in both modes of IKE Phase I. With pre-shared keys, the same preshared key is configured on each IPSec peer. IKE peers authenticate each other computer and sending a hash key data that includes the pre-shared key.

• Understanding, IKE Phase I and II

  Hi, I've been through the concept of a lot of time, but what confuses me, is encryption algorithm and a key to the DH, how they go hand in hand in IKE phase II.  I understand phase I authenticates the vpn peers and negotiates policy ISAKMP which includes Exchange Diffie-Hellman and symmetric encryption example WITH or TDES.  What I don't understand is what Exchange Diffie-Hellman (key derived from the public/private function) is used for, it encrypts the exchange of IKE2 already encrypted with DES/TDES/AES.

  Also if m do not use PFS in Phase II, would I by using the same key DH derived at the time of the phase I, if yes which is secure enough?

  Another issue is when the peers authenticate each other and then the protocol IKE phase I policy are exchanged, happens in clear text?

  Could someone please explain the process step by step in the two phases stressing precisely on the Diffie-Hellman exchange and how it is used with encryption algorithms.

  Concerning

  Sonu

  Sonu,

  Looks like you want to go back to RFC to take a peek. We have also a series of documents explaining IKEv1 and goes with debugging.

  What you miss is that in IKEv1 (main mode), messages, 5 and 6 are already encyrpted, while the previous, including Diffie-Hellman exchange are not.

  MM5 MM6 is when we exchange their identities. Those who must be protected, where the DH before negotiating.

  Phase 2 is a separate Exchange protected with the result of the phase 1. The role of DH for the phase 2 is to ensure that the encryption keys are not from previous key material.

• cfcookie expires immediately

  I can't cfcookie to stop expiring immediately.  It worked fine until recently to move to a new VPS.  Now prepare the cookies only the first time that application.cfm is run.  If you visit any other page in this same Director the cookie disappears mysteriously.

  Here is my application tag...

  < name cfapplication sessionmanagement = "yes" sessiontimeout = "KYND" = "#CreateTimeSpan (0,3,0,0)" # "setclientcookies =" "setdomaincookies ="yes">"

  http://www.kyndoutdoors.com/DBF/_kynd-controller/my-kynd.cfm

  Use timmyv as the username and the password.

  Cookies are NOT deleted. The problem is the duplication. And more specifically, the problem is cfparam I encouraged to remove them.

  Your first decision in your test is the following:

  (btw, you don't need sharp in this code or in one of the other cfif statements in your code. Delete them, they are so ugly)

  Well, kp_id is empty and he is not. The cookie exist twice, once with and once without value. CF uses the one without value. Both are sent, order of which they are sent in the results in the cookie being blank.

  This is the HTTP request sent:

  GET /dbf/cookies.cfm HTTP/1.1

  Host: www.kyndoutdoors.com

  User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; RV:16.0) Gecko/20100101 Firefox/16.0

  Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

  Accept-Language: en-US, en; q = 0.5

  Accept-Encoding: gzip, deflate

  Connection: keep-alive

  "" Cookie: kp_id = ""; KP_ID = 13608; KP_USERNAME = timmyv; KP_PASSWORD = timmyv

  The important line is the last. TWO KP_IDs are sent. One is empty, we're not. CF must use the first one it receives.

  Nevertheless, delete the cfparam (you will need to add a control of existence to your cfifs that make use of this cookie var), delete your cookies and try again.

• remote users access site ipsec tunnel

  How to configure the ACL and the road to allow remote users access to site ipsec as local users?

  Current scenario is

  1. distance users (192.168.2.0/24) ipsec <->Cisco 870 (192.168.0.0/24)

  (2 cisco 870(192.168.0.0/24) ipsec tunnel <->cisco 1811 (10.0.0.0/24)

  Now remote users can access the 192.168.0.0 network, no problem, but how they can access 10.0.0.0 network?

  I guess I can do like this:

  1. in cisco 870, site to site ip 192.168.0.0 tunnel allow 0.0.0.255 10.0.0.0 0.0.0.255

  (add) permit ip 192.168.2.0 0.0.0.255 10.0.0.0 0.0.0.255

  2. in the site-to-site vpn cisco 1811

  (add) permit ip 10.0.0.0 0.0.0.255 192.168.2.0 0.0.0.255

  3. in settings vpn split cisco870 add the 10.0.0.0/24 network

  Is this fair?

  Thank you.

  You must configure the interesting traffic that an ACL contains the source is remote destination as local LAN and LAN.

  Hey,.

  is the remote end ASA as well?

  If so, the capture below on the ASA:

  capture capout match udp host host interface

  The tunnel gets stuck on MM_WAIT_MSG2 for 2 reasons:

  1 either a problem with the policies of the phase 1 of the remote end or

  2 UDP 500 is not reaching the remote end or the remote end sends the packet UDP 500 back and can't the ASA local.

  Edit: can you put the configuration on both sides of the tunnel? Otherwise re - check once more the configs on both sides

• Cannot complete the tunnel ' phase 2 ', by establishing a site to site VPN.

  I am trying to establish a VPN tunnel from site to site between a Cisco 1921 and an ASA.

  I am debugging using:

  Debug crypto ISAKMP

  Debug crypto ipsec

  No debug message is coming on the 1921.

  The following debug message returns constantly to the ASA:

  15 jan 16:42:55 [IKEv1]: Group = 184.1.126.140, IP = 184.1.126.140, construct_ ipsec_delete(): No. SPI to identify the Phase 2 SA!

  ASA config: http://pastebin.com/raw.php?i=wgTxe3gF

  1921 config: http://pastebin.com/raw.php?i=TEihijEF

  Why won't the two establish a VPN tunnel?

  It's very strange that ASA appears the tunnel, but the router does not work. It seems that the router is waiting for authentication.

  You can add-

  crypto isakmp key address 184.1.96.42 no-xauth

  You can debug isakmp and ipsec on the router and display it?

• VPN - failure IKE Phase 1

  Hi all

  IM challenges with a site to site vpn where it cannot be initiated/based on one side of the VPN.

  For 1 side of the vpn, I could ping everywhere without problems and vpn tunnel is established successfully, but when I try it the other side of the vpn it never sets and the State is stuck in MM_KEY_EXCH.

  I have verfied configurations at both ends and everything seems to be going well (see below), also, please find an isakmp crypto debugging attached to the router that does not seem to establish the vpn - no idea why this is a failure?

  VPN is set up on a C837 to a C857.

  Thank you very much

  That could very well be causing this problem.

  If you have the static configuration to the dynamic for IPsec between two routers, please make sure that you have this configuration:

  http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a0080093f86.shtml

  You see that the dynamic IP site has a normal static encryption card, but the side static IP has a dynamic encryption card.

  This example assumes that you do NAT too.

  With this configuration, the tunnel can only be started from the dynamic side.

  It will be useful.
