We are upgrading Cisco ASA VPN HA pair 9.5.1
We will lose the sessions/connections VPN?
This is what happens when you do not have state synchronization. Maybe you would like to enable for your next update.

Anconnect Cisco ASA VPN deployment
Hello
I have a request for information about the deployment for the ASA who must support more than 10000 clients. I understand that several ASA would be necessary for her however I was wondering what can be typical design for this? The ASA multiple is configured as vpn cluster/load balancing, etc... ?
I would if there is any design document for it. The current configuration is that a pair of ASA active / standby, I was wondering how to combine the total connection, if I need 15000 connections vpn; pairs of example 2 active / standby with vpn clustering/load balancing, etc... ?
Thank you.
You are right, that the vpn load-balancing is the technology, you need to deploy for this. With this, you can combine multiple devices to a cluster of load sharing. These devices may be different, for example two 5555 with two 5545 that would give you a total of 15000 VPN connections.
Of course, you plan for failure of the device. So you can deploy 4 * 5555 and also if an ASA is lost you yet 15000 connections (well, at least based on the datasheet; I would not push the number of connections to the limit).
You can also deploy these devices also as FO-systems for redundancy. 3 * 2 * 5555 would also give you redundancy.This is under the assumption that users connect to office even where the ASAs have one L2-connection to another which is necessary for the VPN load-balancing. If users connect through different places, then these ASAs cannot use VPN-load balancing, unless you have a L2 connection between the loacations.
If you have multiple sites, you should also think about the shared license server that could save a lot of money if your users do not always use the same gateway.
And last point: as much as possible for your AAA with a central RADIUS server set up to reduce the probability of a misconfiguration on ASAs multiples.

Configure Cisco ASA VPN client
I did some research and the answers it was supposed to be possible, but no info on how to do it. I wonder if it is possible to configure a Cisco ASA 5505/10/20 to be a customer to an existing (in this case) cisco vpn client. The reasons why are complicated (and irrelevant IMO), but basically, I need to be able to make a small network that may be on this vpn rather than on individual computers.
The vpn client is a Basic IPSec over UDP Cisco VPN to an ASA5505.
So, how to set up an another ASA to connect to it as if it were a client?
Hello
Here is a document from Cisco on the configuration, the easy ASA of VPN server and Client
Although in this case, they use a PIX firewall as a client.
http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00805c5ad9.shtml
Here's another site with instructions related to this installation program
http://www.petenetlive.com/kb/article/0000337.htm
I imagine that the site of Cisco ASA Configuration Guide documents will also give instructions how to configure it.

Static ip address linking to remote Cisco ASA vpn users
Hai, is possible to way static ip binding for users of customer remote cisco ASA of the dhcp pool that we create for users of vpn? / Please let me know your suggestions if possible. !!!
That can be done with DHCP. But your authentication server can do. If authenticate you local on the SAA, and then specify the IP address in the attributes of the user, if you are authenticating with RADIUS, you can send the "Box-IP-Address" attribute to assign the address.

Between Cisco ASA VPN tunnels with VLAN + hairpin.
I have two Cisco ASA (5520 and 5505) both with version 9.1 (7) with Over VPN and Security Plus licenses. I try to understand all the internet a traffic tunnel strategy VLAN especially on the 5520 above the 5505 for further routing to the internet (such as a hair/u-turn hairpin). A few warnings:
- The 5505 has a dynamically assigned internet address.
- The 5505 has sometimes no device turned on behind her, bringing interfaces down to the inside (which can cause problems from site to site).
- The 5520 cannot be a client of ezvpn due to its current role as a server of webvpn (anyconnect).
Let me know if I need to post my current config. Basically, I'm starting from scratch after several attempts.
Thank you!
- The 5505 has a dynamically assigned internet address.
You can use the following doc to set up the VPN and then this document to configure Hairping/U tuning
2. the 5505 has sometimes no device turned on behind her, bringing interfaces down to the inside (which can cause problems from site to site).
Make sure that the interface is connected to a switch so that it remains all the TIME.
3. 5520 the may not be a ezvpn customer due to she has current as one role anyconnect webvpn ()) server.
You can use dynamic VPN with normal static rather EZVPN tunnel.

the Cisco asa vpn processing error payload: payload ID: 1
Hello
I set up vpn L2TP by using ASDM and now I am not able to connect my Cisco ASA 5505.
It is showing the error message

Hi Nikhil,
Your config seems incomplete, command 'IPSec l2tp ipsec vpn-tunnel-Protocol' is missing, what is needed to connect L2tp try to reconfigure your firewall using the link:-

Cisco ASA VPN session reflect a public IP of different source
Hi all
I tested and managed to successfully establish the vpn on my cisco asa 5520.
On my syslog, I can see "parent anyconnect session has begun" during my setting up vpn and "webvpn session is over" at the end of my vpn session
where public ip used to establish the vpn address is reflected. However after the line "webvpn session is over", I can see other lines in my syslog example "group = vpngroup, username = test, ip = x.x.x.x, disconnected session, session type: anyconnect parent, duration 0 h: 00m23s, xmt bytes: 0, rcv:0 bytes, reason: requested user" where x.x.x.x is not the ip address used to establish my vpn for remote access, it is not related to my vpn ip address below. I am very sure that the x.x.x.x ip failed any vpn for my cisco asa5520. So why it is reflected in my logs to asa cisco? Pls advise, TIA!
Hello
Think I remember some display on a similar question in the past. Did some research on google and the next BugID was mentioned in the discussion.
113019 syslog reports an invalid address when the VPN client disconnects. -
Problem with the Cisco ASA vpn redundancy?
Hi all
I have a series ASA 5500 firewall and need to set a different peer ip for the connection of site2sitevpn. In fact, my goal is, ASA tent first pair ip of the site2site tunnel, when ASA may not reach this ip, try to reach another ip I set before. I can configure this scenerio on Cisco router with this command;
crypto map tohub 1 ipsec-isakmpset peer 10.1.1.1 default
set peer 10.2.2.2
but I wonder what can I do about ASA?
Thank you.
Best regards.
Shane,
You can configure multiple IP addresses, under the same entry of homologous set on ASA, but it works the same on IOS with preferred peer, it passes between defined peer.

Cisco ASA: Vpn SiteToSote with a backup VPN
Hi all
A partner have two VPN gateway. We have a connection on one of them, but we want to set up another tunnel for backup (if the first gateway goes down).
How can I configure my ASA to only create a tunnel with a counterpart if approves it first failure?
Thanks for the reply
You can use multiple addresses peer in your map of cryto for example.
card crypto mymap 10 set by peer
Your ASA will use try in the order that they are entered, check out this link for more details.

: endTwo things are here according to you needs.
First you encrypt all the traffic on the network 192.168.204.0/24... do you intend to send all traffic on that subnet via the VPN? If this isn't the case, specify the remote subnet instead of using all the crypto ACL.
object network LAN
subnet 192.168.204.0 255.255.255.0access-list outside_cryptomap_1 extended permit ip object LAN any
Second, you have not an exempt statement NAT so that encrypted traffic should not be translated. This statement would look like the following:
the object of the LAN network
192.168.204.0 subnet 255.255.255.0being REMOTE-LAN network
255.255.255.0 subnet 192.168.100.0Static NAT LAN LAN (inside, outside) destination static REMOTE - LAN LAN

licenses for a cisco ASA active/passive pair AnyConnect SSL
Hi all. I buy 2 5512 x ASAs is configured like a pair of active/passive as a VPN device. I need to purchase licenses for both devices anyconnect? Thank you
Licenses AnyConnect Essentials (or premium) are combined on a cluster failover ASA. Reference
So, buy once only the quantity and type of licenses you need based on your end users - not based on the number of ASAs - and they will be available at the ASA Active whether primary or secondary unit.

Transfer between Cisco ASA VPN Tunnels
Hi Experts,
I have a situation where I need to set up the transfer between two VPN Tunnels completed in the same box ASA. A VPN Tunnel will incoming traffic and that traffic should be sent to the bottom of the other VPN Tunnel to the ASA. The two VPN Tunnels are from the Internet and speak with the same IP address of the ASA peers.
Retail
Tunnel A
Source: 192.168.1.0/25
Destination: 10.1.1.0/25
Local counterpart: 170.252.100.20 (ASA in question)
Remote peer: 144.36.255.254
Tunnel B
Source: 192.168.1.0/25
Destination: 10.1.1.0/25
Local peer IP: 170.252.100.20 (box of ASA in question)
Distance from peer IP: 195.75.75.1
Can this be achieved? what configurations are needed in the ASA apart cryptographic ACL entries?
Thanks in advance for your time.
Believed that, in this case your config is good, and you can avoid using routes on your asa since it must route based on its default gateway, make sure you have good sheep in place rules and the inter-to interface same-security-interface allowed return you will need.

All,
The situation is that I'm trying to initiates a connection outside a Firewall ASA, to a destination IP address that is on the remote end of a VPN tunnel looked SAA even on the external interface. So logically slow traffic is outside to outside.
The SAA is to deny the traffic that the conversation shows the source as the destination and the outside outside.
Is there something smart, that I can do on the SAA to solve this problem?
Thank you
D
Hello
Use the following command on the ASA:
permit same-security-traffic intra-interface

Cisco ASA VPN Site to Site WITH NAT inside
Hello!
I have 2 ASA 5505 related to IPSEC Tunnel VPN Site to Site.
A 192.168.1.0/24 'remotely' inside the network and a local "192.168.200.0/24' inside the network (you can see the diagram)
The local host have 192.168.200.254 as default gateway.
I can't add static route to all army and I can't add static route to 192.168.200.254.
NAT the VPN entering as 192.168.200.1 or a 192.168.200.x free to connect my host correcly?
If my host sends packet to exit to the default gateway.
Thank you for your support
Best regards
Marco
The configuration must be applied on the SAA with the 192.168.200.0 subnet it is inside, there must be something like this:
permit 192.168.1.0 ip access list VPN_NAT 255.255.255.0 192.168.200.0 255.255.255.0
NAT (outside) X VPN_NAT outside access list
Global (inside) X Y.Y.Y.Y (where the Y.Y.Y.Y) is the ip address
If you have other traffic on the vpn through the tunnel that requires no nat, then you must add external nat exemption rules since these lines above obliges all traffic through the asa to have a nat statement.
See if it works for you, else post your config nat here.
