The VPN client connection

• 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?

  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.

• VPN Client connection - Hong Kong to the United States.

  We have a PIX 515E with active VPN. In the United States, users have no problem connecting with the VPN client.

  However, we have a user in Hong Kong, who has problems. It can connect to the external interface and the connection. The user is assigned an IP address from the pool of reserve, but cannot connect to our server here in the States or internal ping even one of the ip addresses.

  Is there another config that needs to be done?

  Yes, the do config mode:

  ISAKMP nat-traversal

  Save with: write mem - and your done.

  Download now your username in Hong KONG to establish the connection of the VPN client and try and ping a server in-house on your side. And make sure that the MS XP firewall is disabled.

  Let me know how you go and if this does not solve your problem please rate another post could seek the same solution!

• Maintenance of the internal DNS after connecting to the VPN Client

  We connect to the VPN client, all day and I wanted to know if there is a way to continue to use our internal LAN DNS when you are connected. For example, when I connect to the VPN client, our mail server internal and the dns resolves the public IP address.

  Thank you

  You can set up the split-dns service, but which can be configured at the vpn your client device, because you only connect with vpn client and normally politicians vpn client get pushed vpn headend unit.

  Here is the split-dns command if your customer comes to run ASA firewall, and they allow you to configure:

• IP address connection sets using the VPN Client

  Hello world. I'm using a VPN Client when I establish a VPN Tunnel with a 1600 router, and I have a question.

  Can I assign a fixed IP address in the client, instead the router send to random addresses from customer?

  What I would he do this?

  It would be in the configuration of the VPN client, or in the configuration of the router?

  If so, I'm doing this?

  Do I need another tool, or other software or hardware to do?

  any help is hope...

  Thank you...

  Hello

  I don't think that there is a simple way to do this.

  However, if you create a different groupname for the user who needs a static IP address, I think you should be good to go

  So what you need to do, create a new pool of addresses. Make the start and end ip address be the same (this is the address to which you want to assign to the VPN user)

  Configure another ipsec on the router group and bind the new pool to this group

  Ask your VPN client to connect to this group

  Hope that helps

• Linksys Cisco VPN Client connection drops

  I have a Linksys BEFVP41 V2. I have a PC running Windows XP SP2 with customer VPN Cisco 5.0.00.0340. I have a problem when I log in the VPN client with my employer network. It seems to be ok. No problem to do the job, hit their proxy server, etc.. All of a sudden, the connection drops. It seems to 'freeze' the network. No surfing, without PuTTY. Sometimes 5 minutes after the connection or 3 hours later. I have to disconnect the VPN connection, and then reconnect. What could be the problem? My MTU is set to 1432. The Windows Firewall has exceptions for ports 10000, 4500 and 62515. I have a network in place at 172.20.x.x... not the default or typical 10.x.x.x network. Firmware is 1.01.04 on the router.

  
  

• Routing problem between the VPN Client and the router's Ethernet device

  Hello

  I have a Cisco 1721 in a test environment.

  A net 172.16.0.0/19 simulates the Internet and a net 192.168.1.0/24 simulates the net, the VPN tunnel must go to (intranet).

  The net 172.16.0.0 depends on the router 0 FastEthernet, Intranet (VPN) hangs on Ethernet 0.

  The configuration was inspired form the sample Configuration

  "Configuring the Client VPN Cisco 3.x for Windows to IOS using Local extended authentication"

  and the output of the ConfigMaker configuration.

  Authentication and logon works. Client receives an IP address from the pool. But there's a routing problem

  side of routers. Ping client-side - do not work (the VPN client statistics that count encrypt them packets, but not to decrypt).

  Ping the router works too, but decrypt and encrypt customer statistics in VPN packets count progressive

  (customer has a correct route and return ICMP packets to the router).

  The question now is:

  How to route packets between the Tunnel and an Ethernet device (Ethernet 0)?

  conf of the router is attached - hope that's not too...

  Thanks & cordially

  Thomas,

  Can't wait to show something that might be there, but I don't see here. You do not have the card encryption applied to one of the interfaces, perhaps it was not copied. Assuming your description you do it, or should it be, applied to the fa0 and you are connected. Try how you ping? Since the router or a device located on E0? If you ping the router, you will need to do an extended ping of E0 to the ip address of the client has been assigned. If your just ping the router without the extension, you will get sales and decrypts that you declare on the client. Have you tried to ping from the client to interface E0? Your default route on the router is pointing to fa0? You have a next hop to affect? You have several NIC on the client pc? Turn off your other network cards to check that you don't have a problem with routing on the client if you have more than one.

• Need a guide to configure the VPN Client

  Hello...

  I vpn in my 506th pix and I have ver.4.0.1 software vpn client installed on the other pc (on the outside). In the firewall, there are two types of vpn; VPN site to site and remote vpn access. We use vpn for remote access to allow the vpn client to access our server right?

  This is all new to me and could you give an example how to configure vpn inside my firewall in CLI or PDM command and how to configure the software vpn client.

  Please help us beginners cisco

  Tonny

  Tony,

  Try chanigng a cisco and see if it solves... but otherwise, since you changed the PIX outside IP now, you will be able to make VPN connections to the new public IP address now, if it is routed on the internet.

  can you please try to connect now and let us know what is happening?

• VPN client connection script

  Is it possible to run a login script that makes things like drive mapping when a user signs in their business with the VPN client network.

  You can enable the 'Auto Connect before Logon' feature in the client and you should be able to connect to the hub, connect on the NT domain and run scripts.

• Is there a 64-bit version of the VPN Client for the coming of Vista?

  Is there a 64-bit version of the VPN Client for Vista to come for VPN 3000 series concentrators?

  Hello

  A bit is a tour here.

  According to Cisco:

  Install the VPN Client on a Vista 64 bit Machine will cause an error 1721

  Cisco IPSec Client does not support 64-bit. If the user requires a 64-bit support, upgrade path is to use the Cisco AnyConnect VPN Client instead, that supports 64-bit. Note that the AnyConnect Client supports only SSL VPN (CSCsi26069) connections.

  So if you want to go with 64-bit, you need SSL support on the VPN 3000 series and replace all IPSEC with SSL connections.

  Please rate if this helped.

  Kind regards

• Roads remain in the routing table after disconnecting from the vpn client

  I am facing this problem for my clients and the easy vpn server.

  My Cisco 3825 has an easy vpn server configuration with an ip pool. When one of the customer disconnects and isakmp and ipsec his deleted by the router itself. The route pointing to the ip address of the ip pool is still in the routing table. This time, another vpn client connects and get the ip address of the ip even pool. But this new vpn client connected is located on a different interface of the router. Thus, an extreme problem happen! A route to 2 next hops is created! So bad!

  Someone else can help me? How can I delete the wrong way?

  Thank you!

  Jason Lam

  It can be useful to upgrade because he accompanied several questions IPP in earlier versions of the code with the roads not removed during the SA goes down, etc.

• Unable to access the VPN Client LAN

  I configured a 877 for VPN Client Access. The Client authenticates and connects and receives an IP address off the coast of the pool of intellectual property. However, he is unable to access anything on the IP network.

  I have included my router config. The VPN Client is v5.0.05.0290.

  Any ideas on what I'm missing?

  Can try reverse our ACL VPN-Client, I think that it is written in the wrong way

  For example:

  VPN-Client extended IP access list

  Note * permit VPN Client pool *.

  IP enable any 192.168.201.0 0.0.0.255

  or more precise

  VPN-Client extended IP access list

  Note * permit VPN Client pool *.

  192.168.1.0 255.255.255.0 ip permit 192.168.201.0 0.0.0.255

• The VPN client user authentication

  When users connect to our network remotely via VPN user name field is already filled with the last person who logged. I know that they just delete the username and enter their own, but is there a way the client can be configured to where the username field will be always empty for all those who want access to the network via VPN? We have an ASA 5510 with version 7.0 (8) and a windows 2003 with IAS server for windows authentication. Thank you!

  Hello

  In FCP, you can configure a single line is not editable by the user (or the vpn client).

  Simply insert an attack! Like this

  ! Username =

  ! SaveUserPassword = 0

  ! UserPassword =

  ! enc_UserPassword =

  Subsequently the vpn client will not save registrations for these settings more.

• PIX: Cisco VPN Client connects but no routing

  Hello

  We have a Cisco PIX 515 with software 7.1 (2). He accepts Cisco VPN Client connections with no problems, but no routing does to internal networks directly connected to the PIX. For example, my PC is affected by the IP 172.16.2.57 and then ping does not respond to internal Windows server 172.16.0.12 or trying to RDP. The most irritating thing is that these attempts are recorded in the system log, but always ended with "SYN timeout", as follows:

  We tried to activate and deactivate "nat-control", "permit same-security-traffic inter-interface" and "permit same-security-traffic intra-interface", but the results are the same: the VPN connection is successfully established, but remote clients cannot reach the internal servers.

  I join all the details of the cryptographic algorithms because the VPN is successfully completed, as I said at the beginning. In addition, routing tables are irrelevant in my opinion, because the inaccessible hosts are directly connected to the internal LAN of the PIX 515.

• The dynamic firewall application on the VPN Clients with ASA

  Hello

  I'll put up a Cisco ASA to complete the remote VPN client connections, but I want to assure you that the dynamic firewall is enabled on the client.

  I know it's possible with the VPN concentrator, but cannot see any documentation detailing that can be performed on an ASA.

  Anyone encountered this?

  Thank you

  I believe you can use Group Policy settings to configure the firewall client.

  You can find more information about this feature in the migration to http://www.cisco.com/en/US/docs/security/asa/asa72/vpn3000_upgrade/upgrade/guide/migrate.htmlguide.
