• 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

  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

• Issue of 8.3 to 8.2 NAT VPN SSL

  In the study and test SSL VPN on a SAA, I have the network as shown in the attached diagram. The configuration is the result of an ASA with 8.3 but our ASA is 8.2 and at this time I am not familiar with the new NAT configuration and controls in 8.3 or later and wondering if anyone can translate the

  «nat source (indoor, outdoor) static ' for me at a 8.2 version.»

  Appreciate any help.

  Hello

  This seems to be a NAT0 / NAT exempt in the new 8.3 + NAT format configuration

  And I guess it would make sense that we are talking about VPN connections.

  It should be something like this

  the INTERIOR-NAT0 192.168.3.0 ip access list allow 255.255.255.0 192.168.100.0 255.255.255.0

  NAT (inside) 0-list of access to the INTERIOR-NAT0

  Naturally the names/networks used in the configuration can be different depending on your existing actual configurations on the firewall.

• I can't have a log and snmp in vpn

  Hello

  I can't have a log and snmp in vpn when I want to achieve the management interface, or remote access to asdm and ssh is strange ok.it for your help thank you.

  Best regards

  If you want to access the ASA via a VPN connection, you would not use (or should use) NAT.  You only need to add command -access to the administration .

  So let's say you want to use the IP address associated with the interface named inside of handle the ASA.  Then you go inside management-access command

• 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.

• initializer, instance and static initializer blocks

  Hi guys,.
  
  I have read the foregoing, mentioned in the JLS and also in a book before, but I still do not understand, what is the use of these. I have sort of a rough idea, but not exactly. I mean, what is the purpose of the initializer for instance and static initializer blocks, how can be useful? I understand that I can run pieces of code that initialize instance and static variables accordingly, but what is the difference then to use a constructor to initialize these areas? Are these pieces of code executed before the execution of any manufacturer, or when otherwise?
  
  Sorry for my noob, I learn.
  
  PR.

  Static initializer blocks are executed when the class is loaded, once (a classloader). So that they have some use. Initializers for instance differ a lot of builders (I think that code in the initializers of the instance has been copied to each manufacturer), but they can be useful with anonymous inner classes for example (since you cannot define constructors it (well, you can, but you can't call them)).

  They have a limited use, but it is good to recognize them if you see them.

• Public static political static NAT in conflict with NAT VPN

  I have a situation where I need to create a VPN site-to site between an ASA 5505 using IOS 7.2 and a Sonicwall NSA4500. The problem arises where the LAN behind the Cisco ASA has the same subnet an existing VPN currently created on the Sonicwall. Since the Sonicwall cannot have two VPN both run on the same subnet, the solution is to use policy NAT on the SAA as well as for the Sonicwall, the new VPN seems to have a different subnet.

  The current subnet behind the ASA is 192.168.10.0/24 (The Sonicwall already has a private network virtual created for another customer with the same subnet). I try to translate it to 192.168.24.0/24. The peer LAN (behind the Sonicwall) is 10.159.0.0/24. The ASA relevant configuration is:

  interface Vlan1

  IP 192.168.10.1 255.255.255.0

  access extensive list ip 192.168.24.0 outside_1_cryptomap allow 255.255.255.0 10.159.0.0 255.255.255.0

  list of access VPN extended permit ip 192.168.10.0 255.255.255.0 10.159.0.0 255.255.255.0

  public static 192.168.24.0 (inside, outside) - list of VPN access

  card crypto outside_map 1 match address outside_1_cryptomap

  In addition, there are other static NAT instructions and their associated ACLs that allow certain traffic through the firewall on the server, for example:

  public static tcp (indoor, outdoor) interface smtp SERVER smtp netmask 255.255.255.255

  The problem is this: when I enter the static strategy statement NAT, I get the message ' WARNING: real-address conflict with existing static "and then it refers to each of the static NAT statements reflecting the external address to the server. I've thought about it, and it seemed to me that the problem was that policy NAT statement must be the first statement of NAT (it is the last one) so that it is run first and all traffic destined to the VPN to the Sonicwall (destination 10.159.0.0/24) tunnel would be properly treated. If I left him as the last statement, then the other static NAT statements would prevent a part of the 10.159.0.0/24 network-bound traffic to be correctly routed through the VPN.

  So, I tried first to my stated policy NAT upward in the ASDM GUI interface. However, moving the declaration was not allowed. Then I tried to delete the five static NAT statements that point to the server (an example is above) and then recreate them, hoping that would then move up the policy statement NAT. This also failed.

  What Miss me?

  Hello

  I assumed that we could have changed the order of the 'static' , the original orders, but as it did not work for some reason any then it seems to me that you suggested or change, that I proposed should work.

  I guess that your purpose was to set up static political PAT for the VPN for some these services, then static PAT of public network access, then static NAT to policy for the rest of the network in-house.

  I guess you could choose any way seems best for you.

  Let me know if get you it working. I always find it strange that the original configuration did not work.

• NAT VPN tunnel and still access Internet traffic

  Hello

  Thank you in advance for any help you can provide.

  I have a server with the IP 192.168.1.9 that needs to access a subnet remote from 192.168.50.0/24, through the Internet.  However, before the server can access the remote subnet, the server IP must be NAT'ed to 10.1.0.1 because the VPN gateway remote (which is not under my control) allows access to other customers who have the same subnet address that we do on our local network.

  We have a 2801 Cisco (running c2801-advsecurityk9 - mz.124 - 15.T9.bin) set up to make the NAT.  It is the only gateway on our network.

  I have configured the Cisco 2801 with the following statements of NAT and the relevant access lists:

  access-list 106 allow host ip 192.168.1.9 192.168.50.0 0.0.0.255

  NAT extended IP access list
  refuse the host ip 192.168.1.9 192.168.50.0 0.0.0.255
  deny ip 192.168.1.0 0.0.0.255 192.168.3.0 0.0.0.255
  ip permit 192.168.1.0 0.0.0.255 any

  route allowed ISP 10 map
  corresponds to the IP NAT

  IP nat EMDVPN 10.1.0.1 pool 10.1.0.1 netmask 255.255.255.0
  IP nat inside source list 106 pool EMDVPN
  IP nat inside source map route ISP interface FastEthernet0/1 overload

  When the server (192.168.1.9) attempts to ping on the subnet of 192.168.50.0/24 devices, the VPN tunnel is established successfully.  However, after that, the server is no longer able to access the Internet because the NAT translation for 192.168.1.9 has changed since the external IP address of the router (FastEthernet0/1) at 10.1.0.1.

  The documentation I've seen on the site of Cisco says that this type of Setup allows only host subnet communication.  Internet access is not possible.  However, maybe I missed something, or one of you experts can help me.  Is it possible to configure the NAT router traffic destined to the VPN tunnel and still access the Internet by using the dynamic NAT on FastEthernet0/1?

  Once again, thank you for any help you can give.
