• concentrator 3000 2 lan lan VPN with NAT

  I need to configure a vpn lan-2lan between 2 3030 concentrators (separate companies) on the Internet. My company assigns a small subnet for hosts sitting on the client network. The customer wants to use their own IP subnet and assign IP addresses within their range. So, they do static NAT on their hub. Is this possible? Or have they NAT s pc before arriving to the hub? Any help much appreciated.

  Hello

  Concentrator VPN supports the NAT.

• LAN to LAN VPN with NAT - solved!

  Hello world

  I have problems with a VPN L2L is implemented and logged, however when traffic comes from the other side of the tunnel it is not the host to internal network using a static NAT. Inside host 172.18.30.225 is current NATted to yyy.30.49.14 which is an IP address on the DMZ (yyy.30.49.0 255.255.255.240) Interface.

  Here is the configuration

  object-group network NET Tunnel
  network-host xxx.220.129.134 object

  Access tunnel list - extended ACL permit ip host yyy.30.49.14 object-group NET Tunnel

  correspondence address card crypto MAP_Tunnel 20 Tunnel-ACL

  the Tunnel-iServer-NAT object network

  network of the Tunnel and drop-in iServer object
  Home 172.18.30.225

  network of the Tunnel and drop-in iServer object

  The internal host does live on the network DMZ or internal? If she lives on the internal network, you can not NAT to the DMZ to interface and make it out of the external Interface, assuming that the external interface is the interface of VPN endpoint. If you terminate the VPN on the DMZ interface and the internal host lives on the internal network, then that's fine.

• Duplicate remote Lan VPN subnets

  Hello Experts,

  I have 2 lans DISTANCE double connection via VPN with the ip address of 192.168.70.X and 192.168.70.x

  We are already working, but I don't know how to add the second that is listed

  exactly the same thing. Not clear how to apply the NAT on my Local router for the second subnet duplicate.

  I found this article but he speaks of lans in double on both sides, and it does NOT

  http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a00800b07ed.shtml

  Is there something similar, but with 2 LAN REMOTE subnets?

  Thank you

  Randall

  Hi, Randall

  As far as I know, you will have to do it on the remote end. The problem is that if you have the same address for example 192.168.1.70 arriving from two sites on the same time on your side VPN device will get very confused as to where the return traffic should pass.

  You can NAT IP source on your local router to a set of addresses 192.168.70.x addresses, but I still think that the VPN device would not be able to determine what tunnel to send traffic down on the way back.

  I appreciate it is not always easy to get the 3rd party to do something, but I think that that's your only choice.

• VPN to access LAN VPN clinet.

  We use a PIX 515 as the hub of a LAN to LAN VPN as well as to access VPN Clinet. Using a multipoint configuration sites speaks (all PIX 501) are able to communicate with each other. However, the VPN to access the 515 client are not able to access the VPN sites has talked about. I think that it is due to the fact that put an end to all tunnels on the same interface of the PIX 515. Is there a way to allow the VPN CLient to communicate with the LAN VPN spoke?

  Concerning

  PD

  Currently, it is not a good way to meet the requirements above. However, add us a new item (or rather, a restriction of relax) for the PIX 7.0 code (to be released in December/January) to allow clients VPN packets 'u-turn' on a Hub PIX to PIX spoke connected via Lan-to-Lan tunnels. The program 7.0 beta is about to begin (may have just begun) so if interested, please contact your local account engineer Cisco. Sorry for the news but help is on the way.

• 3925, IPsec LAN - LAN VPN tunnel command unavailable

  Hello

  I am looking to use one of my 3925 to create a VPN IPsec LAN - LAN tunnel with another site.

  I was under the impression that I needed to get a license of securityk9 installed and then I was good to go.   I got a temporary license for 60 days and it is installed, but none of the commands I need to create the tunnel are appearing for me.

  I am using the command "crypto isakmp", but which does not appear:

  Router (config) #crypto?
  CA Certification Authority
  main activities key long-term
  public key PKI components

  Here's my license to show:

  Function index 2: securityk9
  Time left: 633 weeks 4 days
  Period of opportunity: 0 minute 0 second
  License type: assessment
  The license status: active, don't use, EULA accepted
  Number of licenses: not counted
  License priority: bass

  Don't know why there are so many weeks left

  Thoughts on that?

  Thanks in advance.

  just a little thing

  have you tried in config guest... . License to start and so on.

  as you said the router to use the license that you have installed.

  If you are a license sh what do you get?

  Good luck

• VPN Remote LAN to LAN VPN issues

  The issue I'm having is that I have an ASA that provides Lan to Lan VPN and remote access VPN.  Lan to Lan VPN connects to another network where a remote server, and the remote vpn connects remote users to the LAN.  The two virtual private networks are currently working, however users remote connection via the remote access vpn can not connect to the server over the lan to lan vpn.  Here's our Installer.

  ASA - LAN to LAN VPN - ASA - LAN Local - Server

  |

  |

  Remote VPN access

  |

  |

  Remote users

  In this configuration remote users can access the local network, the server can access the local network, and the local network can access the server and remote users.  However, the server cannot access the remote users and remote users cannot access the server.  Any ideas on how to get this to work would be much appreciated.  I created the NAT rules I think were needed and added the necessary address so that the user remote vpn' client application lists the network on the otherside of the vpn as routable network LAN to LAN.  Also, I believe that all the rules of access are correct as tracers of package on both sides are successful.  However when you try to ping across the remote client on the server at the other end of the L2L it fails as other attempts to access the server like rdp.  Does anyone have a step by step on how to set up this type of vpn configuration remote and l2l configured on asa while leaving the two virtual private networks talk to each other.  By the way are two ASA 5505 that with two virtual private networks in this configuration is one on the other end of the l2l 7.2 and 8.2.  Any help would be appreciated, especially a tuturail or a list of commands needed to implement, because I think that I'm probably missing just a little extra configuration, I just can not understand.

• Lan to lan VPN and VPNclient support at the same time?

  Hello I have a 2811 router.

  I put up as a VPN with Clients_vpn hub connect to it, and I used an IPSec on a stick configuration.

  At the same time, I would need to use the same Lan - to - Lan IPSec router to other different sites 2.

  I can't figure out how do it since I use already my 2811 as Concentrator VPN for Clients_vpn.

  Y at - it a trick?

  Thank you very much

• How to Segment LAN/WLAN with TimeCapsule and third party LAN

  Hello

  I have a bit of a delicate situation. I need to speed up my (W) LAN through segmentation and hope that many of you might be able to help here.

  Currently my TimeCapsule connects via its WAN for a FritzBox with DHCP port. 255.255.255.0 subnet / host 192.168.178.1 TC router is turned off (bridge mode). The TC creates a wireless network. The FritzBox connects to the ISP and a lot other customers outside the TimeCapsule.

  The first WLAN TimeCapsule is extended by a second TimeCapsule. A couple AppleTV and expresses the airport are connected in the scope wireless of the 2nd TimeCapsule but far out of reach for first time capsule. Apple network and FritzBox network clients need NOT communicate with each other. It will be even better if they were aware, because there are other AppleTV, printers, servers UPnP, stream movie, etc.

  Thus, the 2nd TimeCapsule acts as a 'bridge' for the internet.

  Now, I want to segment the LAN (W). The main reason is to reduce traffic. The two TimeCapsules to connect with a very low bandwidth, because there are a whole bunch of concrete between the two. Since then, there are a LOT of current traffic, customers and also the internet connection around my TimeCapsules is not responding to most of the time.

  Is it possible to segment the LAN (W) with my first TimeCapsule and create a LAN (W) dedicated?

  Thank you very much for your help!

  I think that you need good QoS or limitation if I read your message.

  Give me real numbers.

  What is the max download and upload becomes your Frtizbox? Many real world real... using ethernet for the Fritzy and anything else using the bandwidth.

  The first link to the TC1 on ethernet should be no problem... but the TC2 wireless link is probably give you mediocre results... and there is very little you can do about it... have you tried or considered using adapters EOP. (homeplug to the United States).

  If you take the link that will help you.

  Segment the network's not going help the problem that I see.

  What model is the Christopher? Is there a QoS limitation or even decent with the limitation of bandwidth?

  You can set IP alias or VLAN on that?

  What model is the TC?

• Using configuration for the 2nd link of lan to lan vpn

  Hello

  Successfully, I configured a connection of lan to lan vpn between two offices. I try to add another link to a 3rd office to my office at home, but have some difficulty. I have attached my setup and hope someone can help me solve my problem. Right now I have a working vpn to the 172.16.0.0/24 network and putting in place the link to 172.16.3.0/24 so. For the new vpn connection, I can ping the external interfaces, but can't ping anything in-house.

  Thanks for your time and help,

  There is a major mistake that's easy to fix. You have successfully created a second instance of the encryption card to create a VPN tunnel for the second site. But as currently configured two instances of the encryption card use the same access list:

  1 ipsec-isakmp crypto map clientmap

  match address 100

  5 ipsec-isakmp crypto map clientmap

  match address 100

  But each session/tunnel VPN needs its own access list. So, I suggest that you make the following changes:

  5 ipsec-isakmp crypto map clientmap

  match address 101

  no access list 100

  access-list 100 permit ip 192.168.0.0 0.0.0.255 172.16.0.0 0.0.0.255

  access-list 101 permit ip 192.168.0.0 0.0.0.255 172.16.3.0 0.0.0.255

  This provides a list of separate for each session/tunnel access and should solve this problem. Try it and tell us the result.

• How to set up a Lan to Lan VPN without using your external IP address?

  I have two 28 subnets A & B.

  My PIX and ASA outside interface addresses are both in A subnet.

  I am in the middle of a migration of the PIX to ASA and need to use the PIX outside of the address of the interface on the ASA for the last two remaining lan to lan VPN.

  I do like that because the sellers of these virtual private networks to connect to are huge dinosaurs IT and the aaages to get their sh * t tri... This means that I have to pass the IP address to my ASA, so I can't sentence have change for a new IP peer.

  I tried to figure out how to set a specific my counterpart VPN IP address but I can't figure out how...

  I even physically connected a second ethernet port and tried to give a similar IP in the same range, which it says it is not possible to have both outside the IP addresses on the same subnet.

  Hello

  It is not possible to have an IP address "secondary" on the physics/logic interface of a Cisco firewall.

  And as you've noticed, you cannot configure the same subnet on 2 different interface either.

  We are talking about such a large configuration that you want to just migrate from completely to the ASA PIX and make a switch during a maintenance window?

  Couldn't you just pass the ASAs 'outside' IP address address to that on the PIX and move the ASAs 'outside' of the PIX? Or not the ASAs "outside" IP address already some configured related to what makes this impossible?

• Is site to site VPN with sufficiently secure router?

  Hello

  I have a question about the site to site VPN with router.

  Internet <> router <> LAN

  If I have a VPN site-to-site configured on the router above with another site. I configured to block incoming Internet connections with the exception of VPN to access list. What are the risks of the LAN is exposed to threats from the Internet? Recommend that you put in a firewall between the router and the LAN, or replace the router with a firewall?

  Thank you

  Hi Amanda,.

  Assuming your L2L looks like this:

  LAN - router - INTERNET - Router_Remote - LAN

  |-------------------------------------------------------------------------------|

  L2L

  Traffic between the two local area networks is protected by the VPN tunnel. It is recommended to use the recommended security (strong encryption settings) to ensure that the encrypted traffic would not be compromised through the Internet.

  On the other hand, if you talk about outbound plaintext to the Internet, as when a user acceses google.com, then you just make out traffic, but never allow all incoming connections.

  If you want to protect your network with advanced security as a FW features, you can consider ZBF, which is the available in IOS Firewall/set function:

  Design of the area Guide of Application and firewall policies

  If you consider that this is not enough, check the ASA5500 series.

• How to bind a VPN (TX via VPN) with a sat (RX via DVB - S2) / Windows Vista Home Edition / Multiple dial conections

  I use a Windows Vista Home Edition on a laptop. The system connects to the Internet through a cellular router EDGE (via Ethernet) and receives the data by linking receiver DVB - S2 satellite broadband connected via a USB interface. The connection is through a VPN. Windows Vista loses the symbol of the "blue planet", as soon as the VPN connects. Authentication and connectivity is OK. DNS also works OK by the way VPN, with pointing to the VPN IP address 0.0.0.0.  The diagnosis indicates an error where Vista says that she finds multiple active dial connections. Y at - it a configuration option that allows me to bind the interface transmission (VPN) with return channel satellite?  The same software and configuration under Windows XP SP3 works OK.

• 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...
