Area-based-Firewall: card crypto / tunnel interface / area?
Hello
We use a router CISCO1921-SEC. On the side "WAN", we have 1 public IP assigned by DHCP address.
At present, we use the WAN Interface with a crypto-map as endpoint of some IPSec connections. We have created a zone - fire-with area "WAN" and "LAN". In this configuration, all IPSec parameters are on a single Interface - connection to the 'LAN' box can be managed through rulesets. What about the connections between IPSec connections and the area "self."
We would like to finish each IPSec connection in a separate area. Is this a good idea?
How can this be configured?
Each of them on a "inetface tunnel" with binding "tunnel source...". » ?
Please give us a clue... Thank you!!
Message geändert durch NISITNETC
When the tunnels are completed on the router, which is the area free, by default, all traffic is allowed, if you want to restrict access, you must create a free zone and add a pair of WAN area to auto.
Hope this link will help you,

Card crypto on Interface Ethernet
Hi all
I don't have that much experience but with VPN configs, so maybe this question will seem a bit silly. I have a Cisco 831 that I use to connect via VPN to a remote site. Everything works fine.
Then I wanted to add a second tunnel to another location. I did all the configs needed, applied card encryption on ethernet external and everything was fine, I could connect. But then I noticed that the new encryption card has actually replaced the existing one. Of course, the first VPN was no longer works.
Is this a limitation of the 831? Or y at - it another way to configure them so I can use the two (or even more than two) at the same time? Do I need another Cisco router if I want more than a tunnel?
Any help is appreciated.
Thank you
Stefan
This isn't a limitation of the router. But by design,.
only one crypto map set can be assigned to an interface. If multiple crypto map entries have the same name but a different seq - num map, they are considered as part of the same set, and all apply to the interface.
So what you need to do is create crypto-map with the same name for slot 2, but give a different sequence number. Apply this encryption card to the interface and it will work. From the seq - num lowest crypto card is considered to be the highest priority, and will be evaluated first.

Card crypto has incomplete registration message
I'm working on the construction of a configuration on a 5540 running 9.1.2 for VPN L2L. When I reboot the device, I get this message:
. ATTENTION: card crypto has incomplete registrations
Out of config line 10665, 'card crypto L2LVPN interfaces... ". »
I seems that it gives me the error on the line where the encryption card is assigned to the external interface. Unfortunately, this message is really not very useful. I don't have it still in production. Is there a way that I can know where my problem maybe?
Thank you.
Jason
Hello
This indicates generally only a connection VPN L2L Crypto map configuration is missing a crucial parameter to make it complete.
Then run the command
See the crypto run map
Then make sure the following lines exist
address for correspondence card crypto
card crypto defined peer
set transform-set ikev1 crypto card
If one of the 3 things mentioned above is missing then crypto map configuration is considered incomplete and does not have the information necessary for this VPN L2L to function.
At least that is what it seems.
It may be useful

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

Card crypto applied to the Vlan Interface of the 1841 router
Currently, our 1841 router has a T1 connected to the WIC T1, Comcast Cable connected to Fa0/0 and the local network connected to Fa0/1. Tuesday, our 1841 will have an ethernet connection to a new gateway router instead of use the WIC T1. I added a 4-port ethernet module to the router in the anticipation of this change. Since the 4-port module is not layer 3 capable, I created a virtual local area network so that I can address the Vlan with the IP address that has been previously configured on the WIC T1. My goal is to move our IPSec vpn tunnel interface series interface vlan newly created. I was able to add all orders of the interface vlan, but I wanted to make sure that when the time comes to make the transition, the tunnel will be actually get when it is configured on an interface vlan that is then assigned to one of the four ethernet ports in the add-on. Has anyone done this or seen that fact? Potential drawbacks? Thank you very much!
Hello
Crypto-map is compatible with the IVR, so if everything else is in place, it does not work.

: endGood news, that VPN has been implemented!
According to the ping problem, my suggestion is to check, if some type of firewall based on host computers on both sides block ICMP requests.
Anyway, you can still use the capture of packets on the inside of the interfaces of the two ASAs, to check if the ICMP traffic is to reach the ASA.
In addition, you can try to enable ICMP inspection:

How does Card Crypto knows what ISAKMP policy to use?

How does Card Crypto knows what ISAKMP policy to use, or use of the ISAKMP policy at all?
It comes from "ipsec-isakmp?
I mean... I do not see any "set isakmp policy 10" in the Crypto map
This is what he chooses just the top-down approach?
As part of the negotiation of the phase 1 and is a top-down proposal based on the sequence number. You can get the details in tunnel using configuration:
Debug crypto ISAKMP
Cisco IOS has built/strategies default ISAKMP, but the pre 15.x versions were terrible default. New default values are strong, although I still like to configure them myself.

Hello
I came across this problem when there are other entries already exist under the same crypto map, and are already applied to an interface.
I found that by denying first crypto map interface command, change the config and re - apply the interface command then it will work very well.
So...
(1) no xxx_map interface card crypto outside
(2) place the lines of crypto map configuration
(3) interface xxx_map crypto map out
Of course, you will lose the existing tunnels if some already set up but then this happens if you reboot anyway!

Easy VPN with the Tunnel Interface virtual IPSec dynamic
Hi all
I configured easy vpn remote on a cisco 1841 and dynamic server easy vpn with virtual tunnel interface on the server (cisco 7200, 12.4.15T14)
It works with easy vpn remote to the client mode and mode network-extesión, but it doesn't seem to work when I configure mode plus network on the client of the cpe, or when I try to have TWO inside the ez crypto interfaces. On the customer's site, I see two associations of security, but on the server PE site only security SA!
Without virtual dynamic tunnel interface, dynamic map configuration is ok... This is a limitation of the virtual tunnnel dynamic interface?
Federica
If one side is DVTI and the other uses a dynamic map, it does support only 1 SA. If the two end uses DVTI or the two end uses dynamic card then it supports several SAs.
Here is the note of documentation for your reference:
Note: Multiple inside interfaces are supported only when the Cisco Easy VPN server and the Cisco Easy VPN client have the same type of Easy VPN configuration. In other words, both must use a Legacy Easy VPN configuration, or both must use a DVTI configuration.
Here's the URL:
Hope that answers your question.

card crypto access lists / problem if more than one entry?
Access list for IPSec enabled traffic.
I've been recently setting up a VPN between two sites and I came across the following problem:
I wanted to install a VPN that only 2 posts from site A to site B, a class C network
So I created a list of access as follows:
access-list 101 permit IP 192.168.0.1 host 192.168.1.0 0.0.0.255
access-list 101 permit IP 192.168.0.2 host 192.168.1.0 0.0.0.255
When I applied the access list above to map (match address 101) encryption, I quickly realized that only the first host (192.168.0.1) was successfully encrypted beeing while the other could not. I've been geeting on ipsec debugging errors saying that traffic to 192.168.0.2 denyed by the access list.
When I changed the access list above with the following
access-list 101 permit IP 192.168.0.1 0.0.0.255 192.168.1.0 0.0.0.255
two items of work could successfully encrypted through IPSec tunnel.
To look further into it, I realized that only the first entry of the IPsec access list has been really tested for the corresponding traffic!
Is this a normal behavior or a known Bug? No work around for this problem?
Kind regards.
If you have ipsec-manual crypto map in crypto ACL, you can specify that an ACE. Check 12.2 docs:
Access lists for labelled as ipsec-manual crypto map entries are limited to a single permit entry and the following entries are ignored. In other words, the security associations established by this particular entry card crypto are only for a single data stream. To be able to support several manually created security for different types of traffic associations, define multiple crypto access lists and then apply each a separate entrance card crypto ipsec-manual. Each access list should include a statement to define which traffic to protect.

Card Crypto GETVPN on loopback
Hello
We have 6 WAN routers connected through MPLS ISP cloud, we must apply GET VPN between these WAN routers.
We have 2 servers of keys (1800 routers), and WAN routers will act as members of the Group (6 GMs)
The configuration files are attached for work typical configuration GETVPN (crypto map applied to the WAN interface)
In the key server configuration, the crypto isakmp command uses the WAN IP of each router WAN (172.16.x.x) address, and since KS routers are connected to the local network (VSS), they should be able to join 172.16.X.X and therefore the subnet in 172.16.X.X is announced for the local network (check GM-configuration file under eigrp - connected redist)
That's what our customers want to avoid! they don't want 172.16.X.X to make advertising for the local network.
I know it's possible in the configuration GETVPN to configure, the command crypto isakmp for use the loopback address of the routers WAN instead of the WAN IP address, but in this case the card encryption should be applied to address loopback, and for this, all traffic to be encrypted and decrypted to go through the loopback on all routers WAN interfaces.
I was wondering what is the best solution in this case, I have to use the config below on GM
card crypto-address loopback 0
TEST allowed 10 route map
set interface Loopback0
TEST IP policy route map-local
But I don't know if it is correct, or there may be a better idea... so I thought share with you guys to discuss all the best ideas.
Ali,
We do not support cryptographic cards on loopback interfaces.
Use the crypto-local address (in the case of vanilla IPsec) card or customer record interface (even if it is for another use) order under specifcy gdoi what inetrface or VRF you want to record source to / receive to generate a new key on.
You can take a look at DIG:
section 4.2.1.2.3 and other talk.

Using the Tunnel interface on router
Hello world
I see hew Tunnel interface on the router.
Router is running OSPF.
However, there is no cryptographic statements.
tunnel configuration
Tunnel1 interface
10.4.x.x from IP x.x.x.x
time 7
source of tunnel Loopback1
destination 10.4.x.x tunnel
My question is when we use the interface Tunnel without any cryptographic statements?
Thank you
MAhesh
This Tunnel is a plain GRE Tunnel. They are generally used without crypto when:
(1) traffic is not sent through an untrusted network and cryptographic protection is not necessary.
(2) the GRE traffic gets encrypted on a separate device if the end point free WILL is not able to do the necessary cryptographic protection.Sent by Cisco Support technique iPad App

PCI-6025E (DAQ) and cards-1409 (Image Interface) PCI
Hi friends,
I have PCI-6025E (DAQ) and cards-1409 (Image Interface) PCI installed on the Windows XP desktop, that connected to the deducted Mikron camera.
Recently I spend my Labview to 8.6, but the Mikron camera installation software does not work.
How can I solve the problem?
Anyone have the installation software (PCI-6025E (DAQ) and cards-1409 (Image Interface) PCI)?
Any suggestion is appreciated.
Thank you
Jack
