Client VPN ASA5505 problem

Similar Questions

• 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:

• With tunnel VPN ASA5505 problem

  The business needs is for a VLAN again on site to go directly back to an internet service to site B.

  Site A and B are connected by a service of WES MB 100.

  A site is a site of campus with about 25 switches. Him become VLAN on the site is for the engineer access only, so they can access their companys remote access service. This VLAN must stay back so there is very little potential of a trade-off on the live network.

  The solution that I just put in place is to place an ASA5505 as the dhcp server for him VLAN become to Site A. All clients on that VLAN become get a 192.168.100.x address. The external interface on the ASA5505 to Site A is put on the live network to allow a site VPN tunnel to be put in place between the ASA5505 and the Internet - an another ASA5505 firewall

  The Site A ASA5505 was put in place with inside and outside interfaces with the same level of security. 192.168.100.x subnet is exempt from NAT. Traffic is configured to transmit via the interfaces with the same level of security and the tunnel of L2L is coming.

  But I can not all connectivity to the internet from any host on the 192.168.100.x VLAN.

  This is made more complex because the external interfaces on both of the ASA are the corporate network...

  The default route to the Site B ASA5505 is 87.xx.xx.1, the ISP router.

  The Site B ASA5505 connects directly to the ISP router.

  There are some parts of the configuration that you have published to that surprise me, such as the assignment of the default route on the inside interface. But these things are not at the heart of your problem. I agree that the core of your problem is probably the sheep access list. If I understand your needs, what you need is 192.168.100.0 is not translated by going to meets B, and is translated by going to the Internet. But your translation says access list never 192.168.100.0 since your access list as another destination:

  access-list no. - nat extended ip 192.168.100.0 allow 255.255.255.0 any

  My suggestion is to rewrite this access list and change the destination of the 'all' to be addresses behind B (LAN to B).

• VPN-ASA5505 problem

  Hi all

  I inherited this VPN and get slowly upward. At least users can connect to it now!  I had a few problems. Users can connect to the VPN, but cannot ping or access shared files on the server (192.168.2.3), but the VPN users must be able to make full use of the network.

  I removed the NAT rule.

  #no nat (inside) 1 0.0.0.0 0.0.0.0)

  And after removing that, VPN users have been able to navigate and access to internal resources. However, users in the office now had no internet. I went and added the rule of return and returned internet.

  Believe it is related to the split tunneling, what can I do to activate full VPN access and still have internet at Headquarters?

• ProBook 650 1: Problems with W10 upgrade - Client VPN in my notebook?

  Hello

  I upgraded my laptop to Windows 10 but, like many people, I encountered some problems with the Broadcom 802.11 wi - fi adapter. I read a lot of discussion about it and I decide to yestarday to roll back to Windows 7 in order to do a clean update by ISO and unisntall VPN. I read that Cisco VPN Client is the problem when upgrading to W10... but I'm not sure I have the Cisco Client in my notebook.
  You help me find a software which VPN I have in my book?
  I run Microsoft Fixit and found out that I have:
  Cisco PEAP
  Cisco LEAP
  Cisco EAP-FAST

  Is this software VPN? Or not?

  After having updated Broadcom driver on Windows 10 WiFi worked well, but I still had an error message ' Broadcom 802.11 network adapter wi - fi doesn't work "whenever I turned on the laptop.
  In addition, it was impossible on W10 to open the Broadcom Wireless Tool (Control Panel) software, I always get an error message.

  Should I unistall Cisco software?

  See you soon,.

• Connection with the client VPN for RV110W problem

  Hi guys: I just installed a RV110W router to my small business and I try to connect via VPN from home client.  I was unable to do so, no matter what I try.  Relevant information:

  1. I can connect to the router via remote very well management, so I know that the router is accessible from the Net.

  2. internal address of the router: 10.81.208.1

  3. active PPTP.  PPTP server IP address: 10.0.0.1

  4 IP addresses for PPTP clients: 10.0.0.10 - 14

  5. two VPN clients added - one with PPTP, with the QuickVPN Protocol Protocol.  Both are enabled (and Yes, I triple checked passwords)

  6 encryption MPPE and Netbios active.

  7 IPSec, PPTP and L2TP all active gateways.

  8 VPN client: 1.4.1.2

  9. computer: laptop running Windows 7 family (64-bit), with the firewall Windows is activated.

  10 home network: 192.168.2.196

  It is causing to tear my hair out.  What Miss me?

  Shannon

  Hi Shannon,

  I am pleased to see that you're progress.

  Shannon Rotz wrote:
  I changed the RM port to 443.  Unfortunately, now I can't connect to the router via browser, either by remote management or from the local network - I get the usual "page cannot be displayed".  How do I get back into the router configuration GUI?
  

  You should be able to reach the GUI by typing https://192.168.1.1(assuming that you have not changed the default IP address) normally once you replace http (port 80) with https (port 443) the internal router web server automatically will redirect you to the https page if you type http. Open your command prompt and try to do a ping of the IP address of the router to ensure that it still meets this address

  With regards to the VPN client:   Up until I changed the port, the same error message kept coming up, i.e. "Unable to establish connection" (or something like that), with a list of possible reasons why it couldn't connect. Now the message has changed - I'm getting "Server's certificate doesn't exist on your local computer".  If I continue trying to connect, then it says "Activating Policy", followed by "Verifying Network", then "The remote gateway is not responding.  Do you want to wait?"  This is definitely progress, since I never got this far before.

  You are a quarter inch offline. If you look at the log.txt in C:\Program Cisco Small Business\QuickVPN Client, in my view, you will see "Failed to ping router remote VPN! This means that your PC is blocking the ping to the router response. Usually, if you look at this point the status of Client VPN in the router (first of all need to remote management) you will see that your user status is "connected." If the router thinks that the connection is established, but the PC does not work. You might want to try another PC at this stage to verify that it is indeed a problem with your PC. This problem is usually caused by the 3rd party software antivirus/firewall blocking the ping response. Microsoft Security Essentials can do this as well, so if you turn it off. If you do not have another PC to test from, call Cisco Small Business Support and ask a technician, try to connect to the lab. You can find the number to call here

  On an impulse, I tried setting up a Windows VPN connection, i.e. created a new VPN connection in Network and Sharing Center, using a PPTP client ID that I had created.  That connection actually worked, except for one problem:  I can't see the remote network.  If I could solve that problem, I'll just tell the other clients to use a Windows connection rather than QuickVPN.
  

  Good thought. If you do not see the remote devices, make sure that they do not block VPN connections. (Windows or third-party firewall, antivirus, antispyware) With a connection, PPTP or QuickVPN, you should be able to go to run, type the IP address of the device that you want to connect to (i.e. \\192.168.1.101 ) and see the list of shared folders. After the PPTP connection is established, try to ping the address LAN IP of the router. If it is successful, try to ping a LAN device such as a network printer or a PC. Again, PCs may block ping requests if they have a firewall running watch so for this.

  Answer please if you have any questions.

• 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.

• Client VPN will travel not connected via 877w

  Hello

  I've implemented a Cisco 877w and it works very well for web access

  Client VPN on my laptop connects via the 877w and authenticates on my remote work ASA5510 firewall.

  Problem is after you connect to the ASA, I can not connect anything internally work network (10.0.0.0/24), ping, etc. RDP is back with no answer.

  I've attached the config, can someone tell me what I am missing, might access a list?

  Thanks for your help

  Chris

  This router is made PAT/NAT, Ipsec blocking.

  Activate Nat on the ASA course remote.

  ISAKMP nat - t or crypto isakmp nat - t

• Client VPN Cisco router Cisco, MSW CA + certificates

  Dear Sirs,
  Let me approach you on the following problem.

  I wanted to use a secure between the Cisco VPN client connection
  (Windows XP) and Cisco 2821 with certificate-based authentication.
  I used the Microsoft certification authority (Windows 2003 server).
  Cisco VPN client used eTokenPRO Aladdin as a certificate store.

  Certificate of MSW CA registration and implementation in eToken ran OK
  Customer VPN Cisco doesn't have a problem with the cooperation of eToken.
  Certificate of registration of Cisco2821 MSW ca ran okay too.

  Cisco 2821 configuration is standard. IOS version 12.4 (6).

  Attempt to connect to the client VPN Cisco on Cisco 2821 was
  last update of the error messages:

  ISAKMP: (1020): cannot get router cert or routerdoes do not have a cert: had to find DN!

  Is there some refence where is possible to find some information on
  This problem? There is someone who knows how to understand these mistakes?
  Thank you very much for your help.

  Hey guys, it's weird that the router is not find cert after IKE is the cert and validates, it is certainly not reason, but I would go ahead and set up the mapping of certificate on this router to force the client to associate with Group of IKE, for that matter, that you need to change your config a bit for use iskamp profiles :

• Client VPN not open or connect

  Hello

  I'm currently running Client VPN 5.0.07.0440 on a Windows 7 Pro HP TouchSmart. The .pcf file is that the same iI uses the same network on many other om of machines.  When I double click the icon, the window opens, but when I double click on the login entry, the dialog box shows 'connection to the gateway security to xxx.xxx.xxx.xxx for a few seconds and then says no 'connected'.  I can't even login screen I can normally. This is a new mode of computer. All updates are downloaded for windows.

  I uninstalled the client and re-installed it re-boot after each step. I have ping for the address and had no problems. Avast, Malwarebytes as on other machines running. No other security software. My VPN is enabled in my network connections.

  Here is my log file:

  I know the names and passwords are correct, as they were copied from work files.

  Hope this is posted in the right group.

  Never had this problem after a lot of machines. Any help would be greatly appreciated.

  Thank you

  Since you get the message 'can be configured with password invalid group", perhaps your FCP file has been corrupted.

  I would recommend that you compare the profile pcf file (stored in "C:\Program Files (x 86) \Cisco Client\Profiles") on the machine of non-working with a working configuration.

  They can be viewed in a text editor or with a comparison (like the freeware ExamDiff) tool. The hashes from encrypted password Group (string in file preceded by "enc_GroupPwd =") must match.

• Causing disconnections Windows LAN Client VPN service

  Hello

  I have a 4.8.01.0300 client installed on a machine WinXP SP2, speaking with a VPN3000 concentrator and its working very well through the VPN. My client complained however that when you use the machines with the client installed on their local network, they get notice of ongoing disconnection of their offline files and synchronize the failures. If manually stop us the service of cvpnd.exe, the problem goes away. Affecting the service manual and start the service instantly back again the issue.

  Does anyone have this seen before or know a fix?

  Thank you

  Hello

  Please check if the dynamic firewall is enabled or disabled. Please make sure that it is disabled. To check, the client VPN application and goto startup options. You should see Stateful firewall. It must be unchecked.

• Client VPN PIX a weird question

  Hello

  I have a pix501 that several clients are VPNing in. The problem is that when they open their clients (ver. 4.602.0011), there is a default name in the user name text field. Each time, they try VPN in they must remove the name and put their own name in. I tried this on an asa and I can't reproduce. What Miss me?

  Thanks in advance!

  Hello

  The issue could be with the file .pcf for connection of PIX including the 'User name' populated field. Go to the installation directory of the client VPN on your PC.

  Then go to the folder "Profiles" and select the corresponding to the PIX .pcf file. Once you open that, you will find the 'User name' populated field. Delete the value where theusername and then try to connect.

  Let me know if it helps!

  Kind regards
