• LAN-to-LAN tunnel between VPN 3000 and Cisco 1721

  Hello

  I have a current LAN-to-LAN tunnel configuration between VPN 3000 (3.6) and Cisco 1721 (12.2 (11) T).

  When I use the encryption = authentication and Des-56 = ESP\MD5\HMAC-128 for the IPSec Security Association, everything works fine.

  However, I would like to Turn off encryption for some time getting the speed improvements, so I changed

  Encryption = null esp (in 1721) and to "null" in VPN-3000.

  Now the tunnel is setup but I can spend only ICMP traffic. When I pass the traffic UDP\TCP the message below appears the Cisco 1721

  % C1700_EM-1-ERROR: error in packet-rx: pad size error, id 75, hen offset 0

  Has anyone seen this behavior?

  All those put in place an IPSec Tunnel with only the ESP authentication and NO encryption between VPN-3000 and Cisco 1721?

  Thanx------Naman

  Naman,

  Disable you the vpn Accelerator? "no accel crypto engine. Sure that you can't do with a null module vpn.

• VPN tunnel between 2 ASA 5505 with the same default gateway

  Hello

  Is it possible to create a vpn ipsec site to site (laboratory environment) between two 5505 (ASA IOS 8.2 (5) & asdm-645-206) with the same default gateway. That is a VPN tunnel or a back to back-to-one site that I have to deploy a router and hang each 5505 out a different interface? We have a lot of public IP but only one gateway our ISP (Internet). Any suggestions or recommendations are very appeciated!

  d

  Yes - you can even do it with a xover cable and a 30 ip on both external interfaces.

• Site to Site VPN tunnel between two ASA

  I use the Site Wizard to Site on an ASA 5520, and ASA 5505 of the ADSM. Both are using 8.4 (5). When you create configurations. You follow the wizard configurations with manual what ACL s to allow the traffic of every subnet connected to talk to each other? Or they are automatically generated in the configuration file? Have not been to school yet to understand how to create the CLI VPN tunnels and what to look for.

  Thank you

  Carlos

  Hello

  First, I would like to say that I don't personally use ASDM for the configuration.

  But you should be able to configure all the necessary elements for a connection VPN L2L base through the wizard.

  I guess that typical problems to do so could relate to the lack of configuration NAT exempt or might not choose the setting "Bypass Interface Access List" that would mean you would allow traffic from the remote site in the 'external' ACL of ASA local interface. Like all other traffic coming from behind the 'outer' interface

  If you share format CLI configurations and say what networks must be able to connect via VPN L2L then I could give the required CLI format configurations.

• Problem with Tunnel VPN L2L between 2 ASA´s

  Hi guys,.

  I have some problems with my VPN Site to site tunnel between 2 ASA (5520/5505).

  I watched a lot of videos on youtube, but I can't find out why the tunnel does not...

  Both devices can ping eachothers WAN IP address (outside interfaces), but I don't see any traffic between the 2 sites. It seems that the tunnel is not open to everyone. When i PING from the local to the Remote LAN (which should be an interesting traffic for the tunnel...), the its IKEv1 remains empty...

  Am I missing something? I can't understand it more why same phase 1 is not engaged.

  You NAT won't. In your config file traffic is NATted initially and then does not match any more crypto ACL. You must move the rule dynamic NAT/PAT until the end of the table on two ASAs NAT:

   no nat (INSIDE,OUTSIDE) source dynamic any interface nat (INSIDE,OUTSIDE) after-auto source dynamic any interface

• IPSec Tunnel permanent between two ASA

  Hello

  I configured a VPN IPSec tunnel between two ASA 5505 firewall. I want to assure you as the IPSec tunnel (this is why the security association) is permanent and do not drop due to the idle state.

  What should I do?

  Thanks for any help

  Disables keepalive IKE processing, which is enabled by default.

  (config) #tunnel - 10.165.205.222 group ipsec-attributes

  KeepAlive (ipsec-tunnel-config) #isakmp disable

  Set a maximum time for VPN connections with the command of vpn-session-timeout in group policy configuration mode or username configuration mode:

• IPSec tunnels between duplicate LAN subnets

  Hi all

  Please help to connect three sites with our Central site has all the resources for users, including internet access.

  The three sites will be the ASA 5505 like their WAN device.

  We need to know is - it possible, allowing to configure an IPsec Tunnel between the three ASA with duplicate LAN subnets.

  Central site two networks 192.168.1.x 24, 192.168.100.x 24

  Distance a 24 192.168.1.x subnet

  Two remote a subnet 192.168.100.x 24

  If it is possible we also do hair distance one ping, above two remote to the Central Site to access internet, what sites need are on the Central Site, including e-mail, network, other resource also records.

  We have no other way to make this network, as all security is on our Central Site, website filtering, Application filtering, filtering of network traffic all.

  We understand that we can change two remote sites to a different subnet from the Central Site, but we have so many host devices, it will take weeks or months, so to change the MS AD domain for all users, servers too.

  We really need your expertise to do this in a laboratory and then in production.

  Thank you

  Hello Stephen,

  You can check the following links for the subnets overlap talk to each other:-

  http://www.Cisco.com/en/us/products/ps5855/products_configuration_example09186a0080a0ece4.shtml

  Important point is local network must connect to the remote network via the translated addresses.

  for example, you won't be ablt to use real IP of the communication.

• Help with a VPN tunnel between ASA 5510 and Juniper SSG20

  Hello

  We have a customer wanting to configure a VPN Site to Site tunnel between a new purchased 5510 of ASA located in his direction with its Juniper SSG20 Office, located in the main office. We contacted HP and they send us a Cisco professional to do the job.

  After 2 days from 16:00 to 22:00 and error and countless hours of research online and nunerous calls, we are still unable to get traffic from the network of agencies to enter the tunnel.

  Main branch
  1.1.1.2                                 1.1.1.1
  -----                                               -----------
  192.168.8.0/24 | ASA|-----------------------------------| Juniper |    192.168.1.0/24
  -----                                               -----------
  192.168.8.254 192.168.1.254

  According to Cisco professionals, the tunnel is now in place but no traffic through. We are unable to ping anything on the network on the other side (192.168.1.0/24). We receive timeout ping all the time. The Cisco professional told us it's a routing or NAT problem and he's working on a solution!

  Through research, I came across a post on Experts-Exchange (here) [the 1st comment on the original post] which States "...". that both sides of the VPN must have a different class of LAN for the VPN to work... " Would that be our problem?

  It has become a critical issue to the point that he had to replace the Cisco ASA with a temporary Juniper SSG5 on another subnet (192.168.7.0/24) to get the tunnel upward and through traffic until the ASA VPN issue is resolved and I didn't need to say that the client is killing us!

  Help is very appreciated.

  Thank you

  1. Yes, ping package from the interface of the ASA is considered valuable traffic to the LAN of Juniper.

  SAA, need you traffic from the interface source ASA's private, because interesting to determine by crypto ACL MYLIST traffic between 192.168.8.0/24 and 192.168.1.0/24.

  You will also need to add the following configuration to be able to get the ping of the interface of the ASA:

  management-private access

  To initiate the ping of the private interface ASA:

  ping 192.168.1.254 private

  2. the default time before the next generation of new key is normally 28800 seconds, and if there is no interesting traffic flowing between 2 subnets, he'll tear the VPN tunnel down. As soon as there is interesting traffic, the VPN tunnel will be built automatically into the next generation of new key. However, if there is traffic before generating a new key, the new tunnel will be established, and VPN tunnel will remain standing and continue encrypt and decrypt traffic.

  Currently, your configuration has been defined with ITS lifetime of 3600 seconds GOLD / 4608000 kilobytes of traffic before the next generate a new key (it will be either 3600 seconds, or 4608000 kilobytes period expires first). You can certainly change it by default to 28800 seconds without configuring kilobytes. SA life is negotiated between the ASA and Juniper, and whatever is the lowest value will be used.

  Hope that helps.

• How can I request an ACL to a LAN-to-LAN tunnel?

  I have an ASA with an active IPSec LAN-to-LAN tunnel and I'm wanting to limit which ports and IPs my extranet partner is able to reach. How can I apply an ACL to a tunnel of LAN-to-LAN to restrict entry and exit through the tunnel?

  Thanks in advance!

  It will work the same way. You must use VPN filters. If you use 8.0, you can use the following doc:

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/products_configuration_example09186a00808c9a87.shtml

• Use the client VPN tunnel to cross the LAN-to-LAN tunnel

  I have been troubleshooting an issue and cannot cross an obstacle. The ASA is running ASA running 1,0000 code 24. I am using a client VPN tunnel to connect to the ASA. The ASA has already a LAN-to-LAN tunnel, set up and operating and I need the VPN client to access the remote site over the LAN-to-LAN tunnel.

  The internal IP address of the local part is 192.168.0.0/24 and the IP address of the Remote LAN-to-LAN tunnel is 172.20.1.0/24. The clients are distributed 192.168.200.0/24 IPs. I have attached the relevant configuration for the SAA.

  When the VPN client on the network, I can access resources on the ASA network internal. On the internal network of the SAA, users can access resources through the LAN-to-LAN tunnel. Client VPN cannot access resources on the LAN-to-LAN tunnel. For the latter, there are no hits on the C-TEST access list.

  Thank you for your help.

• IKE Dead Peer Detection between Cisco ASA and Cisco PIX

  I have a network environment in Star with about 30 offices of satellite remote using VPN Site to Site connectivity.  The majority of remote satellite offices have the features of Cisco PIX 501 running PIX Version 6.3.  The hub office runs a version 8.2 (1) Cisco ASA.

  I configured Dead Peer Detection on the Cisco ASA device at the office hub with the default settings of the following-

  Confidence interval - 10 seconds

  Retry interval - 2 seconds

  I think I'm right assuming that raises are limited to 3 before the tunnel is completely demolished.  Basically, the problem that I am facing is with several remote satellite offices.  What seems to be the case, the tunnel between the remote offices and the hub is demolished (probably because of the length of IKE, always 86400 seconds) and the tunnel then fails to renegotiate unless traffic is physically forced from the hub office.  The tunnel NOT to renegotiate after satellite office, ONLY the end of the hub; so that means sending traffic to the satellite when the VPN tunnel is out of service, not to renegotiate the tunnel.  The Hub office is a colo and therefore traffic rarely comes to that end, the tunnel remains so down until manual intervention occurs and the ICMP traffic is forced into the tunnel.

  Should the KeepAlive and retry interval settings corresponds to both ends, for example if the two devices be configured for DPD?

  What are the potential pitfalls to the extension of the life of IKE, and this will help or even hinder the problem?

  Thank you in advance for helping out with this.

  Hi Nicolas,.

  I think that the two DPD settings must match on both ends, if these do not match then problems like yours might arise which seems to happen here, is that one end shows a tunnel down, but the other end may not detect it down, we could have to watch debugs, or record two ends to see if this is the case , setting in the meantime ike DPD for same timers could hetlp on.

  In regard to the increase in the life expectancy of IKE, well you just need to be aware that this could allow keys to be discovered since these are not renegotiated unless the tunnel is down on the level of IKE. Other than that I don't see why this would affect you.

• Transfer between Cisco ASA VPN Tunnels

  Hi Experts,

  I have a situation where I need to set up the transfer between two VPN Tunnels completed in the same box ASA. A VPN Tunnel will incoming traffic and that traffic should be sent to the bottom of the other VPN Tunnel to the ASA. The two VPN Tunnels are from the Internet and speak with the same IP address of the ASA peers.

  Retail

  Tunnel A

  Source: 192.168.1.0/25

  Destination: 10.1.1.0/25

  Local counterpart: 170.252.100.20 (ASA in question)

  Remote peer: 144.36.255.254

  Tunnel B

  Source: 192.168.1.0/25

  Destination: 10.1.1.0/25

  Local peer IP: 170.252.100.20 (box of ASA in question)

  Distance from peer IP: 195.75.75.1

  Can this be achieved? what configurations are needed in the ASA apart cryptographic ACL entries?

  Thanks in advance for your time.

  Believed that, in this case your config is good, and you can avoid using routes on your asa since it must route based on its default gateway, make sure you have good sheep in place rules and the inter-to interface same-security-interface allowed return you will need.

• Established but LAN-to-Lan tunnel can not ping to a host on the inside

  We have two cisco vpn concentrator (3005).

  Behind, we use 172.20.167.0/24 (Headquarters)

  Behind, we use 172.20.184.0/24 (remote desktop)

  We are starting to do a lan-to-lan tunnel, the tunnel establishes no problem.

  the only problem is that I can ping only the inside interface of the

  hub of central administration. I can't ping (or other

  communicate to) hosts

  on each subnet.

  On each side, you must make sure that all your hosts know that the road to the other network is by the local hub or using static routes on each host, or adding routing appropriate on any device is your default gateway.
