ASA 5540 FW running version 7.0 (5)

I'm upgrading to PIX new pair of ASA 6.3.5 tonight. I wonder if anyone knows of any pitfalls that I need to know... I also want to know if this version of the code for the ASA are stable. Thanks in advance

We have migrated so a few Pix 520 s v. 6.3.5 to ASAs 7.0.5 running. I recommend their running in parallel and the migration of your servers, and virtual private networks slowly. We did this and it's paid off I crushed the ASAs several times because of software bugs. The sound of ASAs grand to integrate features of the hub VPN, IPS, etc but I'm now firmly to separate these services and their execution on different boxes.

We met EZVPN 831 'NEM' connection problems and it's malforming SCCP IP phones. We took the chance and upgraded to 7.2.1 in the hope that it would resolve due to improved Skinny improvements. Now stateful failover does not work "CSCse81232". So I'll still with another Pandora's box :)

So in summary if you use just the ASAs as a basic firewall 7.0.5 is stable. It's not worth the risk to pass the first major version just because of new features.

P.S. If you use make it sure ASDM you click on apply after each change. Do not a bunch of changes and then hit apply as this will crash 7.0.5. "CSCse22853" this bug was discovered by me and was not specific to just the cmds of DHCP relay.

  • How can I get an ASA 5540 return to the default configuration?

    Is there an easy way to re-apply the default that comes with a new ASA 5540? I would like to have the our ASA 5540 to return to its default to 192.168.1.1 inside the interface and act as a DHCP server, so I connect a PC to start the initial configuration using the ASDM.

    The ASA 5540 is running on asa723 - k8.bin.

  • WRVS4400N ASA 5540 L2L IPSec connection

    I have a remote WRVS4400N with a dynamic outside the address that opens a connection to an ASA 5540 with a static address.

    I'm all set on the side of the ASA.  My questions concern the 4400N.  It does not seem to have a very robust configuration/configuration available for L2L tunnels.  For one my encryption is limited to 3DES.

    But I wonder if I'm missing something in the config.  I have to configure L2L tunnels to two other firewalls.  One firewall has 3 non-contiguous networks, and the other has 2.  I have 5 tunnels configuration, this is the only way?  What I'd like to see is 2 tunnels, one for each firewall distance, but then each tunnel would have access to networks (like on the side of the ASA), is anyway to do this?  Perhaps a useful command line for this unit?

    My other question concerns the tunnel-groups I've implemented on my ASA, and I do not want to use the proper names... However I can't seem to find a way to allow this to happen on the side of 4400N... I mean, I need a way to create a 'keyword' identifier or a "firewall identifier" on the 4400N and I do not see an appropriate field in the web interface.  Someone at - it ideas?

    Thanks in advance.

    Hi WS, the WRVS router does not support a complete tunnel configuration or routes to have a multi site configuration. You would need a separate tunnel for each location.

    Traditionally, the WRVS router was not a good game on any platform ASA. In most cases, I saw when a tunnel has put in place will be the router WRVS crash in an hour or less due to low memory. If you run a scenario where the WRVS stops responding or the tunnel down, this is the likely scenario.

    I highly recommend is not to use the WRVS router for all tunnel with the ASA. If you are looking to stay in the field of small business, a RV220W or a RV042 router would be a much more suitable match.

  • ASA - 5540 used for IPSec VPN only - I can do away with Nat 0?

    I'll use an ASA 5540 as our head of VPN endpoint only - and not as a firewall.

    Also, we have a class for our company internal address space routable B address, so we don't need NAT. I would like to disable the function NAT 0 if I can so I always add NAT 0 to ensure that the 5540 does not NAT.

    Y at - it an easy way to disable the need using NAT 0?

    Are there any of the draw to do that?

    You can disable the use of nat 0 disabling the nat control.

    To achieve this, go to the global configuration mode and use this command:

    no nat control

    To check whether you have it turned on, you can check it with:

    SH run nat-control

  • Problems running version 29

    We had problems to install and run Version 29 on various PC platforms (portable and desktop computers) all running 64-bit Windows 7 SP2. The product appears to install correctly, but then simply of does. We had to go back to the Version 28, and that sometimes takes a lot of tweaking to get this working as well (i.e., first duty \Mozilla directory Program Files (86) and then reinstall).

    In addition to this difficulty, myself and other users are not too crazy about the new look. In particular, the absence of the Mozilla little 'globe' in the upper-left hand corner of the screen that allows a double click Close Program. This is where many users are accustomed to the closure of a Windows program, and that the habit is hard to break. I looked for alternatives and programs that make the Version 29 more like previous versions, but have not seen this addressed peculiarity. So I stick to 28 V until she returns.

  • NAT-control over ASA 5540 v8.3.2?

    Is there an equivalent command in 8.3.2 disable NAT; That is to say. no control NAT?

    I think it was in v7.2 but can't find in in 8.3.2.   I use this stricktly 5540 for a VPN IPSec lan lan 2 head of tunnel and do not NAT at all. If I disable NAT, I won't have to deal with the obnoxious ACL nat_0 which grows and grows and grows. Is this possible in 8.3.2?

    Hello

    The control of nat command has been removed in version 8.3

    The command to control NAT is discouraged. In order to maintain the requirement that all traffic from a security interface than a security interface lower translate, a NAT rule will be inserted at the end of article 2 for each interface ban all remaining traffic. Nat-control command was used for NAT configurations defined with older versions of the Adaptive security appliance. The best practice is to use access rules to control access rather than rely on the absence of a NAT rule to prevent traffic through the Adaptive security device.

  • Firefox continues to ask to update, I am running version 26?

    I downloaded Firefox Setup Stub 26.0 and installed three times, each time that it restarts, I see a message saying: there is a newer version of Firefox, when I click the link it asks me to download the same file again? I'm running with windows vista with Firefox as my default browser, I hope you can help because it becomes quite annoying with the constant popup telling me to update, thank you, John.

    Where my reference was confusing, here's a direct link to the article with the measures to clear false information about your version of Firefox: websites say that Firefox is obsolete or incompatible, even if it's the latest version.

  • If the latest version of Firefox is 17, why get invited to day 14.0.1 when I am running version 12?

    I am running Windows 7 64-bit OS, and I currently version 12 of Firefox are installed (updated in May). I am building a browser vs. OS compatibility matrix, so I did a little 'Googling' today to see what Firefox versions are currently supported. When I opened Firefox to see if I was running the latest version, I got a prompt to upgrade to 14.0.1, yet the latest version is 17. This causes me some confusion. In addition, some sites offer Firefox 64-bit is not supported in WIndows and others say that it is in the Act supported. Could someone please confirm or deny this?

    How many times have you run Firefox in the last 4 months? Remember that any postponement of this update? If this update has been previously downloaded, but never installed, maybe the installer wants to finish this work before check you for a newer version.

    Mozilla does not have a 64-bit version of Firefox for Windows release. The 32-bit version works well on the 32-bit and 64-bit Windows versions.

    There is a version of 64-bit third-party named Waterfox you could look in, but I suspect that any gain in the ability to use memory would be offset by reduced with modules compatibility...
