• Dynamic crypto several cards on the interface

  I have an ASA 5540 executes code 8.2. The firewall has tunnels, VPNS, IPSec standard on this remote access VPN and SSL VPN without client.

  I have 1921 Cisco routers with 4 G wireless cards must open dynamic VPN with the ASA 5540, so it seems that I need to implement a solution of EzVPN here.

  My question is, multiple dynamic crypto maps are supported on a single interface?

  For example, the current configuration of lists

  PFS set 20 crypto dynamic-map outside_dyn_map Group 1

  Crypto-map dynamic outside_dyn_map 20 the value transform-set ESP-3DES-SHA

  map outside_map 65535-isakmp ipsec crypto dynamic outside_dyn_map

  outside_map interface card crypto outside

  In addition to cryptographic cards for static L2L tunnels.

  I guess when I add the EzVPN I have to create a new dynamic map. After having done that, simply add something like that?

  card crypto outside_map 65534 ipsec isakmp dynamic outside_new_map

  Basically a different sequence number and card name?

  Hi Colin,

  It is fundamentally correct, that you will encounter some problems on incoming connections, two on the external interface dynamic crypto map entries.

  One possibility would be to include a return address for correspondence for you EZ - VPN, for example, generously describe the Remote LAN as the destination of the encryption access list.

  For example if your remote LAN is all within the range 10.66.0.0/16 set up an access as list:

  outside_new [local area network] ip access list allow [local mask] 10.66.0.0 255.255.0.0

  and include it in you card crypto dynamic outside_new_map

  PFS set 20 crypto dynamic-map outside_new_map Group 1

  Crypto-map dynamic outside_new_map 20 the value transform-set ESP-3DES-SHA

  crypto dynamic-map outside_new_map 20 the value corresponds to the address outside_new

• 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. »

• 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 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

  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

• Losing the ability to telnet after crypto card

  Hello

  I have 2 Configuration of DSL routers with a VPN tunnel between them. The VPN works great. Before you configure the tunnel, I got telnet/SSH access. However, when I apply the encryption card to the Dialer interface, I lose the ability to telnet/SSH to the router. If I remove the VPN configuration, I find the ability to telnet/SSH.

  Any thoughts? I was wondering if the fact of the Dialer interface is a logical interface which causes problems?

  Thank you.

  Tony

  The first thing that stands out is:

  interface Vlan1

  IP access-group 100 to

  interface Dialer0

  IP access-group 100 to

  You don't have a 100 ACL in your config file. I would define an ACL for the inside interface based on security policy and apply the inspection on this interface to set the way back (temporary dynamic holes in the firewall).

  Similarly, configure an ACL for the external interface enabling connections SSH ISAKMP and ESP launched on this side, with inspection to configure the way back.

  I think you should be more specific with your NAT ACL:

  access-list 120 deny ip 192.168.1.0 0.0.0.255 192.168.5.0 0.0.0.255

  access-list 120 allow ip 192.168.1.0 0.0.0.255 any

• Cisco 877 - issue crypto card

  We have implemented a L2L VPN between a cisco 877 and an ASA 5505.

  On the side of 877, we have:

  Dialer 0: connect to the internet and has a dynamic IP given by ISP

  Loopback1: has a static IP address of the public IP range assigned.

  VLAN 1: has a static private IP address for the local network

  FE3: Interface conencted to lan

  We have the following problem.

  We have applied the card encryption to the loopback interface and with this configuration we can reach the interface of the internal router (VLAN 1 IP) from the internal network of ASA, but except that we cannot reach any host inside the router's lan.

  If we apply the encryption card to the interface of FE3 we can ping also lan internal but we lose half of the ping and the return is high (500-800 ms applies rather than 70 to 80 when only 1 Loopback)

  So I need some help here. What should be the correct configuration to have it all works well?

  Thanks in advance

  In the first configuration (crypto-map applied to the loopback interface), you can try this:

• Crypto can be applied by entering ethernet interface.

  Hello

  We try to form a VPN tunnel between two routers connected by point-to-point link between two hosts on part and on the other. (host A to router LAN A to host b. router lan B). We have tunnel successfully implemented by the application cryptographic cards for two series of routers interfaces. Data from host a to host B by this tunnel formed on the serial interfaces.

  This is, what serial link toggle ISDN backup takes and data are transferred via ISDN link, as crypto is not applied to the ISDN data past unencrypted. To work around this situation, is possible to apply the crypto to fastethernet interfaces of routers, in this case the data that can go by series or ISDN, it will be permanently encrypted.

  The configuration is very simple.

  We establish the tunnnel as address serial peer, can we put peer as ethernet addrsss addrees and form the tunnel.

  We tried, but it doesn't work.

  Any link on cisco.com is much appreciated.

  Thankx in advance

  Subodh

  Hi Subodh

  You must apply the encryption on the BRI interface card too so that also your crossing of data through the IRB gets encrypted.

  I feel in this case, you must create another card encryption with similar parameters so that you can apply the same on BRI interface.

• VTI and crypto card

  Hello

  I wonder if it is possible to have a configuration in IPSEC tunnel, in which one side of the tunnel is configured with static VTI and the traditional second with crypto-map.

  If so, how the configuration on the crypto-Map site should be configured.

  Thank you in advance for an answer.

  Concerning

  Lukas

  Lukasz,

  This config is impractical for several reasons.

  VTI dictates that a "any any" proxy set ID is negotiated. While this works well on a virtual interface, where routing can push traffic to a specific interface, it will make ALL traffic is encrypted on crypto maps side and expect all traffic is encrypted when it is recived (because crypto card is part of ECAS in the Lane exit).

  A more practical approach in the world of Cisco is multi SA DVTI, where a DVTI can put end to any kind of insider tunnel (i.e. allow us DVTI to manage several SAs under a virtual interface) it works very well in some cases.

  You can have DVTI on your end and allow the clients to use almost anything (from ASIT cryptographic maps).
  I'll shoot you as an email at the same time, a bit stuck on something at the moment.

• VPN Site-to-Site - cannot ping the router's internal IP address

  Hi guys,.

  I configured a VPN site-to site between two routers, everything works well except ping the internal (LAN) IP of a router.

  Everything works fine: ping the hosts through the tunnel in both feel.

  Routers that I use:

  -IOS 1841: M3 15.0 (1)

  -2811 IOS: 15.0 (1) M5-> here is the problem. I can't ping the inside interface of the router.

  I checked its ipsec counters and it seems that it does not send packets through the tunnel when I ping from the LAN interface.

  #pkts program is not incrementing.

  Anyone had this problem before?

  Thank you very much.

  Best regards

  I think that happens because when the router responds to icmp request he gets is outside interface IP (not the IP Address of the inside interface, wich you are trying to ping) as the source of a package. If icmp-response does not go in the tunnel, because the IP address in the router's external interface is not included in the crypto-acl.

  Solution to this, if it's correct guess, is to add the router's external IP to the crypto-acl.
