Validation of the IOS VPN peer identity IP with NAT - T

I just lost a lot of time to understand this behavior of the IOS. My conclusion reached: If you work with the good old peer identity address validation in profiles ISAKMP and the peer you are talking about is located behind a NAT, you must use the private IP address of the peer in the command "adapter address of the identity". I thought that NAT - T takes care of the translation in all sections of required configuration, but here especially, seems not so much. The interesting thing is that for all other orders, you must use the public IP address.

See the following example (showing only the relevant articles with statements by peer inside):

door-key crypto OUR_KEYRING

key pre-shared key address 1.2.3.4

Crypto isakmp PROFILE_NAME profile

VRF TEST

key ring OUR_KEYRING

function identity address 192.168.99.5 255.255.255.255

OUR_MAP 6 ipsec-isakmp crypto map

defined peer 1.2.3.4

the value of PROFILE_NAME isakmp-profile

Does anyone know if this is normal or if it is a bug? It would be useful and consistent if NAT - T changed the identity of the peer address during the phase 1 negotiation, then we would not deal with peer private addressing within site to site VPN configs. I also think of IP scenarios that overlap that may occur when you work with dealing with private peer.

See the release of relevant debugging in the attachment, after documenting a failed connection attempt (using the public, NATted IP of the peer in the command 'fit the address of identity') and once a following connection attempt (using the IP private, internal counterpart).

My router is a C2951 with IOS 15.3 (2) T2. The counterpart is an ASA (version & unknown config so far, but I'm sure that the other engineer did not indicate what it is using a private address in its config, despite my session from behind a NAT router, too).

Thank you & best regards

Toni,

Problem with identity is that it is an encrypted package (in Exchange MM) so cannot be changed in transit, so that a host may not know reliably it is the external IP address (it can make assumptions, but he doesn't know how long it is valid for).

Also if you "NAT 'd" identity you can't the difference between two devices behind same NAT/PAT on end of answering machine.

There are some implmentations IKE allowing IKE to identity type and value to specify manually. IOS not among them.

Yes decouple us identity and peer of the intellectual property, it adds flexability with a few corner cases which may arrise.

Yet another reason why NAT is evil?

    Hi all

    Hey Damo,

    Assuming that you don't need to IKE to listen to the world, but only to specific counterparts, you can possibly use the access map command option, for example as follows:

    test from the list of access permit udp host 10.48.67.145 interface outside isakmp eq

    extended access list test deny udp any any eq isakmp

    extended list permits all ip one access test

    Access-group test in interface out-of-control plan

    This will prevent other hosts to reach the IKE process:

    % 4 ASA-106023: Deny udp src outside:10.48.67.144/500 dst identity:10.48.67.76/500 by access-group 'test' [0xe4b28725, 0 x 0]

  • Based on the IOS VPN Lan-to-Lan (NAT and route map Questions)

    Hello world

    I worked on my review of CCNA security and I have a question about this stage

    LAN1 192.168.0.0/24---(routeur HQ)--10.10.10.0/30--(INTERNET)--20.20.20.0/30--(routeur Branch) - LAN2 192.168.1.0/24

    I use 10.10.10.0/30 and 20.20.20.0/30 networks assuming that these are public addresses (is just a laboratory).

    I read that if I want to make the VPN tunnel while I using NAT I must exclude valuable traffic from the NAT process so I look on the database of cisco for more help and I found this (look at the 3660 router configuration):

    http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a008045a2d2.shtml#T1

    so, I applied this config for my routers, so the config is:

    IP nat inside source map route sheep interface fastEthernet0/1

    access list 110 deny ip 192.168.0.0. 0.0.0.255 192.168.1.0 0.0.0.255

    access list 119 permit ip 192.168.0.0. 0.0.0.255 any

    sheep allowed 10 route map

    corresponds to the IP 110

    I didn't really understand who is using the command route-map here, so I made this configuration:

    IP nat inside list sheep interface FastEthernet0/1

    sheep extended IP access list

    deny ip 192.168.0.0 0.0.0.255 192.168.1.0 0.0.0.255

    Licensing ip 192.168.0.0 0.0.0.255 any

    Two of them worked I could translate my LAN addresses to the public to address internet and also could establish the VPN tunnel. So my questions are:

    1. What is the purpose of the road-map command?

    2. What is the difference between these two configuration?

    3. which one I should use and in what cases?

    Thanks in advance

    Jose

    Jose,

    Very good questions and in fact no need to the road map it.

    Personally, I like using course maps because it allows much more flexibility than simply ACL setup, but in order to bypass the NAT source IPs, there is no need of route-maps and you can do this with the ACL directly.

    I personally always use road-maps just because I can (route-maps are cool) haha

    Route-maps are very useful in other scenarios where you need to put more of conditions or factors.

    Remember that it is almost always more than one method to accomplish a task... which is one of those cases.

    It will be useful.

  • local host to access the vpn site to site with nat static configured

    I have two 881 routers with vpn site to site between them. I have a static nat on the router for a Web server that is accessible from the internet. I can't access the Web server through the vpn. All other traffic is fine its VPN. I think that there is a problem with the NAT. Here are the relevant configuration lines.

    IP nat inside source overload map route SDM_RMAP_1 interface FastEthernet4
    IP nat inside source static 192.168.150.2 bonnefin map route SDM_RMAP_1

    allowed SDM_RMAP_1 1 route map
    corresponds to the IP 100

    access-list 100 deny ip 192.168.150.0 0.0.0.255 192.168.123.0 0.0.0.255
    access-list 100 permit ip 192.168.150.0 0.0.0.255 any

    You should be able to access the web server with its IP private (192.168.150.2) through the VPN connection.

    If you just add the VPN and the road map, try to clear the existing translation and see if you can access it via its private of the Remote LAN VPN ip address.

  • VPN site to Site with NAT (PIX 7.2)

    Hi all

    I hope for more help with config PIX.  TBH I would classify myself as a newb on PIX, only dabbling in it every 6 months or so...

    I have to configure a VPN site-to site between our UK and US Office, to replace our frame relay link.  I have configured multiple VPN site to site on the before PIX, so am reasonably okay with the appearance of the config of who.  What is a new concept for me is the needs of NAT'ing between the IPSEC tunnel.

    The U.S. Agency requires us to NAT source addresses (i.e. 192.168.1.0) usable on their side address (i.e. 143.102.89.0).  The tunnel must then be set to encrypt traffic between 143.102.89.0/24 and 172.24.0.0/14.

    I added the following config and hoping to test it at the U.S. office happens online today.

    If I Ping from 192.168.1.0 to 172.24.x.x source and run a SH NAT inside, the NAT translation seems good.

    is the intellectual property inside 192.168.1.0 255.255.255.0 outside 172.24.0.0 255.252.0.0

    NAT (inside) 1 access list policy-nat-dallas

    Global 1 143.102.89.x (outside)

    The static statement that you configured previously will take precedence over the above. So the printer gets statically using a NAT to 143.102.89.10, and the rest can do another ip address 143.102.89.x PATed.

    Please note that for PAT, traffic can only be initiated from 192.168.1.0/24 LAN to 172.24.0.0/14, not the other way around.

    Hope that helps.

  • VPN site to Site with NAT and Port forwarding on a 871

    Hello

    Could someone please look at the config 871 router attached and tell me where I'm wrong!

    VPNs all work, work, BUT anyone trying to connect to a port that is sent through the VPN port forwarding fails.

    In the config attached Port 3389 (RDP) is sent to an internal server, if you connect to the external interface Internet connection is made and it works well, but if someone tries to connect to the IP address internal to that same server through VPN, it does not.

    We've added commands to stop working on the lines VPN NAT, but these do not seem to work.

    What Miss me?

    Thank you in advance and I will adjudicate all useful responses.

    It is a common problem. Yes you added controls to prevent NAT to work above the tunnel, but your static nat port to port 3389 takes precedence over the generic nat command, and there not all orders top to prevent it is nat would be above the tunnel.

    I wrote an example configuration for this some time, see here for more details:

    http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a0080094634.shtml

    If all goes well, he explains everything. Note that it is for a general order static host, not a static port that you have, but the concept is exactly the same. Just add a statement roadmap on the end of your static command of the port, and this route map - will reference an ACL that denies are used when going up above the tunnel.

  • VPN Hub and Spoke with NAT

    Hello! I have a VPN network star topology, I need configuration for our customers to access. I have 3 points of endpoint in this example: VPN, Pix 515e and Linksys RV042 hub. The hub is the site of our parent company, the Pix 515e is our data center and the RV042 is at the customer's site. What I currently have is a VPN connection between our Pix 515e and the hub, and another between our Pix 515e and the RV042 VPN. What I need is for the server on the client (RV042) site to talk to the hub network via our Pix 515e. I also need to be coordinated traffic so it looks like it's from the same subnet on our Pix 515e to the hub.

    Interior - 192.168.71.1

    The hub allows all traffic to my Pix 515e on subnet 172.16.3.x and vice versa. The RV042 allows all traffic from 172.16.3.x to talk to 192.168.71.x and vice versa. I need to get 192.168.71.5 on RV042 network 10.1.6.x the network hub through the Pix 515e and make it look like its 172.16.3.71 entry. So I need NAT traffic in the tunnel to another tunnel. Attached config running under the direction of privacy. Any help is greatly appreciated.

    On PIX you need a static policy statement,

  • Cisco ASA VPN Site to Site WITH NAT inside

    Hello!

    I have 2 ASA 5505 related to IPSEC Tunnel VPN Site to Site.

    A 192.168.1.0/24 'remotely' inside the network and a local "192.168.200.0/24' inside the network (you can see the diagram)

    The local host have 192.168.200.254 as default gateway.

    I can't add static route to all army and I can't add static route to 192.168.200.254.

    NAT the VPN entering as 192.168.200.1 or a 192.168.200.x free to connect my host correcly?

    If my host sends packet to exit to the default gateway.

    Thank you for your support

    Best regards

    Marco

    The configuration must be applied on the SAA with the 192.168.200.0 subnet it is inside, there must be something like this:

    permit 192.168.1.0 ip access list VPN_NAT 255.255.255.0 192.168.200.0 255.255.255.0

    NAT (outside) X VPN_NAT outside access list

    Global (inside) X Y.Y.Y.Y (where the Y.Y.Y.Y) is the ip address

    If you have other traffic on the vpn through the tunnel that requires no nat, then you must add external nat exemption rules since these lines above obliges all traffic through the asa to have a nat statement.

    See if it works for you, else post your config nat here.

  • I need VPN gateway to gateway with NAT for several subnets, RV082

    I have a pair of RV082 routers and I would like to configure a gateway to gateway VPN tunnel, as described in a book, "How to configure a VPN tunnel that routes all traffic to the remote gateway," (name of file Small_business_router_tunnel_Branch_to_Main.doc).  I followed this recipe book and found that my while the main office has internet connectivity, the branch subnet is not an internet connection.

    Routing behaves as advertised, where all traffic goes to the seat.  However, the 192.168.1.0 subnet in the branch receives no internet connectivity.  I read in other posts that the main router will provide only NAT for the local subnet, not the Management Office subnet.  Is it possible to configure the RV082 router to provide NAT for all subnets?

    If this is not the case, what product Cisco will provide connectivity VPN Tunnel as well as the NAT for all subnets?  The RV082 can be used as part of the final solution or are my RV082s a wasted expense?

  • VPN site to Site with NAT

    Hello Experts

    We intend to set up a VPN site-to site between two sites, sites, Site & A B such as shown in the attached diagram.

    The LAN on SIte A is 10.8.1.0/24 who are planning to NAT on the ASA5505 to 192.168.42.0/24 because this is the range that is allowed on the firewall on the remote end (Site B ASA 5520)

    What type of configuration requires we on the firewall of the Site regarding the interesting traffic.

    Natted IPs will be the interesting traffic?

    Is there another thing we have in other mind while configuring the ASA for the scenarios.

    Help would be appreciated.

    ACL "crypto-NAT" of my example will be the NAT traffic that source of 10.8.1.0/24 for 10.3.0.0/24 to match 192.168.42.0/24.

    For example:

    10.8.1.1 will be coordinated to 192.168.42.1 when traffic is destined to the 10.3.0.0/24 subnet.

    10.8.1.2 will be coordinated to 192.168.42.2 when traffic is destined to the 10.3.0.0/24 subnet.

    etc etc.

    If you have another remote subnet, you are right, you just add the extra line to the crypto-NAT and crypto-ACL. So, you will have the following lines:

    IP 10.8.1.0 allow Access-list crypto-NAT 255.255.255.0 10.3.0.0 255.255.255.0

    10.8.1.0 IP Access-list crypto-NAT 255.255.255.0 allow 10.5.0.0 255.255.0.0

    Crypto ip 192.168.42.0 access list ACL allow 255.255.255.0 10.3.0.0 255.255.255.0

    Crypto ip 192.168.42.0 access list ACL allow 255.255.255.0 10.5.0.0 255.255.0.0

  • VPN with NAT Interface

    Hello

    I am trying to set up a VPN between a VLAN I have defined and another office. I have been using nat on the interface for internet access with a NAT pool.

    I created the VPN with crypto card and the VPN is successfully registered.

    The problem I encounter is that with NAT is enabled, internet access is working but I can ping through the VPN.

    If I disable NAT, VPN works perfectly, but then him VLAN cannot access the internet.

    What should I do differently?

    Here is the config:

  • What is the function of the IOS minimum set required for VPN site-to-site software?

    Hi guys,.

    I have a Cisco 1841 router to do a VPN site-to site. I would like to know what is the function of the IOS minimum set required for VPN site-to-site software?

    Thanks in advance.

    Hi Ja,

    Advanced security or more should do it. The version of the IOS, you can try later 12.4 T which is c1841-advsecurityk9 - mz.124 - 24.T5.bin, in which case you don't want to go to 15.1 still.

    I hope this helps.
