Cisco Firewall :: ASA 5515X - Config Loss After Primary Firewall Reloaded

Sep 23, 2012

I have a strange issue which happened to me last weekend with two ASA 5515X on version 8.6(1)2. There was a planned power shutdown which only affected the primary firewall. Failover was configured and running successfully. The configuration was also saved after every change made. After power was shut and primary firewall went off the secondary took over like it should but unfortunately all configuration was gone. We immediately powered on the primary again but also this one lost the configuration.
While reconfiguring the firewall we ran into another problem. The devices won't pair although it was the correct configuration. After three times removing and adding the same failover configuration the devices accepted the failover and worked together again.
I went through the bug toolkit and white papers regarding ASA 5515x and this particular version but were not able to find anything.

Cisco Firewall :: 5515x Apply On Firewall / Switches To Make Implementation Successful

Apr 22, 2013

I will be implementing a new firewall (cisco asa 5515x) on my existing  3750x (server switches) and my 2960s (user switches). What should I need to apply on my firewall and swtiches to make the  implementation successfull.  I will put my 3750x as my DMZ and my 2960s  as my inside.  The 3750x have multiple subnet and also the 2960s.which  features and technologies i need to know on those 3 products.  my 3750x  and 2960s don't have any ACL defined and most common features are vlan,  switchport, trunking, spanning-tree, stacking,  my asa knows that my 3750x/2960s have multiple vlans.  my current  connection right now on 3750x and 2960s is just through 6 ports i  assigned as one trunk, below is my config [code]

my  2960s vlans are almost the same with my 3750x except vlan 160, 170,  192.  but of course when i put this in asa, i have to segragate vlan for  3750x (192, 100, 110,160, 170) and 2960s (130, 150).  for my 2960s  connection to the asa and since this will have big bandwidth, i will use  3 ports on my asa (and trunk it) connecting to my 2960s and i will use 2  ports on my asa (and trunk it) connecting to my 3750x.  the one  internet ports and my one management ports on my asa will stay like  that.

Cisco Firewall :: Upgrade From 8.2 To 8.6 For New ASA 5515X

Sep 19, 2012

My customer has a rather complex configuration on an ASA 5510 running version 8.2.

They are migrating to new ASA 5515X models which of course only version support 8.6
How can i convert the configuration from 8.2 to 8.6 since the new ASA's do not support the earlier versions?
The X series seems to be a great option for new deployments but what about replacements of existing older models?

Cisco Firewall :: ASA 5515X 8.6 IOS For NAT Control

Feb 21, 2013

I am in a process of replacing the Cisco ASA 5510 with 7.3 OS with a new Cisco ASA 5515X with 8.6OS. In the existing Cisco ASA 5510, we have configured 'no nat-control' for which the traffic from all sub-interfaces were flowing to the lower security interfaces without any NAT command. Just access-lists were configured. Now how do i acheive the same in the Cisco ASA 5515X with 8.6? I do not find any 'no nat-control' command available for it.

Jun 4, 2013

What is the maximum number of contexts a pair of 5515Xs in HA mode can support?
I know each 5515X can have a max of 5 contexts, but does that mean in HA mode a pair can support 10 with license pooling?

Cisco Firewall :: Remote Desktop Connection To ASA 5515x

Feb 5, 2013

I have ASA 5515x and it has already Internet Connection since my firewall is not "production". So right now I'm trying to configure a Remote Session just for a test and eventually I was not able to connect from it. I followed the instructions from technotes but still Remote Connection dropped. Here's my sample configuration on my firewall, btw I also configured a service policy rule and ACL just to make sure if I can able to access the Server inside my network but Session also dropped. 
nat (inside,outside) source static
access-list 110 extended permit tcp host host eq 3389

Cisco Firewall :: Management Interface In Cluster ASA 5515x?

Jan 6, 2013

I have a misanderstand about management interface configuration in cluster. So I have a cluster asa 5515X with management interface. i Would like to be able to connect to any of the member of my cluster on management interface, so i would like to fix a different ip on management interface on each of my node ip 92 and 91. I think it is the only way to make asa firmware update to access local flash on each node.

Cisco Firewall :: Maximum Number Of 1-1 Static Nat Entries On ASA 5515X Or 5525X?

Aug 7, 2012

I have a FWSM cluster that I exceeded the maximum number of static nat entries on.  i migrated the connectivity off to a pair of PIX 535's that seem to be handling the adderess translation needs.  however the number of NAT entries being required is increasing and being the PIX series wal EOL'd several years back..I need to replace them..  The static 1-1 nat entries cannot be summarized into network as the hosts that are being nat'd are scattered all over various micro subnets in the all 3 rfc1918 ipv4 address ranges and they are being manged directly by snmp and SNMP-trap and other services that prohibit the use of many-to-one nat.   Is there a mknown maximum number of static 1-1 nat entries that can be defined on the ASA 5515-x, 5525=x and higher ASA firewalls?  Say I wanted to be able to grow to 2500 or more static 1-1 nat entries.  I am currently running 2010 1-1 static host nats currently.

Cisco Firewall :: ASA5540 - EAL4 Transparent Firewall Config

Mar 14, 2011

I am configuring an ASA5540 firewall for a client, only difference to usual being that it is to run in Transparent mode. I have looked through for an EAL4 transparent firewall config guide but found nothing and therefore assumed that the usual one would be used.The clients security bod has now come back and insisted MAC filtering should be used but I can find no reference of this anywhere. Does MAC filtering is required to make a transparent box EAL4 compliant and if so where I can find documentation supporting this?

Cisco Firewall :: ASA 7206 Failover When Primary ISP Goes Down

Apr 4, 2012

I have an outside 7206 router that is configured with BGP. Behind that I have an ASA 5520 with a failover. Everytime my primary ISP goes down I have to failover the ASA to restablish a connection to the secondary ISP. When the primary comes back on line I have to fail it over again. I have had Cisco TAC look at the ASA and they didn't see anything misconfigured on the ASA. Doesn't seem to be any problems with the router config either.

Cisco Firewall :: ASA 8.2 Getting ACLs Loss

Jan 23, 2013

I'm almost afraid to post since my stuff is so OLD! I have a 350 Series PCI Wireless LAN Adapter in my old WinXP, not wireless-ready Compaq.I live off the grid, no landlines and have been using a Franklin CDU680 USB air card to connect to the Internet. The air card doesn't like my Compaq - occasionally crashes it. I thought to put the air card in a router to solve the problem and communicate with the router using the Cisco 350. Bought a Cradle Point router from my ISP and plugged in the Franklin.  Then spent the next 5 days trying to get the Cisco 350 to associate with the router.I now have a profile with the router's SSID in it that according to the ACU's status report is associated with that SSID. Problem is that there is no Internet connection.

Cisco :: ASA5510 - Event Primary Firewall Fails

Jun 6, 2011

The client is only interested to have one-WAN(MPLS) and One internet circuit with Dual ASA5510 primary/failover configuration. In the event primary firewall fails, there is no direct WAN/internet connection to failover firewall. I beleived that  to mitigate the issue,  I needed to add a layer 3 switch , and have each circuit (MPLS/Internet) or (modems/routers) connect to a L3 switch. L3 switch will do the vlan based routing based on the state of firewall. ? am i correct?  The client want automatic failover to secondary firewall in the event the actual firewall failed without impacting the day to day business.

Cisco Firewall :: NAT Config Changes From 6.2 To 8.4?

Sep 14, 2011

I am converting one PIX config (in 6.2) format to 8.4 format manually.I am stuck at the following statements.
global (outside) 1 netmask
global (outside) 1 netmask
nat (inside) 0 access-list 101
nat (inside) 1 0 0
access-list 101 permit ip host
My understanding from the old config file was that any traffic coming from source  to destination would NOT be translated and this shall remain the same in 8.4.How can I rewrote the NAT commands?

Cisco Firewall :: ASA 5505 Loss On Configuring Twice NAT

Mar 30, 2012

There seems to be a large number of the subject queries in one form or another.  Having acquired an asa 5505 and using 8.43 firmware and the ADSM gui for router configuration it has not been an easy transition from other products.   I have come to understand embedded NAT objects for basic port forwarding but am at a loss on configuring twice nat or manual nat, not really ever dealing with it before, or in this manner.  
What I would like to suggest to the experts, is to include far more ADSM web gui examples and discussion for manual nat.   The tools are all there - in the nat rules editing page,  the display of the rules pictorially and the packet flow at the bottom of the page (and finally thru packet tracing).   What is needed is more on the actual entries on the nat editing pages and the logic and explanation of those entries.   In this forum what I would like to see is when there are responses that they include both the CLI recommended entries b AND the associated adsm web gui pics.  With good documents for reading and examples in the forum, I think there should be much less confusion allowing more attention to some very complex scenarios. At the very least I and others like me will get better edumecated.  I am looking to understand CIsco packet routing through explanations of the web gui entries. In fact, I am learning far more by trying to understand the web gui vice simply copying and entering CLI commands.  In terms of documents, for example, there should be a very thorough explanation of the relationship between "Translated Addr:" in the first NAT editing page with "Destination Inteface" in the second Advanced page .I have added the packet tracing jpegs for further context.  There is an UNNAT lookup entry (first trace block, out of view on the pic) a concept which is missing in the documentation I've read that needs to be added but it is illuminating in how the router handles traffic.   What is also interesting is the fourth jpeg which also shows the flow designation of a packet and its handling internally (new packet or one that is associated with an existing packet (previously identified and put in an appropriate table xlate etc)).

Cisco Firewall :: 5505s - Secondary ASA Active And Primary Is On Standby

Dec 5, 2011

We have 2 ASA 5505s in a data center at a remote site.
Whilst troubleshooting another issue I noticed the below. I don't know much about fail over but this would suggest that the secondary ASA is active and the primary ASA is on standby.
if the primary is "active" then how come the secondary is the active ASA? I would have thought that once the primary ASA became active this would assume the "main" role".

Cisco Firewall :: Replacement Of Primary Unit Failed ASA5510

Sep 7, 2011

I have an issue bringing up my RMA'd primary ASA unit.
So what happened so far:
1. primary unit failed
2. secondary took over and is now secondary - active (as per sh fail)
2. requested RMA at Cisco
3. got ASA and checked that Lic (SSL), OS (8.2.2) and ASDM are at the same level as the secondary
4. issued wr erase and reloaded
5. copied the following commands to the new (RMA) primary unit:
failover lan unit primary
failover lan interface Failover Ethernet3
failover interface ip Failover 172.x.x.9 standby 172.x.x.10
int eth3
no shut
wr mem
6. installed primary unit into rack
7. plugged-in all cables (network, failover, console and power)
8. fired up the primary unit
9. expected that the unit shows:
Detected an Active mate
Beginning configuration replication from mate.
End configuration replication from mate.
10. but nothing happened on primary unit
What is a valid and viable approach in replacing a failed primary unit? Is there a missing step that hinders me to successfully replicate the secondary - active config to the primary - standby unit.
I was not able to find anything related to ASA55xx primary unit replacement with a clear guideline or step by step instructions.

Cisco Firewall :: FWSM On 6500 TCP Connection After Crash On Primary Network

Aug 6, 2012

We are running an FWSM on a 6509 with a SUP720. Firmware 3.2(18), in MultiContext Routed Mode, with shared MSFC.Everything runs fine on this baby most of them time, however occasionally without warning and with no specific pattern the Primary node will fail (as in completely stop responding) and the secondary will takover as active. Two get the primary up agian, I reset the hw-module and then no failover active on the secondary to return the primary as active. However, after this event, I start to experience strange issues with connectivity. Certain TCP src dst combinations will just not work.

Cisco Firewall :: Primary ASA 5510 Turns To Standby When Both Units Power Up

Mar 22, 2011

I have three pairs of ASA5510 firewalls, each pair configured as a failover pair. When each pair boots up, even if I boot up the primary first, when they are both up and the primary/active syncs to the secondary/standby, the primary always switches to standby and the secondary thus becomes active.
What would cause this?  It happens on all three pairs. Does failover look for the highest ID or IP address to determine which of the pair will be active?

Cisco Firewall :: Adding Failover ASA 5510 Back After Configuration Changes On Primary

Nov 28, 2012

I had a working active/passive pair of ASA5510's, and then I had to do a rush firmware upgrade, but didn't have time to do it on the secondary at the same time.  Now I have made config changes and upgraded the secondary firmware to be the same, and wish to know if I plug it back in if it will think the secondary has the "correct" config or if it will know that the primary is newer.  I disconnected the failover cable because it was complaining about version mismatches constantly.
Is it safe to add the secondary back in or is it possible it will be declared newer and overwrite the config?
