• Multiple Crypto cards on a single Interface of ASA

  Hello

  I work with a TAC support engineer, and while troubleshooting it suggests to assign two different cryptographic cards on a single interface.

  It is technically possible to have multiple Crypto maps on a single Interface ASA?

  PS: I know have several sequences in a single encryption card would work, but it is a case that I must address multiple Crypto maps on a single ASA.

  Hi Ali,

  The rule is by interface, a single card encryption is supported. You cannot assign more than one encryption on a single interface card.

  Documentation: -.
  "You can only assign a single encryption card defined on an interface. If multiple crypto map entries with the same name of card but a sequence number different, they are part of the same series and are applied to the interface. ASA first assesses the entry card crypto with sequence number low. »

• Redundant interfaces with Management0/0 on ASA5510

  Readers,

  Is it possible to configure redundant interfaces on the management port?

  Thank you

  Timothy

  Is Timothy. I think that's what I said to technically not possible to bring together, on the same firewall. If you need redundancy, you must have a firewall failover.

  Alternatively, if you wish, you can monitor the firewall on other available ports.

  Does that answer your question?

  Happy new year. have a great year ahead.

• Interface Source ASA IPSEC

  Hello...

  Is there a way to configure an IPSEC VPN with a source interface as in a router? This is a site to site VPN. I want to use a loopback interface.

  When I set up a VPN, the only option is the IP address of the interface where the traffic is going out.

  Thank you.

  Which interface you enable ipsec on is the source interface.

  MyMap [interface name] crypto map interface

  ASA does not support the telesignalisations it is not possible.

• Installation of firepower on redundant ASA 5512 x pair

  Hi, I am trying to install the firepower on pair redundant asa5512x that is configured in active / standby. These asas have an IPS module installed. I need to remove the old IPS module and install the module of firepower.

  I know I need to stop existing ips module, uninstall it, then load the image to start fire etc... However, I have no experience working with redundant units so I don't know how to install firepower in a configuration of active / standby.

  I tried instructions guides on how to do this upgrade of ips in a redundant pair of asa, but the only guides I've found so far speak upgrade firepower in unit asa autonomous.

  any suggestions, instructions or links to blog/sites that provide instructions step by step on the upgrade of firepower in active/standby mode would be much appreciated.

  Thanks in advance.

  I understand say you that uninstalling ips module cause failover? This should be ok because ASA 9.2.x and earlier the pair HA monitors the State of default service module and which cannot be disabled.

  9.3 ASA presented

  (no) monitor-interface service-module

  .. what allows to disable this behavior. Even on 9.2.x, however, you should be able to uninstall on the rescue unit. When you say that it didn't work, this error message do you have? Is about, I would say: 1. Uninstall secondary ips - standby. Primary-active should see module go down and score watch is not ready. 2. repeat on active primary. When the primary unit active reload, the secondary-sleep should see no assets to mate and the active role. You should now have this situation of active secondary and primary-secondary 3. Install sfr on primary-secondary. Load the boot image, perform the initial configuration module and load running image. 4. install sfr on secondary assets, including the loading and installation stages. When primary-secondary sees reloading secondary-active, it must assume the active State and be primary active. After charging high school-watch it requires correspondence module type (IE both have installed SFR). 5. Save and check the connection to the management center of FireSIGHT on two modules of sfr. 6. create and deploy strategies to the modules in the two ASAs. 7 change the service policy to redirect traffic to the module of sfr for inspection by the policies deployed on these modules, ASA.

• ASA 5505 VPN easy & 3rd / DMZ interface

  We have many new and very small remote sites that need to connect via an ASA5505 via easy VPN.  Works without a problem and we have the configuration and the process nailed.

  The challenge that I received today involve non standard remote sites, where I need to set up a third interface an ASA 5505 and allow it to go directly to the Internet and do not go through the VPN.  Configuration of the third interface, assignment and configuration of the ACLS / NAT (PAT) are towards the front.

  The challenge I face and have not been able to find a direct response to is if it is possible to have the easy process of extension of VPN traffic avoidance.  Currently, traffic is down the tunnel which is not what I want.

  I'm afraid I'll have to build conventional site-to-site VPN configurations which is not a huge problem, if it breaks all the methods of maintenance/operations, process, and I have to spend time training of the support team how to detect the differences.  Either yes I can build if someone else needs the support, which means different is a problem.

  Thank you

  What version of the software you run ASA?

  I found this in the configuration guide that suggests that only the highest security level interface is encrypted by the easy VPN tunnel, if you run ASA version 7.2.3 and above:

  http://www.Cisco.com/en/us/docs/security/ASA/asa82/configuration/guide/ezvpn505.html#wp1025408

  So, if your DMZ does not have the same level of security as your inside interface, DMZ traffic does not pass through the tunnel.

  Also, do you have split tunnel configured on the easy VPN server for this easy VPN clients group?

• Cisco ASA failover KeepAlive - classification and prioritization

  Hello

  I have a busy layer two link between data centers and must ensure that traffic keepalive failover between ASA firewalls at each data center goes through.

  I want to implement layer 2 quality of service on the route. Can you classify and prioritize ASA failover keep alive the traffic? If so what ports should I use or it is already ranked by the ASA?

  Thank you

  Hello

  If you want to apply the QoS on switching between ASA link, you need to do:

  -Mark traffic on switches facing interface failover ASA

  -All intermediate switches must approve the value of QoS and applye your QoS policy (reservation of bandwidth based on qos value chosen before).

  Assume that your main unit failover ip is 192.168.100.1 and 192.168.100.2 for the secondary unit.

  The acl to classify the traffic is:

  Of with the ASA2 ASA1

  HA - ASA extended IP access list

  permit ip host 192.168.100.1 192.168.100.2

  Of ASA2 to ASA1:

  HA - ASA extended IP access list

  ip licensing 192.168.100.2 host 192.168.100.1

  Hope that answers your question.

  Thank you.

  PS: If this solved your problem, please do not forget to note and mark it as correct.

  Mahesh,

  The physical SSM management interface is distinct from ASA base. Since can connect you independently, you can assign an IP address in a subnet is appropriate in your environment. Make sure that the physical connection goes to a switch interface in the VLAN correct associated with this subnet. Usually, we use the same subnet as the management interface of ASA, but is not mandatory.

• ASA 5510 replacement and ARP

  Hello support,

  Probably a simple question and can be buried in these forums (but I'm not).

  I am trying to replace one 5510 with another 5510 and have all kinds of difficulties.  Devices the PAT against the external interface have no problem out, but anything with a 1:1 NAT cannot.  Cries of an ARP issue; However, to restart the switch and firewall are without effect.  Is there something else I could potentially be missing.  Configurations are completely reversed.  And the firewall, that the I'm replacing has no problem going out with NAT (static) 1-to-1.  Any ideas?

  Hello

  I assume you mean a L3 switch that you begin with the ASA?

  If this isn't the case, then where is the gateway of your ASA L3 and who manages this device?

  One thing that comes to mind associated with ARP is that if you use several public subnets on your ASA. For example 30 for network connection between your site and the ISP and some 28 as a public subnet for purposes of NAT static. Then you may experience problems IF your software has changed to 8.4 (3) or something higher.

  If ARP is the problem then it is of course the option that makes you check the original interfaces of ASAs (connected to the ISP) MAC address and configure this same MAC address to the new WAN ASAs interface to the ISP.

  You can actually go under the interface and deliver MAC address with the command

  0000.1111.2222 Mac address

  In addition, naturally when it comes to configurations and firewall rules you can always use the command "packet - trace" to simulate the packets from your local network for the EXTENDED or WAN network to the local network and see the race passes through completely.

• ASA - added a public server and it is limited to this traffic

  I added an internal e-mail server to a whole new ASA5510 today.  I used the GUI because it is a fairly simple installation.  In any case, I added a mail server to allow the port 25 inbound on an address static nat dedicated to this server.  But now, this server can not do anything on the internet: the navigation or search DNS, etc..  The server is also the internal DNS server.  I'm probably missing?

  Hello

  It not on MAC address about proxy arp

  • Addresses on the same network as the interface is mapped.

  If you are using addresses on the same network that the mapped interface, the ASA uses proxy ARP to respond to all ARP requests for mapped addresses, thus intercepting traffic destined to a mapped address. This solution simplifies the delivery because the ASA is not to be the gateway for all additional networks. This solution is ideal if the external network contains a sufficient number of free addresses, a consideration if you are using a 1:1 translation as dynamic NAT or static dynamic NAT PAT greatly expands the number of translations, which you can use with a small number of addresses, so even if the addresses available on the external network is small, this method can be used. For PAT, you can even use the IP address of the mapped interface.

  

  Note If you configure the mapped interface to be any interface and you specify an address that is mapped to the same network as one interfaces mapped, then address topographiee in an ARP request for who arrives on a different interface, then you must manually configure an ARP entry for this network on the interface of penetration, by specifying its MAC address (see the arp command). Normally, if you specify an interface for the mapped interface, then you are using a single network for addresses mapped, so that this situation would not occur.

  • Addresses on a single network.

  If you need more addresses available on the mapped interface network, you can identify the address on a different subnet. The upstream router needs a static route for mapped addresses that points to the ASA. Otherwise for routed mode, you can configure a static route on the SAA for mapped addresses and then redistribute the route using your routing protocol. For transparent, if the real host is directly connected, configure the static route on the router upstream to point to the ASA: specify the IP address of the bridge group. For remote hosts in transparent mode, in the static route on the router upstream, you can also specify the IP address of router downstream.

• ASA - AIP - SSM design review

  Hello

  If anyone can offer you please, you will enjoy

  We have 2 ASA 5520 with SSM modules in. behind ASA is a CSS load balancer. This load balancer have ssl and ssl certificate installed module. communication from the internet to the VIP loadbalancer is SSL, the SSM module configured to control communication is limited because everythng is encrypted.

  communication between the LB farm and the server is not encryted, but there is no IPS inbetween. can you suggest if someone used the design below

  int 1 (public) - ASA1 - LB 1 interface (dmz) - inside (inside) ASA1 interface where all the web server resides

  Therefore, the traffic is on port 443 to the virtual IP address. Static on ASA 1forwards traffic to its dmz interface where 1 LB, then clear the 1 LB traffic goes to the inside interface where all the serverfarm web resides. by doing so, we can configure the SSM module to monitor the traffic of LB to webserverfarm since its between 2 interfaces of ASA. and also we can have access - list on ASA to allow traffic only between LB and Web servers

  This will be a concern on the performance of the ASA?

  What is a recommended design

  Thank you

  It is a valid design and it should work.

  The ASA will see traffic twice and the interface that is in front of the LB will see traffic entering the lb twice so I'm not sure that it is effective. Please check the amount of traffic will see interfaces to see if the ASAs can manage it.

  Since the LB will be the one actually pulling pages and to talk to your servers, why did you not pass by the ASA, but external users from do not by it, when speaking of LB?

  If you are worried about BACK against LB and you do not have another firewall to use so I assume that it is valid.

  I hope it helps.

  DMZ servers can goto Internet via the external interface

  The DMZ servers cannot Ping inside the network

  I've been using IpSec VPN on my router,

  clients connect to the router using the Cisco VPN Client software,

  NOW, when I understood ASA in the network, VPN clients are unable to communicate with the servers in the DMZ

  ICMP pings are not stateful. The firewall needs special treatment to dynamically allow pings back, this is done through the "ICMP inspection." The ICMP inspection is disabled by default. You can activate the inspection or use an ACL to allow ICMP traffic. Here is a useful link:
