• Cisco ASA Site to Site VPN IPSEC and NAT question

  Hi people,

  I have a question about the two Site to Site VPN IPSEC and NAT. basically what I want to achieve is to do the following:

  ASA2 is at HQ and ASA1 is a remote site. I have no problem setting a static static is a Site to IPSEC VPN between sites. Guests residing in 10.1.0.0/16 are able to communicate with hosts in 192.168.1.0/24, but what I want is to configure the NAT with IPSEC VPN for this host to 10.1.0.0/16 will communicate with hosts in 192.168.1.0/24 with translated addresses

  Just an example:

  N2 host (10.1.0.1/16) contacted N1 192.168.1.5 with destination host say 10.23.1.5 No 192.168.1.5 (notice the last byte is the same in the present case,.5)

  The translation still for the rest of the communication (host pings ip destination host 10.23.1.6 N3 N2 not 192.168.1.6 new last byte is the same)

  It sounds a bit confusing to me, but I've seen this type of configuration before when I worked for the supplier of managed services where we have given our customers (Ipsec Site to Site VPN with NAT, don't know how it was setup)

  Basically we contact the customer via site-to-site VPN hosts but their real address were hidden and we used as translated address more high 10.23.1.0/24 instead of (real) 192.168.1.0/24, last byte must be the same.

  Grateful if someone can shed some light on this subject.

  Hello

  OK so went with the old format of NAT configuration

  It seems to me that you could do the following:

  • Configure the ASA1 with static NAT strategy
    • access-list L2LVPN-POLICYNAT allowed ip 192.168.1.0 255.255.255.0 10.1.0.0 255.255.0.0
    • public static 10.23.1.0 (inside, outside) access-list L2LVPN-POLICYNAT
  • Because the above is a static NAT of the policy, this means that the translation will be made only when the destination network is 10.1.0.0/16
  • If you have for example a PAT basic configuration to inside-> external traffic, the above NAT configuration and the custom of the actual configuration of PAT interfere with eachother
  • ASA2 side, you can normally configure NAT0 / NAT Exemption for the 10.1.0.0/16 network
    • Note of the INTERIOR-SHEEP access-list SHEEP L2LVPN
    • the permitted INSIDE SHEEP 10.1.0.0 ip access list 255.255.0.0 10.23.1.0 255.255.255.0
    • NAT (inside) 0-list of access to the INTERIOR-SHEEP
  • You will need to consider that your access-list defining the VPN encrypted L2L traffic must reflect the new NAT network
    • ASA1: allowed to access-list L2LVPN-ENCRYPTIONDOMAIN ip 10.23.1.0 255.255.255.0 10.1.0.0 255.255.0.0
    • ASA2: list L2LVPN-ENCRYPTIONDOMAIN allowed ip 10.1.0.0 access 255.255.0.0 10.23.1.0 255.255.255.0

  I could test this configuration to work tomorrow but I would like to know if it works.

• IPSEC and NAT

  I have a client that uses NAT to connect to the web. He wants to connect to a server on the web using IPSEC. This server has a static NAT entry.

  I fear that, due to the NAT process sitting between the hosts that the IPSEC tunnel will not work.

  Please notify.

  Assuming you are using ESP encapsulation, static NAT should work. PAT will have problems and encapsulation AH will not work. You will also need to open a conduit for incoming ESP and IKE (UDP 500) on the firewall.

• Need help, a problem with IPSec and NAT - T

  We had a successful between a Cisco remote access client and the ASA connection.   The connection is more data transfer, but the Phase I and Phase II complete successfully.   There are several sections between separate networks for the remote user to the ASA, including hotlines of Verizon and Verizon's ISP.

  Troubleshooting Cisco guides strongly suggests, it is a problem of NAT - T, but when I turn on debugging 254 isakmp and debug ipsec 254, I get only a modest messages on NAT - T, which is "Recieved NAT-Traversal version 02 VID.   This message and connections, are when I disabled it on the ASA of NAT - T.

  If I enable NAT - T on the SAA, the remote client cannot establish Phase I or II; I was not able to gather debugs on this scenerio yet.

  The customer has a second laptop, both of them experience the same problem.  We have ensured that the Tunneling, UPD 4500 is activated.

  I suspect that an intermediary device or Verizon, changed something.

  What should be my next troubleshooting (unfortunately, I can't post the configs)?

  Kind regards

  j

  From my very limited experience, both sides must have the NAT - T enabled, otherwise the side who did not need NAT - t won't be able to read the part of the IP header because it is encrypted.

  Good luck!

  Hello

  I think that you need to configure the ACL default PAT so there first statemts 'decline' for traffic that is NOT supposed to be coordinated between the local network and VPN pool

  For example, to do this kind of configuration, ACL and NAT

  Note access-list 100 NAT0 customer VPN
  

  access-list 100 deny ip 10.0.1.0 0.0.0.255 10.88.0.0 0.0.0.255
  

  Note access-list 100 default PAT for Internet traffic
  

  access-list 100 permit ip 10.0.1.0 0.0.0.255 ay

  overload of IP nat inside source list 100 interface GigabitEthernet0/0

  
  EDIT: seem to actually you could have more than 10 networks behind the router

  Then you could modify the ACL on this

  Note access-list 100 NAT0 customer VPN
  

  access-list 100 deny ip 10.0.1.0 0.0.255.255 10.88.0.0 0.0.0.255
  

  Note access-list 100 default PAT for Internet traffic
  

  access-list 100 permit ip 10.0.1.0 0.0.255.255 ay

• VPN IPSec with no. - Nat and Nat - No.

  On a 6.3 (5) PIX 515 that I currently have an IPSec VPN configured with no. - nat, using all public IPs internally and on the remote control. Can I add two hosts to the field of encryption that have private IP addresses and NAT to the same public IP in the address card Crypto? What commands would be involved in this?

  Current config:

  -------

  ipsectraffic_boston list of allowed access host ip host PublicIP11 PublicIP1

  ipsectraffic_boston list of allowed access host ip host PublicIP22 PublicIP2

  outside2_outbound_nat0_acl list of allowed access host ip host PublicIP PublicIP

  card crypto mymap 305 correspondence address ipsectraffic_boston
  mymap 305 peer IPAdd crypto card game.
  mymap 305 transform-set ESP-3DES-SHA crypto card game
  life card crypto mymap 305 set security-association seconds 86400 4608000 kilobytes

  ---------

  I would add two IP private to the 'ipsectraffic_boston access-list' and have NAT to a public IP address, as the remote site asks that I don't use the private IP. This would save the effort to add a public IP address to my internal host.

  Thank you

  Dan

  Hello

  If for example you have an internal host 192.168.1.1 and you want NAT public IP 200.1.1.1 it address

  You can make a static NAT:

  (in, out) static 200.1.1.1 192.168.1.1

  And include the 200.1.1.1 in crypto ACL.

• Split of static traffic between the VPN and NAT

  Hi all

  We have a VPN from Site to Site that secures all traffic to and from 10.160.8.0/24 to/from 10.0.0.0/8.  It's for everything - including Internet traffic.  However, there is one exception (of course)...

  The part that I can't make it work is if traffic comes from the VPN (10.0.0.0/8) of 10.160.8.5 (on 80 or 443), then the return traffic must go back through the VPN.  BUT, if traffic 80 or 443 comes from anywhere else (Internet via X.X.X.X which translates to 10.160.8.5), so there need to be translated réécrirait Internet via Gig2.

  I have the following Setup (tried to have just the neccessarry lines)...

  interface GigabitEthernet2

  address IP Y.Y.Y.Y 255.255.255.0! the X.X.X.X and Y.Y.Y.Y are in the same subnet

  address IP X.X.X.X 255.255.255.0 secondary

  NAT outside IP

  allow an ip

  route No. - NAT allowed 10 map

  corresponds to the IP no. - NAT

  With the above configuration, we can get to the Internet 10.160.8.5, but cannot cross it over the VPN tunnel (from 10.200.0.0/16).  If I remove the two commands «ip nat inside source static...» ', then the opposite that happens - I can get then to 10.160.8.5 it VPN tunnel but I now can't get to it from the Internet.

  How can I get both?  It seems that when I hit the first NAT instruction (overload Gig2) that 'decline' in the list of ACL-NAT-outgoing punts me out of this statement of NAT.  It can process the following statement of NAT (one of the 'ip nat inside source static... ") but does not seem to"deny"it in the NON - NAT ACL me punt out of this statement of NAT.  That's my theory anyway (maybe something is happening?)

  If this work like that or I understand something correctly?  It's on a router Cisco's Cloud Services (CSR 1000v).

  Thank you!

  Your netmask is bad for your 10.0.0.0/8. I worry not about the port/protocol or since that can screw you up. A better way to do it would be to deny all IP vpn traffic.

  NAT-outgoing extended IP access list

  deny ip 10.160.8.0 0.0.0.0.255 10.0.0.0 0.255.255.255

  ...

  No. - NAT extended IP access list

  deny ip 10.160.8.0 0.0.0.0.255 10.0.0.0 0.255.255.255

  allow an ip

• VRF support IPsec with dynamic VTI

  http://www.Cisco.com/en/us/docs/iOS-XML/iOS/sec_conn_vpnips/configuration/15-2mt/sec-IPSec-virt-tunnl.html#GUID-C0A165BF-5866-4B13-BD73-0892B7E65488

  According to the example: "taking VRF support IPsec with a dynamic VTI when VRF is configured under year ISAKMP profile" I should be able to configure the features of the vrf and virtual-model under the same crypto isakmp policy.

  Unfortunalety, if I try to do, I get the following message

• Press L2L VPN, IPSEC, and L2TP PIX connections

  Hi all

  I'm trying to implement a solution on my FW PIX (pix804 - 24.bin) to be able to support a VPN L2L session with VPN dynamic user sessions where clients will use a mix of IPSEC(Nat detection) and L2TP. We have always supported things IPSEC and that worked great for many years. I'm now trying to Add L2TP support, so that I can support Android phones/ipads, etc. as well as Windows with built in VPN l2tp clients clients. Everything works well except for the new features of L2TP. Allows you to complete one phase but then tries to use the card encryption that is used for the VPN L2L. It seems to fail because IP addresses are not in the configured ACL to the crypto-map L2L. Does anyone know if there are any questions all these configurations support both. And if not can you see what I have wrong here, which would make it not work. Here are the relevant training:

  This seems to indicate that his NAT detection but then do not assign to the entry card cryptography because networks are encrypted are not in the configured ACL that is true. He needs to use dynamic input and it doesn't seem to be.

  I need to create another dynamic map entry to make it work instead of add lines to the same dynamic with a lower (higher) priority map entry?

  Thanks in advance for any help here.

  Hello

  That won't do the trick, l2tp clients are picky kindda, so you know if they do not hit the correct strategy first they just stop trying. Follow these steps:

  correspondence from the company of dynamic-map crypto-ras 1 address company-dynamic

  No crypto-card set pfs dynamic company-ras 1

  No crypto dynamic-map company-ras-1 transform-set ESP-SHA-3DES ESP-3DES-MD5 company-ras

  Dynamic crypto map company-ras 1 transform-set company-l2tp SHA-ESP-3DES ESP-3DES-MD5 company-ras

  The foregoing will not affect existing customers of IPsec at all, these clients will not use the statement of pfs and will link even if the correspondence address is not configured (it is optional), besides Cisco IPsec clients will be affected first the mode of transport policy and fail however they will continue to try and hit another police PH2.

  Regarding your last question, I was referring specifically to the support of l2tp for android, and Yes, you will need to run one of these versions.

• L2TP/IPSec and VRRP on Cisco VPN3000

  Hello. I don't know if this is the right forum, please excuse me if this is not (of course a pointer to the right we'd appreciate it :)

  I'm experimenting with the implementation of VPN 3000 Concentrator series VRRP, and it seems that when the unit of "backup" takes over, no L2TP/IPsec tunnel can be established more.

  When the switch takes place, the backup device takes over VRRP group IP addresses, which are the IP address of the master own as well on VPN 3000. Thus, the backup unit manages two different IP addresses, its own ad group.

  Well, what I observed using a sniffer is that while the IKE/IPSec packets come well to the group address, L2TP packets are by IP address of the backup device physical and clear instead of be encapsulated in IPSec travel packages. The client computer (PC Windows 2000) clearly ignores the L2TP packets and no L2TP/Ipsec tunnel can be established. PPTP tunnels work, however.

  The foregoing does not occur when the VPN 3000 master works, like the VRRP group addresses are the same as its own interface addresses.

  Now, VPN 3000 documentation or TAC documents explicitly say that L2TP/IPSec and VRRP are incompatible, but they do not mention compatibility as well (although they do mention the VRRP Protocol PPTP compatibility).

  Did someone better informed than me? Is there a technical reason for the incompatibility between L2TP with VRRP, or it's a bug any?

  Thank you

  Roberto Patriarca

  This has proved quite recently and a high severity bug has been open about it and is currently under review.

  See http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCeb77328&Submit=Search for more details.

  Nice work well in the survey.

• Windows IPSEC and SSL VPN client on the same machine

  Matches (coexistence) installation of IPSEC and SSL vpn clients that are supported on the same computer, windows (XP and Win7)?

  As mentioned by Patricia and Jennifer (5 stars), you can install two clients on the same machine without any problem.

  The tricky part comes when you are trying to connect two clients at the same time, that's when you may encounter unexpected problems.

  However, if your intention is to install both clients and connect them individually and not at the same time, you'll be fine.

  If you have any other questions, please mark this question as answered and note all messages that you have found useful.

  Thank you.

• CS4 Content Aware Fill and Lasso tool

  I seen this interpreted by Moose Petersen to duplicate

  and fill an area to enlarge an image. He has used the Lasso tool to frame (currently vacant) area he wanted to fill it with the exact content on the edge of the image.

  I was unable to rebuild its process.

  A person can offer aid step by step to achieve this? You want to fill the right side so that size 16 x 20.

  Thank you!

  Dan

  Here, I'll be a little more specific.  Do things in exactly in this order:

  > 1. Make the image a layer (no background).

  To do this, make the visible LAYERS Panel, hold the ALT key and double-click on the background.  It should become the layer 0.  If it is not to start from the bottom, you can skip this step.

  

  > 2. Increase the size of the canvas to the ratio 16 x 20, opening new space on the right.

  Image - Image size, uncheck resampling and make the image 20 inches in height.  Then choose a picture - size of the canvas, and then to the right as follows:

  

  

  > 3. Make a rectangular selection, excluding most of the Red parts.

  You should have, at this stage, an image with a grid showing on the right side.  Choose the Rectangle tool, as I indicated in the post above 5 and drag around the area shown in post 1, including some of the red pieces.

  > 4. Edit - Content Aware scale and drag the right handle to fill the drawing area.

  Click on Edit - Content Aware scale in the menu.  You will get a set of small handles square around the portion of the image you selected.  Take the right and pull to the right, as shown here:

  

  > 5. Editing (for example, slightly fuzzy) edges that have become noisy because of the operation.

  After the operation of Content Aware scale, I saw that the flower petal edge was a bit rough looking, so I thought it would be a good idea to choose the tool blur and brush on the edge slightly.

• VTI and NAT IPsec Tunnel mode

  Hello world

  I don't know that this subject has been beaten to death already on these forums.  Nevertheless, I have yet to find the exact solution, I need.  I have three machines, two routers and an ASA.  One of the routers sits behind the ASA and I have a GRE VTI configuration between two routers with ASA NATting, one of the routers to a public IP address.  I can guarantee the tunnel mode IPsec transport, but as soon as I pass in tunnel mode, the communication fails even if the SA is established.

  Please see the configuration below and tell me what I am missing please.  I changed the IP addresses for security.

  The following configuration works when transform-set is set to the mode of transport

  Note: The Router 2 is sitting behind the ASA and is coordinated to the public IP 200.1.1.2

  Router 1:

  Crypto ipsec transform-set SEC esp - aes 256 esp-md5-hmac

  There is no access-lists on the SAA except to allow a whole ICMP

  I am very grateful for any guidance you can provide in advance guys.

  Hello

  MTU, and the overhead was in this case.

  You changed encapsulating ipv4 instead of LIKING - which have less overhead (no GRE inside). This is why it started working.

  If you want to continue using GRE you decrease the MTU as described.
