• Design site to Site VPN w/NAT traversal issue

  Hi, I have a number of site to site VPN that end on a PIX. I intend to migrate these VPN to a router that sits on a demilitarized zone connected to the PIX. Before doing that I'm going to set up a private network new virtual to end on the router but I also need than VPNS that end on the PIX to be not affected.

  If I configure NAT traversal on the PIX, affected my other VPN?

  Thanks in advance

  DOM

  Hi Dom,

  Why do you want to configure NAT-Traversal on PIX, if you wish to terminate your VPN router (which is on the DMZ).

  Do you do any NAT on PIX thru the router?

  If you want to configure NAT-Traversal, it must be configured on the end (on the router in your case) devices.

  Example:

  When a user with Cisco client or Cisco router behind NAT wants to connect to another device (such as PIX, ASA, or router) NAT - T must be configured on the machine (which will be the PIX or ASA)

  Hope that helps.

• Site to Site VPN IPsec IPv6 on issue of routers-Tunnel

  Hi, I am experiencing a problem can any one address the question below and let me know the solution. I have two routers and try to build "Site to Site VPN IPsec IPv6". I followed orders from Cisco and community document but when I apply my profile of ipsec for tunnel interfaces, that the tunnel is down.

  https://supportforums.Cisco.com/docs/doc-27009

  Ali,

  VTI tunnels are meant to be broken when there is no active negotiated spinnakers.

  The tunnel will go towards up/face upwards when there is a means of transport of packages - i.e. the SPIs are present.

  You can control the order spinnakers 'show peer's crypto ipsec '.

  For debugging:

  Debug crypto isa

• question links to site 2 site VPN with authentication cert

  Currently we are accumulate tunnel site-2-site VPN with our client. Usually we use pre-shared key as authentication with other customers without any problems, but it must use authentication cert with her this time. But the question is that our CA is different from theirs. I tried a few times, but he failed. Is it someone please let me know that he must have the certificate issued by the same certification authority to create the VPN tunnel?

  Thank you very much!

  Hello

  You can read this document to get a simple example of setting up a VPN S2S using certificates on an ASA:

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080aa5be1.shtml

  Basically the sides must have the same certification authority and If there is an intermediate certificate that must be installed also. The ASA 2 will generate a CSR (certificate access code request), now then PKI will create a certificate for both parties, commonly called "certificate of identity".

  Please pass a note and mark as he corrected the post helpful!

  David Castro,

  Hello

  On router R1, you gave the default route as output interface. Instead of using the output interface replace the IP address of the next hop. It will solve the issue of the reduction of ping.

  IP route 0.0.0.0 0.0.0.0 FastEthernet0/0

  IP route 0.0.0.0 0.0.0.0 100.100.100.1

• Multi-site VPN problem

  Greetings,

  I practice implementation of VPN and it seems to have fallen on a small issue that solution eludes me.  Everything works in my current topology with the exception of a multi-site vpn.  I have 3 ASA, which is outside the interface is connected via a switch.  The inside interface is connected to a local area network that contains a workstation on each subnet.  I'm trying to set up a solution where I can have all 3 ASA related between them via a VPN.  The question I have is when I raise a single tunnel, scathing from a workstation behind the ASA, I can't set up a second tunnel scathing from a different network.  To explain that better, here is an explanation:

  ASA #1

  outdoors: 10.0.1.1/24

  inside: 192.168.0.1/24

  workstation: 192.168.0.100

  ASA #2

  outside: 10.0.1.2/24

  inside: 192.168.1.1/24

  workstation: 192.168.1.100

  ASA #3

  outside: 10.0.1.3/24

  inside: 192.168.2.1/24

  workstation: 192.168.2.100

  If I ping 192.168.0.100 192.168.1.100, the tunnel opens very well and I get answers.  If I can try and ping 192.168.0.100 192.168.2.100, does not open the tunnel to 192.168.2.0.  If I clear all its on ASA #1 and then ping 192.168.0.100 192.168.2.100, the tunnel opens very well and I get a response.  Then I try and ping 192.168.0.100 192.168.1.100 and the same thing happens, no tunnel and no response.  When I enabled logging on ASA #1 seems that it sends the ping for the different network on the tunnel open instead of opening a new tunnel to the correct network.  Can someone tell me what is happening here and if I just missed something simple with routing?  Or is it maybe a problem with VPN?

  Craig,

  You have default route badly configured on all the ASA. Here's what you have configured

  ASA1

  Route outside 0.0.0.0 0.0.0.0 192.168.0.1 1

  It's sendning the package for outside inside IP address. Here's what you need to do on the ASA

  ASA1

  No route outside 0.0.0.0 0.0.0.0 192.168.0.1 1

  Route outside 0.0.0.0 0.0.0.0 10.0.1.2

  ASA2

  No route outside 0.0.0.0 0.0.0.0 192.168.1.1 1

  Route outside 0.0.0.0 0.0.0.0 10.0.1.1

  ASA3

  No route outside 0.0.0.0 0.0.0.0 192.168.2.1 1

  Route outside 0.0.0.0 0.0.0.0 10.0.1.1

  Also delete icmp access list crypto that you allowed to what IP is the same access list. IP covers both the ICMP.

  Kindly let me know change default allows traffic.

  Kind regards

• IPsec site to Site VPN on Wi - Fi router

  Hello!

  Can someone tell me if there is a router Netgear Wi - Fi that can form IPsec Site to Site VPN connection between 2 Wi - Fi routers via the WAN connection?

  I know that this feature exists on the Netgear firewall, but can you have the same function on any Wi - Fi router?

  See you soon!

  I suspect that.

  Thank you very much for the reply.

• Site to site VPN, I need all internet traffic to exit the site.

  I have 2 sites connected via a pair of SRX5308

  A = 192.168.1.0/24

  IP WAN = 1.1.1.1

  B = 192.168.2.0/24

  IP WAN = 2.2.2.2

  Now what I need to do, is to have all traffic from B to go to the site one even traffic destined to the internet. That is, I need internet traffic out of our network with the IP 1.1.1.1, even if it is from the network B.

  On my I have set up a route 1.1.1.1 of the ISP, then a value by default 0/0 to 192.168.1.1 it ASA knows how to get to the peer VPN is a more specific route, but sends everything above the tunnel, at the remote end which then hairpin of ASA routes internet outside its own WAN port traffic.

  I can understand though not how to so the same thing on the pair of SRX5308 they either don't raise the tunnel or internet route to the local site address B.

  Anyone have any ideas?

  I need to do this because we are logging and monitoring of internet traffic to A site via tapping from upstream to various IDS solutions and will not (cannot) reproduce this to all our remote sites.

  Thank you

  Dave.

  After some more thought and testing I came up with a workable solution to my own problem. I'll share it here in case it can help others.

  (1) use the wizard at both ends to implement a normal VPN that connects the two segments of network 192.168.1.0 and 192.168.2.0

  (2) go to site VPN - VPN policy remote router192.168.2.1 and click Edit

  (a) disable Netbios

  (b) select "None" from the drop-down list the remote IP address.

  (c) to apply the change

  3) go to the VPN-> VPN policy on the head end site (192.168.1.1) and click Edit

  (a) disable Netbios

  (b) select "None" from the drop-down list the local IP address

  (c) to apply the change

  Now all the traffic wil go down the VPN tunnel and exit to the internet on the site of head end. Hope this helps others with the same question.

• Site to Site VPN on AZURE

  I have a VPN site-to-site existing on Azure and Azure a new subnet created on the local network that must be able to reach.

  I added the new subnet within azure for the VPN and add a static route on the RRAS server win 2012 for routing.

  On the initial installation of a RRAS-Site VPN site (I didn't configure it) I think the interesting traffic specified must be sent through the VPN Tunnel, but I knew how to specify the new subnet via RRAS, I don't want to delete and re-create the VPN Site to Site.

  Y at - there anyone who can help please.

  Thank you

• IPSec Site to Site VPN Solution needed?

  Hi all

  I need a solution to provide full connectivity to one of my clients. I created two IPSEC Site to Site VPN, one between the INFO and RITA and second between NIDA and RITA. I can access RITA machine that is 172.16.36.101 at the INFO and 10.0.0.5 to NIDA.

  Now, I need to give access to my customer INFORMATION to direct NIDA 10.0.0.5 without established VPN machine to NIDA 10.0.0.5 of 172.16.36.101 access.

  Could you please give me the solution how is that possible?

  Concerning

  Uzair Hussain

  Hi uzair.infotech,

  Looks like you need to set up a grouping between the 3 sites, at the end of that your topology will look like this:

  INFO - RITA - NIDA

  You can check this guide that explains step by step how to configure grouping:

• Troubleshooting IPSec Site to Site VPN between ASA and 1841

  Hi all

  in the past I've implemented several VPN connections between the devices of the SAA. So I thought a site link between an ASA site and 1841 would be easier... But it seems I was mistaken.

  I configured a VPN Site to Site, as it has been described in the Document ID: SDM 110198: IPsec Site to Site VPN between ASA/PIX and an example of IOS Router Configuration (I have not used SDM but CCP).

  I have run the wizards on the ASA with ASDM and the current IOS version 15.1 1841, with CCP.

  It seems to Phase 1 and 2 are coming although my ASA in ADSM reports (monitoring > VPN > VPN statistics > Sessions) a tunnel established with some of the Tx traffic but 0 Rx traffic),

  On the ASA:

  It seems that the routing on the 1841 is working properly as I can tear down the tunnel and relaunch in scathing a host on the network of 1841, but not vice versa.

  Trounleshoot VPN of the 1841 report shows a message like "the following sources are forwarded through the interface card crypto.      (172.20.2.0 1) go to "Configure-> routing" and correct the routing table.

  I have not found an error on the 1841 config so if one of the guys reading this thread has an idea I appreciate highly suspicion!

  It's the running of the 1841 configuration

  Joerg,

  ASA receives not all VPN packages because IOS does not send anything.

  Try to send packets to the 1841 LAN to LAN of the ASA and see is the "sh cry ips its" on the 1841 increments the encrypted packets (there not)

  The problem seems so on the side of the router.

  I think that is a routing problem, but you only have one default gateway (no other channels on the router).

  The ACL 100 is set to encrypt the traffic between the two subnets.

  It seems that the ACL 101 is also bypassing NAT for VPN traffic.

  Follow these steps:

  Try running traffic of LAN router inside IP (source of ping 192.168.37.x 172.20.2.254) and see if the packages are not through the translation and obtaining encrypted.

  I would also like to delete 100 ACL from the inside interface on the router because it is used for the VPN. You can create an another ACL to apply to the interface.

  Federico.
