ASA5520 v7.2 - How disable VPN traffic?

Hi to all,
I have an ASA5520 with v7.2. I have read in the command reference that, by default, the security appliance allows VPN traffic to terminate on a security appliance interface. And here is my question:
How can I disable that to filter the VPN traffic with my own access-list?
Regards, Fernando.

Hi Shadi,
Thanks for your answer but it is not correct. If you go to "Usage Guidelines" of "sysopt connection permit-vpn" you can read:
"You can require an interface access list to apply to the local IP addresses by entering the no sysopt connection permit-vpn command. See the the access-list and access-group commands to create an access list and apply it to an interface. IMPORTANT!!! --> The access list applies to the local IP address, and not to the original client IP address used before the VPN packet was decrypted."
So that if I disabled "sysopt connection permit-vpn" I will be able to filter the local IP assigned by the vpn_pool but not the real public IP of the client.
Regards, Fernando.

  • Server 2003 routing and remote access not passing VPN traffic

    I've inherited a network that has two IP scopes that are routed through a Windows 2003 server with Routing and Remote Access.  I can ping both sides (we'll call them HQ and Plant) internally.  My firewall has an IP from the HQ IP scope and when
    I connect via VPN, I can see all the devices on the HQ network including the network card that is in the routing server for that "side".  However, if I'm connected via VPN, I cannot get to any of the IPs on the Plant side, not even the card
    in the routing server.  The buck stops on the server.
    I should mention, that the firewall assigns IP addresses that are on the HQ scope, so all VPN connections will have an address from that side.
    I'm lost on how to get this set up so my VPN traffic coming in from the HQ side can be routed to the Plant devices. 

    Hi,
    To be honest, your statement confused me a bit.
    VPN is used for external client get access to internal resource. When we setup VPN server, we usually have two NICs. We need choose a NIC that will be used when client initiate
    a connection request. I prefer to call it external NIC card. The internal one will work as DHCP relay agent. So this is a single way connection. You cannot dial from internal to external.
    If I misunderstood you, please elaborate what you are trying to do.
    Hope this helps.

  • Packet Capture for VPN traffic

    Hi Team,
    Please help me to set ACL and capture for Remote Access VPN traffic.
    Requirement is to see how much traffic is flowing from that Source IP.
    Source : Remote Access VPN IP(Tunneled) 10.10.10.10
    Destination : any
    This is what I did which is not working
    access-list VPN extended permit tcp host 10.10.10.10 any
    capture CAP_VPN type raw-data access-list VPN interface OUTSIDE

    Hello,
    If you set up the capture with that access list, you are filtering just TCP traffic, therefore you won't be able to see UDP or ICMP traffic too, I would recommend you using the same ACL, though using IP:
    access-list VPN extended permit ip host 10.10.10.10 any 
    Capture CAP_VPN access-list VPN interface outside 
    Then with:
    show capture CAP_VPN
    You will be able to see the packet capture on the ASA, though you can export the capture to a packet sniffer as follow:
      https://<ip address of asa>/capture/<capname>/pcap   capname-->CAP
    For further details of captures you can find it on this link
    Let me know if you could get the information you were trying to reach.
    Please don´t forget to rate and mark as correct the helpful Post!

  • Redirecting VPN traffic to WCCP

    I need to be able to redirect my vpn traffic to the wccp on my network. I have read articles about this but cant really find any configuration examples or solid solutions. I read that forcing the VPN traffic to the inside interface will accomplish this, but how is this done? Are they talking about NATing the VPN traffic to the inside interface then re-NATing back out to the internet?

    Have you clear the VPN tunnel down after you added the new subnet DMZ to the crypto ACL? and I also assume that the remote end has added the same mirror image ACL for their crypto ACL?
    Lastly, I also assume that you have configured the NAT exemption on DMZ interface, and perform "clear xlate" after the config?

  • How to route traffic across subnets when one NIC is a hyper-V virtual switch?

    Having a bit of a problem with a hyper-V environment which does not seem to route network traffic on two different subnets between each other.
    If it were a purely physical server with two NICs and a gateway set traffic would automatically be forwarded between the two different subnets.
    However when one of those NICs is a hyper-V virtual switch this simple routing no-longer seems to work and no traffic gets forwarded between subnets?
    Situation is:
    Hyper-V server with two NICs
    NIC 1 = 192.168.0/24 - main Internal company network.
    NIC 2 (hyper-V virtual switch.) = 192.168.1/24 - connects to ADSL internet router
    Virtualized Domain Controller.
    One or two virtualiszed NICs as necessary
    How then does traffic get routed between these two subnets?  If RRAS has to be configured to do this where is the best place to do it, on the hyper-V host or on the virtualized domain controller?
    Thanks,

    Hi ,
    You can create an internal virtual switch and configure an IP for it (I assume it is 192.168.1.2/24) .
    After you enable RRAS in hyper-v host  there will be two gateways for different subnets  .
    " NIC 2 (hyper-V virtual switch.) = 192.168.1/24 - connects to ADSL internet router "
    The problem is here ,if  these VMs need to access internet .
    So , these VMs can not configure their gateway same as the IP of internal virtual switch , you may set VM's gateway as the ADSL internet router's IP meanwhile add a static route entry for every VM .
    Please refer to the Syntax :
    route add -p 192.168.0.0 mask 255.255.255.0 192.168.1.2
    Hope this helps

  • How many vpn can be used simultaneously in Azure?

    I need to add multiple locations to my azure platform approximately 90 branches , I need to know if I should set up a vpn for each branch , or as I should. thank you very much .
    I am from Colombia , if they can write in Spanish would be better

    Hi,
    It seems that you have asked this question before:
    https://social.msdn.microsoft.com/Forums/azure/en-US/c533ff85-c155-4a19-8156-67901da66ee4/how-many-vpn-can-be-used-simultaneously-in-azure?forum=WAVirtualMachinesVirtualNetwork#c533ff85-c155-4a19-8156-67901da66ee4
    Based on my experience, the maximum limitation for virtual networks and local networks is 100 per subscription and the limitation for local network
    sites is 10 per virtual network in Azure. If you connect each on-premise branch with an Azure virtual network, it would be possible to do that. However, the default limitation for virtual networks and local networks is 10 per subscription, you can request
    an increase limitation by following the article below:
    http://azure.microsoft.com/blog/2014/06/04/azure-limits-quotas-increase-requests/

  • How to manage traffic of livestreams or youtube

    Hi all,
    at the moment we are discussing about how to control or limit traffic used by livestreams. At the moment there are many web pages with livestreams of the olympic winter games and customers facing very high traffic by hd videostreams.
    So we are now thinking about managing this videostreams by implementing some policies on the proxies.
    And we alternatively think about how to restrict traffic of videostreams or youtube video using asa.
    Did not find anything in the knowledgebase. Do you have any hints how to manage this?
    thank you in advance and best regards

    Just go trough Manage application and Modify application and use reindex and full process.
    This normally should fix your issue.

  • Enable DirectAccess, Disable VPN

    Hi all,
    I've just completed the upgrade on my Server 2012 Essentials server to R2 and I'm getting DirectAccess setup.
    As my clients are running Enteprise SKU of the OS, I have no reason for the clients to want a SSTP VPN so I'd like to disable the VPN and leave only DirectAccess.
    In the instructions for enabling DirectAccess, VPN is a pre-requisite so I don't want to just go and Disable VPN from the Remote Access Management console without knowing if that's going to hose DA first. Does anyone know the answer to this?
    Thanks,
    Richard

    You may be able to remove the SSTP ports, without disabling the functionality.

  • How to snoop traffic on PGW 2200 with Wireshark

    How to snoop traffic between PGW 2200 & MGX 8880 with Wireshark?

    I hope to have understood correctly your question.
    1) enable the snoop on PGW using ./snoop_scrip in /opt/snoop/ path
    2) collect the trace of the call and so stop the snoop usinf CTRL C
    3) open wireshark
    4) drag and drop the files generated from the snoop in wireshark
    5) wireshark will ask to merge the file
    P.S. PGW uses RUDP to communicate with the media gateway. Set the wireshark RUDP port (in Edit - Preferences - Protocols menu) according to PGW configuration.
