• 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

• VPN site to Site with NAT and Port forwarding on a 871

  Hello

  Could someone please look at the config 871 router attached and tell me where I'm wrong!

  VPNs all work, work, BUT anyone trying to connect to a port that is sent through the VPN port forwarding fails.

  In the config attached Port 3389 (RDP) is sent to an internal server, if you connect to the external interface Internet connection is made and it works well, but if someone tries to connect to the IP address internal to that same server through VPN, it does not.

  We've added commands to stop working on the lines VPN NAT, but these do not seem to work.

  What Miss me?

  Thank you in advance and I will adjudicate all useful responses.

  It is a common problem. Yes you added controls to prevent NAT to work above the tunnel, but your static nat port to port 3389 takes precedence over the generic nat command, and there not all orders top to prevent it is nat would be above the tunnel.

  I wrote an example configuration for this some time, see here for more details:

  http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a0080094634.shtml

  If all goes well, he explains everything. Note that it is for a general order static host, not a static port that you have, but the concept is exactly the same. Just add a statement roadmap on the end of your static command of the port, and this route map - will reference an ACL that denies are used when going up above the tunnel.

• Anyone know of any compatibility issues with Windows 8 and RV series routers?

  I have a small network with a laptop computer, Windows 8, Windows XP desktop computer and a network MyBookLiveDuo storage device. I have sharing enabled between these devices. Everything worked well on a network switch. I replaced the switch with the RV110W VPN Firewall Router to add better security to my network before I have expand it. Since then, I have a laptop Windows 8 intermittent connectivity while the connectivity of the XP desktop computer shows no problem.

  On the laptop Windows 8 I ran network troubleshooting, and he complained that two devices on the network are (NAT) network address translation and the symptoms he describes is what I see. Problem is that I don't have a network Analyzer to look at the network in more depth. I looked online for the RV110W documentation and if NAT is listed as one of the characteristics, there is no discussion in the documentation on how to manage this feature in the router.

  I can connect to the Windows 8 laptop from Office XP and access shared content. I can connect to the Duo since Office XP without difficulty. However, except when they reappear periodically under the heading of my network in Explorer on the laptop Windows 8, I can't access the Office XP or the Duo of the laptop Windows 8. Curiously, however, I have a part of the Duo mapped as a network drive on the laptop Windows 8 and I can access it even when everything else has gone. Also, the interface of management for the Duo appears on the laptop Windows 8 and I can access the Duo to manage. Only, I can't access the shares on the Duo. Then all of a sudden they reappear under network in the file Explorer and I can then access. I think it must have to do with NAT, but I can't find anything out about it.

  If it's something I can turn on the router long enough to see if the problem goes away I would like to try, but I can't find it in the documentation, and I can't find it when I look aroiund in the management interface.

  The fact that I am not having the form of the XP desktop computer problem makes me think that a compatibility issue with Windows 8. Does anyone know if Windows 8 did anything with NAT? I try to get help from Microsoft Technical Support, but their level 1 tech told me to call Tech Support Pro when they open later this morning. Support cat Cisco won't open until Monday at 09:00.

  Also, throughout this connection problem Internet from the laptop through the router is never interrupted. It's strictly connectivity with other devices on the internal network that comes and goes.

  Hi Gregg,

  NAT must not play unless your applications on the internet. The "port Internet" or "WAN port" is a NAT port that converts your public IP address from ISP to your LAN subnet addresses. NAT allows multiple computers on a network to use 1 public IP address.

  If your devices are connected to the Ether "LAN ports" they are not affected by NAT unless they are Web applications. 4 'LAN ports"are 2 layer switch ports. This means that all local requests are forwarded by the switch ports.

  This device did replace exactly? The XP computers, DUET and window 8, make these products using the static IP address or you allow the RV110 to assign an IP address automatically? What IP address you are using on the LAN of the RV110?

• Application of VPN S2S (with NAT)

  Hello experts,

  ASA (8.2) and standard Site 2 Site Internet access related configs.

  Outside: 1.1.1.1/24-> peer IP VPN S2S.

  Inside: Pvt subnets

  Standard "Nat 0' orders and crypto ACL for our remote offices, local networks with IP whp program.

  Requirement:

  Need to connect the PC to external clients (3.3.3.3 & 4.4.4.4) on tcp/443 via vpn S2S on our LAN. Client only accepts only the host with public IPs.

  I need NAT to my internal IP to the public IP say 1.1.1.2 and establish the VPN tunnel between 1.1.1.1-> PRi Client-side & secondary IPs (Cisco router).

  (without losing connectivity to remote offices). No policy NAT work here?

  ex:

  My Intern: 10.0.0.0/8 and 192.168.0.0/16
  Assigned IP available for NAT (some time to connect to the client only): 1.1.1.5

  External client LAN IPs: 3.3.3.3 & 4.4.4.4

  Outsidemap 1 crypto card matches the address CRYPTO
   
  Customer will undertake to peer with IP 1.1.1.1 only.

  Do I need a ' Nat 0' configs here?

  Also, for the specifications of the phase 2, it is not transform-set options gives. Info given was

  Phase2: AH: people with mobility reduced, life: 3 600 s, PFS: disabled, LZS Compression: disabled.
  This works with options of the phase 2?

  Thanks in advance

  MS

  Hello

  «Existing NAT (inside) 1 & global (outside) does not interfere with NAT 5 when users try to reach the ClientLAN.»

  Your inside nat index is '1', while the dynamic policy-nat is index '5 '.

  "" For the phase 2 in general, we define Crypto ipsec transform-set TEST ".

  Sure, the remote tunnel peers even accept transform set, everything you put up with the example below and distant homologous put the same tunnel.

  Crypto ipsec transform-set ESP-AES-128-SHA aes - esp esp-sha-hmac

  "In this scenario, no need to define any what and just add empty transform don't set statement under card crypto?

  No you need a defined transformation.

  "3. If we want to limit the destination port 443, I need to use separate VPN filters?

  That's right, use a vpn-filter.

  "4. we have several phase 1 configs, but wanted to use AES256 & DH5 (new policy)"... for s2s, these options work fine. ""

  Of course, you have set the phase 1, as required.

• 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.

• Identity firewall does not work with NAT

  We implement an environment that restrict access to Internet with rules based on users and groups to Active Directory.

  There were many difficulties, but the current state is:

  -The 'Test' of the firewall server-> identity Options results GOOD group

  -The 'Test' of Agent of Active Directory on Windows-> identity Options GOOD results

  -The rules we applied on the inside Firewall identity-based Interface are no "respected".

  The environment:

  -We have two ASA 5520 to failover.

  -There are four contexts in this pair of ASA.

  -Now we are activating the firewall of identity in a context.

  -Of course, the AD are in one of the inside of this context, networks.

  On the Configuration Guide of the identity of Firewall, to

  http://www.Cisco.com/en/us/docs/security/ASA/asa84/asdm64/configuration_guide/access_idfw.html#wp1349541

  We have seen that there are a lot of features that are not supported:

  ...

  The following features of ASA do not support the use of the object based on the identity and the FULL domain name:

  Route-map

  -Crypto card

  -WCCP

  -NAT

  -Group (except filter VPN) policy

  -DAP

  ...

  When using NAT does not, just remove NAT.

  How to configure this feature? Identity with NAT work?

  This is the reason why you have not any user ip in ASA mappings.

  Domain configured in ASA name must be the netbios domain name and it must be matched with one that you see 'adacfg dc list' output, otherwise ASA will drop all user agent AD ip report.

  You can have a try with the following new configs.

• Assign a static IP to guest with NAT Virt network adapter?

  I'll put up a * nix VM that I want to give out-bound network connectivity, but I want to make its services available only on my local machine (for example MySQL).  VMWare Player with NAT assigned a DHCP address, but because it is not update my host name resolution, to access a service on the client, I need to use the IP address.

  I would like to assign a static IP address on the guest, so I can add an easy to use in the host of my host file.  I can update my guest network interface file to not assign no problem.  I'm worried that I can use an IP address that overlaps the VMWare DHCP pool (and may occur a conflict of address when I turn on a new virtual machine), or outside the range of the virtual switch.

  Is this possible with VMWare Player, and is there something in the configuration files, that I might be able to change this?

  Default 192.168.x.1 address is used for the adapter to the virtual host, 192.168.x.2 as the address of the NAT gateway and 192.168.x.128... 254 for DHCP, which means that you can assign static IP addresses between 192.168.x.3 and... 127.

  However, you can configure rather a reserve in the vmnetdhcp.conf file by adding for example

  host LuckyLuke {}
  Hardware ethernet 00: 0C: 29:23:b6:12;
  fixed-address 192.168.156.77;
  }

  just in front of the brand ' # end ' . Please replace "156" by your own subnet. In the example above, the VMS with MAC address "00: 0C: 29:23:b6:12" will receive the IP "192.168.156.77". BTW. hostname (in this case "LuckyLuke") does not matter, it must just be unique in the file.

  You have placed your beam to insert at the end of your text on page 13 and then apply Insert menu: Page Break? In the v5.6.2, Pages I just add a new page to a section of four pages to this approach.

• How can implement you not with Tim Capsule and AirPort their simulation on the iMac?

  Hello

  How can implement you not with Time Capsule and AirPort their simulation on the iMac?

  I don't know what you're asking.

  AirPort Extreme is a wireless router.

  A Time Capsule airport is an AirPort Extreme with a built-in hard drive for data storage.

  An iMac is a Mac computer.

  An iMac is not a wireless router, so he is unable to perform the functions of a wireless router.
