  Hello

  I think you've got your STATIC reversed lines, they must be:

  static (BCM, external) client_routable_address tcp 6881 192.168.20.10 6881 netmask 255.255.255.255

  Assuming that 'client_routable_address' is your public IP and the BMC is your 'inside' or the 'DMZ' interface

• Requirement of DNS and DHCP Server Essentials 2012 home

  I have a Server Windows Essentials 2012 acting as DNS and DHCP server with a domain name for backups etc on my home network. It's that everything works fine, no errors, no problem. Works well actually, telling me when the children did not install updates or restarted.

  I have two groups of users. My sons step, 10 and 12, which I want to use OpenDNS as a provider external DNS with a policy very, very limited and my wife and me who want to use indications of root or Google DNS or any other DNS provider. Others, specific devices no user (box of the xBox, WII, Satellite, TV, CCTV etc.) can use.

  Before the 2012 server, I had a 2 k 3 server running in a virtual machine for DHCP, alone and put my wife and my devices on static reservations with the just and external DNS provider used OpenDNS as the default scope, DNS. Unfortunately different bits of domain services 2012 don't seem to work unless the server of 2012 is the first DNS server listed on client machines (backups failed. Impossible to find other local computers). Currently, this means that we are all using OpenDNS.

  What I would like is a way to say 2012 to send adult group DNS queries to another DNS provider and leave the rest at default to OpenDNS, while still having them register in the original DNS domain. Any suggestions?

• Configuration of static translation "inverted".

  I am trying to configure a PIX with static translation "inverted".

  If I understand correctly, with conventional static translation if I want my host (10.10.10.10) inside to be 'visible' on the external interface like 192.168.5.5), would be my config: -.

  public static 192.168.5.5 (Interior, exterior) 10.10.10.10 netmask 255.255.255.255

  However, I have an external host (203.203.203.203) I want to be 'visible' inside interface as 10.10.11.11. I would have thought the config would be: -.

  public static 10.10.11.11 (exterior, Interior) 203.203.203.203...

  but it does not work. Is this possible and if so, how?

  Thanks to advnance.

• Static translation PIX

  Just a quick question I have if I'd put on the table. I have a Pix 515, with a total of four DMZ. I had to configure static mappings in the DMZ for some servers. Here's my question. There are three types of static translations:

  High and low note see security levels.

  1. static (high, low) high low

  2. static (high, low) high high

  3. ????

  What is the third static confgiuration and that it would be used for.

  Thanks in advance

• Maximum static translations

  Hi all

  I have a 520 PIX with 16 MB of flash and 128 MB of ram. No one knows what the maximum number of static translations, you can have in the configuration. I would like to translate staticly class B around just for outgoing traffic.

  Thank you

  Steve

  Hello

  The amount of static translation depends on the size of the RAM that you encounter. each translation to 128 bytes of memeory... maybe it is useful for your

• Static translation with Port forwarding

  Hello

  I have a scenario in which two public ip address (the one with HTTP requests & other with query SMTP/SSL for OWA) must be translated on a single inside the ip of the ISA Server in the DMZ. Please suggest which is the best practice. I know that we cannot do a NAT because the two addresses ip cannot translate into one. Use the static translation with forwarding Port of best practice to access the ISA server for OWA? What is the best security that can be applied at the moment? I'm going to redirect only requests to port 80,8080,25,443,110. I'll also create access list to only allow as these ports.

  I need to recommend this to a client. Please advice.

  Thank you

  Kevin

  Port forwarding is the best way to go here. As you already know, you can enter a static for two outside IP pointing to an inside (or vice versa), but statically mapping ports just will be fine. Similarly, simply allow these ports in your incoming ACL and you'll be good to go.

  You want something like the following:

  static (inside, outside) tcp XXX1 80 a.a.a.1 80

  static (inside, outside) XXX1 8080 a.a.a.1 8080 tcp

  static (inside, outside) tcp x.x.x.2 25 a.a.a.1 25

  static (inside, outside) tcp x.x.x.2 110 a.a.a.1 110

  public static x.x.x.2 a.a.a.1 443 tcp (indoor, outdoor) 443

  list of allowed inbound tcp access any host XXX1 eq 80

  list of allowed inbound tcp access any host XXX1 eq 8080

  list of allowed inbound tcp access any eq 25 x.x.x.2 host

  list of allowed inbound tcp access any host x.x.x.2 eq 110

  list of allowed inbound tcp access any host x.x.x.2 eq 443

  Access-group interface incoming outside

  where x.x.x. [1 | 2] is your public IP address and a.a.a.1 your home server.

  You may have installed one or more variants of the malware "VSearch' ad-injection. Please back up all data, and then take the steps below to disable it.

  Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. It is never necessary for her, and relying on it for protection makes you more vulnerable to attacks, not less.

  Malware is constantly evolving to work around defenses against it. This procedure works now, I know. It will not work in the future. Anyone finding this comment a couple of days or more after it was published should look for a more recent discussion, or start a new one.

  Step 1

  VSearch malware tries to hide by varying names of the files it installs. It regenerates itself also if you try to remove it when it is run. To remove it, you must first start in safe mode temporarily disable the malware.

  Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for other instructions.

  Step 2

  When running in safe mode, load the web page and then triple - click on the line below to select. Copy the text to the Clipboard by pressing Control-C key combination:

  /Library/LaunchDaemons

  In the Finder, select

  Go ▹ go to the folder...

  from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

  A folder named "LaunchDaemons" can open. If this is the case, press the combination of keys command-2 to select the display of the list, if it is not already selected.

  There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. Please don't skip this step. Files that belong to an instance of VSearch will have the same date of change for a few minutes, then they will be grouped together when you sort the folder this way, which makes them easy to identify.

  Step 3

  In the LaunchDaemons folder, there may be one or more files with the name of this form:

  com Apple.something.plist

  When something is a random string, without the letters, different in each case.

  Note that the name consists of four words separated by dots. Typical examples are:

  com Apple.builins.plist

  com Apple.cereng.plist

  com Apple.nysgar.plist

  There may be one or more items with a name of the form:

  com.something.plist

  Yet once something is a random string, without meaning - not necessarily the same as that which appears in one of the other file names.

  These names consist of three words separated by dots. Typical examples are:

  com.semifasciaUpd.plist

  com.ubuiling.plist

  Sometimes there are items (usually not more than one) with the name of this form:

  com.something .net - preferences.plist

  This name consists of four words (the third hyphen) separated by periods. Typical example:

  com.jangly .net - preferences.plist

  Drag all items in the basket. You may be prompted for administrator login password.

  Restart the computer and empty the trash.

  Examples of legitimate files located in the same folder:

  com.apple.FinalCutServer.fcsvr_ldsd.plist

  com Apple.Installer.osmessagetracing.plist

  com Apple.Qmaster.qmasterd.plist

  com Apple.aelwriter.plist

  com Apple.SERVERD.plist

  com Tether.plist

  The first three are clearly not VSearch files because the names do not match the above models. The last three are not easy to distinguish by the name alone, but the modification date will be earlier than the date at which VSearch has been installed, perhaps several years. None of these files will be present in most installations of Mac OS X.

  Do not delete the folder 'LaunchDaemons' or anything else inside, unless you know you have another type of unwanted software and more VSearch. The file is a normal part of Mac OS X. The "demon" refers to a program that starts automatically. This is not inherently bad, but the mechanism is sometimes exploited by hackers for malicious software.

  If you are not sure whether a file is part of the malware, order the contents of the folder by date modified I wrote in step 2, no name. Malicious files will be grouped together. There could be more than one such group, if you attacked more than once. A file dated far in the past is not part of the malware. A folder in date dated Middle an obviously malicious cluster is almost certainly too malicious.

  If the files come back after you remove the, they are replaced by others with similar names, then either you didn't start in safe mode or you do not have all the. Return to step 1 and try again.

  Step 4

  Reset the home page in each of your browsers, if it has been modified. In Safari, first load the desired home page, then select

  ▹ Safari preferences... ▹ General

  and click on

  Set on the current Page

  If you use Firefox or Chrome web browser, remove the extensions or add-ons that you don't know that you need. When in doubt, remove all of them.

  The malware is now permanently inactivated, as long as you reinstall it never. A few small files will be left behind, but they have no effect, and trying to find all them is more trouble that it's worth.

  Step 5

  The malware lets the web proxy discovery in the network settings. If you know that the setting was already enabled for a reason, skip this step. Otherwise, you should undo the change.

  Open the network pane in system preferences. If there is a padlock icon in the lower left corner of the window, click it and authenticate to unlock the settings. Click the Advanced button, and then select Proxies in the sheet that drops down. Uncheck that Auto Discovery Proxy if it is checked. Click OK, and then apply.

  Step 6

  This step is optional. Open the users and groups in the system preferences and click on the lock icon to unlock the settings. In the list of users, there may be some with random names that have been added by the malware. You can remove these users. If you are not sure whether a user is legitimate, do not delete it.

• Laptops acquire wrong address DHCP, DNS and gateway wireless

  I have problems with two laptops. For some strange both acquire the bad DHCP, DNS and gateway (server) respond when I try to access the Internet via Wi - Fi. For some reason, this does not happen when I use the LAN (cable) connection.

  that is instead to fetch the address: 133.24.56.78 (no real address), the system retrieves / uses 111.22.33.44 (again, not a real address). BTW, these two systems are configured to fetch automatically get IP addresses and DHCP. I tried to fix the connection in both cases, but it did not work.

  What can I do to fix this?

• IPSec Tunnel between Cisco 2801 and Netscren 50 with NAT and static

  Hello

  My problem isn't really the IPSec connection between two devices (it is already done...) But my problem is that I have a mail server on the site of Cisco, who have a static NAT from inside to outside. Due to the static NAT, I do not see the server in the VPN tunnel. I found a document that almost describes the problem:

  "Configuration of a router IPSEC Tunnel private-to-private network with NAT and static" (Document ID 14144)

  NAT takes place before the encryption verification!

  In this document, the solution is 'routing policy' using the loopback interface. But, how can I handle this with the Netscreen firewall. Someone has an idea?

  Thanks for any help

  Best regards

  Heiko

  Hello

  Try to change your static NAT with static NAT based policy.

  That is to say the static NAT should not be applicable for VPN traffic

• ASA 5500 and static NAT 1-to-1

  We currently have a pair of s ASA 5500 failover providing firewall & nat with inside, outside and the dmz interfaces. We do PAT interface for most of the internal to the external and static connections 1-to-1 NAT for specific hosts that need to accept connections from the outside inside. The space of the static nat is a 27 which includes the address of the external interface. It's that everything is working properly.

  However, we are out of space for the static NAT to this/27. I would like to be able to add a different network, probably another 27, for the more static NAT but I'm a hard time to find the best way to do it. Is this possible with a network that does not include the external interface on the ASA?

  Here are some of our current NAT config:

  Global interface 10 (external)

  NAT (inside) 10 0.0.0.0 0.0.0.0

  (dmz1, outside) static dmz1-net-net dmz1 netmask 255.255.255.224

  static (inside, dmz1) 192.168.0.0 192.168.0.0 netmask 255.255.0.0

  static (inside, dmz1) 10.0.0.0 10.0.0.0 netmask 255.0.0.0

• How to start Alerts notification to visitors using the DNS and IP society?

  1. I need to configure alerts for notification of visitor using the society of DNS and IP? How to do this?

  2 - second thing is what is the common use of DNS and IP society in the fields of account?

  Thank you

  Nabila,

  It is largely something E9 - the notification feature a much simpler with Profiler (Yes, there is a separate fee)

  without prospect Profiler: (I think I have the actual documentation at my office - will check once I'm back from #mme15 )

  1. go to settings, profiles of visitors, then change your display to show the fields you want to see.  Since you ask specifically about DNS and IP address, the view of the "technical information" is a good starting point.

  

  2. go into Setup and default user settings for users, configurations of Notification to visitors.  You can use the default or create new (lower right corner)

  Specify the view you want to use.  You can also create a custom for this notification by electronic mail header.

  3. go to settings, Notifications

  

  Configure your notification rules.

  

  for your second question - common use of DNS and IP name in the account fields, I don't think that there is a "common use" since the visitor record will show exactly the IP address and most organizations have a range of IP addresses, any sort of comparison of the visitor to the account is difficult.

  If your use case must match their account of visitors, e-mail domain is much easier.  Create a field on the Contact and account for the 'area of email address', a string manipulation cloud app to take the email address and delete everything before him ' @' accounts will be filled with the domain via a data load (or you can approach with a rule/validation rule set update to the name of the company (, remove the spaces and special characters and add with ".com")

  You could then: linking contacts to accounts using this field (will need to ensure that duplicate any record company) or use a rule of Match/deduplication to enter the values for the table of the company to update the contact. (or vice versa)

  I hope this helps.

• Crackling and static

  I just upgraded my iMac with OS X El Capitan. Now when I change my podcast, recorded in multi tracks, I hear crackling and static. When I export the file to a drive MP3 the problem isn't here. Any suggestions?

  Also, now when I switch back between wavelength and multitrack forms, it takes seconds to change (he used to make the quick switch) and the rotation color wheel appears during the shift.

  The attached note warning appears in a media window and hides. I wonder if it's related.

  You are using an external audio interface or map of its Apple built in?

  In any case, El Capitan, from all reports, was a disaster in terms of audio performance.  If you do not have the latest version of El Capitan, download the upgrade... It fixes some of the audo related issues.  (But, alas, not all.)  It is not just an audition... many DAW and audio hardware companies have issued warnings not to go yet.  Indeed, the last bug fix worked on hearing for most users.

  You can try to increase the latency/Buffer setting in Edition/Preferences/Audio Hardware.  There's a chance that might help.

  In addition, you may need to wait for the next difficulty of Apple bug... or downgrade to the previous version of the operating system.

• Extension drive DPS with executives and static libraries

  Y at - it any initiative within the roadmap for Adobe to allow their reader DPS extension in Xcode by use of frames and static libraries?

  Main features of the player could be related and distributed as a binary via static libraries.

  

  The shared resources of the DPS reader could be packed only a framework.

  

  Beyond the extension of the capacity of the drive, this would also enable advanced debugging and running on devices directly from Xcode.
