Static VTI tunnel to asa

Hi All,
I need to connect some routers to an ASA using IPSec tunnels. The goal is to get netflow traffic from the routers to a collector behide an ASA using IPSec tunnels.
Recently I found out (locally orginated) netflow isn't properly encrypted when send through an IPSec tunnel (http://www.plixer.com/blog/network-traffic-analysis/sending-netflow-over-ipsec-tunnels/. The workaround seems to be using flexible netflow (which my collector doesn't support) or using a real tunnel interface on the router.
This implies I need to use:
- IPSec/GRE
- EzVPN with DVTI
- SVTI...?
Since GRE is not supported on the ASA and I want the tunnel to be always active, implementing static VTI tunnels might be a good idea. So I would like to use something like this on the router.
interface Tunnel0
ip unnumberd loopback0
tunnel source x.x.x.x
tunnel destination y.y.y.y
tunnel mode ipsec ipv4
My question is, does anybody know if you can build an IPSec tunnel between an ASA and a router, using a SVTI interface on the router? A code sample for the ASA and the router would be more than welcome.
Regards

Hi Hielke ,
if you managed to match the SAs proposed by the router when using SVTI which is any to any , and you will do this on the ASA using a crypto map access-list as follow :
access-list crypto VPN permit ip any any
then all traffic leaving the interface where the crypto map is applied will be subject to encryption , which is not practical in most cases .you may use different interface (on the ASA) to this tunnel with the SVTI as it will use any any and that traffic is different than the one leaving the outside interface .
so as Marcin this will not scale for you

Is it possible to create a VTI tunnel from my 877 router to my ASA

Hi all
I woulke like to know is it possible to create a VTI tunnel from my 877 router to my ASA, rather than creating a cryptomap on the router ?
cheers
Carl

Yes you can
Forgot to add that it possible when configuring ezvpn where the 877 is a remote client and Asa server

Multiple IPSEC tunnels on ASA 5505

Configuring Multiple IPSEC tunnels on ASA 5505
Hi,
I need to configure 2 diffrent type of IPSEC tunnels on my ASA 5505. 1st one is static ipsec tunnel already configured between HO to site A and 2nd one is dynamic to be configure between HO to site B since site B does not have static IP so I have to configure dynamic ipsec vpn.
I have following clarification
1. After configuring dynamic ipsec Is my existing static ipsec tunnel will work simultenously?
2. can I apply different crypmap on the same outside interface? if not then what setting i need to do to make this work?
3. Do i need to create 1 more Nat0 or can i add in existing ACL which i have already created for previous.
kindly help me on this
Thanks in advance

SRX Using DHCP on UNTRUST (BRANCH)-- Connected to Static VTI Cisco Router (HQ)

Good morning Gentlemen, I need some advice. I am primarily a cisco IOS chap, but have recently been delving into some JUNOS action.
I cannot find an example on the Juniper Forums/Documentation or the Cisco Forums/Documentation to my specific Issue.
Firstly, I am not interested in Policy Based VPNs. I do not know if it is possible to use a DHCP assigned public address on remote device with a "static VTI" - when using IKE identities. However as Phase one is up, I think the issue is more to do with Phase2 proposals when not explicitly defining a Tunnel destination.
In the scenario I am trying to sort now, I have an SRX-100 device, that gets its public address from a DHCP server.
I have back at the HQ, a cisco router.
The Cisco router has various VTI tunnels out to other branch devices, that are smaller Cisco routers. These VTI tunnels are working fine - note all using static Public IP's
I have my phase1 up fine, (from both sides' perspective) and am sending a local-identity hostname instead of a defining a destination address on the Tunnel on the cisco side.

remote ident (addr/mask/prot/port): (0.0.0.0/0.0.0.0/0/0)
I have tried sending this as the proxy-id on the Juniper to no avail.
The error is still :
*Jun 6 10:20:07.244: ISAKMP1110):atts are acceptable.

*Jun 6 10:20:07.244: ISAKMP1110): phase 2 SA policy not acceptable!

So it is something to do with the SA/Proxy ID's being sent.

FYI - If I use the Provider given DHCP address on the Cisco Tunnel config, as a destination - the tunnel comes up immediately....So ' thinking this may be a limitation of static VTI. I have not tested the IKE identity on a remote cisco router also using VTI yet.
e.g.
interface Tunnel1
description HQ to NC-SRX
ip address 10.1.1.1 255.255.255.252
tunnel source 4.4.4.4
tunnel mode ipsec ipv4
tunnel destination 1.1.1.1
tunnel protection ipsec profile NICK-SRX-IPSEC-PROFILE
So I guess my question is Is this possible using a static VTI?
What does this comand do - does it turn on dynamic VTI (all that virtual-template business)- or just tell the tunnel to expect and IKE identity?
tunnel destination dynamic
Does Dynamic VTI work with Different Vendors, and if so how can you control what VRF is assigned to the tunnels - I will need in the future multiple VRF's for each branch device, some using DHCP public addresses.
The VTI design guide does not mention Identity IKE for branch sites without using dynamic VTI.
I would like to avoid using the whole easyVPN / dynamic VTI, as I need to use multiple VRF;s on the endpoints.

Perhaps this fellow has cracked it - is this the only way ???

Using Crypto Maps and IPsec Static VTI's on the same router

Is it possible to configure both crypto maps and IPsec static VTI's on the same router? What platforms have this capability? What IOS version do I need?

Yes you can and as far as I know I dont think there is a hardware dependency.
VTI mode 'tunnel mode ipsec ipv4' was added in 12.3(14)T.
If you are mixing tunnel protection and crypto map ensure you use iskmp profiles to differentiate somehow that the tunnel IPSec connection is not prcessed on the crypto map!
Here is a rough example (fine tune it as needed):
crypto keyring key1
pre-shared-key address 1.1.1.1 key test123
crypto keyring key2
pre-shared-key address 7.7.7.7 key test777
crypto isakmp profile vpn1

GRE tunnel through asa no pptp, l2tp, ipsec

Hello!
can't understand how to configure GRE tunnel through ASA
i have one router with public ip, connected to internet
ASA 8.4 with public ip connected to internet
router with private ip behind ASA.
have only one public ip on ASA with /30 mask
have no crypto
have network behind ASA and PAT for internet users.
can't nat GRE? cause only TCP/UDP nated(?)
with packet-tracer i see flow already created but tunnel doesn't work

A "clean" way would be to use a protocol that can be PATted. That could be GRE over IPSec. With that you have the additional benefit that your communication is protected through the internet.
Don't stop after you've improved your network! Improve the world by lending money to the working poor:

VTI tunnels vs InterVLAN

Hi everyone!
We have 2 Cisco routers - 3925 (office A) and 2921 (office B). There are VTI tunneling (with 3DES encryption), EIGRP dynamic routing (main and reserve optic channels) and 1 default VLAN #2. It`s working model which is used between 2 offices.
Now I have a task to add VLAN #3 in Office B which is used in Office A and routed to FireWall. VLAN #3 must be routed bypassing VTI tunnel. As I understand I should use InterVLAN feature on both routers. But it doesn`t work. :(
Here are configs:

Could you please assist where is the problem?

These both lines do the same things one is being explicitly value is defined and other is set for auto-discovery, however when it comes tunnel interface all you need is to set the mtu size to 1400.
one: ip tcp adjust-mss 1300
two: tunnel path-mtu-discovery
Now when an additional command, which you need to disable split-horizon on eigrp and the "x" is your process ID, which you need for spoke-to-spoke communication, to pass via the hub.
no ip split−horizon eigrp x
"If I disable these features won't i have problems with fragmentation ?"
Which is taken care by setting mtu size to 1400.
Now you set the "ip tcp adjust-mss 1380" on your physical interfaces facing toward your internal switch.
Have you tried it?
thanks

VTI tunnel & OSPF

Hi all,
I have configured VTI tunnel interfaces (tunnel mode ipsec ipv4) and OSPF on that interfaces.
VTI is encrypting all data traffic. But what about OSPF traffic?
Is OSPF traffic encrypted also or I need to configure OSPF authentication?
Thanks

OSPF exchange is already encrypted inside of the tunnel, so u don't have to use ospf-authentication. OSPF uses tunnel IP addresses for communications, and traffic flow between those two addresses is possible only throught the secure tunnel.

VTI tunnel problem

Hi all,
We have VTI tunnels between Cisco (3825 and 878) and Juniper (SRX3600).
Sometimes tunnel is going down and I should manualy shutdown and no shutdown tunnel interface to bring it up.
This is logs from Cisco:
%%crypto-4-recvd_pkt_inv_spi: decaps: rec'd ipsec packet has invalid spi for destaddr=X.Y.100.200, prot=50, spi=0xc5d07a33(3318774323), srcaddr=X.Y.100.100
%%crypto-4-ikmp_no_sa: ike message from X.Y.100.100 has no sa and is not an initialization offer
X.Y.100.100 is Juniper SRX3600
X.Y.100.200 is Cisco 3825
But I see this logs more often, than tunnel is going down!
So what is problem?
Thanks

How to set up Split Tunneling on ASA 5505

Good Morning,
I have an ASA 5505 with security plus licensing. I need to set up split tunneling on the ASA and not sure how. I am very new to Cisco but am learning quickly. What I want to accomplish, if possible is to send all traffic to our corporate web site (static ip address) straight out to the internet and all other traffic to go though the tunnel as normal. Basically we have a remote office that is using a local ISP to provide internet service. IF our connection at the main office goes down, we want the branch office to still be able to get to our corporate website without having to unplug cables and connect their computer directly to the local ISP modem. Any help with be greatly appriciated. Thanks in advance. Below is a copy of our current config.

So I tried to use the exclude way that you suggested. Here is my new config. It is still not working. The address I put in for the excluded list was 4.2.2.2 and when I do a trace route to it from the computer, it still goes though the vpn to the main office and out the switch at the main office and not from the local isp. Any other suggestions?

Hey All,
I experienced same issue with my another tunnel. Lately I came to know it was higher level of DH computation which my ASA was not able to perform and ASA reboot worked here. See the logs for tunnel which came up after reboot.

Cannot establish site-site vpn tunnel through ASA 9.1(2)

Hi,
We use ASA 9.1(2) to filter traffic in/out of our organisation. A dept within the organisation also have a firewall. They want to establish a site-site VPN tunnel with a remote firewall. We have allowed full access between the public address of the dept firewall and the remote firewall and full access between the remote firewall address and the dept firewall address . We do not use NAT.
The site-site VPN tunnel fails to establish.
The dept sysadmin has requested that we enable IPSec Passthrough. From my reading this will not make any difference as we allow full access between the firewalls in both directions. Is that correct?
Has anyone encountered issues with ASA 9.1(2) interfering with site-site tunnels?
Regards

>The dept sysadmin has requested that we enable IPSec Passthrough. From my reading this will not make any difference as we allow full access between the firewalls in both directions. Is that correct?
Yes, in that case, no IPsec-pass-through is needed. All you need is (in both directions):
UDP/500
UDP/4500 (also if you don't use NAT, the remote gateway could be located behind a NAT gateway)
IP/50
for testing ICMP/Echo
If you allowed full IP-access between these two endpoints, it is more than enough.
When they start testing, do you see a connection on your ASA. There should be at least UDP/500 traffic.
Can the two gateways ping each other?

Unable to print from HQ to Branch through the VPN tunnel between ASAs

We have site to site VPN configured between ASAs. The VPN tunnel is up and running as desired except for one printer in the subnet. the users in the Hq cannot print in the branch office printer. I have allowed the ip protocols for the printer subnet but still it is not working. When I do a packet trac the traffic for the printer is allwed through the tunnel.
Can anyone suggest what can be preventing from printing?

When other printers in the same subnet can be reached, I would first control the IP-settings of the printer. In my experience it's most likely a wrong subnet-mask or gateway.

How many IPSec Tunnels an ASA 5500 series supports

Hi All,
I tried looking in ASA documentations but unable to find out that how many IPSec Tunnels can be terminated to an ASA cluster. I have 5545 running only two IPSec Tunnels so far but need to terminate 18 sites all up and would like to confirm how many tunnels we could terminate? Is there a limitaion to it?
Thanks heaps
Shan

Yes, there is a limit. But its far away from your requirement. On the 5545-X you can terminate 2500 VPN-Peers:
