Which interface does "crypto map vpn" get assigned to?

I'm setting up a site to site vpn and have been reading some examples, but my 871 uses a vlan so it confuses me a bit. Do I assign the statement crypto map vpn to the vlan1 interface or fe4 which is my WAN side.

Sander
If we knew more about your environment we might be able to give better answers. In general the crypto map is assigned to the outbound layer 3 interface. But I can not tell from your description whether fe4 or VLAN 1 is the outbound layer 3 interface. Does fe4 have an IP configured on it? If so then perhaps it is the outbound layer 3 interface and gets the crypto map. Or perhaps VLAN 1 is the outbound layer 3 interface and gets the crypto map.
If this helps you figure it out that is good. Otherwise perhaps you can provide some clarification of the environment.

Crypto map VPN 270 set peer 12.2.3.4 12.5.6.7

All
A previously setup tunnel has (2) ip addresses defined in the crypto map. I was advised that one of the ip is no longer valid.
Can i remove one of the ip's without losing the other?
no crypto map VPN 270 set peer 12.2.3.4

Yes you can.
thanks

Which client does the Integration imports get imported into?

In all of the documentation it just says to import the appropriate imports, but into which client should they be imported, 000 or in our case 800 (IDES version of BW/BI 7) which is the client we will be connecting to BOE?
Thanks!
Ryan S.

Bashir-
Thanks for the reply. My question is regarding the transports that need to be imported into your R/3, BW, ERP system so that it can connect with BOE. The transports that are in the /Transports directory when the integration kit is unzipped. I haven't seen any documentation on which client on my BW system these transports should be imported into. Should it be 000 as they are cross-client type of things or do the transports need to be imported to the client you will be connecting to BOE?

"Crypto map" to inside/internal interface. Possible?

Hi, I have a two routers on a point to point VPN where the "Crypto Map" statement is assigned to the external interface as normal. This works fine but I need each router to present a different IP address to that of the external interface.
For example:
crypto isakmp policy 1
encr 3des
authentication pre-share
lifetime 3600
crypto isakmp key privatekey address 4.4.4.4 no-xauth
crypto ipsec transform-set 3des esp-3des esp-sha-hmac
crypto map VPN 1 ipsec-isakmp
set peer 4.4.4.4
set transform-set 3des
match address vpn
interface FastEthernet0/0
ip address 4.4.4.4 255.255.255.252
ip nat outside
ip virtual-reassembly
speed 10
full-duplex
no cdp enable
crypto map VPN
interface FastEthernet0/1
ip address 8.8.8.8 255.255.255.248
ip nat inside
ip virtual-reassembly
duplex auto
speed auto
Instead of the "4.4.4.4" being presented to the other side of the VPN, I need the 8.8.8.8 to be presented. I've tried just changing the Crypto statements as below but it still presents the 4.4.4.4 probably due to the interface the Crypto map is applied
crypto isakmp policy 1
encr 3des
authentication pre-share
lifetime 3600
crypto isakmp key privatekey address 8.8.8.8 no-xauth
crypto ipsec transform-set 3des esp-3des esp-sha-hmac
crypto map VPN 1 ipsec-isakmp
set peer 8.8.8.8
set transform-set 3des
match address vpn
How can I make sure that 8.8.8.8 is what's presented at the other end?
Thanks
Andy

Hi Andy,
I would suggest the following command:
crypto map local-address
http://tools.cisco.com/squish/9c85B
To specify and name an identifying interface to be used by the crypto map for IPSec traffic, use the crypto map local-address command in global configuration mode. To remove this command from the configuration, use the no form of this command.
crypto map map-name local-address interface-id
no crypto map map-name local-address
Example:
interface loopback0
ip address 4.2.2.2 255.255.255.252
crypto map mymap local-address loopback0
interface S0
crypto map mymap
Of course you need to make sure the remote end can reach this additional IP address.
Let me know if you have any questions.
Please rate any post that you find useful.

Converting crypto map to unnumbered VTI

I'm trying to convert a crypto map VPN to a ip unnumbered VTI. The crypto map has been working for months. The VTI... no so much. Here are the applicable config entries.
### original config
crypto isakmp policy 30
encr 3des
authentication pre-share
group 2
crypto isakmp key xxxxxxxx address 10.1.1.10
crypto ipsec transform-set 3DES-SHA esp-3des esp-sha-hmac
crypto map CRYPTO 50 ipsec-isakmp
set peer 10.1.1.10
set transform-set 3DES-SHA
set pfs group2
match address VPN1
ip access-list extended VPN1
permit ip host 172.16.16.10 host 10.5.5.1
permit ip host 172.16.16.10 host 10.5.5.4
I only removed the crypto map and added the following.
### New Config
crypto ipsec profile V1
set security-association lifetime seconds 28800
set transform-set 3DES-SHA
set pfs group2
interface Tunnel0
ip unnumbered FastEthernet0/0
ip nat outside
ip virtual-reassembly
tunnel source 172.16.8.1
tunnel destination 10.1.1.10
tunnel mode ipsec ipv4
tunnel protection ipsec profile V1
I keep getting this ISAKMP error now.
ISAKMP:(0:54:HW:2):deleting SA reason "Recevied fatal informational" state (I) QM_IDLE (peer 10.1.1.10)
Any help would be greatly appreciated. Also... I have no idea what is running on the other end (it's a partner network), but I suspect it's a crypto map on IOS.
Thank you!

Access-lists, FW (ZBF, CBAC) and all other features work on SVTI same way they would work on a physical or other logical interfaces (with very few exceptions).

One crypto map, different tunnel source addresses (secondary)

Hi,
I have two devices with two different (public) IP addresses (Cisco 2811 and Cisco 851), which both host some IPSec tunnels (IPSec/ESP/Tunnel mode). I want to move the 851's configuration to the 2811, and remove the 851 from the network. There is a crypto map assigned to the main outside interface of the 2811 with a few entries. The problem is that I cannot change any of the tunnel TEPs, so the IP address of the 851 must be moved onto the 2811 (as a secondary address). Is there anything I can do to use the secondary address as an IPSec tunnel source? Or do I have to do it using NAT and loopback interfaces?

Source IP addresses for IKE for exchanges leaving out of the same physical interface, ie:
crypto map to-peer_a 10 ipsec-isakmp
set peer 10.1.3.1
set local-address loopback1 <-- new command
match address 100
crypto map to-peer_a 20 ipsec-isakmp
set peer 10.1.3.2
set local-address loopback2 <-- new command
match address 101
Current code allows to specify a local-address for each crypto map only, and not on a per crypto map instance, as suggested above.

Crypto map question

Hi
You can only have one crypto map per interface but you can have separate entries within the same crypto map eg.
crypto map CCS 20 ipsec-isakmp
crypto map CCS 20 match address CCS
crypto map CCS 20 set peer 20.20.20.1
crypto map CCS 20 set transform-set my_ccs
crypto map CCS 30 ipsec-isakmp
crypto map CCS 30 match address PLC
crypto map CCS 30 set peer 10.10.10.1
crypto map CCS 30 set transform-set my_PLC
crypto map CCS interface outside

Multiple Crypto Maps on Single Outside Interface

Hi, I had the following crypto map configured on my ASA5505 to allow Cisco IPSec VPN clients to connect from the outside:
crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 set pfs group1
crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 set 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 ESP-3DES-MD5 ESP-DES-SHA ESP-DES-MD5
crypto map outside_map 65535 ipsec-isakmp dynamic SYSTEM_DEFAULT_CRYPTO_MAP
crypto map outside_map interface outside
I'm trying now to set up an additional crypto map - a static configuration to establish a tunnel with Windows Azure services. The configuration they gave me is:
crypto map azure-crypto-map 10 match address azure-vpn-acl
crypto map azure-crypto-map 10 set peer XXX.XXX.XXX.XXX (obfuscated)
crypto map azure-crypto-map 10 set transform-set azure-ipsec-proposal-set
crypto map azure-crypto-map interface outside
However, when I apply that configuration, my Cisco IPSec clients can no longer connect. I believe my problem is that last line:
crypto map azure-crypto-map interface outside
which blows away my original line:
crypto map outside_map interface outside
It seems I'm stuck with picking just one of the maps to apply to the outside interface. Is there a way to apply both of these maps to the outside interface to allow both IPSec tunnels to be created? We're running ASA version 8.4(7)3.

Hi,
You can use the same "crypto map"
Just add
crypto map outside_map 10 match address azure-vpn-acl
crypto map outside_map 10 set peer XXX.XXX.XXX.XXX (obfuscated)
crypto map outside_map 10 set transform-set azure-ipsec-proposal-set
Your dynamic VPN Clients will continue to work just fine as their "crypto map" statements are with the lowest priority/order in the "crypto map" configurations (65535) and the L2L VPN is higher (10)
And what I mean with the above is that when a L2L VPN connections is formed from the remote end it will naturally match the L2L VPN configurations you have with "crypto map" configurations using the number "10". Then when a VPN Client connects it will naturally not match the number "10" specific configurations and will move to the next entry and will match it (65535)
If you would happen to configure a new L2L VPN connection then you could give it the number "11" for example and everything would still be fine.
Hope this helps

Site to Site VPN working without Crypto Map (ASA 8.2(1))

Hi All,
Found a strange situation on our ASA5540 firewall :
We have couple Site to Site VPNs and also enable cleint VPN on the ASA, all are working fine. But found a Site to Site VPN is up and running without crypto map configuration. Is it possible ?
I tried to clear isa sa and clear ipsec sa then the VPN came up again. Also tested it's pingable to remote site thru the VPN.
I did see there is tunnel-group config for the VPN but didn't see any crypto map and ACL.
How does Firewall know which traffic need be encrypted to this VPN tunnel without crypto map?
Is it the bug ?
Thanks in advance,

It might be an easy vpn setup.
Could you post a running config output remove any sensitive info. This could help us answer your question more exactly.

Can I enter crypto map command on an ethernet interface(LAN)

Hi Friends,
I am establishing VPN tunnel through Internet. I have the public address configured on Ethernet interface of router connecting the LAN. Can I bind the crypto map command to this inside interface and establish the VPN connectivity from this interface. Please help me providing the knowledge.

your crypto map must be bound to outside interface.
but you can chose which ip to use

Hollow stars.... itunes assigns an album average based on my star ratings, but in what scenario do Songs get assigned a hollow star? does itunes acquire info from other media programs or solely from what ive rated in itunes, or does itunes use other peoples ratings... Hollow Star assignment basis?

If you assign songs a rating an unrated album gets an automatic rating, which you can override by rating it.
If you assign an album a rating unrated songs get an automatic rating, which you can override by rating them.
iTunes doesn't import ratings from tags, or third party services. You set them.

Rejecting IPSec tunnel: no matching crypto map entry for remote proxy on interface outside.

Hi,
I have read a problem where the VPN between an ISP and ourselves started dropping sessions. I have rebuilt the crypto map and tried to dig deeper into my config and some basic troubleshooting while I await the ISP to respond.
Any ideas?

Are you trying to send traffic destined towards the internet from 172.16.0.0/20 via this ASA as well? why? are you inspecting those traffic before being sent out to the internet?
If so, this end also needs to be configured with "any" as well --> crypto ACL needs to mirror image.
access-list outside_1_cryptomap extended permit ip any 172.16.0.0 255.255.240.0
Then you also need NAT on the outside interface, otherwise, traffic from 172.16.0.0/20 is not PATed to a public IP, and won't be able to reach the internet:
nat (outside) 1 172.16.0.0 255.255.240.0

Crypto Map on Loopback interface or Physical Interface

Dear All,
When we try to apply the crypto map on any physical interface or the loopback interface on WS-6506-E, it is showing the error. But the same i could apply on VLAN interface. Can anyone explain me what is the issue..?
6506(config)#interface loopback 3
6506(config-if)#crypto map XXXX
ERROR: Crypto Map configuration is not supported on the given interface
Any hardware limitation?

This was proven to break CEF in the past and is a bad design choice by default.
Newer release do not allow you to configure this.
If you're curious if it will work for you check releases prior to 15.x.
