IPSEc between PIX devices

• IPSEC VPN between Pix 515E and 1841 router

  Hi all

  BACKGROUND

  We have implemented a site to site VPN IPSEC between a Pix 515E 8.0 operation (4) and an 1841 using static IP addresses at both ends. We used CCP on the router and the ASDM the pix to build initial tunnels. Now the site with the router is evolving into a dynamic IP address from the ISP so we have implemented dynamic DNS to update dynamic IP address.

  PROBLEM

  The problem is that ASDM will not allow us to set a domain as the address of peers, it will not accept an IP address. We believe that the solution will be to remove the static Crypto map and replace it with a dynamic Crypto map on the side of Pix. Our questions are simply; is this the best solution? can change us the original static list or is it better to delete and make a new dynamic encryption card? Y at - it a shortcut to change the config command-line? This is a real network, so just check it out before make us any changes on the live kit.

  Any help much appreciated.

  You don't have to change anything when the peer-address changes. The dynamic crypto map aims to take dynamic peer connections. The only thing to remember, is that only the dynamic peer can initiate the connection. And you reduce your security if you use Pre-Shared key that now you can use a generic-PSK character.

  As I remember, the PIX / ASA does not support the dynamic use of FQDNs for peer-resolution. This feature is supported in IOS.

  For a feature, it would be preferable to static IP addresses on both sides.

• cannot connect to ipsec between ASA5515 to cisco891

  I'm trying to connect ipsec between ASA5515 to cisco891, more cisco3825.

  ASA5515's version (8.6).

  cisco891 is ios (15.4).

  CISCO3825 is ios (15.1).

  In, cisco891.

  do not type 'card crypto' next 'set the peer address' and 'mach '.

  Cisco3825.

  error message "MM_WAIT_MSG3" then stops.

  How to connect to ipsec?

  Hello

  IF on the cisco 891 router, you try to type the commands "Crypto" , and it does not work, make sure that you have a security K9 license so you will be able to use the security features, you can check this with--> them show version.

  Now on the cisco 3825:

  The MM_WAIT_MSG3 receiver is return his policy IKE initiator. Initiator sends BA/hash/dh ike policy details to create the first contact. Initiator will wait at MM_WAIT_MSG2 he hears of his peers. Hang ups here can also be due to offset device vendors, a router with a firewall in the way, or even ASA version incompatibilities.

  -While the IKE encryption on the router and on the SAA strategy? Are they match?

• Is it possible to sync only bookmarks in one device, for example and all the other stuff between other devices?

  Hello.

  I have 3 devices. 2 of them are at work, so I don't want to sync items such as extensions (xnotifier, for example, is to synchronize my CPA), passwords for my PC at home with these two devices. But I want to synchronize my bookmarks and other things. Is it possible to separate between different devices sync settings?

  Thank you.

  You may need to use two separate sync accounts, if this is not possible with a single account.
  As you cannot use both accounts at the same time on a device, you will need to disconnect the computer which is the main device and (temporarily) connect to another account only synchronize to the other account to sync bookmarks.

• IMessage does not sync between all devices

  My ipad/Mac will not sync with my iphone imessage. Until I reinstalled my Mac wasn't a problem. If I type a message to someone in imessage from my Mac or my iPad, it does not display in my iphone vice versa.

  imessages from my iphone will not only do not appear in the other two devices, but the response I get will not pass to the device, sure I typed the message. Even the opposite effect. Messages and responses to Mac/iPad won't go on my iPhone imessage.

  Should what setting I change to get everthing again between all devices sync?

  Have you checked that you have activated the same send to and receive to address on all devices.

• Messages between Apple device

  Is it possible to manage Messages between Apple devices?

  Meaning: When Dial / change / deletion of Messages in one device from Apple, other Apple devices will be updated?

  All with the same Apple ID.

  As in Mail / Safari etc...

  Thank you.

  Deleting messages on a device will not remove them on the other. They are specific to the device. It does not work as a Courier IMAP.

• Problem of password of account, without that we can connect to the network on this computer. The error indicates, "the trust relationship between this device and the network is no longer valid.

  Hi, I hope you can help with this problem. A friend has 6 computers networked to a Tower Server and have a problem. A worker student put computers into hibernation, and since then, nobody can connect to the network on this computer. The error indicates, "the trust relationship between this device and the network is no longer valid. I tried to get into the pc to try removing network and replace it, but I can't get on the Administrators account because it has been disabled. I'm at a loss on how to proceed. My friend cannot afford a service call, so I'll try to help him.  Thank you

  If the computer is on a domain then there are at least two accounts that can be used to remove the computer from the domain:

  • A domain administrator account.
  • A local administrator account.

  When your friend has launched Windows for the first time after buying the machine, he was prompted to enter the name of an account. This account is created automatically with administrator privileges. He should use it now.

• Site IPSec between RPS and IOS.

  Hello

  I really hope that Andrew Hickman, author of DOC-16927 and DOC-23028 can help with this.

  I created a Site to IPSec VPN between our SRP527W-U and CISCO881-K9 (SRI) running IOS 15.0 (1) M3.

  It is the first branch to use a PRV. I use a card dynamic encryption (that we have more than one branch, and ESP was a dynamic public IP address).

  Our other branch (also runs an international search report) is a GRE over IPSec VPN, traffic between subnets it passes over the GRE tunnel. It works very well. The goal here is really to achieve the same (GRE over IPSec) between the SRP and the SRI. Similar to our other branch.

  Hi Trent,

  My apologies, I misread your first post - I thought that you were talking about the question of access and the IP address of the PRS via IPSec (that part is fixed).

  I fear for your real question, there is no answer.  The SRP500 does not support GRE over IPSec (just one or the other).

  Kind regards

  Hello Krishna

  If possible and feasible to try and downgrade the IOS 12.3 (9) to a low-level code as 12.3.6. But, make sure that the image is a single k9 and supports VPN. Also upgrade the pix to 6.3.3.

  Assuming that the keys are the same, your configs find ok. Him debugs it seems its not able to pass from the phase 1 properly

  could contribute to modify the code.

• VPN connectivity between three devices

  Hi all

  In this scenario, we have 3 cisco devices: 1 Cisco router connected to another 2nd Cisco router with IPSEC site-to-site VPN and the 2nd router Cisco is connected with IPSEC site-to-site to the 3rd ASA firewall.

  1 router has lan network 192.168.1.0/24 linking 2nd router lan via VPN site-to-site

  2nd router has lan 192.168.2.0/24 linking 1 router & 3rd ASA lan via VPN site to site (intermediate device)

  3rd ASA FW has lan 192.168.3.0/24 linking 2nd router lan via VPN site-to-site

  My question is: is it possible for the 1st network of routers can communicate with 3rd ASA network by changing only config Router 1 and 2 and how?

  Thanks in advance.

  Yes it is possible, but the solution is not very "elegant". If you could change the config of the ASA-3 there are two ways to cope:

  1. A tunnel between Rtr - 1 and ASA-3
  2. Extend existing tunnels to carry also the traffic of LAN1 LAN3

  Without this possibility, you can still obtain access to LAN1 to the LAN3. To:

  1. extend the R1 - R2 tunnel to protect the traffic of LAN1 to LAN3
  2. Configure RTR - 2 to translate the addresses of the LAN1 to the address in LAN2.
  3. Now this traffic can be sent through the tunnel between R2-ASA3

• VPN IPSEC between two networks

  Hello-

  For these last days, I've been banging my head against the wall with this problem.

  I have two IP networks that have the same IP that I need to create an IPSEC tunnel between.

  Here's a crude diagram:

  192.168.1.0/24--[Cisco 1920] - Internet-[cisco RV082]--192.168.1.0/24

  I know that I should make some sort of NAT, but from what I've been through the RV082 it's not like he can do it.

  I tried to get this work is this:

  192.168.1.0/24--[Cisco 1920] - Internet-[cisco RV082]-192.168.33.0/24-[Belkin N300 consumer router]--192.168.1.0/24

  But once I changed LAN IP of Belkin 192.168.1.1/24 I lost connectivity to the "WAN" port, I was clicking on the side LAN of 1920. (I think he was trying to route the traffic via the LAN port is even if it is entered on its WAN port)

  Someone has some tips to get me going in the right direction?

  Thank you

  Greg Smythe

  Hi Greg,.

  If you have same subnet on both ends, then Yes you are right the NAT is the only option. You need to do NAT on both devices. As you say that RV is unable to do so I don't think that if you have any othe roption to change the subnet on one of the end. Which is not an easy option

  Thank you

• Inside the interface of access IPSec on PIX

  Hi all

  I need advice with the following problem.

  I have PIX 515E with 3 interfaces inside.

  DMZ and outside, to 6.3 (3). Is it possible to access DMZ more inside the interface with IPSec of CISCO VPN client? IPSec creates a tunnel, the customer

  has a new address of the address pool, but

  in the paper, I have a message: not found translation etc... When I try to

  reach any device in the DMZ. The reason seems

  be with nat (dmz) 0, which should be inside the DMZ (social security social security 50 0). Even if I use nat (dmz) 0-list of remote access apart from it does not work. Any tips?

  Thank you

  Zdenek

  Hello

  Can you check if you are able to access the DMZ from the inside? If so, then u shud be able to access DMZ to connect remotely. This is because once the VPN client obtains the IP address of the inside pool, it's as good as he is in your home LAN. You can try putting inside DMZ natting... I mean put this command nat 0 because inside the DMZ, which will allow access to DMZ devices inside.
