ASA and VTI configuration

Good morning experts,
My experience with ASAs over the last few years has been limited so I am not up on all of the newer features that they offer. I know in the past that ASAs did not support any type of tunnel interfaces and thus did not support a VTI configuration like you can do on an IOS router.
My problem is that I need to build a VPN tunnel between a few ASAs and a Juniper netscreen which many networks on each side that can not easily be summarized. Being able to build a route based VPN on the ASA would be very helpful as the crypto map could essentially be all zeros. Without this configuration, crypto IDs on both sides are going to get very complication very quickly.
I can't seem to find any info on VTI configuration for the ASA which leads me to believe it doesn't exist. However a guy I work with that uses ASAs daily firmly believes that after version 8.4 this configuration is supported.
Can anyone confirm please?
Elton

Dear Karthik ,
I do not think the posted link contain what is elton looking for , actually I have few juniper firewalls and looking to replace them with ASA's but the problem is ASA did not support tow of our main requirements which is Route Based VPN through VTI , and GRE tunneling
I do not why Cisco did not support those features on ASA till now (as per my knowledge) most of firewall vendors support that

What does the 'rtcli async executor process' process do on a Cisco ASA and why would it cause high CPU load?

I noticed that the CPU on our ASA had jumped from around %4 to 30% consistently a few weeks back. The process below seems to be causing the load, but I can't find any information on what it does and how to resolve the issue.
ASA# sh proc cpu-usage sorted non-zero

A little more background that has me concerned is that I have the exact time when the jump occurred. Since that time, I've lost ssh access to the ASA and can only access it via Telnet internally or the ASDM. I checked the certificates and a new one was generated exactly when the spike occurred. I am unsure wether or not that was a system triggered certificate generation, or if I have a security issue I need to address. Heartbleed maybe??
Any insight would be greatly appreciated.

Sorry I wasn't clear, but when I was asking about "not a lot of traffic", I was wondering about actual volume passing through the 2811.
When I asked about "kind of tunnels", I was wondering about how they are configured. E.g. GRE or IPSec/GRE or VTI, encryption options, other tunnel interface options.
Perhaps the easiest way to check for fragmentation, is packet analyze the traffic passing through the 2811.

Site-to-site vpn with 2 asa and home router

I am trying to establish a site-to-site vpn between 2 ASAs and am able to get the tunnel to establish and can get connectivity from the remote end of the connection to the local side. However, traffic from the local side is not able to get to the remote end. We have 2 ASA 5505 establishing the tunnel, on the remote end there is a linksys home router forwarding all traffic to the ASA outside interface on a private subnet. Our layout is as follows.

ISAKMP Phase 1 dying for Site to Site tunnel between ASA and Fortigate

      I am facing strange issue on my asa and client Fortigate fw.
We have site to site tunnel with 3des and sha and DH-5 on asa
3des sha1 and dh-5 on Fortigate.
Tunnel came up when configured after some time it went down and it is throwing below errors. Please
some one help me here.

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.

MS NLB with ASA and Static NAT from PUP to NLB IP

Hi all,
I am trying to get MS NLB up and running. It is almost all working. Below is my physical setup.
ASA 5510 > Cat 3750X >2x ESXi 5.1 Hosts > vSwitch > Windows 2012 NLB Guest VMs.
I have two VMs runing on two different ESXi hosts. They have two vNICs. One for managment and one for inside puplic subnet. The inside puplic subnet NICs are in the NLB cluster. The inside public subnet is NATed on the ASA to a outide public IP.
192.168.0.50 is the 1st VM
192.168.0.51 is the 2nd VM
192.168.0.52 is the cluster IP for heartbeat
192.168.0.53 is the cluster IP for NLB traffic.
0100.5e7f.0035 is the cluster MAC.
The NLB cluster is using MULTICAST
I have read the doumentation for both the ASA and CAT switch for adding a static ARP using the NLB IP and NLB MAC.
For the ASA I found
http://www.cisco.com/en/US/docs/security/asa/asa84/asdm64/configuration_guide/mode_fw.html#wp1226249
ASDM
Configuration > Device Management > Advanced > ARP > ARP Static Table
I was able to add my stic ARP just fine.
However, the next step was to enable ARP inspection.
Configuration > Device Management > Advanced > ARP > ARP Inspection
My ASDM does not list ARP Inspection, only has the ARP Static Table area. Not sure about this.
For the CAT Switch I found
http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_example09186a0080a07203.shtml
I added the both the ARP and Static MAC. For the static MAC I used the VLAN ID of the inside public subnet and the interfaces connected to both ESXi hosts.
On the ASA I added a static NAT for my outside Public IP to my inside pupblic NLB IP and vise versa. I then added a DNS entry for our domain to point to the outside public IP. I also added it to the public servers section allowing all IP traffic testing puproses.
At any rate the MS NLB is working ok. I can ping both the Public IP and the Inside NLB IP just fine from the outside. (I can ping the inside NLB IP becuase I'm on a VPN with access to my inside subnets) The problem is when I go to access a webpade from my NLB servers using the DNS or the Public IP I get a "This Page Can't Be Displyed" messgae. Now while on the VPN if I use the same URL but insied use the NLB IP and not the Public IP it works fine.
So I think there is soemthing wrong with the NATing of the Public to NLB IP even tho I can ping it fine. Below is my ASA Config. I have bolded the parts of Interest.
Result of the command: "show run"

Any help would be great! I think the issue is in teh NAT as I am able to access NLB IP from the outside and could not do that before adding the Static ARP stuff.
Thanks,
Chris

Also If I change to NAT from the public IP to the NLB IP to use either one of the phsyical IPs of the NLB cluster (192.168.0.50 or 51) it works fine when using the public IP. So it's definatly an issue when NATing the VIP of NLB cluster.

Packet Loss between ASA and 871

We are running a Cisco ASA 5505 and remote clients are 871's. We currently use a EasyVPN configuration between the single ASA and our 13 871's.
Today (1) out of the (13) tunnels is experiencing packet loss. I have power cycles the broadband router on the 871 end and the 871 and the situation still exists.
Does anyone know what would cause this and how to troubleshoot it?
Thanks,
Jason

Have you contact broadband provider on the 871 side to rule out any issues on the link? what broadband ADSLAM pppoa? start first rulling out physical issues WAN interface, LAN interface stats and work your way up, is this is something that suddenly developped? from what you post indicates it seems this tunnel have been fine, it could be broadband link issues but fist investigate with provider to go the next step.
what do you see in 871 router logs in terms of links, turn on logging informational before staring debugg proceedures.

Best practices for using Normalizer in ASA and in AIP-SSM

Both PIX OS 7.x and IPS 5.x software have a concept of "traffic normalization". PIX OS on ASA can do virtual reassembly, IPS on SSM (so far as I know) can do physical reassembly and fragmentation of IP packets. Also, both ASA and SSM can do TCP normalization. For example, they both can "check inconsistent retransmissions" and protect against "TTL evasion attacks". I realize that PIX OS has only basic normalization functions and the SSM is much more configurable.
The question is: what are the best practices here? Is it better to disable some IP/TCP PIX OS checks / IPS signatures on ASA and/or SSM? Is it better to use just SSM for traffic normalization? Does anybody has personal experience here?
Also, there is a BugID CSCsd04327 - "ASA all out of order packets are dropped when sending to ssm"
"When ips ssm is inline slowness is reported. show service-policy shows that the number of out of order packets reported match exactly the number of no buffer drops (even with queue-limit option). Performance hit is not the result of tcp normalization (on IPS 5.x ssm) in this case, but rather an issue with asa normalizer."
To me it seems to be more logical to have normalization function on the firewall, but there may be drawbacks in doing this.
So, those who're using ASA with SSM, please share your experience.
Thx.

Yes, this is almost correct ;)
TCP SRP (Stream Reassemly Processor) is turned OFF on the SSM and cannot be enabled, contrary to 4200 appliances, but IP FRP (Fragmentation Reassembly Processor) is functioning on the SSM.
The testing of 7.2(1) shows the following:
When you configure "policy-map" to send packets to the SSM the "tcp-map" parameter "queue-limit", which has the value of zero by default, is set to an X (the X is unknown). This means that the ASA now only accepts the TCP segments which are sent in the correct order. More specifically, the gaps in SEQs are not allowed anymore. When for example, the ASA receives a TCP segment which has a SEQ within the window, but the previous TCP segment has been lost, it sends an ACK to the sender to enforce retransmition of the lost segment. As a result the sender retransmits both segments. Only after that the ASA forwards both segments to the SSM. This basically means that SSM always sees in-order TCP segments. That it is why SRP is not needed on the SSM.
There are at least two problems however.
The first problem is the performance impact.
ASA now acts almost like a proxy. And, so far as I know, it doesn't support SACK (Selective ACKs). First, when the ASA does TCP SEQ randomization it doesn't change SEQ values within the SACK TCP Option. This simply breakes SACK. Second, even if you turn randomization mechanism OFF, then, I believe, the ASA will not selectively ACK the lost TCP segments, as it simply doesn't support this mechanism.
The second problem is THE SECURITY HOLE.
By default the ASA doesn't check TCP checksums. The 4200 appliances do check by default. But as we now know the SRP is turned OFF on the SSM... So, this means that SSM module can easily be evaded. The hacker only needs to mix attacking traffic with the random TCP segments that have bad TCP checksum. The SSM module will see the mixture of the two and will not recognize the attack. The target host will drop TCP segments with the bad checksums and see only attacking traffic... This has been successfully verified in the lab.
Of course, this security hole can be closed with the "tcp-map" parameter "checksum-verification", but it will definitely has performance impact.
The last note: All of the above has never been documented by Cisco. So, use at your own risk, etc.
I hope, you will read this message, Marcoa. All of this MUST be documented. Once again, the default behaviour of the ASA opens up a big security hole.

ASA and plusnet fibre

Hi,
One of our sites has just upgraded to fibre broadband, the fibre box provided is a BTopenreach.
I have configured an ASA 5505 with a Zyxel NBG5615 router.
I have tested the router without the ASA which traffic works but when i add the ASA traffic does not pass through.
I have turned NAT and Firewall off on the router.
I have tried two different ASA one is 8.2(1) and the other 9.0(1).
Any assistance will be appreciated.
Ash

Hi,
Not really enough information to go on.
I guess one question would be does the ISP provide the IP addresses with DHCP or do you staticly configure your devices WAN interface?
Is there a need for the Zyxel infront of the ASA? Could you simply attach the fibre to the ASA (with the device the fibre is connected to). I am not sure what kind of device it is that your fibre is connected to. If it was possible to only use the ASA as a device doing routing/NAT/ACL then I would imagine the setup could be really simple. Now the problems might be more related to having 2-3 devices behind the fibre and having configuration error somewhere there that prevents normal traffic flow.
We would really need to know how the devices are configured to be able to help at all.

ASA 55xx Series configuration

1) Is there any support provided for uploading our own custom login pages to the ASA appliance? e.g. flash embeded html page
2) Can the ASA appliance be configured to redirect the authentication to a specific URL (custom web server which will do some means of authentication) and if successfully authenticated then webserver will post the credentials back to the appliance. This way it will support multi-factor authentication.

Yes, I think there few support will provide for uploading our own custom login pages to the ASA appliance and you can redirect the authentication to a specific URL: for more information please click following URLs:

Can't get L2L VPN up between ASA and Fortinet (IKEv2)

Issue bringing up VPN between ASA and Checkpoint - HELP

Hi all
We are having major issues bringing up a vpn between our ASA and third party checkpoint, it seems if the checkpoint initiates the connection it works, but if we initiate it from the ASA it doesnt come up.
on the ASA I see the following
any ideas what this is ?

IP = 159.50.93.1, IKE MM Initiator FSM error history (struct &0x79c4bb68) , : MM_DONE, EV_ERROR-->MM_WAIT_MSG2, EV_RETRY-->MM_WAIT_MSG2, EV_TIMEOUT-->MM_WAIT_MSG2, NullEvent-->MM_SND_MSG1, EV_SND_MSG-->MM_SND_MSG1, EV_START_TMR-->MM_SND_MSG1, EV_RESEND_MSG-->MM_WAIT_MSG2, EV_RETRY

Phase 2 failures means several things:
Encryption domain (interesting traffics) fail to match. Checkpoint tends to supper net network together, by design,
Phase 2 parameters such as ESP, PFS and seconds timeouts do not match.
Why don't you put in relevance configuration on the ASA and if possible, ask the checkpoint firewall guy to do the following on the firewall:
- output of "uname -a" and "fw ver"
- is this Nokia, Windows or Secureplatform Checkpoint?
- run the following commands on the firewall: "debug ike off", "debug ike trunc" and send you the ike.elg file. That file can be decoded with the IKEView.exe and it will tell you exactly where things are wrong.
Disable/turn OFF kilobytes timeouts is not the solution.

IPSEC b/w ASA and Router --- with nat stuff

I need help regarding the following issue..
An asa is connected to a router which is connected to the internet.
A vpn must be established b/w ASA and a router that is over internet . The ASA is not directly connected to the internet. It is connected to a router which nat the Asa outside ip to a static global IP .
All i need to know is that do need any special configs for this . or its the same as if ASA would have been directly connected to the internet

In order to configure a LAN-to-LAN tunnel between a Cisco IOS? router and an Adaptive Security Appliance (ASA), these configurations are required on the ASA:
Configure the crypto ipsec command in Phase 2.
Configure the isakmp policy command.
Configure the nat 0 command and the access-list command in order to bypass NATting.
Configure the crypto-map command.
Configure the tunnel-group DefaultL2LGroup command with group information

How to use the private subnet between ASA and Router

Guys,
Here is the context:
I am connecting to 2 ISPs for load sharing traffic coming from my private network.
The 2 links from the ISPs terminate in the router which connects to an ASA via a private subnet, back to my private network.
I have configured PBR in the router, to prefer ISP1 for trafic coming from my internal servers X, Y, Z (public addresses, no need for the ASA to translate). The router should send any other traffic coming from the rest of my private address space, servers W, V, U (after translation by ASA) to ISP2.
So far so good. The default route defined on ASA points to the internal LAN interface of the Router (private ip address). How can I route this subnet used between the ASA and Router? Being a private address I have to translate it to something (public) before the router can send it out. But translate to what?
Alternatively I could use a public subnet. But I do not have any.How do I get aroung this?
Regards
Ndaungwe

You have IP addresses on the direct interface links to the ISP's?? You ccould use those IP addresses with NAT overload.

Connection dropped between ASA and router

Hi,
Last night Internet traffic was going from my 2811 router to the Internet via my ASA 5510 (as it should do and in accordance with my route-map policy) but, when I came in this morning, traffic wasn't going via my ASA as my route-map policy specified, it was going straight to the Internet via my Gateway of Last Resort (an SDSL router). When I did a ping between the ASA and the 2811 router, traffic started to be routed via the ASA again, as specified by the Route-Map policy. Does anyone know what caused this to happen?
Thanks,
Jaime

Ensure your ACL configured properly in your device or may be you did any changes recently.

IPSec ikev2 between ASA and Cisco Router

Hi,
i try to do IPSec with ikev2 (SHA2) between ASA and Cisco Router, without success. Any one can help me ?
- Remote site (Router) with dynamic public IP -> Dynamic crypto map on the ASA
- Authentication with Certificats
- integrity sha2
I try a lot of configurations without success.
Thanks for your help.
Mic

The more secure ike policy should have the higher priority which is a smaller number. So I would configure there the following way (policy 30 only if really needed):
crypto ikev1 policy 10
authentication pre-share
encryption aes-256
hash sha
group 5
lifetime 28800
crypto ikev1 policy 20
authentication pre-share
encryption aes-256
hash sha
group 2
lifetime 28800
crypto ikev1 policy 30
authentication pre-share
encryption aes
hash sha
group 2
lifetime 43200
The Cisco VPN Client is EOL and not supported any longer. And yes, by default DH group 2 is used. But that can be configured by a parameter in the PCF-file.
There are two (three) better options:
Best option with very little needed configuration:
Move to AnyConnect with TLS. AnyConnect is the actual Cisco client that is also supported with Windows 8.x. The legacy IPsec client isn't.
Best option with a little stronger crypto but more configuration:
Move to AnyConnect with IPsec/IKEv2.
Move to a third-party client like shrew.net. I didn't use that client since a couple of years any more, but it's quite flexible and also has a config for a better DH-group.
For option 1) and 2) there is an extra license needed, but thats not very expensive.
