Botnet Filter with multiple Context Mode

We used the Botnet Filter in Single Context Mode for a long Time. Now we converted to multiple Context Mode and the Database is no longer updated. In the system Context I can See the update settings but when I try to update the result is always "no DNS server". Since the system context has no interfaces there are no DNS settings etc.
How should be the Botnet Filter configured in Multiple Context Mode?
Thanks for any response in advance.

Failure when FWSM in transparent mode with multiple contexts

hi experts,
We have two FWSMs working in active/standby state, configured with multiple contexts in transparent mode. and the "outside" and "inside" interfaces for each context are in same subnet.
Now we have one FWSM broken and the RMA part can't arrived in short time, so we have the risk that the sencond FWSM could be failed as well. In the worst case if the two was broken or powered off simultaneously, i wonder that if the communications between multiple contexts could be ok???
thanks in advance.

The software requirements for Cisco Secure ACS are dependent on the type of Extensible Authentication Protocol (EAP) desired. For full support of all the EAP types including EAP-Flexible Authentication via Secure Tunneling (FAST), use release 3.2.3 or higher.

Are VPN Clients supported in multiple context mode?

Hi,
Recently our company has bought two Cisco ASA 5515-X firewalls for at our datacenter. I am new on configuring a Cisco ASA but sofar things are looking good. I have configured them both with HA (active/active) in multiple context mode. Currently they host two security contexts.
I want to configure VPN Client functionallity for Remote Access. As far as I know they come with two user licenses. But there is no VPN Client wizard available and I can't find a way to enable it.

Hi,
No form of VPN Client is supported when you are using an ASA in Multiple Context mode.
The only type of VPN supported in the newer 9.x softwares is L2L VPN / Site to Site VPN
This might answer the VPN Licensing related question

I never seem to remember it exactly myself even.

Explain about transparent mode, single mode, multiple context mode

You can explain about the differents of transparent mode, single mode, multiple context mode in ASA 5500? Thank you very much.

Great question. Hope the below helps:
Transparent Mode: In this mode, the ASA will filter traffic without requiring L3 on the ASA. This means that in your config you will not put IPs on the interfaces to be used for traffic filtering. Thus, filtering is transparent to the traffic as the traffic isn't directly routed to the firewall. Think of it like you have a server plugged into a switch. In transparent mode, you place the ASA between the server and the switch and no configuration change is required to the server. In routed mode, you place the ASA in the same physical location between the server and switch, but have to change the server to use the ASA as a default gateway.
Single Mode: Default mode of an ASA. The ASA acts as a single firewall and all interfaces are provisioned to be managed through a single firewall configuration.
Multiple Context Mode: The ASA is split into multiple virtual configurations. With the ASA now virtualized, you provision the physical interfaces on the ASA to the virtual firewall configured. Each context has it's own configuration seperate from the rest of the firewall. Multi-context is meant for enterprises to invest in a single piece of hardware and scale it for use as multiple security devices.
Hope this helps. Let me know if you have anymore questions!

Remote Access VPN Support in Multiple Context Mode (9.1(2))?

Hi Guys,
I am currently running two Cisco ASA5520 (ASA Version: 9.1(2)) firewalls in Active/Standby failover and was contemplating the option of migrating my remote access VPN to these firewalls. However seeing that the new IOS now support mixed multiple context mode and dynamic routing. Is it safe to ask whether or not Remote Access VPN is now support in this IOS upgrade?
Multiple Context Mode New Features:
Site-to-Site VPN in multiple context mode | Site-to-site VPN tunnels are now supported in multiple context mode.
New resource type for site-to-site VPN tunnels | New resource types, vpn other and vpn burst other, were created to set the maximum number of site-to-site VPN tunnels in each context.
Dynamic routing in Security Contexts | EIGRP and OSPFv2 dynamic routing protocols are now supported in multiple context mode. OSPFv3, RIP, and multicast routing are not supported.
New resource type for routing table entries | A new resource class, routes, was created to set the maximum number of routing table entries in each context. We modified the following commands: limit-resource, show resource types, show resource usage, show resource allocation. We modified the following screen: Configuration > Context Management > Resource Class > Add Resource Class.
Mixed firewall mode support in multiple context mode | You can set the firewall mode independently for each security context in multiple context mode, so some can run in transparent mode while others run in routed mode. We modified the following command: firewall transparent. You cannot set the firewall mode in ASDM; you must use the command-line interface. Also available in Version 8.5(1).
Regards,
Leon

Hey Leon,
According to the ASA 9.1 Configuration Guide, Remote Access VPN is not yet supported with version 9.1(2). Only Site-to-Site VPN support in multiple context was introduced with release ASA 9.0(x). This was mentioned in the 9.0(x) release notes.

Dennis

SSLVPN/webvpn in multiple context mode?

We already know that ASA 9.0 supports site-to-site VPN in multiple context mode. But remote access VPN isn't supported. Obviously, SSL-VPN is a very important feature for most multi-tenant deployment scenarios where each context acts as a border firewall towards the Internet for each tenant. The alternative to terminate all tenant remote-access VPNs in one context means that each tenant would have to be routable from the ASA, which of course isn't a reasonable requirement in most cases.
So, what I'd like to do is to deploy an ASA cluster, and provide remote access VPNs for each tenant, where the connectivity for each remote access group can be addressed with whatever IP address space, and that goes into it's own VRF in the back-end.
As far as I can tell, this isn't doable with the ASA, since multiple context mode prohibits the use of remote access VPN, and I can't think of any other work-around than either having individual firewalls running in single context mode for each tenant, or demand that all tenants are interoperable routing-wise and configure a separate ip address pool in a single context mode for each tenant.
Essentially, there's no good way to implement this with multiple virtual firewalls, using cisco firewalls? Or am I missing something?

If you set up a pair of single-context ASAs for VPN termination, configure a group policy per customer and use the 'Restrict access to VLAN' feature, you could separate customers' traffic and still just use one FW pair for all customers. This pair would connect to the same switch infrastructure as your multi-context edge firewall and thus allow a consolidated solution.

Active/standby in multiple context mode

is active/standby configuration possible in multilple context mode? i cannot find an article regarding this matter.

Hello John,
It is available
Actually the ones you need are the regular ones (documents) as the ASA will trigger failover if one of the context fail
Important Notes
For multiple context mode, the ASA can fail over the entire unit (including all contexts) but cannot fail over individual contexts separately.
. Active/Standby Failover is available on units that run in either single or multiple context mode. Both failover configurations support stateful or stateless (regular) failover.
VPN failover is not supported on units that run in multiple context mode as VPN is not supported in multiple context. VPN failover is available only for
Active/Standby Failover configurations in single context configurations.
With this I think you are ready to start configuring it:

How to filter with multiple selection on a single column on external list, currently only one filter per column is available.

I have external list where i want to apply multiple filter for every column like we do in Excel spreadsheet - we can filter a spreadsheet column by selecting multiple checkbox for every column. I am using Sharepoint 2010
Is this possible in sharepoint 2010? Any idea how to acheive that?
Thanks in advance.

Hi Rahul,
According to your description, my understanding is that you want to use filter with multiple values on a column of an external list in SharePoint 2010.
Per my knowledge, there is not an OOB way to achieve it. As a workaround, you can custom the web part to implement it. There is an articles for your reference:
http://blogs.telerik.com/aspnet-ajax/posts/13-11-05/add-excel-like-multi-select-filtering-to-your-asp.net-datagrid
In addition, you can use a third party solution to achieve it, please take a look at:

Support IPSec VPN Client in ASA Multiple Context Mode

I've looked at under "Cisco ASA Series CLI Configuration Guide, 9.0" on "Configuring Multiple Context Mode", it says
"IPsec sessions—5 sessions. (The maximum per context.) ". Does it mean in ASA Multiple Contest Mode support IPSec VPN Client? I just want to confirm it because I can't seem find any doc that clearly spell it out. I'll appreciate anyone who can clarify it.
Thank Jason.
( Please direct me to the right group if I'm not for the first time I post it in the Cisco support forum)

Dynamic Routing Protocol Support in Cisco ASA Multiple Context Mode

                   Dear Experts,
Wold like to know whether dynamic Routing Protocol Support in Cisco ASA Firewall Multiple Context Mode. If yes then please provide OS version and Hardware Model of Cisco ASA Firewall. Appreciate the quick response. Thanks.

Hi,
Check out this document for the information
http://www.cisco.com/en/US/docs/security/asa/roadmap/asa_new_features.html#wp93116
Its lists the following for software level 9.0(1)
Multiple   Context Mode Features
Dynamic routing in Security   Contexts
EIGRP and OSPFv2 dynamic   routing protocols are now supported in multiple context mode. OSPFv3, RIP, and multicast routing   are not supported.
Seems to me you would need some 9.x version to support the above mentioned Dynamic Routing Protocols.
I don't think its related to the hardware model of the ASA other than that it requires a model that supports Multiple Context Mode. To my understanding the only model that doesnt support that is ASA5505 of the whole ASA5500 and ASA5500-X series.
Hope this helps

Multiple context mode and Active Active

Hi Everyone,
ASA in multiple context mode works as active active mode.
ASA has 2 contexts admin and x.
We have 2 physical ASA say ASA1 and ASA2 .
Under system context we have hostname ASA
When i ssh to ASA1 it brings the ASA/admin mode.
sh failover shows
sh failover shows
This host: Primary
This host: Primary
When i try to login to ASA 2 it brings me to ASA/x prompt.
sh failover shows
This context: Active
Peer context: Standby Ready
Need to know is there any way that i can login to other physical ASA?
i hope my question makes sense.
Message was edited by: mahesh parmar

Hi Mahesh,
To it seems that you are logging to different contexts in these 2 cases.
Normally an admin always logs to the "admin" context IP address owned either by the primary IP address for the Active unit or the secondary IP address for the Standby unit.
So what I would suggest you do first is that you go to the context "admin" and issue the command "show run interface"
Then go to the context "x" and issue the command "show run interface"
Now check the IP addresses on the interfaces.
Especially the interface on the "admin" context should contain an IP address for both of the ASA units. Check the interface IP address which originally lead you to the "admin" context.
For example
ip address 10.10.10.1 255.255.255.0 standby 10.10.10.2
If the above were true you would connecto the IP address 10.10.10.1 when you wanted to connect to the Active unit and use the IP address 10.10.10.2 when you wanted to connect to the current Standby unit

ASDM_HANDLER problem on multiple context mode

Hello,
Has any anybody seen this error?
On the firewall multiple context I used to jump from one context to another, but now when I log in to the admin context and I try to jump to another context I receive this error. Could no find any bug on release notes for that.

Hi,
I have not personally seen this error before. Though I don't use ASDM that much anyway. We used to have FWSMs in multiple context mode and now have ASAs running multiple context mode and I have never seen this.
Have you checked the situation (as the error message suggests) from the CLI of the ASA to see if there is a lot of ASDM sessions in the "admin" context of the unit?

Hi Teck Yong Ng,
I am not sure about your problem, but normally what happens when we install two databases on the same host is there will be conflict between the ports connecting to the database.
In your case the second system database might also have the same port number which you have for the first system.that is why i think you are facing this issue.
Try to look at the port numbers.

ACE with multiple context

hi,
i've 4 virtual context in my ACE configuration.it's possible to use the same real server in multiple context?2 context are configurated in one-arm mode
and 2 in bridge mode.
tks all
Aghibear

you could use one context as the default path - selecting this contect as the default gateway.
Then the other context uses client nat to guarantee that the response comes back.
I don't know if there is a specific example for what you want to do.
You can check sample configs from :

Transparent firewall with failover with multiple contexts

                   I am running 8.4(2) on ASA5585s. They are in mulitble context mode and set to transparent firewall with active/active failover. When I do a sh failover in a context I see 2 of my interfaces are (waiting). I have a BVI and these are the ip addresses on the interfaces in he "sh failover" below.
Failover On

        This context: Standby Ready

                  Interface ctxb-outside (x.x.x.164): Normal (Waiting)
Why are the interfaces in (waiting)?

Are you able to ping between the interfaces? ie: can you ping x.x.x.165 from x.x.x.164 and visa versa? If you are not able to ping it, that means there is no connectivity between the 2, hence the status is in Normal (Waiting) because it has not received the hello packet on that corresponding interface.
