Lost Configuration on Power Outage

beatinger
Level 1
Level 1

Yesterday, a very strange incident occurred, which led to the partial loss of my ASA5540 configuration.  The building in which our servers are housed, suffered a power outage of some type, and when the power came back on, and the ASA5540 rebooted, it kept trying to load an older binary, asa803-k8.bin, in a continuous loop.  I drove out there to inspect what was happening, and found that the BOOT variable was setup to "try" the older version first, then the newer version (asa917-32-k8.bin).  Unfortunately, it would never try the new version, and instead would just keep failing on the older version.  Not sure how all of this came to be, but I couldn't resolve getting out of the loop until I pressed <ESC> to break out of it, and into the ROMMON.  Then, at the ROMMON, I typed "boot help", and it then loaded an even older version of the IOS, asa722-k8.bin.  When that happened, the existing configuration changed dramatically, and I lost most of my configuration.  I figured out how to change the BOOT variable so that only the newest IOS would load, but my configuration is still mostly gone.  I have cut and paste it here, to try to see if I can get some help as to why when this is loaded, I cannot gain access to the Internet.  I can ping outside, but none of my servers on the inside can gain internet access.  I believe it must have something to do with NAT.  I also lost most of my ACL list that I had built up for access into the servers.  Here is the configuration file, as it now exists, with some of the IPs masked for privacy:

Unfortunately, I do not know how to view the contents of that file.  I do have access to the firewall via ADSM.

To get the servers back up and running, I put our old Cisco PIX 515E back in, and we are up for now, but need to get back up on our ASA5540 as soon as possible.  I have a separate question regarding blocking a specific network subnet on the PIX 515E.  I have put the following in the old conduit list, but it is placed at the BOTTOM of all of the permits, so it doesn't work:

 

conduit permit tcp host 12.xx.xx.88 eq 3389 any
conduit permit tcp host 12.xx.xx.88 eq ssh any
conduit permit tcp host 12.xx.xx.88 eq ftp any
conduit deny tcp host 212.70.149.82 any
conduit deny tcp host 212.70.149.51 any conduit deny tcp any any
conduit deny udp any any

 

I know that the config needs to look like this, but I don't know how to get the lines up to the top:

 

conduit deny tcp host 212.70.149.82 any
conduit deny tcp host 212.70.149.51 any conduit deny tcp any any

conduit permit tcp host 12.xx.xx.88 eq 3389 any
conduit permit tcp host 12.xx.xx.88 eq ssh any
conduit permit tcp host 12.xx.xx.88 eq ftp any
conduit deny udp any any

 

Thank you all very much for your help!  It is most appreciated.

Here are the objects I am refering to.  You only have two objects that have host IPs configured.  I am assuming that the others should not be empty and that they should be in use?

object network VM-HyperV-Port4
host 10.1.252.190
description Created during name migration
object network WebServerIIS10_1

host 10.1.252.250
description Created during name migration
object-group network IIS85Server
object-group network WebServerIIS80
object-group network WebServerIIS10
object-group network Sendmail
object-group network DNS-Server
object-group network DRAC-VirtualServer
object-group network SQLServer
object-group network ExchangeServer
object-group network NAS

 

Could you provide us with the IPs for these servers and then we can get started on the NAT and ACL configuration.  

here is an example of how to configure your NAT.

object network webserver
 host 10.1.1.10

 

nat (DMZ,outside) source static interface service tcp http

 

object network server_subnet

 subnet 10.1.1.0 255.255.255.0

 nat (DMZ,outside) dynamic interface

 

access-list outside-in extended permit tcp any host 10.1.1.10 eq 80

access-group outside-in in interface outside

 

There are several reasons that the ASA would try an older version...1. the existing version might have become corrupt. 2. The existing version, for whatever reason, may have been removed from the flash.  3. The configuration specified the older ASA version as 1st in the boot sequence to try.

oh dear hell of a wild ride for you. you must consider open a TAC case with cisco. It should not revert back to old setup. I can completely understand your pain as network engineer. curious what cause the firewall to back into old day. seem like to it gone back to the past instead of back to the future. anyways jokes aside.

 

I never worked on Cisco PIX 515E cant assist on this but how much you have build the 5540. I noted there is no NAT commands if you need assistance to build the new unit happy to help you.

 

 

please do not forget to rate.

Hello Sheraz,
Thank you very much for your reply. Yes, this is one the strangest encounters I've been through. Why Cisco would design their software to not only try to load an OLDER IOS with no warning, and then wipe out an existing configuration, really baffles me. I am a software engineer myself (more so than a network engineer), so if I were them, I would build in plenty of "ARE YOU SURE?" prompts, etc., and at least offer a save of the existing configuration, and so on. This is truly a wild ride, and a very expensive one.
And yes, you are absolutely correct that all of the NAT configuration is missing. Here is what I get when I type "show nat:"
ciscoasa5540(config)# show nat
ciscoasa5540(config)#
Nothing at all...lol. Wow.

Unfortunately, I am not familiar enough with the new IOS to get all of my NAT instructions back in. Please let me know how I should proceed.
Most appreciated!

I can feel for you. Please let me know what is your network design happy to get spare time and help you to get this nat up and running again.

 

could you share the old firewall config change the IP addresses for security reasons I shall get them convert for you for your new unit ASA.

please do not forget to rate.

Hello Sheraz,
Okay, I have worked on the configuration today, and did my best to add the NAT commands back in.
I am now getting the following when I issue the "show nat" command:
ciscoasa5540(config)# show nat

There is more, but I believe this is the pertinent stuff.

 

And the show nat now shows the following:

translate_hits = 0, untranslate_hits = 0

Manual NAT Policies (Section 3)

translate_hits = 0, untranslate_hits = 0

 

Does this look correct now?

 

Also, how do I go about with the rating process?  Sorry that I am still quite the beginner with all this!

Do you not have a backup of the configuration you had on the ASA?  If not then I suggest that once this is up and running again, get a daily or weekly backup service up and running.

In addition to missing NAT statements, almost all the objects you currently have configured are empty.  Start by filling in those values and once they are populated get NAT in place.  Once those two are done work on getting the ACLs restored.

 

Have you checked the startup config to make sure that your old configuration is there?

For furture referece, If you face a similar issue you can select which image to boot from that is stored in flash from ROMMON by using the command boot <file path>  replace file path with the location where the file is (for example boot disk0:asa-file-image.bin)

Optionally you can try to boot from a TFTP server.  And as a last effort you can try to edit the confreg so that the ASA will ignor the configuration upon boot.  Change the confreg value to 0x41.  When done change it back to 0x1.

Hello Marius,

 

Thank you for your reply.  Unfortunately, I do not have the configuration backed up, which is really surprising, which is one of the very first things that I do upon completion of a setup.

 

I read your reply, and I dont' fully understand what this means: "In addition to missing NAT statements, almost all the objects you currently have configured are empty. Start by filling in those values and once they are populated get NAT in place. Once those two are done work on getting the ACLs restored."

 

I am not sure where to start, as once I had gotten this configured, I went on to doing a huge programming project, and I am totally lost at this point.  Unfortunately, I am getting old, and having a lot of sleeping issues, so my memory just isn't what it used to be.  I am not sure where to start, or what to do at this point.  Thank you very much for your help.

Here are the objects I am refering to.  You only have two objects that have host IPs configured.  I am assuming that the others should not be empty and that they should be in use?

object network VM-HyperV-Port4
host 10.1.252.190
description Created during name migration
object network WebServerIIS10_1

host 10.1.252.250
description Created during name migration
object-group network IIS85Server
object-group network WebServerIIS80
object-group network WebServerIIS10
object-group network Sendmail
object-group network DNS-Server
object-group network DRAC-VirtualServer
object-group network SQLServer
object-group network ExchangeServer
object-group network NAS

 

Could you provide us with the IPs for these servers and then we can get started on the NAT and ACL configuration.  

here is an example of how to configure your NAT.

object network webserver
 host 10.1.1.10

 

nat (DMZ,outside) source static interface service tcp http

 

object network server_subnet

 subnet 10.1.1.0 255.255.255.0

 nat (DMZ,outside) dynamic interface

 

access-list outside-in extended permit tcp any host 10.1.1.10 eq 80

access-group outside-in in interface outside

 

There are several reasons that the ASA would try an older version...1. the existing version might have become corrupt. 2. The existing version, for whatever reason, may have been removed from the flash.  3. The configuration specified the older ASA version as 1st in the boot sequence to try.

Hello Marius,
Thank you very much for helping me out with this. To further complicate things, I am suffering from insomnia and withdrawals from Lunesta, which destroys your memory and cognitive abilities. Doctor didn't inform me of this really bad side-effect. So, I'll be going back out to the server room tomorrow, and will get up tomorrow morning and start trying to piece this back together again. Again, I really appreciate your input, very much.

Hello,

 

Based upon the information that both of you kind gentlemen pointed out, I was able to get this firewall working again.  I had some difficulty with the ACLs, and had to change them to using the network objects rather than specifying a host. As in the following example:

 

access-list outside_access_in extended permit tcp any4 object WebServerIIS80 eq https

 

I also had to add this NAT instruction:

 

nat (inside,outside) after-auto source dynamic any interface

 

And now everything is finally working again.  Thank you very much for your assistance!

I am going to post a new question about getting VPN going, as that is the next item on my list to work on.

 

Thank you again!

Hello there,

I was wondering why I stopped hearing from both of you with regards to this case.  I want to make sure that I am doing the right thing when it comes to giving you the proper credit for helping.  Can you please let me know how I go about doing that, or if I didn’t do that, or if I did something wrong or something?  Thank you very much!

The answer or answers you feel is the correct answer, you can mark as a correct answer. Other posts you found helpful you can assign points to.

When it comes to reporting a bug to Cisco, you need to open a TAC case as they need to see the issue for them selves as well as collect data to analyze.

Oh, and I would like to add that indeed, the Cisco IOS has a lot of bugs, that I should be reporting to them somehow.  I just don't know how.  I found several more while going through this nightmare.  Really stupid stuff like the IOS thinking that "10.1.252" and "10.10.1" are the SAME SUBNET.  Wow, that one had me laughing.  I had to revert to using "172.16.1." on an interface instead, just to get around this.  Please let me know how to report to Cisco, and I'll do that.  Thank you again!
