Application of VPN S2S packet capture

Dear team,

Consider the below configuration of IPSec site to site vpn between two firewalls, I would like to capture packets in each direction 1 firewall.

LAN - wan - ip - wan - ip - Lan 2.2.2.2 1.1.1.1 172.16.1.1 - 10.1.1.1

lan2pc 172.16.1.100 = ASA2 = {ISP} = ASA1 = lan1pc 10.1.1.100

Can I use the screenshots below to see if the packets are transmitting properly? Or would I need to use any other filter to capture packets?

Assuming that I started a traffic interesting as 10.1.1.100 ping machine 172.16.1.100 and assuming I'm facing some decaps or program values increment no questions, for which I want to make these troubleshooting. Pls help.

Hi s HE,

If you are looking for a way to solve traffic problems that capture works perfectly well.

Hope this info helps!

  • Packet capture vpn access list filter

    I just install a VPN filter to secure traffic between two of our facilities. As a good security admin, I am only allowing good ports and blocks everything else. Now I see one-way packet loss.

    I wanted to set up a capture of packets to detect which packages were being allowed and which were dropped. However, none of my packet captures are showing all the captured packets. I tried the following shots.

    capture the data interface type DPEP bullies xo [Capturing - 0 bytes]
    match ip 10.1.8.0 255.255.252.0 all

    capture the data type DPEP raw access-list 105 interface xo [Capturing - 0 bytes]

    capture the data interface type DPEP raw asa_dataplane [Capturing - 0 bytes]
    match ip 10.1.8.0 255.255.252.0 all

    It is certainly a problem of formatting on my part that I am does not detect traffic to subnets that the traffic that goes with success.

    Any help would be appreciated. Thank you.

    Hi Michael,

    do not change the VPN filter... you created a dummy access just to capture list and who as a rule and use it to capture.

  • How to pass the traffic of a site VPN S2S by ASA to another S2S VPN site?

    I have a need for hosts on separate VPN networks connected to my ASA corp to communicate among themselves.  Example: Host A site 1 a need to communicate with host B on the site 2.  Both sites 1 & 2 are connected via the VPN S2S.  I would get every site traffic to flow through the ASA at the other site.  Where should I start my configuration?  NAT? ACL?

    I can ping each host in the network Corp. but cannot ping from one site to the other.  I set up same-security-traffic permit intra-interface and addition of NAT and rules the ACL to allow/permit 1 Site to contact Site 2.  When I do a trace of package through Deputy Ministers DEPUTIES, packets are allowed to pass. I read different that tell no NAT y at - it something at the other end of the VPN to do?  should NAT and ACLs rules be mirrored? Just in case, a site is an instance of MS Azure VM and the other is a 3rd party VM instance.

    On the HubASA, can I set up a new card encryption that selects the Site1 Site2 traffic and protect the traffic and value her counterpart Site2 public IP or just add this selection of traffic to the existing encryption card for the existing tunnel between HubASA and Site2?

    Just add this traffic to the existing encryption card.

    Remember that this should be added on three routers (two hubs and there has been talk).

    Site1

    CRYPTO ip access list allow Site2 subnet >

    CRYPTO ip access list allow subnet training3 >

    CRYPTO ip access list allow subnet HUB >

    Site2

    CRYPTO ip access list allow Site1 subnet >

    CRYPTO ip access list allow subnet training3 >

    CRYPTO ip access list allow subnet HUB >

    Training3

    CRYPTO ip access list allow Site1 subnet >

    CRYPTO ip access list allow Site2 subnet >

    CRYPTO ip access list allow subnet HUB >

    HUB

    CRYPTO_1 ip access list allow Site1 subnet >

    CRYPTO_1 ip access list allow Site1 subnet >

    CRYPTO_3 ip access list allow subnet training3 >

    CRYPTO_3 ip access list allow subnet training3 >

    CRYPTO_3 ip access list allow subnet training3 >

    Each of these ACLs is attributed to their respective crypto cards.  CRYPTO_1 is assigned the site1 crypto map, CRYPTO_2 is assigned to the site2 crypto card... etc.

    I hope that's clear

    In addition to this, you need to configure identity NAT / NAT provides both the HUB and the spokes of sites.

  • Packet Capture on ids

    Hello

    We need the 'packet capture' setting on all the signatures of attacks on a joint-2 V4.1.4 and a sensor 4210 V4.1.4. We use CiscoWorks VMS for the configuration of all sensors, but there seems to be no way to enable this setting for a selection of signatures at a time. This is apparently a different setting than the ip logging (for which we can select a large number of signatures to be configured at the same time). It seems to me that the only way to change this is to go into each separate signature configuration and change the value there. But it is almost not doable. Any other possibility?

    Now that IPS Version 5.0 was officially announced (to be released early next month), I can tell you about some of the new features that can help in this area.

    The new IDM (Intrusion detection device manager) which is that tool for basic configuration for the web of the sensor will allow you to select several signatures (now the control key while you select each signature), do a right click to bring up a window of action event and grant shares of event (such as the Packet Capture, which was renamed ProduceVersboseAlert in 5.0) for all signatures in a few mouse clicks.

    So you will not need to manually edit the XML of the probe to make the same change to a large number of signatures.

    NOTE: I work in the team of sensor and therefore did not expertise on product ID MC (VMS). I don't know if this same functionality offers the IDS MC in virtual machines. But ID MC should, at a minimum, be able to import changes made through IDM.

    Some other new features are what we call risk score and event Action overrides. With the risk rating will now have a level of risk calculated from 1 to 100. The risk rating is calculated according to the severity of the Signature, the loyalty of the Signature (how well it detects that the attack) and the target value (how the target address is important to you).

    Mainly the level of risk is a method to better sort the order of importance of the alarms, but can also be used with the new feature of event Action more than wrinkles.

    Each type of action (such as ProduceVerboseAlert) can be assigned a specific range of risk (for example 80-100) rating. Any alert that has risk rating will have this action also made previously specific action by signature. (If no alert with a risk rating of 80-100 would have ProduceVerboseAlert added to this alert action, if she had not already been configured on the individual signature).

    The filters have also changed a bit.

    You can now name each filter on the sensor itself.

    And even to add a description to a new field of user comments.

    The filters now also filter specific actions (in 4.x all actions has been filtered, but in 5.x, you can filter the actions in the block for example or even allow the alarm to be generated).

  • Multiple context mode, how do I download packet capture file

    Hi guys,.

    Is there a way to download the capture of packets from a specific context? I know I used to use https:///Admin/capture/ to download if it's just a context.

    The ASA uses mgmt 0/0 for the management and it is connected to a separate network of OOB. Only this network has TFTP servers to download the capture file. The context in question is in transparent mode. Its IP address doesn't have access to a TFTP server.

    Thank you!

  • Access to the DMZ to remote sites via VPN S2S

    We have an ASA 5520 and two remote site ASA 5505 that connect to each other through tunnels VPN S2S. They are doing tunneling split, while local traffic passes over the tunnel. We are local LAN (10.0.0.0/16) and our network to the DMZ (10.3.0.0/24) on the main site. The DMZ hosts our external sharepoint, but we access it internally

    The problem is site A (10.1.0.0/24) and B (10.2.0.0/24) have no idea of it, and when you try to go to the site, it fails. You can access it via the external site address, but that's the only way. Normally the external address is blocked when you're an intern.

    That I'm stuck on is even when we had all sent traffic from Site A to our Senior Center, would find it yet. I do a separate vpn purely tunnel that traffic to DMZ?

    Yes. So if you do this in ASDM under Edit Site profile connection Site, it will look like this.

    Local network: 10.0.0/16, 10.3.0.0/24

    Distance: 10.1.0.0/24

  • Ontario Regulation distributes dynamic routes via VPN S2S

    Hi halijenn / experts

    (1) please let me know if IPP works on a Site in tunnel

    (2) I have a behind remote ASA 10.10.1.0 and 10.10.2.0 network that must be distributed to another branch ASA with S2S ASA remote via OSPF

    3) there is an L3 Switch behind the ASA of the branch and Switch L3 there is a router that has a default route pointing router WAN

    Router WAN
    |
    |
    Users-> router-> L3 Switch-> ASA-> Internet-> remote ASA branch (10.10.1.0, 2.0)

    Note: 10.10.1.0 2.0 AND are already configured in the ACL Crypto at the ends.

    Users are able to reach the 10.10.2.X network to the remote end.

    Now for the 10.10.2.0 static routes are already there in the router and the switch finally pointing the ASA branch however as the network grows, it is impossible in the router behind the switch to add static whenever routes (such as the default route to router WAN points). This is why in order to learn routes dynamically, I will add an ospf process to the ASA to branch with the following configuration. Please let me know if iam correct when I add IPP and other OSPF commands to the ASA of the branch. (hope I have nothing to do on ASA remote associated with IPP or OSPF?)

    I take just an example of a remote host 1 10.10.1.4. Inside ASA interface leading to users is 172.16.1.0/24

    access-list redistribute allowed standard host 10.10.1.4 255.255.255.255

    router ospf 1
    network 172.16.1.0 255.255.255.0 area 0
    Journal-adj-changes
    redistribute static subnets redistribute route map

    In addition, I will also be allowing the order for IPP in the encryption of the VPN S2S said card.

    Please help me understand if I'm wrong

    Pls set the OSPF firstly on the SAA process before removing the static routes. Once you have confirmed that the OSPF is configured correctly and the roads are in the OSPF database, then you can delete the static routes. Static routes will always take precedence over OSPF because it has higher metric. Please keep the default route configured on the SAA.

    Hope that confirms it.

  • Integrated Packet Capture: CEF or process switched?

    I have a question about EPC.

    When I configure it there is an option

    LABRTR #monitor capture point ip?
    CEF IPv4 CEF
    switching to packet switching process

    LABRTR #monitor capture point ip

    When I choose different router cef gives me an option to choose the interface, but when I choose to process switching , it gives me a few options.

    I wonder what is the best choice when you are capturing?

    Thank you!

    Hello

    For normal map data packages, use the path of the CEF. For packets that are destined for the router itself, use the dial-up process.

  • The vMA traffic packet capture

    I'm deploying a new VM vMA. I have the virtual machine on a different subnet than my regular production network. Everything is good so far except when I try to run the command 'vma-update' When I do that, I get a message "no route to host". I followed it down to the access list that I have on my switch. Do I have to do now is execute a capture of packets to see what IPS the vMA is in talks with so I can enable them through on my access list.

    What is the best way to run a capture of the vMA packages?

    Well the URL can be solved in several addresses/etc, but I guess already know you that.
