• VPN site-to-site between two PIX 501 with Client VPN access

  Site A and site B are connected with VPN Site to Site between two PIX 501.

  Also, site A is configured for remote access VPN client. If a remote client connects to Site A, it can only get access to the LAN of Site A, it cannot access anything whatsoever behind PIX on Site B.

  How is that possible for a VPN client connected to Site A to Site B?

  Thank you very much.

  Alex

  Bad and worse news:

  Bad: Not running the 7.0 series PIX cannot route traffic on the same interface, the traffic is recived. Version 7.0 solves this ipsec traffic.

  Even worse: PIX 501 can not be upgraded to 7.0...

  A couple of things to think about would be the upgrade to hardware that can run the new IOS or allowing a VPN R.A. on site B.

  HTH Please assess whether this is the case.

  Thank you

• Try to set up a direct parallel connection between two computers in Windows XP Home edition

  I tried to set up a direct parallel connection between two computers in Windows XP. I have the right cable (CAT 5 Ethernet connection) and you can set up the connection on my own laptop, but when I go through the installer on another laptop it create new connection-establishment of advanced connection--> when the next window opens asking me to choose between "accept incoming connections" and "connect directly to another computer" (which I need to select) for the second option is grayed out and not can not be selected.

  The same thing happens when I try to implement the same connection between my laptop and the desktop we have. All of these computers are running on Windows XP service pack 2. I really need help with this because I'm about to start pulling my hair.

  Hello

  I want to create a connection between two BlackBerry 7290 with OS 4.1 I found something with BluetoothSerialPort, but if I pair the und devices 2 start the application I get no BluetoothSerialPortInfos with the static method of the BluetoothSerialPort class.

  When you pair the Bluetooth devices, they exchange a list of services they support.  This means that you will need to have a server side application up and running which listens to the incoming Bluetooth connections before they are matched.  Otherwise, the other Bluetooth device will not know about your application and will not be able to connect to it.

• Connectivity between two nodes of Virtual Box

  For a few days, I try to establish the network connectivity between two nodes OEL (Oracle Enterprise Linux) in Oracle Virtualbox. I tried everything I have found Google, but still nothing works, everytime I try to ping from one node to another node Hostname/IP is showing unknown host. All the advice everyone here will be great for me.
  
  Published by: 918868 on October 30, 2012 02:30

  When you create a virtual machine, by default VirtualBox allows virtual network card and selects the "Network Address Translation" (NAT) mode for it. In this way the guest can connect to the outside world using the networking of the host and the outside world can connect to services on the feedback that you choose to make visible outside of the virtual machine.

  This default configuration is good probably 95% of users of VirtualBox. VirtualBox is, however, extremely flexible in how it can virtualize networks. It supports multiple virtual NICs per virtual machine, the first four that can be configured in detail in the Manager window. Additional network cards can be configured on the command-line with VBoxManage.

• Problem set up RV connection between two sites

  Dear all,

  I'm putting a replication for some virtual machines from the production site to a recovery site. The two sites are on ESXi with vCenter 5.5 5.5 with their own AD domains. The connection between them is done with customer VPN Cisco of DR site in Production site.

  I installed SRM 5.5.1 on two places and I was able to successfully combine the two sites. The State of them is CONNECTED on both sites. On both environments, I deployed unit of replication vsphere and that they are properly registered on the two vCenters.

  The problem is that when I try to configure the connection of VR, I get the following error:

  VRM Server generic error. Please see the documentation for troubleshooting information. The detailed exception is: '"HmsServiceInstance" thrown an unexpected exception "java.net.UnknownHostException' with message 'siteB.dns.name' when calling method of managed objects' getContent".

  I get this error from two different points.

  I can't do a ping on the two sites using the FULL domain name and I've tried the following article:

  Could you please help me solve this problem.

• The VPN client VPN connection behind other PIX PIX

  I have the following problem:

  I wanted to establish the VPN connection the client VPN to PIX on GPRS / 3G, but I didn t have a bit of luck with PIX IOS version 6.2 (2).

  So I upgraded PIX to 6.3 (4) to use NAT - T and VPN client to version 4.0.5

  I have configured PIX with NAT-T(isakmp nat-traversal 20), but I still had a chance, he would not go through the 1st phase. As soon as I took nat-traversal isakmp off he started working, and we can connect to our servers.

  Now, I want to connect to the VPN client behind PIX to our customer PIX network. VPN connection implements without problem, but we can not access the servers. If I configure NAT - T on the two PIX, or only on the customer PIX or only on our PIX, no VPN connection at all.

  If I have to connect VPN client behind PIX to the customer's network and you try to PING DNS server for example, on our PIX, I have following error:

  305006: failed to create of portmap for domestic 50 CBC protocol translation: dst outside:194.x.x.x 10.10.1.x

  194.x.x.x is our customer s address IP PIX

  I understand that somewhere access list is missing, but I can not understand.

  Of course, I can configure VPN site to site, but we have few customers and take us over their servers, so it'd just connect behind PIX VPN and client connection s server, instead of the first dial-in and then establish a VPN connection.

  Can you please help me?

  Thank you in advan

  The following is extracted from ASK THE DISCUSSION FORUM of EXPERTS with Glenn Fullage of Cisco.

  I've cut and pasted here for you to read, I think that the problem mentioned below:

  Question:

  Hi Glenn,.

  Following is possible?

  I have the vpn client on my PC, my LAN is protected by a pix. I can launch the vpn client to connect to remote pix. Authenticates the vpn client and the remote pix makes my PC with the assigned ip appropriate to its pool of ip address.

  The problem that I am facing is that I can not anything across the pix remote ping from my PC which is behind my pix. Can you please guide me what I have to do to make this work, if it is possible?

  My PC has a static ip address assigned with the default gateway appropriate pointing to my s pix inside interface.

  Thank you very much for any help provided in advance.

  Response from Glenn:

  First of all, make sure that the VPN connection works correctly when the remote PC is NOT behind a PIX. If that works fine, but then breaks when put behind a PIX, it is probably that the PIX is PAT, which usually breaks IPSec. Add the following command on your PIX VPN client is behind:

  fixup protocol esp-ike

  See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/df.htm#wp1067379 for more details.

  If it still has issues, you can turn on NAT - T on the remote PIX that ends the VPN, the client and the remote PIX must encapsulate then all IPSec in UDP packets that your PIX will be able to PA correctly. Add the following command on the remote PIX:

  ISAKMP nat-traversal

  See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/gl.htm#wp1027312 for more details.

  NAT - T is a standard for the encapsulation of the UDP packets inot IETF IPSec packets.

  ESP IPSec (Protocol that use your encrypted data packets) is an IP Protocol, it is located just above IP, rather than being a TCP or UDP protocol. For this reason, it has no TCP/UDP port number.

  A lot of features that make the translation of address of Port (PAT) rely on a single to PAT TCP/UDP source port number ' ing. Because all traffic is PAT would be at the same source address, must be certain uniqueness to each of its sessions, and most devices use the port number TCP/UDP source for this. Because IPSec doesn't have one, many features PAT fail to PAT it properly or at all, and the data transfer fails.

  NAT - T is enabled on both devices of the range, they will determine during the construction of the tunnel there is a PAT/NAT device between them, and if they detect that there is, they automatically encapsulate every IPSec packets in UDP packets with a port number of 4500. Because there is now a port number, PAT devices are able to PAT it correctly and the traffic goes normally.

  Hope that helps.

• How backup VPN configuration between two universities?

  Hello, I am a student of the Greece and I have a graduation project to configure Backup VPN between two universities. Principal of communication made with leased lines. I study a lot, but now that it's time for implementation I have some thoughts:

  -What hardware and software IOS do I need? Cisco 1841 it is ok for A & D routers?

  -Use GRE IPSec transport mode or IPsec Tunnel mode?

  -What will be the failover mechanism for switching traffic lines leased to IP VPN Backup and opposite? A teacher told me something about the Interface Prioritys. I read somewhere that this is done with the such as EIGRP routing protocol. who was right the Professor or the book?  :-D

  -In the same place, they have Firewall and NAT, I need to do any action for this?

  The attached file contains topology I want to implement

  'My' talk site 1

  2 a Central Site

  E communicates with A, but no traffic is to A of E with normal circumstances. Subnet on E access Internet through F, then press D.    VPN will be implemented on the LAN but the specific source E traffic will pass through the Backdoor VPN (I think that the solution to this is ACL on the router). They have no routing protocol in 'my' site A directly connected routers and the default routes.

  How imlement this?

  I think the first thing to do is A to D connectivity

  I will try to do this to tracers package first, but how can ' I imitate the SP network?

  I need help I can get!

  Hi John,.

  In our scenario, given that our main connection is a direct leased line between E and F, so I guess there is no other network between the two routers. In this case we do not need to configure SLA monitoring or any interface a priority. We can simply enter two default routes:

  IP route

  IP route 254

  In this scenario, if the leased line interface goes down, the second default route is used and the traffic should be routed by A router.

  SLA monitoring monitors connection (using the ping tests) by one of the interfaces of the router, and when we are not able to ping from one server (specified in the configuration of the SLA) through the interface, then we change the default track to track traffic through some other interface.

  So, in your scenario, we can monitor the connection between E and F, and when the link goes down, we can change the default route to point a.

  This is useful in the scenario where we have another ISP connection as our primary connection.

  Here is a link on how to configure SLA monitoring on the router:

  http://www.Cisco.com/en/us/docs/iOS/12_4/ip_sla/configuration/guide/hsicmp.html

  After you have configured the SLA followed by using the link above, you can bind it to the default route by using the following command line:

  track road IP / / default main route

  IP route 255 / / default route with a metric of higer that comes into play when the main default route goes down

  In addition, the sample configuration that you give in the doc is almost correct, defined transformation is missing just a hashing algorithm. Here is a link with an example for a tunnel from lan-to-lan between two routers:

• is it possible to establish a direct connection between two computers, one running on windows xp sp2 and other running on windows xp sp3?

  Hello
  I connected two computers, one running on windows xp sp2 and others running on windows xp sp3 via com using RS232 port via link Modem DFM-562E ++.
  I am able to dial numbers from a PC successfully.
  But when I do a direct link between them (one as a host, the other guest) through the com port, I get error 777.
  Is this because the two PC's using different service packs?
  Help, please.
  Thank you & best regards
  Ravi

  It is not the service pack - although you should have installed sp3 now.

  Your message is not clear: have you been able to connect successfully computers using your modem D-Link?  How did you do that?  Will there be a modem in the second computer?

  What cable are you using to establish a direct connection between the com ports on both computers?  If you have purchased this cable online, please provide a link to the site where you bought it.

  Please describe the physical connection between the two computers.  For example, this is how you connect to the Internet by dial-up services:

  computer 1-{(9 broches) RS-232 serial port}-{RS-232 cable supplied with the modem}-{modem}-{phone cord (RJ-11 modular plugs at each end)}-{telephone wall jack}

• PIX firewall problem

  I have two servers, one in pix inside and the other in the demilitarized zone. I wanted to set them up so that they can communicate with routers and switches

  Located outside the pix firewall.

  My inner Server works fine, able to go Internet and able to comminicate with all devices located outside the Pix Firewall. Here is reference configuration

  of insideserver.

  inside_acl list extended access permit ip host 172.28.32.50 all

  But my DMZ server does not work. However, I made the same configuration with respect to the server on the inside. Not able to communicate with outside DMZ server

  If I create a static entry for your DMZ SNMP server.

  static (edn, external) 172.28.92.72 172.28.92.72 netmask 255.255.255.255

  He starts to communicate with external devices, but stops Internet run on this server. same configuration

  works with the server on the inside, but not with dmz server.

  NAT (inside) 3 172.28.32.0 255.255.255.0

  NAT (dmz) 3 172.28.92.0 255.255.255.0

  Global interface 3 (external)

  Your static entry is bypassing your nat (dmz) 3 entry. You can do NAT exemption instead, as you do to your home

  1. remove the static entry (followed by clear xlate)

  Add - nat 0 access-list sheep (dmz)

  I suggest to use two acl different sheep, one for each interface.

  Ex: nonat_inside

• Data connection between two applications

  Hello world

  Is there a way to open a connection of type 'stream' between two applications without using the file system?  Writing on file seems too gross.  Surely someone does this!

  What I found so far:

  Object 'Event' does not seem to do... DOM seems to be communication within an application or suite.

  "Socket" seems to be ruled out by security, but no official word on this issue...

  "Then" explicitly says that only one application can access a serial port at any time...

  Class interface 'Connection' seems to have many children (taking one) but all seem to be dead ends.

  Anyone?

  Thank you

  DD

  I suggest using a global event. You can attach an object to the event and look to the other application.

  See the documentation for the API of ApplicationManager.postGlobalEvent () and the GlobalEventListener interface.

  Hi Zeff,

  You can make Windows 7 the main computer for internet connection and then host the Windows XP computer.

  For more information, see the article:

  Start here to set up a home network in Windows 7

  Networking of computers running different versions of Windows

  With respect to the equipment as a router, hub, NIC depend on the connection (wired or wireless) you want to use. You can also check with the ISP (Internet Service Provider) for more information.

  For more information, see the articles:

  What do I need to connect to the Internet?

  Setting up a network home

  Wired and wireless connections have great benefits, but they have also some disadvantages.

  Wired connection:

  > Faster and more robust than wireless connections but not so flexible when positioning of computers and devices because you must be connected to your Super Hub with an Ethernet cable.

  > Safer than wireless connections, but not so convenient for users of laptops and other mobile devices.

  WiFi connection:

  > Wireless! If you can connect when you want. However performance may be affected by walls, electric interference etc.

  > Ideal for users of laptops and other mobile devices, you can connect devices more but slower than wired connections

  > Very safe when used with higher level (WPA) encryption. You can connect your smart phone to your network wirelessly for faster browsing.

  However, unauthorized users could try to use your connection (which explains why security is so important).

  There are two types of IP addresses. external and internal. Both computers have the same external IP address but separate internal IP addresses. Each device in your network will have its own (internal) IP address. The external IP address, who sees the Internet is actually assigned to your router.

  Hope the helps of information. Let us know if you need help with Windows related issues. We will be happy to help you.

• How to stop the connectivity between two computers that use the same IP address... ?

  Today, I managed to connect two computers with the same IP address. But now it is to be feared. for example, a person can access my computers using my IP and MAC address. So now, how can I stop the connectivity between these two computers. should what setting I use to stop.

  Tahnks.

  Hello

  1 have. what measures you taken to connect 2 computers with the same IP address?

  2. How are the 2 computers connected?

  3. how exactly you want to stop the connectivity between 2 computers?

  I want to tell you that 2 computers on the same network cannot have the same address. Each machine must have a unique address to identify it. A private network, as a home network connected to the internet, can be connected to a router to connect to the network, will have only 1 address, public IP address.

  In addition, if we know the IP address of a computer along the user ID and password, we can access the computer/shared files.

   
  If you are referring to the change of the IP address of the two computers, you can follow these steps and check.
   
  a. network connections open. Click the Start button, and then click Control Panel. In the search box, type 'adapter' and then, under center network and sharing, click view network connections.
  b. right click on the connection you want to change. Click on properties. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  c. click on the network tab. Under this connection uses the following items, click Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), and then click the properties button. To specify your IP for IPv4, click on use the following IP address, and then, at the address IP, subnet mask, and gateway boxes by default, type IP address settings.
   
  A typical IPv4 address looks like 192.168.0.2; a typical subnet mask is 255.255.255.0. The default gateway is usually the address of your router.
  For example, IP address: 192.168.0.2 by 192.168.0.12 (for computers)
  Subnet mask: 255.255.255.0
  DNS: 192.168.0.1

• Connectivity between two piles of Dell 2048

  Hi guys, I'm very new to the configuration of the switches. We have a small office and just implement a new data room. We have 4 switches of POE Dell 2048 x stacked for VOIP and PCs phones and 2 x Dell 2048 switches stacked to our servers. I have 4 x 10 gb twinax cables to connect the two heaps as in the pic below:

  

  What is the best way to implement these four connections? I tried to do a SHIFT of four ports in each stack, and it seemed to fall some ping until I disabled STP for the LAG group. I'm a little worried about turning off STP however. These are the only switches that are on the network. Any ideas on what the best config for this would be appreciated. Sorry, as I said I am quite new to this.

  Thanks, Dave

  Hi guys,.

  Just to wrap this I configured LACP on the mentioned LAG today and now, she purrs like a kitten.

  See you soon,.
