  You can try the following NAT + route map approach (method 2 in this link)

  the thing is, part of the configuration of encryption as keychain are supported because they are used in some methods of authentication for routing protocols.

  true ipsec isn't on the 9 k, the current ucode has no place for this. Next gen it maybe and we are also working on a blade or an adapter that can help with this.

  I'll try to find an official statement that ipsec on the 9 k is not supported, but the more I Googled it, the more embarrassed, I also get a lot of things 'suggests' it should work. I'm working on the correction to disambiguate.

  I also check with CRS and XR12K guys what their support for ipsec in hw.

  Will report to the time where I hear.

• Need help configuration IOS IPsec to enable communication between the VPN client

  Hi, I need help with the configuration of IPsec VPN router 2811. I want to allow communication between VPN clients, is that possible? I know that ASA, you can do this by using the command "permit same-security-traffic intra-interface".

  The fact is that each Client IP communicator installed, but when they tried to call each other, he failed. I guess that's because the connectivity between them is not permitted because of the VPN connection.

  Thanks in advance...

  If you do NAT on the router then you might want to exempt your VPN traffic to be NAt had

  Assuming that the NAT of your router is

  overload of IP nat inside source list 111 interface FastEthernet1/0

  !

  ! - The access list is used to specify which traffic

  ! - must be translated to the outside Internet.

  access-list 111 deny ip 10.10.10.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 111 deny ip 192.168.1.0 0.0.0.255 192.168.1.0 0.0.0.255

  Above two statements are exempt from nat traffic.

  access-list 111 allow ip 10.10.10.0 0.0.0.255 any<, permits="">

  I would like to know if it worked for you.

• Cisco IOS IPSec failover | Route based VPN with HSRP

  I can find the redundancy of vpn IPSec using policy based VPN with HSRP.

  Any document which ensures redundancy of the road-base-vpn with HSRP?

  OK, I now understand the question. Sorry, I have no documents for this task.

  I can see in the crypto ipsec profile that you will use under the Tunnel interface configuration to enable the protection, you can configure the redundancy:

  cisco(config)#crypto ipsec profile VTIcisco(ipsec-profile)#?Crypto Map configuration commands: default Set a command to its defaults description Description of the crypto map statement policy dialer Dialer related commands exit Exit from crypto map configuration mode no Negate a command or set its defaults redundancy Configure HA for this ipsec profile responder-only Do not initiate SAs from this device set Set values for encryption/decryption

  cisco(ipsec-profile)#redundancy ? WORD Redundancy group name

  cisco(ipsec-profile)#redundancy MRT ? stateful enable stateful failover

  I suggest that it is the same as redundancy card crypto. But no documentation or examples found...

• PIX before IPSec NAT?

  I need to set up a LAN to LAN between my 6.3 tunnel (4) Pix515e and a remote Cisco unknown device. Administrator network to our parent company in France will be setting up their end, which is the unknown device.

  Currently, the PIX is running NAT between our internal private addresses to our external address Public.

  For this IPSec tunnel, I need our private PIX NAT 24 a subnet for 24 private another subnet before IPSec.

  For example,.

  If I have a subnet internal 192.168.0.x. When the traffic has to go to France (10.40.1.x) via an IPSec tunnel, I want that our Pix NAT 192.168.0.x to 10.40.2.x before sending it via IPSec.

  (A) is it possible?

  (B) what want my Look of ACL IPSEC for interesting traffic? Wouldn't be 10.40.2.x 10.40.1.x?

  We are trying to work around a problem in subnet that overlap. The side of the France already has an IPSec tunnel on a location that overlaps with us.

  I thought I read somewhere that IPSec arrives before NAT, which would indicate that the ACL would need to be 192.168.0.x to 10.40.1.x. This could be a problem with the France is that they already have an ACL t0 192.168.0.x.

  I really hope this makes sense.

• Tripwire to PIX/IOS/CatOS agents?

  My client is installed Tripwire and they have made Solaris agents and now look at my network devices.

  Does anyone have experience with this? I can't find any useful information on the web about the functioning of these 'agents '. I almost expect an agent who lives on a server and connects to get the last configuration, rather than a process running on the box itself. However, if it IS a process that runs on the hardware platform, is it supported by Cisco, or will be the first thing I hear, technical support, be "Uninstall this Tripwire agent and see if the problem goes away."?

  I guess you mean Tripwire Enterprise.

  Tripwire supports a node "agentless". It's how they handle most I think of network devices. The server TE (frontend) has an agent installed on it and it initiates the connection and sends commands.

  Tripwire calls rules COVR (output command Validation rule). Essentially a ssh session is open, then a "sh run" is sent, then analyzed by using a regular expression. You can also use the regex for find and replace certain lines of configuration (such as operating time). Something I saw during the implementation of MARCH is that there is a connection of size max banner. I have not stumbled upon this with Tripwire but if your connections fail, try to reduce your login banner.

  I highly recommend the use of SSH and SCP. You can configure it to use TFTP too, but if you have SSH enabled on the device, it's just cleaner. Also, make sure you use variables for credentials. Tripwire has really only a right (in contrast to MARCH). You can create global variables in user name and password and then pull in for credentials when creating the node. This means that you define (or redefine) the name of user and password in 1 place instead of 500.

  Make sure that your client has licenses for the nodes of the network. You can't swap the server and network nodes. In addition, make sure you get the network rules of Tripwire.

• PIX NAT and STATIC commands

  Hello

  My script is

  Inside (LAN) (172.16.x.x) - DMZ (172.29.1.x)

  I would like to provide access to internal network to the DMZ. In addition to the ACL configuration, I can do this by using the following two methods. What are the advantage\dis advantage of each method

  static (inside, dmz) 172.16.0.0 172.16.0.0 255.255.0.0 subnet mask

  OR

  access-list ip 172.16.0.0 sheep allow 255.255.0.0 172.29.1.0 255.255.255.0

  NAT (inside) 0 access-list sheep

  What is the difference between these two?

  Hello

  Function of static and nat (inside) ACL 0 is the same, that is, traffic from inside the demilitarized zone and the opposite would be allowed. The real difference is, when configuring nat (inside) ACL 0, you are really turn off the nat for this traffic engine altogther. Using the static, you disable the nat on the pix engine, turn PIX translations sort of mistakes, as real sense his translation TI. Note: nat (inside) 0 0 0 is different from nat (inside) ACL 0. With ACL option, you can connect the two sector, with only nat (inside) 0 0 its only from the inside to the dmz, dmz inside No. In a moderated network environment, you won't see much difference in terms of performance. It's just depends on condition, you prefer one over the other.

  I hope that its clear! Thank you

• The IOS IPSec VPN configuration Cisco router

  Hi experts,

  I have not configured the VPN for a long time on the routers so I want your recommendation on best practices.

  I need to run OSPF over it, so it must be GRE over IPSec

  I googled and I see the old type of config that I used to do with the use of the crypto map. Then I see config with profile Ipsec that is applied to the interface of tunnel (tunnel protection). I also see on the manual on isakmp profile...

  Is there an example of configuration that you can provide? This is site to site VPN with PAT most basic on the interface for the remote desktop for surfing the Internet. My routers are fairly recent. One is 2821 with new 12.4 T code and another 2921 router.

  Thank you

• A Site at IOS IPSEC VPN and EIGRP

  Hello

  I have a connection of remote site to base via a VPN IPSEC router. I don't want to run EIGRP accoss VPN. Howerver I want adverstise the rest of the network from the router of core of the subnet to the remote site.

  The remote VPN subnet is managed as a route connected on the router base?

  Configuriguring a statement of network to the remote site on the router base will cause EIGRP announce the road?

  You are right.

  RRI (reverse Route Injection) is the correct way to announce remote routes as static routes on the HUB, and all what you need to do is redistribute static in EIGRP, so she is redistributed in your EIGRP.

  Here is an example configuration:

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00809d07de.shtml

  (It's about OSPF and IPSec VPN dynamics, however, the concept is the same for ipsec site-to-site and redistribution in EIGRP)

  Hope that helps.
