• Cisco vpn client to connect but can not access to the internal network

  Hi all

  I have a VPN configured on cisco 5540. My vpn was working fine, but suddenly there is a question that the cisco vpn client to connect but can not access to the internal network

  Any help would be much appreciated.

  Hi Samir,

  I suggest that you go to the ASA and check the configuration to make sure that it complies with the requirements according to the reference below link:

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00805734ae.shtml

  (The link above includes split tunneling, but this is just an option.

  Please paste the output of "sh cry ipsec his" here so that we can check if phase 2 is properly trained. I would say as you go to IPSEC vpn client on your PC and check increment in packets sent and received in the window 'status '.

  Let me know if this can help,

  See you soon,.

• IPSec on the Client TCP connections via USB

  We have a problem (and I noticed that several other people here are as well) to our users of broadband remote is not not able to connect. We just recently started getting complaints from users at home XP they were getting errors while trying to connect to the hub.

  To begin troubleshooting we moved our hub 3015 outside our firewall temporarily. Users were still unable to connect. After some additional troubleshooting, we were able to successfully reproduce this problem by simply changing the VPN client to users of IPsec over TCP to IPsec over UDP.

  Then, we tried to identify why she passed to some customers, but not all. In the end, the only thing we could find really different was that customers who have a USB port to connect to the network instead of a correct Ethernet port cannot connect via IPSec over TCP. We have tested and verified on several operating systems, including Windows 2000, XP Home and XP PRO. We have also tested and verified with multiple VPN Clients including 3.5.1 and 3.6.3b.

  The end result is that all case users who use a type USB connection cannot connect via IPSec over TCP. All users who connect through a correct Ethernet adapter are able to connect via another method.

  Our problem is that we cannot run UDP connections behind our firewall without conversion on NAT. We send a client preconfigured to our users which forces to use tcp port udp by default 10000 10000 verses. We do this for several reasons, but the most important of them is our firewall will not redirect sessions IPSec UDP, IPSec TCP sessions only.

  Leaving the VPN concentrator outside the firewall and exposed is not an option. So, I find myself with say to all my users USB that is the only way that they can connect to install an Ethernet card, which ultimately is not really much of an option considering expenditure and technical knowledge necessary to pull it off the coast with hundreds of individuals it just will not fly.

  So, this brings me to this forum. Before I open a TAC case I hear experts to try to determine as closely as possible, if this is a problem of Microsoft or Cisco VPN client. I have my suspicions that this is owned by Microsoft, but I can't prove anything yet. Does anyone else have an idea on this? Please, I invite everyone to test this out and let us know what you find. If you would like more details on the methodology please let me know and I would be happy to provide it. I think it is potentially a huge problem only by the number of complaints I've seen in this forum. My supervisor thinks I smoking something when I try to explain this to him. All he can say is "if it was really a problem, more people would certainly also, and you would have heard about it now, it must be in your configuration." GO FIX"(does all this sound familiar?)

  I appreciate all of the comments that everyone is willing to give. I think that if we as a community get together on this we can find a solution.

  Thanks for your time!

  It is a bug, use the bugtool kit to see bug CSCdv00229.

• VPN client - multiple connection possibilities?

  Hi people,

  My basic question is, Cisco VPN Client allows two simultaneous VPN connections at the same time?

  I would like to implement the following:

  Customer user (remote access VPN via Internet)--> Head Office c/o ASA 5520 pair--> (VPN remote access via Internet)--> pair of Branch Office ASA 5510 S + a/s

  For example, to access the Branch Office system, the user must:

  1. connect to the peer of Head Office ASA via Cisco VPN Client (the user/password authentication)

  Head Office ASA peer gives an 172.16.1.x private IP address and is configured to route all requests for public office ASA IP through its own public IP address.

  2. once Head Office VPN is established, the user establishes a SECOND VPN tunnel of the Cisco VPN client (user/password and focused on the cert auth)

  I.e. branch sees the VPN connection try from the public IP address of Headquarters and therefore allows the VPN through the ACL traffic and allows the continuation of the VPN negotiations as usual.  Customer is given another IP address private, 192.168.10.x.

  Basically, I need to limit the remote access VPN branch to make it only accessible from Headquarters public IP address, no public IP address of the user (and therefore the entire internet).

  
  

  I know this is an unusual configuration, and some will say on the sensitivity of security to allow two simultaneous VPN connections.  These are the two networks of trust, strict ACL would be at stake and there is a long history behind this requirement...

  Thanks in advance!

  Alistair,

  You can limit the access of VPN connections to branch by blocking connections on UDP ports 500, 4500 UDP and ESP and allowing him only from your home office. In this way, only the explicitly authorized public IP address of your home office would be able to connect to your remote sites by using an IPSec tunnel.

  Now, on the second tunnel I don't think it's possible. As far I am aware you cannot have two connections to VPN at the same time of the same customer. The VPN will not let you do, it's mainly because when you have a VPN Client the VPN map session comes up and you can only one card virtual VPN.

  Because I don't think it is possible I would advice to try something like this:

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/products_configuration_example09186a008046f307.shtml

  Could provide you the connectivity that you are looking for without needing a second tunnel VPN from the client side.

  I hope this helps.

• VPN client, lost connection

  Hello

  I pix506e here... and vpn clients connected.

  But suddenly lost connection vpn client 40 minutes and then try to reconnect again but fail. If the vpn client restarts their pc/notebook...yes it can connected to vpn again... but the interruption of the connection again... then restart... and so on... What is the cause of this problem?

  Thanks for the help

  Tonny

  All remote VPN clients are having the same problem or is it limited to just a few. If the problem is seen with only a few, it is quiet possible that the problem is not with the PIX of the customer. In addition, the DPO is enabled or not. DPD will cause tips to know an IPSec connection over, where the SAs flusing, allowing new being negotiate quickly.

• 506th PIX and VPN client - multiple connections connections

  I have a PIX of the 506th (6.2) w/3DES license and 3.6.3 VPN client software. I'm only using group user name and password to authenticate. The first user login works fine. When the second user connects, the first is finished and the second works very well. The product turned on States I should be able to have 25 simultaneous connections or site to site or customer.

  Any help will be greatly appreciated, Kyle

  Are these two users on the same site, behind a device that makes PAT? If so, then this device is causing the problem, not the PIX. The device is unable to correctly translate the IPsec packets. Unfortunately nothing you can do about it on the PIX, although the next version of the software (6.3 to your calendar of March) will have NAT - T support (which the client currently supports). Once that support NAT - T both ends, they'll be able to say that there's a PAT instrument between the two and they will automatically encapsulate everything in the UDP packets, which your PAT instrument will be able to translate correctly.

• Binds two ISP ASA to remote VPN Client to connect to instead of creating two profiles on the remote client

  Hello

  just a quick,

  TOPOLOGY

  ASA isps1 - 197.1.1.1 - outside

  ASA ISP2 - 196.1.1.1 - backup

  LAN IP - 192.168.202.100 - inside

  I have configured Tunnel on the interfaces (external and backup), but is to link both legs public to serve a thare as redundancy for vpn users and users of the vpn tunnel leave pointing inside IP whenever they want to establish vpn sssion, we want it to be one, so if an interface fails vpn users will not know , but he will try the second for the connection. instead of creating the profile for the two outside of the leg on the vpn client.

  is this possible?

  Hi Rammany.

  In your case, you have only an ASA that connects with 2 ISP in another segment IP... 196.x.x.x (Link1) & 197.x.x.x (Link2). What your condition is you want to have the VPN client who must be consulted with backup. If 196.x.x.x link fails, it should automatically take 197.x.x.x link. That too we should not have the config set in the VPN client backup server. You don have the possibility of having standby active also in asa single.

  I think n so it will work with your current design.

  This option is if your VPN client supports host name resolution (DNS). You can have the VPN created for both the public IP address share the same host name keeping the bond as the primary address 1 and 2 a secondary address. It will work alone.

  Hope someother experts in our forum can help you with that.

  Hello

  1 - Please run these commands:

  "crypto isakmp nat-traversal 30.

  The main issue here is that you have two roads floating and outside it has a better than backup metric, that's why I added the command 'reverse-road '.

  Please let me know.

• RV082 VPN Client can connect only for 6 minutes

  Hello

  I have a RV082 with firmware 1.3.98 - tm.

  The problem I have is that a Client with Windows XP SP3 can connect only for 6 minutes exactly.

  In addition, a windows appears on the client saying that the remote system is not respoding and asking to wait or not.

  We have also applied fix for Windows XP described here:

• IOS router VPN Client (easy VPN) IPsec with Anyconnect

  Hello

  I would like to set up my router IOS IPsec VPN Client and connect with any connect.
  Is it possible to configure an IPSec and SSL VPN Client on IOS router? I use for example a 1841.

  It would be perfect to give the user the choice of SSL or IPSec protocol. And the user needs that the Anyconnect Client.

  I think it's possible with a Cisco ASA. But I can also do this with an IOS router?

  Please let me know how if this is possible.

  Also is it true that the IOS routers are not affected to hear bug bleed? SSL VPN and SSL VPN with Anyconnect page is also save?

  http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/CIS...

  But I am in any way interested in using IPSec and SSL VPN on a router IOS...

  It's true - CCP does not yet offer the options to configure a VPN IPsec with IKEv2.

  The configuration guide (here) offers detailed advice and includes examples of configuration.

• 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.

  You must make sure that your internal traffic goes to the VPN client is NOT be NATT would be.

  You need to re - write acl 102 to something like: -.

  access-list 102 deny ip 192.168.4.0 0.0.0.255 192.168.4.0 0.0.0.255

  access-list 102 permit ip 192.168.4.0 0.0.0.255 any

• VPN client with counterpart on secondary ip address on the public interface of the router

  Hello

  On our office LAN, we have a Linux server than it hosting a VPN connection to a remote client.

  Do this to ISAKMP card on our Cisco router port connections to the internal ip address of the Linux host.

  However, we now want to allow our users to establish VPN connections to our local network using the unit of Cisco VPN Client.

  Of course, this would present challenges, as the ISAKMP our router port is mapped through an internal host.

  So, we tried to set up a secondary ip address on the router and VPN clients to connect to that.

  What we see in our newspapers is as follows:

  Phase 1 is very well established, and the VPN Client prompts the user for a user name and password.

  Authentication of the phase 2 starts, but the router says it's is not to receive a proposal of hash of the client.

  185 12:18:06.943 09/03/11 Sev = Info/4 IKE / 0 x 63000014
  RECEIVING< isakmp="" oak="" info="" *(hash,="" notify:no_proposal_chosen)="" from="">

  (in this case, where x.x.x.x is the secondary ip address on the public interface)

  After that, the Phase 1 SA is removed and the connection fails.

  My understanding is that the Phase 2 negotiation takes place with the ip address assigned to the client in Phase 1, which suggests that the problem occurs because the client communicates with the main on the interface ip address, and no secondary ip address.

  When remove us the mapping of port isakmp and the VPN client to connect to the primary ip address, everything works fine.

  Question:

  It is possible to establish 2 router VPN Client uses a secondary ip address?

  If not, is there some way I can implement the port mapping so that it occurs, the connection comes from a specific ip address?

  Garreth

  Should be supported on IOS.

  The command is crypto ctcp port...

• Microsoft VPN client through 857 router ADSL

  Hello

  I've set up an adsl router 857 with CP Express (web interface) with a standard firewall and NAT configuration.

  router seems to work very well apart from connections outbound pptp.

  I can't use the MS VPN client to connect to our PPTP server in a remote location. I don't try to use VPN on the router 857, allow just to pass through of my laptop computer behind the router to an external vpn server.

  Instantly, the client goes to "Check Userbane and password" then crashes on this during a minute or two before failing.

  Any suggestions would be apprecated.

  Thank you
