Cisco WAN :: 5520 - Active / Passive ASA With Redundant ISP Connections

Apr 25, 2012

Currently we are using a single connection to our ISP and in the coming months will be moving to a two seperate connections (to same ISP). In our current setup we utilize active/passive ASA's (5520, single context) and would like to utilize that going forward as well, the reason being is our DMZ's all hang off of these ASA's and we have fiber connectivity between our datacenters.Our main datacenter and DR Datacenter are basically one big LAN with fiber between them, so we have our DMZ networks at both locations currently with both terminating in our ASA's. That way if the ASA at our current site fails the DMZ's are still accessible via the secondary firewall at our DR facility.

May 24, 2011

I have the following Setup, Two Cisco ASA 5520 needed to be  configured in HA Active/Passive. The Firewalls includes also AIP module. Does the ASA 5520 will internally make the AIP modules also HA Active/Passive? Is there a document regarding the issue? Is there a seperate license for the AIP modules for HA scenario?

Cisco Firewall :: ASA 5520 - Interface Reconfiguration In Active / Passive Failover

Dec 20, 2011

Currently l have two ASA 5520's in a active/passive failover scenario.  Currently the interfaces for the inside and outside are fixed at 100/FULL.I want to repatch them into GigE ports setup as Auto Negotiate.Is there anyway of keeping the connections through the firewall active in this type of scenrio or will l have downtime disconnecting and repatching?  or could l possibly disable failover and reconfigure each ?

Cisco Firewall :: Show Active TCP Connections In ASA 5520?

Jun 5, 2013

how many active TCP sessions my ASA has but having a hard time finding this information.  When I do "show conn count" from the CLI it shows what I'm guessing is a sum of both TCP and UDP.  Is there any way to get just the TCP connections?

Cisco Firewall :: Cannot Use FTP Passive / Active Of ASA5505

Sep 12, 2011

Users cannot download some files from a FTP in a software over VPN Explanation users work with a program and inside the program they download claim (the software goes to the FTP and download the file)
But the program returns an error 3018 in FTPGET. If the user goes to the old PPTP VPN it works like a charm  so the problem is the Cisco VPN.
I cannot post my complete config but we use the filter vpn value to associate a special access-list to a user.
The user that has this problem has this as an access-list.
access-list 201 extended ip permit
I've made some research and i've added this info
policy-map global_policy
class inspection_default
Inspection ftp
Still doesn't work. 
I have to  add that normally the internal network is 2.0 and not 202.0 but since we have user with 2.0 at home we had to do this.
So when a user sends a request to 202. the cisco fowards it to the Juniper inside the network and it translate it back to 2.0 Also that is the ONLY thing that doesn't work.  The client can work all day on that program and it will work #1 exept when she does the claims
I am also been working on this VPN for 2-3 months without any problems.

Cisco Firewall :: ASA 5510 Active / Passive Failed

Jan 12, 2012

i have a problem with a Failover Pair of 5510. The Boxes run with the software version 8.2.5.
If the Active ASA goes down, the Standby ASA switch to Active.
If i switch on the old Active ASA, both ASA are Active. This problem don't solved with the command 'no failover active' on the Standby box. This problem only solved with the command 'no failover' and then 'failover' on the Standby box.

Cisco WAN :: 2921 - Network Design With BGP And Active / Passive ASA's

Mar 1, 2012

The following diagram is showing what I "Plan" on doing or "Hope" I can do. This is the most complicated deployment I have taken on in my profession, and Honestly it is very exciting, but had some questions.
1. The network between the ASA's and Routers, is that suppose to be a Private network or Public Network? I have to assume Public because I want my ASA's to take care of the NAT.
2. ASA's are runing single context Active/Standby so what way will the ASA push out going traffic?
3. The routers need to know about each other in a BGP configuration, correct? We accomplish this using iBGP so will that traffic need to be allowed through my firewall to allow the routers to share that information, or should these routers be talking to each other outside the firewalls?
Is this design possible? I am sure there are limitations as always, just trying to wrap my head around the flow of traffic and where to start.
Additional Details/Requirements -
BGP routers are 2921's that I have control of. Both routers have 4 port GigEtherswitches in them.
ASA's are Active/Passive and cannot be Active/Active due the limitations of the Active/Active Design (VPN limitations)
Both ISP's must be used for outbound traffic, I would like to be able to load balance, but can send some traffic one way and the rest of the traffic the other way based on Routes.
ISP's are not Symentrical, one is 50mbps and the other is 250mbps.
All NAT should take place at the ASA's
Additional Questions:
The routers that have gig etherswitches, can they run HSRP?
Should I be putting Layer 3 switches between the routers and the ASA's instead?
Where should I run my iBGP communication for the routers?

Cisco Firewall :: 5520 - ASA Active / Active Failover And IPS Failure

Mar 30, 2011

I have 2 asa 5520 firewalls including and 1 AIP-SSM-10 module in each of them. the configuration is set using active/active failover and context mode.
Both of them run individualy the IPS module. The IPS is configured using inline mode and fail-open option. However when one of the module fails and the state is changing from up to init or anything else making the IPS to fail then failover is detected and ASA consider it as failover and bounce context to the other unit.
IPS soft is 6.0(4) and ASA soft is 8.0(3)
I have checked cisco doc and it is confusing to me. it says:  "The AIP-SSM does not participate in stateful failover if stateful failover is configured on the ASA failover pair." but it really does participate. Running is not really an option because of production network impact matter..

Cisco Security :: ASA 5520 And Redundant Interfaces Design

Apr 17, 2011

We have two multilayer switches and only one ASA 5520. I'd like to connect ASA in the way described on the picture: each redundant interface includes two physical ones, which are connected to different switches

My question is what kind of link it is necessary to have between switches to make this idea work? I'd have subinterfaces like Re1.100, Re2.200 and so on for my traffic.
I understand that correct design approach is to have two redundant firewalls with failover but we cannot purchase the second one yet.

Cisco Switches :: SG500X-24 Stacking - Keeping Connections Active

May 12, 2013

I am installing a network that has two SG500X-24 switches as core and several SG300-52 switches as access switches. I've seen in the SG500X-24 datasheet that there is a True Stacking feature. But in the data sheet there are not a lot of details about it. My doubt is the following. If I configure the two SG500X-24 switches as a single switch through stacking them, can I connect one SG300-52 switch to these two SG500X-24 switches through two cables (both configured as a LAG in the SG300-52 and in the SG500X-24 stack, one cable per SG500X-24), the  the first cable connected to the first SG500X-24 switch and the second cable connected to the second SG500X-24 switch and keep both connections active?

Nokia-N900 - Multiple Active Network Connections In Windows Xp

Apr 10, 2011

My phone is a Nokia-N900, and I find the most useful way to interact with it from my PC is by ssh. Luckily it is possible to switch out the usb-networking module in the devices kernel to make it appear to windows as a generic RNDIS gadget. Plugging it into a windows PC I can now ssh into it, I can open an sftp session, everything works perfectly...

Except I can't access the web. I can't view other network resources. I look in the network connections section in the control panel and see my two connections, but I don't see any way to set which one to use for what. Seeing as I only use usb0 for ssh and eth0 for everything else, it seems I need a way to set it up so that usb0 only gets port 22 or something similar.

Is there any way to achieve this, or another method by which I could leave my phone connected to my Pc while using it for other network tasks?

Cisco Firewall :: 5520 - Active FTP Does Not Work

Oct 9, 2011

I have an asa 5520 that works fine if you are using passive ftp and ftp inspection is on globally. It is not working for an active ftp session. I tried allowing all ports back to the external ip address of the internal client as a test and this did not work either.
Cisco Adaptive Security Appliance Software Version 8.0(3)
Device Manager Version 6.2(3) 
policy-map Global_Policy

I read another article saying that this command needs to be on the asa "fixup protocol ftp 21"
If this is enabled will it show on the firewall?  How do I enable it?

Cisco VPN :: ASA 5520 - Login DN Account Locked Out In Active Directory

Mar 6, 2011

We are using ASA5520 as our VPN concentrator and has configured IPSec authentication using digital certificates with Microsoft CA for the remote access VPN. The AAA server used for remote user authentication is Windows Active Directory. Screenshot of the AAA configuration is attached. The problem we face is that the "Login DN" account (marked in red box in the screenshot) is frequently getting locked out in the active directory. I have confirmed that the password is the same on both ends and the account is not used any where else.
The NTP server configured for the VPN concentrator is the Active Directory itself but no accounts are configured (not required) for updating the time service in the concentrator.

Cisco Firewall :: Upgrade ASA 5520 In Active / Standby Configured From 7.2(4) To 8.3(1)

Oct 9, 2011

I have been asked to look at upgrading two 5520 ASA configured in a HA pair Active/Standby, from version 7.2(4) to version 8.3(1) to bring it in line with some other ASA firewalls in the organisation.
My question is can I simply upgrade straight from 7.2(4) to 8.3(1) or will I have to step the upgrade from 7.2(4) => 8.2(x) => 8.3(1)
Having read a few articles on the forums and the release notes I think I should be able to go from 7.2(4) => 8.3(1) .
The second part of my query is around the upgrade itself, having researched this a little there seems to be various views on how to go about upgrading a HA pair and I cannot find anything specific on the website.
The approach I am thinking of is simply as follows;

- upload images onto both firewalls in the HA pair
- On the standby from the CLI
clear configure boot
