Crypto maps
Here our provider links all our sites via point to point crypto maps on a wes circuit, will all these point to point maps be on there own /30 masks, how are these set up with regards to addressing etc ?
Hi Carl,
As far as crypto maps are concerned, the peer address configured in the crypto map should be reachable. It doesn't matter that it needs.
Mostly the peers are located far away from each other, with ip connectivity between them.

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

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.

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. -

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.

Crypto map mymap command I am not familiar with
I have the following commands in a new pix I am taking over and I am not sure what they do?
crypto map mymap client configuration address initiate
crypto map mymap client configuration address respond
any help would be appreciatedHi .. they are used for remote VPNs:
1.- crypto map mymap client configuration address initiate
explanation: Use the crypto map mymap for remote vpn clients and the PIX Firewall will attempt to set IP addresses for each client.
2.- crypto map mymap client configuration address respond
explanation: Use the crypto map mymap for remote vpn clients and the PIX Firewall will accept requests for IP addresses from any
requesting client.
I hope it helps .. please rate if it does !! -
Crypto map on PIX versus router
Hi all,
i am looking for eqvivalent of IOS command:
crypto map xxx local-address Loopback0
Is it possible to link crypto map with other IP address as real interface address on PIX?
Thank you in advance.Hi Rick,
now we have two gateways in our company. One is used for VPN traffic, x.x.x.254 and second is used for normal traffic.
Now we want to unified these gateways to one PIX ... and i am looking for simplest way.
For us, the simplest way is to use crypto map on PIX with IP address x.x.x.254 but with ip address of physical interface x.x.x.y.
Now i know, that it is not possible to do it on PIX ... so i am looking for another solutions.
Problem is, that we have our bussines partners, that know our actual IP ... and have firewalls opened for that IP :)
I think that best solution will be NATing traffic to these customers to old IP.
Thanks for your info. -
Hi all, when doing an access list for encrypting traffic on a crypto map, what kind of access list do you use, and do you permit destination traffic to be encrypted or source ?
Carl,
Extended ACLs are used to define interesting traffic which needs to be encrypted.
access-list 101
hope this helps ... -
Crypto Map on Tunnel interface

Cisco 5520: removed crypto map still in effect
so i typoed a command: "crypto map Map1 7"... instead of "crypto map Map1 70".
I cleared the Map1 7 entries, and added the correct entries in Map1 70.
I cleared all of the vpn sessions:
no crypto map Map1 int outside
cl ips sa
cl isa sa
Now, however, whenever I try to ping the remote network from the inside interface, it seems to read the Map1 7 policy instead of Map1-70.
Is there anyway to clear the Map1 7 entries from memory? I'm trying to avoid rebooting the firewall.
Thanks,
Jeff
But when I tryWith ASA you need the "clear configure" command to remove a crypto map sequence number
clear configure crypto map map-name seq-num

WARNING: This crypto map is incomplete
Hi ,
i have ASA with 4 l2l vpn configured. as now am trying to configure new VPN tunnel; while configuring of crypto map set match add its giving me
error like ... WARNING: This crypto map is incomplete
as i have read all the discussion from forms its not effecting ; request you to please help
Thanks
GajendraHi,
This is a normal message and just tells you that you have not yet entered all the "crypto map" commands related to this new connection to make the configuration complete
You will essentially have to make sure that you have ATLEAST the following lines configured
crypto map match address
crypto map set peer
crypto map set ikev1 transform-set
The "transform-set" part might NOT need the "ikev1" depending on your ASAs software level.

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

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

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).
