• L2l VPN tunnel is reset during the generate a new IPSec key

  Hello

  Both the log messages seems to suggest that the remote end is closed/compensation connection.

  Is this a new connection that suffer from this problem or has it started on an existing connection?

  The Cisco documentation associated with the Syslog messages does really not all useful information about these log messages.

  I guess that your problem is that TCP by L2L VPN connections suffer from the complete renegotiations of the L2L VPN.

  I wonder if the following configuration can help even if this situation persists

  Sysopt preserve-vpn-flow of connection

  Here is a link to the order of the ASA reference (8, 4-8, 6 software) with a better explanation of this configuration.

  http://www.Cisco.com/en/us/docs/security/ASA/asa84/command/reference/S8.html#wp1538395

  It is not enabled by default on the SAA.

  Hope this helps

• How to get the time limit requested when ping external interface FW IOS?

  After I install CBAC on an IOS Firewall Router and deny all incoming ICMP request, I ping the external interface of the router and I get "response from the (the external interface IP): the unreachable destination network. I think it's quite risky because my IP from the router's external interface is known. How can I set up such that I can get "Timeout asked" instead?

  Hello

  Try not to implement the "unreachable no ip" of your external interface.

  This command prevents the router ICMP unreachable sending at all.

• How to start the initialization of the l2l VPN?

  Hey there!

  I have two PIX501e and trying to implement a LAN2LAN. I have all the settings in place, but for some reason, this isn't negotioating the connection. Y at - it an enable command to negotiate? I enabled on both external interfaces of crypto

  You need to open the traffic from one end to another in order for the tunnel to be built. The traffic that you generate is defined in the field of encryption. So, if you are tunneling traffic RFC1918 IPs (IE. 192.168.x.x), don't forget to do a ping that IP and not the public (or vice versa).

  The field of encryption defines 'interesting traffic', or traffic that the firewall determines must be passed over the tunnel, and not by the bias of the Internet (or any other interface).

• 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.

• WCCP and ASA L2L VPN Tunnel

  How L2L WCCP vpn tunnel? If there is a Web page on the otherside of the tunnel that I need access on ports 80 and 443, it goes through the process of WCCP. How will I know the traffic through the tunnel for 80 and 443 to ignore the WCCP?

  Hello

  I have not had to deal with WCCP on the SAA configurations as it, but to my knowledge, this could be done in the ACL that is used in configuring WCCP on the SAA.

  I mean a single montage we have has an ACL that simply bypasses the WCCP for some destination addresses.

  The ACL was originally for example

  WCCP ip access list allow a whole

  Then we had to stop it for some destination network and we would add a Deny statement at the top of the ACL

  access-list 1 deny ip WCCP line any 10.10.10.0 255.255.255.0

• Question of access list for Cisco 1710 performing the 3DES VPN tunnel

  I have a question about the use of access lists in the configuration of a router Cisco 1710 that uses access lists to control traffic through the VPN tunnel.

  For example the following lines in a configuration on the remote router. My question is whether or not the traffic that matches the definition of list access-130 (something other than 192.168.100.0/24), cross the VPN tunnel or go directly to the Ethernet0 interface.

  My understanding is that traffic that matches the access list 120 would be encrypted and sent through the IPSec tunnel. If there was "ban" set out in the statements of 120 access-list, the traffic for those would be sent through the IPSec tunnel but not encrypted (if possible). And finally, given that the definition of crypto card reference only "adapt to 120", any traffic that matches 130 access list would be sent Ethernet0 but not associated with the card encryption and thus not sent through the IPSec tunnel. "

  Any input or assistance would be greatly appreciated.

  Hello

  I have an ASA5505 that currently connects a desktop remotely for voip and data.  I added a 2nd site VPN tunnel to a vendor site.  It's this 2nd VPN tunnel that I have problems with.  It seems that the PHASE 1 negotiates well.  However, I'm not a VPN expert!  So, any help would be greatly appreciated.  I have attached the running_config on my box, debug (ipsec & isakmp) information and information about the provider they gave me today.  They use an ASA5510.

• The combination catlogs referencing pictures on several external hard drives?

  Hello:

  Working with a client who had about 250 000 images stored on two 2 TB external hard drives... some pictures on each drive...

  We went just to LR CC2015 and I would like to eliminate the redundancy of the CATALOG.

  To get started, I created two catalogues, one for each hard disk and imported (added that copies of the photos of each disc).

  Now I want to combine catalogs in a renowned referencing all the pictures on it

  several external hard drives.

  I think it is ok to do this but it best to double check with forum initially thought. Thanks in advance for the help.

  Barbara Reiner

  You can use the "Import an another catalog" option under the file menu to import a catalog into another. I suggest that you set "File management" as shown in the attached screenshot. In this way there is no need to move/reconnect files/photos associated with the source file.

  

• 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.

  Hello guys,.

  I have Cisco ASA5520 facing the ISP with private IP address. We don't have a router and how to get the IPSec VPN through the internet?

  The question statement not the interface pointing to ISP isn't IP address private and inside as well.

  Firewall configuration:

  Firewall outside interface Gi0 10.0.1.2 > ISP 10.0.1.1 with security-level 0

  Firewall inside the interface Ethernet0 192.168.1.1 > LAN switch 192.168.1.2 with security-level 100

  I have public IP block 199.9.9.1/28

  How can I use the public IP address to create the IPSec VPN tunnel between two sites across the internet?

  can I assign a public IP address on the Gig1 inside the interface with the security level of 100 and how to apply inside to carry on this interface?

  If I configure > firewall inside of the item in gi1 interface ip address 199.9.9.1/28 with security-level 100. How to make a safe lane VPN through this interface on the internet?

  I'm used to the public IP address allocation to the interface outside of the firewall and private inside the interface IP address.

  Please help with configuration examples and advise.

  Thank you

  Eric

  Unfortunately, you can only complete the VPN connection on the interface the VPN connection source, in your case the external interface.

  3 options:

  (1) connect a router in front of the ASA and assign your public ip address to the ASA outside interface.

  OR /.

  (2) If your ISP can perform static translation of 1 to 1, then you can always finish the VPN on the external interface and ask your provider what is the static ip address assigned to your ASA out of the IP (10.0.1.2) - this will launch the VPN of bidirectionally

  OR /.

  (3) If your ISP performs PAT (dynamic NAT), then you can only start the tunnel VPN on the side of the ASA and the other end of the tunnel must be configured to allow VPN LAN-to-LAN dynamics.
