The ASA can use 2 dynamic cryptographic cards on the external interface?

We have an ASA which is currently used with dynamic VPN. I don't know the pre-shared key.  If I was going to try to create another card encryption. I did not want to bring another drop.  I know that the router does not allow.  It would replace the existing info.  I wasn't sure of the SAA.

David,

The pre shared key is defined in the specific tunnel-group, not in the crypto map.

tunnel-group ipsec-attributes

pre-shared key cisco

However, by default:

Dynamics of LAN-to-LAN tunnels using the 'DefaultL2LGroup '.

L2TP/IPsec connections use the 'DefaultRAGroup '.

In order to see the pre shared key in clear text: "more system: run".

You can have a single card dynamic encryption card crypto, but you can have multiple entries / map instances of this dynamic, for example:

Crypto-map dynamic dynamic_map 10 the value transform-set ESP-AES-256-SHA

Crypto-map dynamic dynamic_map 20 the value transform-set ESP-AES-192-SHA


map outside_map 65535-isakmp ipsec crypto dynamic dynamic_map

More info:

Let me know if you have any other questions.

  • Access ASDM ASA on the external Interface

    We have three ASA5510s, each configured for ssh and http access to the Cel outside.  One of them has aaa users/passwords defined for both ssh and http.  I can access the ASA configured for aaa of the designated host allowed in the external interface normally using credentials of the aaa.  When I try to access one of the other two, they will refuse the enable login password.  The configured aaa ASA is version 8.2 with ASDM 6.21.  The other two are the two ASA version 7.0 with ASDM 5.07.  The ASA requires aaa is configured for https access?  How can I make these other two accept the ASDM login?  Thank you!

    If you do not have aaa then configured for ASSISTANT Deputy Ministers, you must use empty username and password enable.

    Also, you can use the "aaa authenticate http LOCAL console" and use a user/pwd to a private 15 user name to connect to the ASDM.

    To resolve what is a failure you can activate "debug http" and "debug aaa" on the SAA to see the reasons for which the user is rejected.

  • VPN client and ssh to the external interface of the ASA

    Hello world

    I was testing clientless ssl in my lab at home.

    When you're connected via vpn without customer, I am able to ssh ASA outside interface, but when I use ssl vpn only I can't ssh to the external interface of the ASA.

    Need to figure out how I can ssh to the external interface of the ASA using clientless ssl vpn?

    Concerning

    MAhesh

    Mahesh,

    When you are on clientless SSL VPN to your customer is not limited routes of the Internet, isn't being NATted etc. If ASA is set to allow ssh from outside, then the VPN SSL without client user is no different from any other.

    A the user SSL VPN full tunnel can have any or all of these factors at play. One of them can cause the impossibility to access the ASA outside interface via ssh. I see the configuration to tell you which one (or more) is to blame.

  • Multiple Crypto cards on simple external Interface

    Hi, I got the following encryption card configured on my ASA5505 to allow Cisco IPSec VPN clients to connect from the outside:

    crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 pfs Group1 set

    Crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 value transform-set ESP-AES-128-SHA ESP-AES-128-MD5 ESP-AES-192-SHA ESP-AES-192-MD5 ESP-AES-256-SHA ESP-AES-256-MD5 ESP-3DES-SHA MD5-ESP-3DES ESP-DES-SHA ESP-DES-MD5

    outside_map card crypto 65535-isakmp dynamic ipsec SYSTEM_DEFAULT_CRYPTO_MAP

    outside_map interface card crypto outside

    I'm now trying to set up a map of additional encryption - a static configuration to establish a tunnel with Windows Azure services. The configuration, they gave me is:

    Crypto map Azur-crypto-map 10 correspondence address azure-vpn-acl

    crypto azure-crypto-card card game 10 peers XXX.XXX.XXX.XXX (hidden)

    card crypto azure-crypto-map 10 set transform-set of Azur-ipsec-proposal-set

    Azur-crypto-card interface card crypto outside

    However, when I apply this configuration, my Cisco IPSec clients can connect is no longer. I think that my problem is that last line:

    Azur-crypto-card interface card crypto outside

    that blows away my original line:

    outside_map interface card crypto outside

    It seems that I'm stuck with just picking one of the maps to apply to the external interface. Is there a way to apply both of these cards to the external interface to allow the two IPSec tunnels to create? We lack ASA version 8.4 (7) 3.

    Hello

    You can use the same "crypto map"

    Just add

    card crypto outside_map 10 correspondence address azure-vpn-acl

    crypto outside_map 10 card game peers XXX.XXX.XXX.XXX (hidden)

    card crypto outside_map 10 set transform-set of Azur-ipsec-proposal-set

    Your dynamic VPN Clients will continue to work very well that their statements "crypto map" are in the order of precedence / low in "crypto map" configurations (65535) and VPN L2L is higher (10)

    And I want to say with the above is that, where a connection VPN L2L is formed from the remote end it will be naturally VPN L2L configurations you have with the number of configurations "crypto map" '10'. Then when a VPN Client connects it naturally will not match the specific configurations of the number "10" and will move to the next entry and the match (65535)

    If you happen to set up a new connection VPN L2L then you might give him the number "11" for example and it would still be fine.

    Hope this helps

  • Network for access to the external interface inside

    Hey,.

    I have an ASA5520 7.2 (1) I have a few probs with - which is something I struggle with that.

    I'm trying to hit a website of a host on the inside network that is actually hosted internally, but decides the static NAT would focus on the external interface of the firewall.

    Now I can see the TCP built, translation occurring at a port on the external interface, this port high dialogue to one of the static electricity would be addresses on the external interface, then that's all. There are no more entries in my journal in regards to the connection and I get not syn on the internal web server is so the connection is not back in.

    Can't say I've seen this before, but SSH is easy to do on the SAA.

    I recommend you to take out the first interface access list to see if that would be it.

    You have published only a partial section of the config, but make sure you have the SSH command with the address of the subnet that you connect from. Your config is no longer visible as I type this but try "SSH 0.0.0.0 0.0.0.0 outdoors. This allows all subnets access to the external interface. This command works as an access list to restrict connectivity to approved subnets. i.e. ' SSH 10.0.0.0 255.0.0.0 out "only allow hosts on the 10.x.x.x network to connect via SSH.

    Turn 'debug ssh' to see what errors are too.

    And, you can always remove your keys (related encryption rsa key) and rebuild their return (encryption key generate rsa 1024 mod gen). This will make your ssh client, I use PuTTY, think that this is a new feature and invites the OK to connect.

    Good luck.

  • VPN SSL from the inside on the external interface

    Hi all

    First of all I know that I can activate the SSL interface inside, but that's not what I need or want.

    Scenario:

    Several interfaces and VLAN on the SAA (running 8.0.5).

    SSL VPN configured and enabled on the external interface.

    Need to know if it is possible to access the SSL VPN from other interfaces directly to the IP address external interface, something like her hairpin.

    Possible a solution (if it exists) with or without NAT (I have public IPs on some interfaces).

    This will be useful for users who can connect any interface (inside, outside, or other) and with only a DNS record, I'll be able to manage everything.

    Concerning

    PS: Is DNS doctoring an option? The tests that I have done this does not work.

  • Static and VPN on the external interface

    Hello

    Can someone tell me if it is possible (and if so, how) do vpn enabled on the external interface and to have something like:

    public static x.x.x.x interface (indoor, outdoor)

    IE: I have two addresses ip - one for the router an e0 on the pix. I create a static and lists of access to allow inbound http/https server inside but I also want to allow vpn hit e0 and work. My configs work if I use an ip address 3 for the static, but not if they share. I can imagine that the static method takes the vpn traffic before the pix can use it OR maybe as the pix has no route to the now (due to the static method) that it cannot answer?

    Hope I'm making sense

    Thanks for the time spent on this

    see you soon

    Andy

    I think you want something like this:

    public static tcp (indoor, outdoor) interface http 10.10.10.10 http netmask 255.255.255.255 0 0 (where 10.10.10.10 is your web server)

    public static tcp (indoor, outdoor) interface https 10.10.10.10 https netmask 255.255.255.255 0 0

    access-list 101 permit tcp any host x.x.x.x eq 80 (where x.x.x.x is your IP interface)

    access-list 101 permit tcp any host x.x.x.x eq 443

    Access-group 101 in external interface

    It will be useful.

  • Change the IP address of the external Interface

    I need to change the IP address of the external interface remotely.  I have SSH in to the ASA plan and make a change.  I can't be there to make this change, since the site is out of State.  There will be problems?  The current configuration is

    interface Ethernet0/0
    nameif outside
    security-level 0
    IP 66.102.7.22 255.255.255.248

    The new IP address will be 66.102.7.18 255.255.255.248.  Also, is this the right syntax?

    interface Ethernet 0/0

    no address ip 66.102.7.22 255.255.255.248

    IP 66.102.7.18 255.255.255.248

    Thank you.

    Diane

    Diane,

    If you access the ASA via its public IP address on the external interface, and if you change this IP address, you will lose communication with the ASA.

    It's better if you can make the change from the inside.

    If you need to change remotely, you can change the IP address, and then try the SSH connection to the new IP address.

    However if a problem occurs, you cannot access the ASA.

    The syntax is correct.

  • Telnet on PIX with the external interface

    Is there a way to telnet in PIX Firewall through the external interface?

    SSH is a valid method to access the site, but I wonder if there is another way to do it. PDM is another tool for access and modification of the configuration.

    Any help will be useful.

    Best wishes

    Onur

    I'm pretty sure that Telent directly to the external interface of a PIX is not available. It is such a big security risk that it is not offered as an option.

    SSH is a much better way to go (even if it's only SSH1).

    You can probably VPN in your network and Telnet from inside.

  • VPN; list of access on the external interface allowing encrypted traffic

    Hi, I have a question about the access list on the external interface of a router 836. We have several routers on our clients site, some are lan2lan, some are client2router vpn.
