  Would appreciate any help you can provide.

  The phase 2 does not complete since there is no visible SPI value. In addition, depending on your configuration Transport mode is configured for phase 2 However, debug displays the tunnel mode.

  Thus, as suggested earlier to debug this further and find the root cause we need to match the configuration settings in Phase 2 with regard to the remote device.

  Hope that helps.

  Kind regards

• VPN IPSec in LAN-2LAN tunnel configuration

  Hi all!!

  I'll put up a tunnel between a cisco 1841 router and a VPN 3000 Concentrator LAN LAN 2 ipsec.

  Thank you very much in advance for your help

  Glenn

  Thanks for the configuration.

  So you're natting and then to encrypt traffic natted. Which is totally fine. The reason, your ping does not work after the application of cryptography is due to the ACL entries below:

  access-list 101 permit icmp any any echo

  access-list 101 permit icmp any any echo response

  The acl entries above are part of the traffic interesting Crypto. So once you apply the card encryption the router is supposed to encrypt all ICMP Echo and Echo-Reply, including traffic that is presented with the ip address of your 201.x.x.x. If you remove these two entries of the ACL 101 and apply only the below entries, then the ICMP should work with the applied crypto map.

  access-list 101 permit ip 172.4.4.0 0.0.0.255 172.17.0.64 0.0.0.7

  access-list 101 permit tcp host 172.4.4.5 host 172.17.0.65 eq 1000

  access-list 101 permit udp host 172.4.4.5 host 172.17.0.65 eq 1000

  After making the changes, make sure that crypto acl is images mirror on VPN3000 and router, or otherwise you will have problems in the implementation of the tunnel.

  I would like to know how the test goes without the ACL 101 ICMP entries.

  Kind regards

• Failed to configure two AnyConnect & IPSEC site to site VPN

  I have established a VPN IPSEC site-to-site

  When I configure the AnyConnect (make it work) and I lose the tunnel from site to site and vice versa.

  I think that my NAT syatements are incorrect.

  Here is the config NAT when AnyConnect works properly...

  Overall (101 outside interface)
  NAT (inside) 0-list of access sslnonat
  NAT (inside) 101 0.0.0.0 0.0.0.0

  access extensive list ip 192.168.65.0 sslnonat allow 255.255.255.0 192.168.66.0 255.255.255.0

  When the IPSEC tunnel site-to-site work properly, here's the NAT config...

  Overall (101 outside interface)
  NAT (inside) 0-list of access Inside_nat0_outbound
  NAT (inside) 101 0.0.0.0 0.0.0.0

  Access extensive list ip 192.168.65.0 Inside_nat0_outbound allow 255.255.255.0 ServerGroup object-group

  How do I get to the AnyConnect and the IPSEC Site to site both to work properly? I need not reach on the other.

  Network within 192.168.65.0/24

  AnyCOnnect address pool 192.168.66.0/24

  Any help would be appreciated.

  Hello

  Try this:

  Overall (101 outside interface)
  NAT (inside) 0-list of access Inside_nat0_outbound
  NAT (inside) 101 0.0.0.0 0.0.0.0

  Access extensive list ip 192.168.65.0 Inside_nat0_outbound allow 255.255.255.0 ServerGroup object-group
  Access extensive list ip 192.168.65.0 Inside_nat0_outbound allow 255.255.255.0 192.168.66.0 255.255.255.0

  The problem is that when you apply the IPsec NAT configuration, you remove the entry for the AnyConnect pool.
  Try the above and we will see if it works.

• 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.

• ASA ASA from Site to Site VPN IPSec Tunnel

  Any help would be greatly appreciated...

  I have two devices Cisco ASA with a Site for the configuration of the tunnel VPN IPSec Site as follows: -.

  Site #1 - Cisco ASA running version 8.2 (1) with an internal range of 10.0.0.x/24

  Site #2 - Cisco ASA running version 8.2 (1) with an internal range of 10.1.1.x/24

  Site #1 is simple and has a dynamic NAT rule which translates all of the inside and the outside (public IP) of the SAA.

  Internet access works very well in all workstations of this site.  A static route is configured to redirect all traffic to a public router upstream.

  Site #2 is slightly more complicated; the Cisco ASA is configured with 10.1.1.254/24 as its interior IP address and 10.1.2.254/24 as its external IP address.  A dynamic NAT rule is configured to translate everything inside as the 10.1.2.254 (outside) address of the ASA.  A default static route is then configured to redirect all traffic to a Draytek device on 10.1.2.253.  This device then performs its own private Public NAT.  Again the Internet works fine all hosts inside the Cisco ASA (10.1.1.x)

  The IPSec tunnel is created with the networks local and remote endpoint as above (10.0.0.x/24) and (10.1.1.x/24).  The Draytek at the Site #2 device is configured with a form of DMZ that allows essentially ALL traffic toward the front directly on the external interface of the ASA (10.1.2.254).  The Phase 1 and Phase 2 negotiation of the tunnel ends correctly, and the tunnel is formed without any problem.  However, all traffic passing on networks ICMP does not end and the Syslog reports the following-

  It's the same for any form of traffic passing over the tunnel.  The ACL is configured to allow segments of LAN out to any destination.  At this point, I left scratching my head, as my original theory was to blame the Draytek, but after reading the documentation given to the DMZ host configuration, it appears this parameter is configured all traffic is simply forwarded to the IP address (in this case, the Cisco ASA interface outside).

  Anyone can shed light on a possible cause of this problem?

  Thank you

  Nick

  did you bypass the vpn traffic between 10.0.0 and 10.1.1 to be NAT - ed on the two ASA?

  Please provide the following information

  -set up the tunnel

  -show the isa cry his

  -show the ipsec cry his

  -ping of the site 1 site 2 via tunnel

  -capture "crypto ipsec to show his" once again

  -ping from site 2 to 1 by the tunnel of the site

  -capture "crypto ipsec to show his" once again

  on pix not sure of the syntax, I think it is

  Permitted connection ipsec sysopt

• 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:

  Hope this info helps!

• 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),

  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.

• 887VDSL2 IPSec site to site vpn does NOT use the easy vpn

  Much of community support.

  as I'm looking through the config Guide about 870 router series, only to find information about the config with eazy vpn.

  is there a classic way, about 870 Series site 2 site without eazy vpn IPSec configuration?

  Have a classic way if a tunnel? Have the 870 is not as a vpn client?

  Thank you

  Of course, here's example of Site to Site VPN configuration for your reference:

• IPSec site to site VPN cisco VPN client routing problem and

  Hello

  I'm really stuck with the configuration of ipsec site to site vpn (hub to spoke, multiple rays) with cisco vpn remote client access to this vpn.

  The problem is with remote access - cisco vpn client access - I can communicate with hub lan - but I need also communication of all lans speaks of the cisco vpn client.

  There are on the shelves, there is no material used cisco - routers DLINK.

  Someone told me that it is possible to use NAT to translate remote access IP-lan-HUB customers and thus allow communication - but I'm unable to set up and operate.

  Can someone help me please?

  Thank you

  How the DLINK has been configured for traffic between the site to site VPN subnets? You are able to add multiple remote subnets on DLINK? If you can, then you must add the pool of Client VPN subnet.

  Alternatively, if you cannot add multiple subnet on DLINK router, you can change the pool of Client VPN 192.168.6.0/24, and on the crypto ACL between the site to site VPN, you must edit the 180 existing ACL

  DE:

  access-list 180 allow ip 192.168.7.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 180 allow ip 192.168.200.0 0.0.0.255 192.168.1.0 0.0.0.255

  TO:

  access-list 180 allow ip 192.168.6.0 0.0.1.255 192.168.1.0 0.0.0.255

  Also change the ACL 190 split tunnel:

  DE:

  access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.200.0 0.0.0.255

  access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.200.0 0.0.0.255

  TO:

  access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.6.0 0.0.0.255

  access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.6.0 0.0.0.255

  Finally, replace the remote subnet 192.168.7.0/255.255.255.0 192.168.6.0/255.255.254.0 DLINK.

  Hope that helps.

• Site-to-Site VPN IPSEC falls intermittently

  Site-to-Site VPN IPSEC falls intermittently

  I am currently having a problem with a VPN from Site to Site traffic not only not intermittently. When the problem occurs, I can't Ping the remote site to the AC Site. But I can solve the problem by Pinging from HQ at the Remote Site. My network is currently configured as follows

  -------HQ------

  7.0 (4) version of pix 515 with card Ethernet 4 ports.

  Outside of the interface connected to the Broadband DSL link.

  Outside2 Interface connected to the second link DSL broadband

  -Distance-

  I have 4 Remote Sites. 2 sites connect you to each connection to wide band at HQ to spread the load to HQ

  6.3 (5) pix 501 version

  # The problem #.

  All VPN establishes successfully to the HQ Pix

  Intermittently, a remote site will report that they cannot connect to servers/services in the HQ. When I do a show crypto ipsec's and see the crypto isakmp his headquarters there is no entry for the remote site. However when I do the same on the remote site there is an entry for the HQ. With debugging on the remote site pix I try to ping from a pc to the HQ server and I get the following (see below). If I do a "ipsec Isakmp security association claire crypto ' and ' clear crypto ipsec his ' on the pix of remote site, then I can successfully ping all servers in headquarters.

  This problem seems to have taken place only when I upgraded the pix of a 501 to 515 and added another 2 remote sites and a second broadband, as described above. I'm afraid that there is a problem with software version 7 Pix. Any advice would be greatly appreciated.

• IPsec Site to Site VPN multisession?

  Hi people.

  I recently faced a problem at work. Customers want to dismiss ipsec site to site vpn. I have 2 asa 5520 working in a stack. Is it possible to configure the vpn site to site in a redundant mode, as the first ip address is x.x.x.x and secondary is y.y.y.y (backup)?

  Thank you much in advance.

  Hello

  You can define several counterparts in the card encryption, see:

  http://www.Cisco.com/en/us/docs/security/ASA/asa72/command/reference/c5_72.html#wp2066090

  You can define several tunnels and leave the routing protocol to choose the best route.

  Hope this helps,

  Bastien.

• IPSEC VPN from Site to Site - NAT problem with address management

  Hi all

  I have two Cisco ASA 5505 performing of IPSEC Site to Site VPN. All traffic inside each firewall through the VPN tunnel and I have full connectivity. From site A, I can connect to the inside address of the ASA at the site B and launch of the ASDM or SSH, etc.

  The problem I have is when I'm logged on the ASA site B management traffic is given the external address. I created this as interesting traffic to get it to go through the VPN but I need to use the inside address of ASA B. The following is possible:

  • If I can make the ASA Site B to use inside interface as its address management (I already have management access to the inside Interface)
  • I have NAT can address external interfaces to Site B before moving through the VPN tunnel management traffic so that it appears to come from Site B inside the address
  • I can NAT VPN traffic as it appears in the Site A for management traffic to Site B on the right address.

  The problem is that my PRACTICE Please also come from this address and I need the application before being on an internal address to even if my CA.

  Thanks for any help.

  Ian

  Thanks, I understand what you are trying to achieve now.

  However, I think that I don't have good news for you. Unfortunately PEIE request can be initiated of the SAA within the interface, as there is no option to start the query from the inside interface. With other features of management such as AAA, logging, you have an option to specify what ASA desired originally to demand from interface, but CEP doesn't have this option.

  Here's how you can configure under the trustpoint crypto, but unfortunately by specifying the interface doesn't not part of option:

• 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.

  See you soon!
