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
Last Failover at: 11:54:39 GMT/IST Feb 23 2012
        This context: Standby Ready
                Active time: 175394 (sec)
                  Interface ctxb-inside (x.x.x.165): Normal (Waiting)
                  Interface ctxb-outside (x.x.x.165): Normal (Monitored)
        Peer context: Active
                Active time: 11390663 (sec)
                  Interface ctxb-inside (x.x.x.164): Normal (Monitored)
                  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.
Here is the reference guide FYI:

Transparent mode/firewall mode in a multiple context asa5520

Hello,
Is it possible to have a transparent mode on CONTEXT_A and firewall/route mode in CONTEXT_B in a single ASA
5520?
thanks.

Is there any document to support this? I would be getting my hands on a ASA pretty soon hope to test this feature out.

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.

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.

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.

ASA 5520 with multiple contexts becomes unresponsive

Hi all. We have encountered a perculiar problem with a pair of our ASA 5520 firewalls with 2 contexts(each context being active on different ASA). What we are seeing is that sometimes when we have a sudden increase of inbound traffic(mostly HTTP) towards servers behind the firewalls they seem to go bananas for the lack of a better expression.
They become unaccessible via ssh and the traffic drops significantly. The problem is mitigated by disabling one of the monitored interfaces for failover(on one of the switches the firewall is connected to) so that both contexts become active on one firewall. After that the firewalls seem to come to their senses and we can enable the switch interface again but sometimes one of the pair needs to be rebooted to restore full funcionality.
To us it seems like there is a problem with failover and contexts but we haven't been able to pin it down. The failover link isn't stateful and when we tested the failover it works fine both ways with each ASA taking up the full load when the other ASA of the pair is not available.
Did anyone come across a similar situation with their firewalls?

We are using ASA version 8.2(5).
The configuration of the failover is:
failover
failover lan unit primary

Stateful Failover Logical Update Statistics

When I disabled the monitored interface it was always the same interface altough I believe the same effect could be achieved with disabling any of the monitored interfaces.
As for memory and CPU when it happens I cannot access the units to get a reading but I asume it's through the roof.
The thing that troubles me more is that the situation persists when the load drops and I have to perform the solution from the first post. One would assume that with the drop of the load that both firewalls would start to behave normally.
And I see that I haven't mentioned it before but when the load drops both units continue to handle traffic normally but I sometimes see as a side effect that I cannot SSH to one of the units. That unit usually has to be restarted.

Transparent firewall with CSC

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 :

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.

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!

IDSM2 with FWSM with contexts

Hiya,
I'm not a Security guy so keep it simple!
If deploying a FWSM with multiple contexts, and you have an IDSM-2 installed:
Does the IDSM be split into contexts to match the FWSM contexts
If not, does it monitor the backplane traffic and it does not matter or care about the multiple contexts.

Hi .. by looking at your diagram .. I suggest to try placing the IDSM-2 so that traffic is inspected after the firewall policies have been checked otherwise you might end up inspecting traffic that will be blocked by the firewall anyway. You also need to create what is called boundary VLANs so that your IDSM bridges the traffic between the inline VLANs... Confused ..?
It gets a bit "blue" when you try inspecting inline on a module. For example lets say you have Context1 with Interfaces VLAN10 (outside) and VLAN20 (inside). You would have to create another VLAN30 (boundary VLAN). You then need to allocate the devices ONLY ( not the ASA's interface ) from VLAN20 to VLAN30 ( Only change VLAN membership and not the IP scheme ). Next on one of the IDSM-2 sensing ports you need to create a VLAN inline pair ( it uses subinterfaces ) which bridges VLAN20 <-> VLAN30. In that way traffic to/from your inside devices will travers the IDSM-2 before reaching its destination
I suggest you to create a test context, allocate the 2 VLANS, Create the VLAN inline pair on the IDSM-2 and test.. Once you are happy you can replicate the same configuration for the production contexts.
Below a brief example what you need to do for each context
sensor# configure terminal
sensor(config)# service interface
sensor(config-int)# physical-interfaces GigabitEthernet0/2
sensor(config-int-phy)# admin-state enabled
sensor(config-int-phy)# description INT1
sensor(config-int-phy)# subinterface-type inline-vlan-pair
sensor(config-int-phy-inl)# subinterface 1
sensor(config-int-phy-inl-sub)# vlan1 52
sensor(config-int-phy-inl-sub)# vlan2 53
sensor(config-int-phy-inl-sub)# description pairs vlans 52 and 53
sensor(config-int-phy-inl-sub)# show settings
subinterface-number: 1
description: VLANpair1 default:
vlan1: 52
vlan2: 53
sensor(config-int-phy-inl-sub)# exit
sensor(config-int-phy-inl)# exit
sensor(config-int-phy)# exit
sensor(config-int)# exit
Apply Changes:?[yes]:
I hope it helps ... please rate it if it does !!!

Backup or redundant ISP with FWSM and security contexts...

Hello guys,
I am in a middle of a dessign problem. We have 2 ISP, and we have a FWSM running multiple contexts, my context that is receiving all the static translations for all my published servers is the one where i want to configure default gateway tracking (so it can go out to an "outside2" interface in case the primary fails) and use the second ISP link for internet access and static nat. Just the exact way the ASA works.
I am not quite sure it works with FWSM.
Thanks a lot!
emilio

Hello Emilio,
You cannot configure SLA monitoring on the FWSM at this moment.
Maybe in the future this great feature will be added to this modules.
I know the 6500 supports it so you can try to set it up there.

Julio

ARE-1 creation with reference to multiple excise invoice

Hi,
In J1IA101 enter the first excise invoice in the releavnt field and hit enter and once this excise invoice is updated in the tab,excise invoice summary enter the next excise invoice in the same field as before and hit enter.In this manner you can enter as long as the sold to party and Export type are the same.

How do i set up a slideshow with pictures from multiple iphoto libraries?

How do i set up a slideshow with pictures from multiple iphoto libraries? One library is in my Macbook Harddrive, the other 2 libraries are in an external harddrive. Thank you!!

You can't, simply. An iPhoto Slideshow can only draw from a single library, so you'll need to get all the images into one.
Alternatives to iPhoto's slideshow include:
iMovie is on every Mac sold.
Others, in order of price:
PhotoToMovie $49.95
PulpMotion $129
FotoMagico $99
Final Cut Pro X $299
It's difficult to compare these apps. They have differences in capability - some are driven off templates. some aren't. Some have a wider variety of transitions. Others will have excellent audio controls. It's worth checking them out to see what meets your needs. However, there is no doubt that Final Cut Pro X is the most capable app of them all. You get what you pay for.
