• How to accompany the IDS in ASA 5505 and 5520?

  Dear All;

  We have the following configuration of HW for the ASA 5505 and ASA 5520, we add the functionality of system of detection of Intrusion (IDS) to the two ASA. My question is: what are the modules required to support this function, and what is the deference between IPS and IDS, fact the same Module both the feature?

  Okay, I was not quite correct in my first post.

  These modules - modules only available for corresponding models of ASA.

  They all can act as IPS (inline mode) or IDS ("Promiscuous" mode), depending on how you configure your policies.

  When acting as IPS, ASA redirects all traffic through the module, then all the traffic is inspected and can be dropped inline if a signature is triggered.

  When she acts as an ID, ASA a few exemplary traffic is the module for inspection, but the actual traffic is not affected by the module, as it's not inline in this case.

  In addition, these modules can be both comdination. That is part of the traffic can be inspected "inline", when some other (more sensitive) traffic can be inspected in promiscuous mode.

• VPN site to site & outdoor on ASA 5520 VPN client

  Hi, I'm jonathan rivero.

  I have an ASA 5520 Version 8.0 (2), I configured the site-to-site VPN and works very well, in the other device, I configured the VPN Client for remote users and works very well, but I try to cofigure 2 VPNs on ASA 5520 on the same outside interface and I have the line "outside_map interface card crypto outdoors (for VPN client). , but when I set up the "crypto map VPNL2L outside interface, it replaces the command', and so I can have only a single connection.

• Using Cisco Client to site VPN on a behind a NAT ASA 5520

  I apologize if this has been asked and we answered in the forums.  I looked, and while I found a large number of entries that were dancing all around this question, I never found nothing which addressed this specific issue.   We currently use an ASA 5520 as the head end of a relatively large customer to site IPSEC VPN (approximately 240 users, not consecutively).   This ASA is currently sitting behind a Checkpoint firewall with a real publicly addressable IP address on its public interface.  All of our customers use the legacy Cisco VPN (not the one anyconnect) client.  We plan to a few controllers F5 link set up between ISPS and firewalls.   For VPN connectivity F5 recommends that we NAT IP address (called a broad IP) to point back to a private IP address on the ASA and F5.  My question is, will this work?   I've always heard say that the head of line needed to have a public IP address on this subject because this is what will be placed in packages for the client to respond to.

  For further information, here's what we have now and what we are invited to attend.

  Current

  ISP - router - firewall-fire - ASA (public IP address as endpoint)

  Proposed

  ISP - router - F5 (public IP address as endpoint using a NAT to ASA) - Firewall - ASA (10.X.X.X as its external interface)

  Proposed alternative

  ISP - router - F5 (public IP address as endpoint using a NAT to ASA) - ASA (10.X.X.X as its external interface)

  All thoughts at this moment would be greatly appreciated.   Thank you!

  Hello

  If there is a static NAT one by one on F5 to the external interface of the ASA, then I don't think they would be any problems.
  Because when the client will attempt to connect to IKE to the translated public IP, F5 will redirect the request to ASA outside interface that is configured for the VPN.

  In addition, to ensure the udp500, 4500 and esp is allowed and then you should be good to go.

• Configure the ASa 5505 of remote site by using ASDM

  I would like to be able to administer the ASA 5505 from another site, which is connected via a LAN of Ipsec site-to-site.

  How to activate this feature?

  Hello

  You can remotely administer an ASA using the public IP address (via the Internet), or through the tunnel to the private IP address.

  You can reach the private IP address by activating the command:

  management-access inside

  You can access the ASA by IP address private via CLI or GUI.

• IPSec VPN to asa 5520

  Hello

  First I must admit that I am not very versed in Cisco equipment or in general IPSEC connections so my apologies if I'm doing something really good obviously stupid, but I checked through any kind of things that I could find on the internet on the configuration of IPSEC VPN.

  The setup I have is an asa 5520 (o/s 8.2) firewall which, for now, is connected to a temporary connection beautiful style home broadband for testing purposes. The netopia router is configured to allow ipsec passthrough and redirect 62515 UDP, TCP 10000, 4500 UDP, UDP 500 ports in the asa 5520.

  I'm trying to connein out of a laptop with disabled windows firewall and vpn cisco 5.0.02.0090 client version.

  I ran several attempts through the ipsec configuration wizard options. most of the time that nothing comes in the newspaper to show that a connection was attempted, but there is a way I can set up product options the following on the firewall log:

• Tunnel VPN ASA 5520 (DMZ + INSIDE) destined for OUTSIDE

  I can't find any reference to anywhere else.

  We have an ASA 5520 to our site HQ (inside the network) with several regional subnets on the DMZ interface.

  We need connectivity VPN Site to Site between the INSIDE and a remote control on the OUTSIDE of the site, as well as between the DMZ subnets and even outside the site. The interface from the OUTSIDE of the SAA must be local VPN endpoint for all tunnels.

  I created a S2S VPN between the INSIDE and the OUTSIDE site and it works great.

  When I create a VPN S2S tunnel between a site of DMZ and even outside the site (using the same settings the and remote, but with a cryptomap different because the local subnet (DMZ) is different from the other inside the subnet, the traffic gets the mapping (show crypto isakmp his) to the same cryptomap that was created for the access to the tunnel from the OUTSIDE) , instead of to the new cryptomap, so remote endpoint deletes it, and traffic also causes SPI incorrect of for the remote endpoint, which makes the original INTERIOR outside OF THE VPN tunnel to fall from time to time.

  Is this a bug?

  I also did a local S2S VPN tunnel configuration test of networks as everything INSIDE and the DMZ. With the help of the wizard VPN S2S leads ASA only to create a NAT rule exempted for the subnet on the INSIDE interface. Can I manually create another tax-exempt NAT rule to the side of the DMZ and use this a S2S tunnel to connect sites inside and DMZ to the remote OFF-SITE in a connection profile?

  I'm building a Rube Goldberg?

  Thank you

  George

  Hi George,.

  It seems you have a situation overlapping it, are you sure that subnets inside did not overlap with the networks from the DMZ?  A package tracer could clarify wha that the ASA is actually sending.

  In addition, you can merge the two interfaces on the same card encryption if you wish, just make sure that the NAT is configured correctly.   For example; Source NAT (all, outside) static...

  The VPN is OK? ("' isakmp crypto to show his" should show a MM_Active tunnel to the peer address ")

  Normally exempt us VPN site-to-site of NAT traffic. This could be your problem. If you can share your configuration, we can have a look.

  p.s. you should affect the question of the security / VPN forum.

• SSL VPN using ASA 5520 mode cluster - several problems

  I configured 2 ASA 5520 s in the load balancing cluster mode. I connect using anyconnect and I download the customer the first time and everything works well except outlook. I don't know why outlook does not work.

  The second problem is after the anyconnect client is installed on your machine, he remembers that ASA (say ASA2) he first connected and the GUI shows the address IP of ASA2 instead of the virtual IP address of the cluster. I want users always connect using the virtual IP address.

  The third problem I have is there is a default group of SSL VPN and I want all users to use this group. In the initial web page, there is a drop down menu which shows that this group, but I still want to disable this menu drop-down.

  Any suggestions?

  To disable the drop-down menu, you can turn it off with the command

  WebVPN

  no activation of tunnel-group-list

  This will take care of your last issue.

  ***************************

  You can create a profile of the Anyconnect client with the name of the server you want to connect with and that make the ASA that will solve your problem of virtual IP.

  **************************

  Regarding Outlook, do you use specific ports which allows inspection of the ASA. Take a look at the list of inspection on the SAA and perhaps try to disable inspection and see if it works.

• ASA 5520 and MPF

  Hi all. In our company we have recently upgraded our PIX 515 firewall to ASA 5520, and we started to live a thing strange event. On one of the sites we host, I saw a lot of outdated SSM messages popping up and I think that they are the source of the problem when they surf the site (mainly surfing works fine, but sometimes people cannot content etc.).

  I found the Cisco solution for this problem by using the MPF, but one thing confuses me. If I ask a MPF allowing adults MSS on the external interface of the ASA does this political conflict with the comprehensive policy that is on the SAA by default or can they both at the same time?

  Thanks in advance for any help.

  You can have a single policy per interface and another - global, that by default applies to default-inspection-traffic.

  See http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/mpc.html for more details.

• 1841. ASA 5520 VPN

  I set up a VPN site-to site between a Cisco ISR 1841 and a Cisco ASA 5520, everything seems to work but I have a few questions.

  1. I must explicitly authorize all VPN traffic in the ACL on the external interface of the 1841, y at - it an equivalent of router "vpn sysopt connection permit?

  2. Although the VPN rises and pass traffic, I have the opportunity to see what follows?

  * 14:11:52.883 22 June: % CRYPTO-6-IKMP_MODE_FAILURE: fast processing mode has failed with the peer 1.1.1.1

  You can share the outputs full? Both sides at the same time?

  Bottom line, I don't think it's normal in IOS 12.4 mainline unless packages are leaking clear ;/

• Routing with Cisco ASA 5520 VPN

  I have installed IPsec vpn remote users in the Cisco ASA 5520 using RADIUS in my main network. Works very well. I have a site to my Cisco ASA5520 tunnels going to other sites, some of the tunnels have Cisco ASA and some have SonicWalls. I wish that my users VPN remote IPSec to be able to navigate in these tunnels is a site to access remote subnets attached to these tunnels. Do I need to use a combination of routing and the ACL? Or can I just use ACL only? Or just use routing only?

  Thank you

  Hello

  The key to set up here is the two ACL of VPN L2L end points that determine the 'interesting' traffic to connect VPN L2L. You will also need to confirm that the connection of the VPN Client is configured so that traffic to the remote sites have sent to the connection of the VPN client. There are also other things that you should check on your ASA plant

  Here most of the things you usually have to confirm

  • Set up 'permit same-security-traffic intra-interface' if it is already present in your configuration
    • This setting will allow connections to form between the hosts that are connected to the same interface on the ASA. In this case, applies because the VPN client users are connected to the interface 'outside' of the ASA and also remote sites are connected to the ASA to "external". If the traffic between the remote VPN Client and VPN L2L sites will be to enter and exit the same interface
  • You will need to check how the customer if configured VPN connection. Split or full Tunnel tunnel
    • If the connection of the VPN Client is configured as Split Tunnel then you need to add all the networks from the remote to the Split Tunnel, so that the connections between the VPN Client is transmitted to the ASA and from there connections VPN L2L
    • If the connection of the VPN Client is configured as full Tunnel, then there no problem that all traffic is transferred to the Client VPN connection all its assets
  • Define the VPN pool in the ACL of VPN L2L
    • You should make sure that the pool network VPN Client is defined in the ACL that define 'interesting' traffic to connect VPN L2L. So, you need to add the pool VPN VPN L2L configurations on the sites of Central America and remote control
  • Configure NAT0 / NAT exempt for remote VPN Client to L2L VPN Site traffic at both ends of the VPN L2L
    • You must ensure that the NAT0 / exempt NAT rules exist for the VPN Client for Remote Site traffic. This will have to be configured on the SAA "outside" interface. Format of configuration varies naturally a bit on the ASA Central his software level.

  These should be the most common things to set up and confirm for traffic to flow between the VPN Client and Remote Sites

  Hope this helps please rate if yes or ask more if necessary.

• ASA, VPN Site-to-Site

  Hello

  I would like to VPN site-to-site using ASA 5520 and I have some question if you don't mind:

  Site A:

  Peer IP address: aaa.aaa.aaa.aaa/32

  Local network: bbb.bbb.bbb.bbb/32

  Site b:

  Peer IP address: xxx.xxx.xxx.xxx/32

  Local network: yyy.yyy.yyy.yyy/32

  on the site to site vpn Wizard (site B), the network of peers should be site A and the LAN must be site B and remote network must be the site one right?

  the IP address of the local network should be not be used right by other devices on the right? I can use use a unique IP address instead of the beach of network on the LAN and remotely? from the client on site give me a unique IP address?

  can I allow on site A browse only a single IP address on my site B and allowing only ports 80 and 443, please can you give me example I prefer ASDM.

  Thank you and waiting for your help.

  Hello

  I can only really give an example of this using the CLI (or I rather do as I do not use ASDM almost at all)

  You have all already existing L2L / Site to Site VPN connections on the SAA?

  Could you share your current configuration (delete all sensitive information) so we can take into account all existing configurations you have

  Did you agree on what will be the settings phase 1 VPN L2L and Phase2 with the other sites technical contact who will set up their side of the L2L VPN?
