2 static NAT on the same Interface

Similar Questions

• Multiple outside NAT at the same internal IP address

  In my view, the answer is no, but wanted to check.

  Can I have multiple NATs on the same interface to a single internal IP?

  For example.

  static (inside, outside) a.a.a.2 10.20.30.248 netmask 255.255.255.255

  static (inside, outside) a.a.a.3 10.20.30.248 netmask 255.255.255.255

  Where the subnet and the IP block is also on for two external NATs.

  Hello

  If you try to do the following:

  definition of the IP 10.20.30.248 to a.a.a.2

  and

  definition of the IP 10.20.30.248 to a.a.a.3.

  Learn to translate the internal ip address to two external ip addresses. If Yes, then this is not possible.

  I hope this helps.

• Static and dynamic NAT at the same time?

  Is this possible? Let's say you have 20 public address pool and you have 30 computers LAN. You want to assign the same public address for some of the servers. And the rest can get the addresses of the pool at random.

  It would be nice if we can easily do the appropriate firewall rules.

  Yes, it is possible, you can use nat and global commands for dynamic conversion and use the static commands for static translation at the same time.

  Here is an example:

  Public rate IP-range outdoors: xxx.xxx.xxx.0/27

  (IP addresses are xxx.xxx.xxx.1 - xxx.xxx.xxx.30)

  Private range of IP addresses on the inside: yyy.yyy.yyy.0/24

  In the example I'm going to static translate xxx.xxx.xxx.2 to yyy.yyy.yyy.2 Server1 (ditto for server2, but by using adresse.3)

  All other IP addresses is translated dynamics.

  Here is an example of how you can do this:

  IP address outside xxx.xxx.xxx.1 255.255.255.224

  IP address yyy.yyy.yyy.1 255.255.255.0 inside

  NAT (inside) 0 access-list sheep

  NAT (inside) 1 yyy.yyy.yyy.0 255.255.255.0

  Global 1 interface (outside)

  public static yyy.yyy.yyy.2 xxx.xxx.xxx.2 (indoor, outdoor)

  public static yyy.yyy.yyy.3 xxx.xxx.xxx.3 (indoor, outdoor)

  access-list deny ip host yyy.yyy.yyy.2 sheep all

  access-list deny ip host yyy.yyy.yyy.3 sheep all

  access-list sheep ip allow a whole

• How to get the ASA packets that come in and out on the same interface?

  Hi all

  How can I configure the ASA5520 routes the packets that come in and out on the same interface? I ve more than 1 network behind the camera of the SAA. It s separated by internal router. They can communicate with each other.

  I've seen it's PIX design problem. She applies to the platform of the ASA?

  Please advice.

  Thank you

  This golden rule remains immutable. the only exception is the vpn traffic. ASA for example (or pix v7) would act as a hub for traffic between two rays rediect vpn.

  regarding your question.

  Internet <-->asa <-->1 <-->lan router <-->lan 2

  assuming the host to lan 1 to asa as the gateway default, even asa has a static route to the internal router of the point for local network 2, the golden rule will reject this operation.

  one solution is to re - configure the dhcp on the LAN 1 scope and make the internal router as the default gateway; and the internal router has the asa as the default gateway.

• Need help for reading in parallel on the same interface and writing XNET

  Hello. I need help to configure CAN interface to write and read from the same interface.

  I use NI PXI-8513/2. I use CAN1 as interface.

  My had TO send status messages CAN every 100ms. I have to read in order to return akntoowlege to keep DUT CAN interface happy and not make mistakes.

  So, I want to open Strim Session and readall frames in the loop. At the same time, I need to be able to write in a frame HAD at the time...

  I only need to read one picture at a time too, but since I know the ID, I can pull it from the stream.

  What I'm confusing all is how to put in place the same CAN1 interface to be able to write and read in parallel.

  I think I would get errors that interface is already in use.

  Since I'm new to CAN, I was read and write only when necessary. But, sometimes I was getting errors on my messages. Sometimes I get message, sometimes miss me. But, when I run CAN test criminal as sniffer he sends and written every time. I was told it's because it recognizes all messages.

  I opened to suggestions of how best to implement the interface.

  I guess I can use CAN2 and separator to work around this problem, but I would use an interface if possible.

  Thank you

  Hi Rus,

  The XNET hadrware takes care of most of the low level of detials for you. The reading and writing of the circuits are both connected to the bus at any time. When you write to the hardware it will try to put a frame on the bus at the first opportunity he can. If the frame loses arbitration material re - will attempt to send the frame up is successful. Reception equipment monitor activity on the bus, regardless of what it conveys. The material received will usually throw a framework that was sent by communication equipment, but there is an Echo property pass to circumvent this behavior too.

  Take a look at the example of the expedition: MAY-> NI - XNET-> Sessions-> multiple Sessions Intro-> CAN even exit entry framework Port unique Point.vi. Keep in mind that this example you will need to use a second CAN interface to recognize frames, it transmits. I would recoment against the example CAN output Frame Single Point which would mimic your ECU if you choose a type of cyclic frame running this example.

• JIT - ACM with two Instance of the Ethernet on the same interface Service

  Hi all

  I develop script of EEM for platform of ASR903... I would define VCA two, one for each 'host' connected to the same interface of ASR903 (GI 0/1).

  Ah, ethernet OAM.  I've never used the detector of this event, so I don't know what capabilities are available.  I don't have a handy to test myself ASR903.  You can run the command "show event handler detector ethernet detail" to see what built-in variables are available to your EEM ethernet event policy.  You can also do "display event handler detector all ' to see all detectors of the event.  I hope you see something out there that specifies the VCA.

  If this isn't the case, you certainly could extract something like a syslog message if a message is generated that contains the name of EVC.  Still, I don't know what syslogs are generated, so you should test yourself.

• WebVPN and anyconnect on the same interface

  Hello!!

  We have ASA 5520 firewall running with code.9.1 (2). We already have webvpn running on the firewall and has active users to use it. Now, the client came with a new requirement to configure firewalls on the same anyconnect. We have installed VPN more premium license.

  (1) is it possible to enable webvpn and anyconnect on the same interface. If Yes, what are the aspects we must consider to allow them both on the same interface?

  (2) how much webvpn and anyconnect vpn licenses should I do with my premium lincense?

  Please help on this.

  shver attached for reference.

  Best regards

  Sri

  Your peers licenses AnyConnect Premium gives you the right to access SSL VPN without customer and focused on the customer.

  Licensing is based on the concurrent users so regardless of the simultaneous dosing will work - as long as the number of connected does not exceed 100.

  Your site to site VPN IPsec does not count against this permission, but is rather against "Other peer VPNS" which does not require a separate license and is limited by the capacity of the ASA equipment (750 on your platform).

• Public and private IPs on the same Interface by using NAT Exemption/policy NAT

  I'm looking for some feedback on whether my thoughts on the installation program will run.

  Equipment: PIX 515E 6.2 (2)

  Scenario:

  The inside interface of the PIX will host 3 blocks of addresses IP - 24 public 2 blocks and 1 private/16 block. (All IP addresses have been replaced by dummy blocks.)

  Blocks of audiences:

  * 192.168.10.0/24

  * 192.168.20.0/24

  Block of private:

  * 10.50.0.0/16

  Traffic from the public 2/24 blocks should go through the firewall without address translation.

  The two blocs of the public will be able to receive connections initiated from the Internet.

  Public blocks will need to be able to send and receive traffic on a static VPN tunnel to our headquarters without subject to address translation

  Traffic leaving the sector private/16 block should be subjected to PAT before passing through the firewall.

  Private/block 16 will not receive incoming traffic from the Internet (other than responses to outbound connections initiated from within the private block).

  However, the private block will also have to be able to send and receive traffic on a static VPN tunnel to our headquarters * without * subject to address translation (i.e. hosts on our corporate network must be able to initiate connections to the private block and vice versa).

  The inside interface of the PIX will be connected to a Catalyst 3xxx series layer 3 switch, which will be responsible for routing all internal (so the PIX will never be routing of traffic on the interface, it was received).

  My ideas on how to implement are:

  * Use the exemption of NAT to exempt public address translation blocks. This will allow incoming and outgoing connections through the firewall.

  * Use the exemption of NAT to exempt the block private NAT when connecting to our head office on the VPN tunnel.

  * Use policy NAT w / PAT to translate the block private connecting to all other hosts.

  I have translated these thoughts in the following configuration snippet.

  Because the NAT exemption is processed before policy NAT in the evaluation of the NAT rules, I believe that this should allow the public IP blocks treat incoming/outgoing traffic without translation, while submitting the private translation block (except during handling of incoming/outgoing connections to our network of corporate office).

  Can someone confirm my assumptions about this?

  # ----------------------------------------------------------------------

  traffic of # which should be exempted from translation

  permit ip 192.168.10.0 access list nat_exempt 255.255.255.0 any

  nat_exempt 192.168.20.0 ip access list allow 255.255.255.0 any

  nat_exempt ip 10.50.0.0 access list allow 255.255.0.0 10.100.0.0/16

  traffic of # which should be the subject of translation

  policy_nat ip 10.50.0.0 access list allow 255.255.0.0 any

  # Suppose 192.168.5.1 is the address to use for PAT

  Global (outside) 1 192.168.5.1

  NAT (inside) 0-list of access nat_exempt

  NAT (inside) 1 access-list policy_nat

  # assumes that 192.168.10.7 is the IP address of the inside layer 3 switch

  Route inside 192.168.10.0 255.255.255.0 192.168.10.7 1

  Route inside 192.168.20.0 255.255.255.0 192.168.10.7 1

  Route inside 10.50.0.0 255.255.0.0 192.168.10.7 1

  #assume the following configuration sections appear elsewhere: static tunnel VPN, ACL, ifconfig, etc..

  # ----------------------------------------------------------------------

  Yes, this will work, even if you don't need political NAT for the 10.50.0.0 network. For PAT the 10.50.0.0 network when to anywhere (except via VPN) just do:

  Global 1 192.168.15.1 (outside)

  NAT (inside) 1 10.50.0.0 255.255.0.0

  As I said, you have works perfectly, the above is just an easier way to do it.

• DHCP and static IP at the same time?

  Simple scenario. My internet connection using DHCP and my home network uses a 10.x.x.x (static) addresses. How can I add an address static 10.0.0.x, in addition to the IP address provided by DHCP, if I can use internet and LAN at the same time? Under linux, it's pretty simple: ip addr add 10.0.0.1/24 dev eth0

  You cannot use two IP addresses on a single ethernet interface, if you are using DHCP, you cannot add a static IP, it is technically impossible, in this case you must use two NICs, i.e. two different interfaces. If you connect to the Internet via the DHCP protocol and you have another PC which allows you to build a local network then you you may not change the dynamic address, but can replace the LAN address is dynamic/static. For example, if the PC that has the Internet connection, add another NETWORK card, then connect the second PC with this new NIC card. Now turn on sharing on the first PC Internet connection interface and so the two PC will be able to run the home networking and Internet connectivity. You don't even need to add a static IP address.

• Using the same interface CAN read and write

  Hello.

  Can I use the same CAN interface to read and write?

  For example:

  I send you CAN frame using CAN1 to my MCU.

  IF MCU confirmed the order of receiver it immediately sends the echo return command and there different ID to send the command.

  I tried to use CAN1 output framework and then reconfigures CAN1 to frame in queue and retrieve the frame of the echo.

  But it seems that I was always missing. The 'framework of CAN' kept vi expire.

  When I used the separator on the outlet BOX in my configured MCU CAN1 for frame and CAN2 for chassis in and I managed to catch the echo framework.

  I think about 100 ms for the frame in response that will be sent after the order has been received. It takes longer for the NI PXI-8513 reconfigure? Can I still do it, or I have to use the separator?

  I wad jump to use an interface to read and write.

  Thank you

  Ok. I misread your notion of echo. I understand now. I'm sorry.  The code you posted seems reasonable.

  (1) did you notice on or off for the session?

  (2) what baud rate? You can add a parameter of baud rates for the property to be explicit node.

  (3) I don't remember the name of VI, but you can add a status of Comm Get after reading. This will give you some information about the bus - if errors were detected, etc. Which can be useful to help debug.

• public static IP on the same subnet of both internet and local

  I need to configure my little guy with ip static on the same subnet on the side of the router/internet and the side room, but it does not.

  I will allow me to dhcp on the side of the router/internet and then statically assign an ip address from the same subnet on the local side, but then it does not pass on my dhcp server dhcp queries.

  suggestions?

  Yes. Configure the WRT with a LAN inside your main LAN IP address. Disable the DHCP server on the WRT. Wire then a main WRT to your local area network LAN port. Do not use the internet port on the WRT.

• Static NAT with the road map for excluding the VPN

  We have problems of access to certain IPs NATted static via a VPN.  After some research, we have learned that you have to exclude traffic destined for the VPN to the static NAT using a road map. So we did this:

  10.1.1.x is the VPN IP pool.

  access-list 130 refuse ip 192.168.1.0 0.0.0.255 10.1.1.0 0.0.0.255
  access-list 130 allow ip 192.168.1.0 0.0.0.255 any

  sheep allowed 10 route map
  corresponds to the IP 130

  IP nat inside source static 192.168.1.5 1.1.1.1 sheep map route

  Above worked to fix the VPN but the IP 192.168.1.5 is no longer publicly available via 1.1.1.1.  What seems to happen, is that the static NAT is not really work and this IP address is NATted with the IP of PAT.

  Any ideas on how to get this to work?

  Thank you
  Diego

• GRE and IPSEC VPN tunnel over the same interface

  My client is currently connected to a service provider of call through a GRE Tunnel over IPSEC. They chose to move all connections to a VPN site-to-site traditional behind a firewall, here, to your corp office.  As the questions says, is possible for me to put in place the VPN site to site on the same router? Interface Tunnelx both ethernet have the same encryption card assigned to the destination router.  I thought that traffic could divide by identification of traffic 'interesting '.  Thanks for all the ideas, suggestions

  Ray

  Ray

  Thanks for the additional information. It takes so that the existing entries in ACL 101 remain so the existing tunnel will still work. And you have to add entries that will allow the new tunnel. Editing an ACL that is actively filtering traffic can get complicated. Here is a technique that I use sometimes.

  -create a new access list (perhaps ACL 102 assuming that 102 is not already in use).

  -Copy the entries of ACL 101 to 102 and add additional entries you need in places appropriate in the ACL.

  -Once the new version of the ACL is complete in the config, then go tho the interface and change the ip access-group to point to the new ACL.

  This provides a transition that does not affect traffic. And he made it back to the original easy - especially if something does not work as expected in the new ACL.

  If the encryption of the remote card has an entry for GRE and a separate entrance for the IPSec which is a good thing and should work. I guess card crypto for GRE entry specifies an access list that allows the GRE traffic and for IPSec crypto map entry points to a different access list that identifies the IP traffic is encrypted through the IPSec tunnel.
