• 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:

  attributes of hostname (config) #-Group Policy DfltGrpPolicy
  hostname (Group Policy-config) #vpn - idle - timeout no

• Easy VPN between two ASA 9.5 - Split tunnel does not

  Hi guys,.

  We have set up a site to site vpn using easy configuration vpn between ver 9.5 race (1) two ASA. The tunnels are up and ping is reached between sites. I also configured split tunnel for internet traffic under the overall strategy of the ASA easy vpn server. But for some unknown reason all the customer same internet traffic is sent to the primary site. I have configured NAT to relieve on the side of server and client-side. Please advise if no limitation so that the installation program.

  Thank you and best regards,

  I have the same question and open a support case.

  It's a bug in the software 9.5.1. See the bug: CSCuw22886

• IPSec tunnel do not come between two ASA - 5540 s.

  I've included the appropriate configuration of the two ASA lines - 5540 s that I'm trying to set up a tunnel of 2 lan lan between. The first few lines show the messages that are generated when I try to ping another host on each side.

  Did I miss something that will prevent the tunnel to come?

• ASA 5505 - I can't create an IPSEC VPN between two ASA 5505

  Hello

  I have two ASA 5505 with basic license and I'm trying to create a VPN IPSEC using the CLI. Here are the steps I did:

  1 Configure ASA-1 (host name, vlan 1 and vlan 2).

  2. configure a static route

  3. create object network (local and remote)

  4. create the access list

  5. create ikev1 crypto

  6. create tunnel-group

  7 Configure nat

  and I repeat the steps above with the ASA but another change IP.

  Are to correct the above steps?

  Why can I not create an IPSEC VPN between devices?.

  No, you needn't. The ASA configuration is ok. Packet trace proved it. I think it can be a problem on the hosts. Please, check the firewall on the PC and try to put out of service, if it is running.

• site-to-site between two ASA firewall

  Hello

  I have two ASA and I have set up the two ASA til S2S. ASA1 is in HQ and ASA2 is in Office of Brunch. HQ ASA has multi S2S connection and Brunch ASA has only S2S to Headquarters. The Senario is I want to send all traffic (both Internet and LAN in the ASA HQ) ASA2 throug the tunnel. The problem is that when the tunnel is up and there is ASA2 connevtivity (brunch office) for the network local behinde ASA1 (HQ), but the client behinde ASA2 has no conectivity when they try to go to the Internet. Tanks a lot in advance for any help!

  ASA HQ extern ip 192.x.y.z/24, LAN 10.70.0.0/16

  Brunch of the ASA Office a extern ip 168.x.y.z/24, LAN 10.79.1.0/24

  This should help you:

  Global 1 interface (outside)
  NAT (inside) 1 0.0.0.0 0.0.0.0

  access extensive list ip 10.79.1.0 inside_nat0_outbound allow 255.255.255.0 255.255.255.0 x.x.x.x
  access extensive list ip 10.79.1.0 outside_1_cryptomap allow 255.255.255.0 255.255.255.0 x.x.x.x

  x.x.x.x = subnet HQ, in the ASA HQ you need of the opposite ACL:

  permit inside_nat0_outbound to access extended list ip x.x.x.x 255.255.255.0 10.79.1.0 255.255.255.0
  permit outside_1_cryptomap to access extended list ip x.x.x.x 255.255.255.0 10.79.1.0 255.255.255.0

  This way to the internet traffic will be coordinated because it turns off and traffic to the VPN will be
  not be translated as she goes down the tunnel

• 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.

• L2l VPN between two ASA5505 works not

  Let me start who I know a thing or two about networks.  VPN not so much.

  I am trying to configure a Site-toSite VPN between two ASA 5505.  I am building this in a laboratory of the Office before I deploy it to the end sites.  I are the indications on this very informative forum and think I have it set up correctly.  I can see the tunnel is being built and I see same incrementation of the traffic counters.  But the real user sessions do not seem to work.  For example, ping and telnet does not work.

  An excerpt from the syslog for a ping test on a computer on the remote end.

• VPN failover between the ASA

  I do a search in the search of the best solution for switching between two ASA and hoped that someone wants to point me in the right direction.

  The situation is this, we got:

  -Head Office 2:

  Each is equipped with an ASA 5505

  -10 branches

  Each is equipped with a 887 integrated services router.

  Each is BranchOffice must have a redundant VPN connection at the headquarters of these two, and they all need to use the first person as main and the other in high school. In case of failure, all branches need to use the second connection VPN going the second seat.

  In my research, I'm looking for the best possible solution, with faster failover, but have no idea where to start my research.

  I hope someone has a good answer for this one.

  Thank you very much in advance,

  Kind regards

  Dwayne

  I do not understand why people continue to use ASA devices for VPN endpoint.  the ASA is NOT designed for complex VPN scenarios.  It is designed for simple scenarios.  In terms of VPN by using comparison, ASA is a person with a basic education while Cisco IOS is like a person with a college degree.

  For the scenario, you will be much better using Cisco IOS routers everywhere, where you can implement the GRE/IPSec or DMVPN.  Both cases will be sastify to your needs.

• ASA between two buildings W / different subnets. How to extend the network?

  I have two buildings with two different networks. Users to build one want to be on the network to build two. Standard range of course will not work if I should put two ASA both buildings and the [IPSEC] VPN between the buildings, extension of the network? Will this work? If so, where are the commands in the Guide of Config ASA?

  Thank you... If you can get this for me very fast.

  Matt

  Matt, a litle more information would help every building completely separate in terms of connectivity physical any fiber between them, are are the two buildings of the same company? everyone has his own Internet access provider?

  If there is no connectivity between them that the internet and if each building has its own ISP is therefore assumes that there is already a firewall, if that's the case, you can implement vpn L2L and connect the two networks via Ipsec via internet.

  Here's a typical scenario

  Good news, that VPN has been implemented!

  According to the ping problem, my suggestion is to check, if some type of firewall based on host computers on both sides block ICMP requests.

  Anyway, you can still use the capture of packets on the inside of the interfaces of the two ASAs, to check if the ICMP traffic is to reach the ASA.

  In addition, you can try to enable ICMP inspection:

  Policy-map global_policy
  class inspection_default

  inspect the icmp

  inspect the icmp error

• 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 VPN between two routers - mode ESP Transport and Tunnel mode

  Hi experts,

  I have this question about the Transport mode and Tunnel mode for awhile.

  Based on my understanding of 'Transport' mode is not possible because you always original "internal" private in the IP headers or IP addresses. They are always different as public IP on interfaces enabled with Crypto Card addresses. When encapsulated in the VPN tunnel, the internal IP addresses must be included or the remote VPN router won't know where to forward the packet.

  To test, I built a simple GNS3 with three routers laboratory. R1 and R3 are configured as VPN routers and the R2 must simulate Internet.

  My configs are also very basic. The R2 is routing between 1.1.1.0/24 and 2.2.2.0/24. It is defined as the gateway of R1 and R3.

  R1:

  I configured transform-"null" value, while it will not encrypt the traffic.

  Then I tried the two 'transport' mode and mode "tunnel". I ping a host in the internal network of the R1 to another host in the internal network of the R3. I also tried 'telnet'. I also captured packets and carefully compared in both modes.

  Packets encapsulated in exactly the same way!

  It's just SPI + sequence No. + + padding

  I will attach my screenshots here for you guys to analyze it. I would be grateful for any explanation. I confused maybe just when it comes to the NAT...

  I guess my next step is to check if the two modes to make the difference when the GRE is used.

  Thank you

  Hi Difan,

  As you point out the mode of transport is not always applicable (i.e. applicable if IP source and destination is equal to corresnpoding proxy IDs).

  A typical scenario in this mode of transport is used:

  -Encryption between two hosts

  -GRE tunnels

  -L2TP over IPsec

  Even if you set "transport mode" this does not mean that it will be used. IOS routers and I blieve also ASA will perform backup even if the mode of transport is configured but does not apply in tunnel mode.

  I can take a look at your traces to sniff, but all first can you please check if you transport mode on your ipsec security associations? "See the crypto ipsec his" exit you will show the tunnel or transport mode.

  HTH,

  Marcin

• E/s Ethernet between two computers

  I have two computers running labview. I'm trying to generate a signal on one and read it on the other. Connection between two computers is ethernet. The problem is that NEITHER MAX cannot detect a network device. I have ping successfully the signal sent to the computer via the command prompt. Any ideas on why MAX can't detect the signalling computer?

  Try running the examples on the same machine. If you can't find the example works between two instances of the application of different on the same computer, then you certainly won't operate on two different machines. Once it works, try using the IP address instead of the host name of the computer. If still no luck, try disconnecting all other networks on both machines.

• Estimate the time between two computers

  Hello, everyone. I want to develop a program for communication between two ip addresses: IP1: 192.168.1.100 IP2: 192.168.1.101 Suppose IP1 is the server IP2 is the Viewer, then I want to put in place a program to estimate the elapsed time for IP1 contact IP2, but I don't know how to do. Also, I want to display the elapsed time for the connection (which varies due to fluctuations in the internet), performing actions such as continuously 'ping' the receiver from the server. Can someone show me the way to achieve this? Thank you very much. Best regards yukfai88

  Please do not shout

  How about using ping?

  Insert the output in an analysis of string to read the value you need. Sorry my OS is in German so you have to adapt ;-)
