  Hello.

  Concentrators are very friendly units (IMHO) to VPN with NAT and VPN.

  You build an acl defined traffic over the vpn (110) based on the nat wouldn't

  You create an acl to set what is NAT had (111) and create a NAT statement accordingly

  Here is an example configuration.

• VPN configuration blocking Internet connectivity

  I own an iPhone6 (bought in November 14 and another iPad4 (bought in early 2014) - I face a problem even in both devices.)

  Whenever I'm trying to be devices connecting to the Internet (this either through Mobile or wireless data, I have to take concrete steps to start-up the VPN setting without which the device connect to the Internet. However sometimes (although not very often) the VPN configuration gets turned on by itself without manual intervention (on start-up or mobile data or WiFi on the device). So there is always some delay time in the connection to the Internet whenever I want to use the device.

  I would be grateful for suggestions from the community in order to overcome the problem.

  You have installed VPN software or you have configured in your VPN settings? If you have a VPN configuration, then check its configuration. If you do not have a VPN configuration or a VPN software installed, then the VPN switch in settings should not illuminate.

• OfficeJet Pro 8600 Plus: PC stopped communicating with wireless Officejet Pro 8600 more

  My HP printer has been connected to my PC via my home wireless network and work without problem, for 18 months.  A few weeks ago the printer stop appearing in the printer dialog box when I went to print a document.  The printer continues to operate wireless for all my mobile devices without problem.

  I went through all the HP process and tools for troubleshooting, downloaded and installed all updates, nothing helps.  I uninstalled my PC off and now it will not reinstall.  The installation process see the printer on the network, but when I try to install it it said "cannot be installed on the network" and it goes no further. I lost hours and hours trying to get to the bottom of it, nothing helps.

  What is the problem?

  Hi @Layli,

  Welcome to the HP Forums!

  I noticed that your PC has stopped communicating with your HP Officejet Pro 8600 wireless connection more. I'm sorry to hear that, but happy to help!

  Out of curiosity, what happens if you install the printer using the USB method wireless configuration? Check out this guide, your wireless printerand select Configuration USB wireless.

  Also, if this does not work, able to install the printer are you using a USB connection? In this way, we can see if the problem could be the connection itself or not.

  You see error messages on the control panel of the printer at all?

  Thanks for posting and hope to hear from you soon!

• Client VPN connectivity problems

  I use the cisco VPN client to connect to our network, located behind a 515E. The client is authenticated and gets an ip address but cannot ping or connect with one of the hosts. The connection is to a network of customers that is also behind a 515E. I have successfully connected using the same policy to other places and have had no problem. What confuses me, is that we have used to have a Netscreen firewall before and he had a netscreen vpn client which connected since their network with a problem. Is that something they need for their firewall so that we can get through the traffic?

  Try to turn on NAT - T on your pix, by setting up:

  ISAKMP nat-traversal 20

  and configure the client vpn accordingly:

  Hello

  It is the router that ends the VPN tunnel? (I don't see the VPN configuration).

  Since you can't use your real address LAN, you need to NAT before you send the traffic through the tunnel.

  First, you apply the NAT rule to translate 192.168.1.0/24 to 10.240.86.33 when you go to 164.2.107.56

  NAT 192.168.1.0 ip access list allow 0.0.0.255 host 164.2.107.56

  NAT route map

  corresponds to the IP NAT

  IP pool local VPNPool 10.240.86.33 10.240.86.33

  IP nat inside source overload map route NAT pool VPNPool

  Next, you create the ACL list for interesting traffic to address coordinated at the address of the site to another

  VPN ip host 10.240.86.33 access list permit 164.2.107.56

  We will see the results.

• ASA 5510 IPSEC VPN connection problem

  Hello

  We have an ASA 5510 (ASA version 8.0) of remote access VPN configured and works most of the time, but there is a problem when you have more than one client that connects to the same office remotely.  When the first VPN client is connected to the remote desktop, everything works fine, but when the second client connects to the VPN, it connects fine but do not get any traffice return to customer.  I can see under monitor-> statistical VPN-> Sessions-> remote access-> Rx Bytes is 0. Both connections are from the same public IP address of the remote desktop.  I changed some settings on NAT - T and a few other things, but without success.

  Could someone help me please how to fix this?

  Thank you very much.

  Make sure that customers use because that probably her you're not. (default value is NAT - T).

• ASA 5505 VPN Ping problems

  Hi all

  First of all, I apologize if this is something that I can google. My knowledge of the administration of the network is all self-taught, so if there is a guide that I missed please point me in the right direction, it is often difficult to Google the terms for troubleshooting when your jargon is not the height.

  The main problem is that when ping devices internal when you are connected to the results are very inconsistent.

  Ping 192.168.15.102 with 32 bytes of data:

  Reply from 192.168.15.102: bytes = 32 time = 112ms TTL = 128

  Request timed out.

  Request timed out.

  Request timed out.

  We have implemented an IPSec VPN connection to a remote Cisco ASA 5505. There is no connection problems, connection seems constant, etc. good packages. At this stage, I can only assume I have configuration problems, but I was watching this while if long and pair with my inexperience configuration of these settings I have no idea where to start. My first impressions are that LAN devices I'm ping do not send their response back or the ASA does not know how to route packets back?

  Here is a dump of the configuration:

  Hi Graham,

  My first question is do you have a site to site VPN and VPN remote access client.

  After checking your configuration, I see you don't have any Site to SIte VPN configuration, so I'm assuming you ara facing issue with the VPN client.

  And if I understand you are able to connect VPN client, but you not able to access internal resources properly.

  I recommend tey and make the following changes.

  First remove the following configuration:

  NAT (inside) 0 inside_nat0_outbound_1 list of outdoor access

  NAT (inside) 1 192.168.15.192 255.255.255.192

  You don't need the 1st one and I do not understand the reason for the second

  Second, one is your pool IP subnet (192.168.15.200 - 192.168.15.250) and I don't know why you added this NAT.

  If possible change your subnet pool all together because we do not recommend to use th ip POOL that is similar to your local network.

  Try the changes described above and let me know in case if you have any problem.

  Thank you

• Computor stop communicating with the wireless printer

  My computor Asus seems to have stopped communicating with my HP printer / scanner today, when I run convenience store he tell me the printer is offline. We changed anything. He has worked in the last two years very well.

  Hello

  What is the model number of the HP printer?

  You can try the following and see if they help.

  Method 1: Try to set the printer online.

  a. open the start menu and click on the "devices and printers". This will open a window with a list of the printers currently installed on your computer. Right-click on the printer and select "Use printer online".

  b. clear all print jobs. Double-click on the printer, then go to the Menu "printer" and select "Cancel all Documents." It could be a stuck print job that would cause the printer go offline. Try once more to put the printer online and try to print a test page.

  c. turn the printer off and then on again. Check if the printer is blocked. Check all the network connections to make sure that none are loose.

  Method 2: refer to this link and check if it helps .

• Site to site VPN PIX problem

  Hello, I have a problem when I need to implement a VPN IPSEC with ESP and key pré-partagées between two sites...

  The two sites are using PIX Firewall (Version 6.3 (3) to complete the VPN)

  I'm ok with the VPN configuration and have tested & it works

  the problem is that the PIX at the remote end must be behind a DSL router that is PATting for the PIX

  This is because the ISP can only assign a public IP address and that is to their adsl router and I don't have a public IP address that I can directly attribute to the PIX...

  is there some way I can put the second PIX address of outside interface on a private and still make a VPN connection with it?

  LAN1---PIX1---INTERNET---ADSLROUTER---PIX2---LAN2

  Thank you very much

  You will not be able to specify PIX2 private address in the config of PIX1, cause your ESP packets never get there through the Internet.

  The only way it would work is to configure the port on the ADSL router mappings, which maps the specific packages through to the PIX interface address. Config of PIX1 would then point to the ADSL router interface address.

  Or you can talk to the ISP and try and get another IP address, and then create a mapping on the ADSL router and everything for this grace IP address to map to the PIX.

  Or you could configure PPPoE directly on the PIX and get rid of the ADSL router in total. See here (http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/config/pixclnt.htm#wp1072346) for more details.
