• 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

  permissible static route map 1

  corresponds to the IP 104

  access-list 104 refuse host ip 10.1.110.10 10.1.0.0 255.255.0.0

  access-list 104 allow the host ip 10.1.110.10 all

  IP nat inside source static 10.1.110.10 81.222.33.90 map of static route

  If the RIP is not absolutely necessary for you, try adding the default route to R2:

  IP route 0.0.0.0 0.0.0.0 172.16.2.1

  If you want to use RIP much, add permissions ACL 102:

• Problems with dynamic links between Premiere Pro and After Effects

  Hello

  dynamic binding (insertion of After Effects compositions on a Premiere Pro schedule) rarely worked properly since it was introduced. Problems vary (for example "media disconnected" made plates, old versions of comps rendered).

  What's worse, is that you can never tell what will be ultimately made out of Premiere Pro. Thus, a typical professional workflow to several projects together to finish during the day and batch overnight rendering can cause a catastrophe.

  Of course, the option is to not use dynamic link. Which makes then less competitive whole adobe.

  This subject has been widely discussed for years has been a dynamic links. I'm not the only one having this problem, and the problem is far from new.

  My only question is:

  Adobe: have you ever fix dynamic links?

  I don't really understand how you focus on software development in your company. The vast majority of the features of CC is little or not useful. The most important thing in a professional environment is consistent and reliable - performance can you please focus on that?

  I'm inspired to write this post because I just arrived in my edit at 07:00 only to find that my night makes is the wrong versions. All bed very well in the body and AE, damage the final rendering off Media Encoder used an older version of one of my compositions, and that I have nothing to send to my client.

  Janne

  Title edited by Kevin Monahan.

  Management of files Adobe seems to rely on the names and the last path of known files. Body loses links Dynamics (and other files) with frightening regularity in a situation where nothing has changed in the hierarchy of files, the files.

  16, when a hard disk of 8 GB was a huge drive, Pro Tools has been littering files on several disks because, as was the creation of audio files in real time, she had to. Digidesign introduced into a system which incorporated a unique program generated number in each file. Since that day I have never had a problem with lost files or correlate. I can move them anywhere, on any system and any PT session concludes that they are with total reliability - and we are talking about a lot of projects with thousands of files, through several studios. If you are looking for files, you can choose to use the identification number, the name of the file, the length of the file, or any combination of these. Which allows for the substitution of file.

  Until Adobe address this problem with a solution similar to that of Pro Tools, we'll be constantly beset by problems.

• IPSec VPN between Cisco ASA and Fortigate1000

  Hello

  I find a useful document on how to create a tunnel VPN IPSec with ASA 5510 firewall Fortigate 1000...

  the configuration of the coast FG is done without any problem, BUT the document (. doc FG) said I must configure the ASA with a GRE interface and assign an internal IP address in order to communicate with the FG...

  The question is: How do I configure the interface on the SAA ACCORD?

  Thanks in advance, Experts...

  Kind regards...

  ASA firewall does not support the interface/GRE GRE tunnel.

  If you need to have GRE configured, you will need to complete the GRE tunnel on router IOS.

  If you want to configure just pure tunnel VPN IPSec (lan-to-lan), here is an example of configuration on the side of the ASA:

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080950890.shtml

  Hope that helps.

• Problem with routing/circuits between SG300-10 and Dell Powerconnect 5224

  Hello

  I just bought a SG300-10 switch and loaded new firmware 1.27 on it.  Configure my VLAN and trunks, but I have a weird problem that I can't seem to understand.  It may be something small, I'm missing, but no matter, I have been scratching at it all day and I kicked in the butt.  If anyone can point me in the right direction or maybe something that someone see in my config which is wrong, I can get the terminology/theory wrong, after all, I just spent my CCNA :)

  My configuration:

  I have the SG300-10 as my switch and changed over to L3, so it may be my core of my small network.  On port 1, vlan 200 is configured as my unidentified native PVID and I put it to 210(LAN network) to trunk VLANs, 220 (management vlan) on the tag to the Dell powerconnect 5224 24port switch.  On port 1 of the Dell switch, I install as a trunk it as well with the same configuration (vlan native of PVID unidentified 200, 210 and 220 tag trunking).

  I have installed virtual interfaces on the SG300 for each VLAN (vlan 210 = 192.168.210.1/24, vlan 220 = 192.168.220.1/24) and on the Dell, since this is a feature of L2, I changed the vlan 1 to 220 management and assign the IP 192.168.220.2/24.

  Now, since the SG300 web interface, I ping IP management Dell (192.168.220.2/24)successfully and vice versa, can ping from Dell web interface to one of the IP of the bridge VLAN (210.1 & 220.1) successfully so that test, to me, looks like the Dell communicates with the SG300.)  I also have the default gateway of the Dell 192.168.220.1 printer value.

  Server IP: 192.168.220.10/24

  Workstation IP: 192.168.210.80/24

  Now the dilemma:

  I have a server plugged into switch port Dell 2 (configured as 'hybrid' because there is no option to access, value 220 PVID, vlan, worth 220 Untagged) and from the server, I can ping IP management dell very well switch and can ping the IP of the gateway of great SG300 so.  On the SG300 switch, on port 2, I plugged in a workstation (configuration is in access mode, vlan 210 unidentified) who can not ping the server plugged into the dell switch.  The workstation, I can ping all the SG300 interfaces and also the IP management dell but I can't ping the server.

  Any ideas anyone can provide is much appreciated!

  Edition of VLAN.

  Lenell, thank you for the call tonight. It seems that we have found the problem. The SIN, although it is configured with a default gateway, the gateway that brings 0.0.0.0. We also checked the NAS works from the same subnet to connect but fails outside of the subnet. Conversely, we checked 2 computers have no problem to connect through the VLAN level 3.

  I hope we got the right direction.

• Strange problem in IPSec Tunnel - 8.4 NAT (2)

  Helloo all,.

  This must be the strangest question I've seen since the year last on my ASA.

  I have an ASA 5540, who runs the code of 8.4 (2) without any problem until I ran into this problem last week and I spent sleepless nights with no resolution! Then, take a deep breath and here is a brief description of my setup and the problem:

  A Simple IPSEC tunnel between my 8.4 (2) ASA 5540 and a Juniper SSG 140 6.3.0r9.0 (road OS based VPN) screen

  The tunnel rises without any problem but the ASA refused to encrypt the traffic but it decrypts with GLORY!

  Here are a few outputs debug, see the output and a package tracer output that also has an explanation of my problem of NAT WEIRD:

  As you can see, there is no echo response packet at all because the package may not be wrapped while he was sent to.

  I'm Karen with it. In addition, he is a firewall multi-tenant live production with no problems at all outside this for a Juniper ipsec tunnel!

  Also, the 192.168.10.0/24 is another remote network of IPSec tunnel to this network of 10.2.4.0/28 and this IPSEC tunnel has a similar Juniper SSG 140 screen os 6.3.0r9.0 at the remote end and this woks like a charm with no problems, but the 171 is not be encrypted by the ASA at all.

  If someone could help me, that would be greatt and greatly appreciated!

  Thanks heaps. !

  Perfect! Now you must find something else inside for tomorrow--> forecast rain again

• Problem on the establishment of a GRE/IPsec tunnel between 2 cisco routers

  Hello world

  I am trying to establish a GRE IPsec tunnel between two cisco routers (2620XM and a 836).

  I created a tunnel interfaces on both routers as follows.

  2620XM

  interface Tunnel0

  IP 10.1.5.2 255.255.255.252

  tunnel source x.x.x.x

  tunnel destination y.y.y.y

  end

  836

  interface Tunnel0

  IP 10.1.5.1 255.255.255.252

  tunnel source y.y.y.y

  tunnel destination x.x.x.x

  end

  and configuration of isakmp/ipsec as follows,

  2620XM

  crypto ISAKMP policy 10

  md5 hash

  preshared authentication

  ISAKMP crypto key {keys} address y.y.y.y no.-xauth

  !

  !

  Set transform-set to_melissia

  match address 101

  2620XM-router #sh ip access list 101

  Expand the access IP 101 list

  match address 101

  836-router #sh access list 101

  Expand the access IP 101 list

  10 licences will host host x.x.x.x y.y.y.y

  Unfortunately I had no isakmp security associations at all and when I enter the debugging to this output.

  CRYPTO: IPSEC (crypto_map_check_encrypt_core): CRYPTO: removed package as currently being created cryptomap.

  Any ideas why I get this result? Any help will be a great help

  Thank you!!!

  I think it's possible. It seems to me that you are assuming that the address of the interface where goes the card encryption is peering address. While this is the default action, it is possible to configure it differently.

  As you have discovered the card encryption must be on the physical output interface. If you want the peering address to have a different value of the physical interface address outgoing, then you can add this command to your crypto card:

  card crypto-address

  so if you put loopback0 as the id_interface then he would use loopback0 as peering address even if the card encryption may be affected on serial0/0 or another physical interface.

• After the upgrade to Windows 8, problem with teredo tunneling adapter says code 10 error and the device cannot start

  Original title: teredo tunneling adapter error number 10 on windows 8

  on my acer travel mate 6292 which I just upgraded to windows 8 pro recently got a problem with teredo tunneling adapter.

  It says error code 10 and that the device cannot start, it made me unable to use wifi on my laptop

  I tried to reinstall the driver but it just says: windows encountered a problem installing and he says its error code 10

  Please help me

  Thanks in advance

  Hi Samuel,.

  We appreciate your efforts to solve this problem. We will put all our efforts in order to solve the problem.

  Teredo is a tunneling protocol designed to grant IPv6 connectivity to nodes that are located behind IPv6 NAT (network address translation) not compatible devices. It defines a way of encapsulating IPv6 packets in IPv4 UDP (User Datagram Protocol) datagrams can be routed through NAT devices, on the IPv4 internet.

  I wish to inform you that Acer has not released Windows 8 compatible drivers for Acer 6292 travel companion.

  I suggest you try to install the drivers for the card wireless in compatibility mode and check if it works. Check out the following link to download and install drivers in compatibility mode.

  Make the programs more compatible with this version of Windows

  http://Windows.Microsoft.com/en-us/Windows-8/older-programs-compatible-version-Windows

  The link below to download the drivers for the wireless card: http://us.acer.com/ac/en/US/content/drivers

  A Code 10 error is generated in the Device Manager in one of the following situations:

  1. the Device Manager cannot start the device.

  2. one of the pilots who needs the unit does not start.

  3 device Manager has sufficient information to recognize the error that spread upwards by the device driver.

  We could try following common resolutions to solve the problem:

  1. update the drivers for this device

  2 launch a service of automated troubleshooting

  3 contact material supplier technical support

  For more information, please see the following article:

  FIX: "this device cannot start" error Code 10 in the Device Manager in Windows

• IPSec tunnels between duplicate LAN subnets

  Hi all

  Please help to connect three sites with our Central site has all the resources for users, including internet access.

  The three sites will be the ASA 5505 like their WAN device.

  We need to know is - it possible, allowing to configure an IPsec Tunnel between the three ASA with duplicate LAN subnets.

  Central site two networks 192.168.1.x 24, 192.168.100.x 24

  Distance a 24 192.168.1.x subnet

  Two remote a subnet 192.168.100.x 24

  If it is possible we also do hair distance one ping, above two remote to the Central Site to access internet, what sites need are on the Central Site, including e-mail, network, other resource also records.

  We have no other way to make this network, as all security is on our Central Site, website filtering, Application filtering, filtering of network traffic all.

  We understand that we can change two remote sites to a different subnet from the Central Site, but we have so many host devices, it will take weeks or months, so to change the MS AD domain for all users, servers too.

  We really need your expertise to do this in a laboratory and then in production.

  Thank you

  Hello Stephen,

  You can check the following links for the subnets overlap talk to each other:-

  1 LAN-to-LAN IPsec VPN with overlapping networks

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080b37d0b.shtml

  2 IPsec between two IOS routers with overlapping of private networks

  http://www.Cisco.com/en/us/products/ps5855/products_configuration_example09186a0080a0ece4.shtml

  Important point is local network must connect to the remote network via the translated addresses.

  for example, you won't be ablt to use real IP of the communication.

  For haripinning or turning U:

  Hope that helps.

• NAT in the IPSec tunnel between 2 routers x IOS (877)

  Hi all

  We have a customer with 2 x 877 routers connected to the internet. These routers are configured with an IPSec tunnel (which works fine). The question is the inbound static NAT translation problems with the tunnel - port 25 is mapped to the address inside the mail server. The existing configuration works very well for incoming mail, but prevents users from access to the direct mail server (using the private IP address) on port 25.

  Here is the Config NAT:

  nat INET_POOL netmask 255.255.255.252 IP pool

  IP nat inside source map route INET_NAT pool INET_POOL overload

  IP nat inside source static tcp 10.10.0.8 25 25 expandable

  IP nat inside source static tcp 10.10.0.8 80 80 extensible

  IP nat inside source static tcp 10.10.0.8 443 443 extensible

  IP nat inside source static tcp 10.10.0.7 1433 1433 extensible

  IP nat inside source static tcp 10.10.0.7 extensible 3389 3389

  allowed INET_NAT 1 route map

  corresponds to the IP 101

  access-list 101 deny ip 10.10.0.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 101 permit ip 10.10.0.0 0.0.0.255 any

  On the SAA, I would setup a NAT exemption, but how do I get the same thing in the IOS?

  See you soon,.
