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:

2009-01-06 23:23:01 Local4.Info 217.15.42.214% 302013-6-PIX: built 3315917 for incoming TCP connections (172.16.2.57/1283) outside:172.16.2.57/1283 inside: ALAI2 / 3389 (ALAI2/3389)

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 enclose the training concerned in order to understand the problem:

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.

Thank you very much.

can you confirm asa have NAT traversal allow otherwise, activate it in asa and vpn clients try again.

  • Cisco VPN Client connected, but no secure way.

    Hello

    I can connect to a VPN server smoothly, but once connected, I'm not able to reach all local resources. When I looked at the stats of customer VPN, it shows only a single route in 'Details of the route--> secure routes', 1.1.1.1 255.255.255.255. This is the reason why I can't access any resource. This could be the cause of this problem? How can I secure roads announcing cisco customer? I don't have access to the server, but I will ask the person who can make changes.

    Thank you.

    Kind regards

    Shivani,

    Split tunneling is what you're looking for, it will affect your secure routes.

  • Cisco ASA 8.4 (3) remote access VPN - client connects but cannot access inside the network

    I have problems to access the resources within the network when connecting with the Cisco VPN client for a version of 8.4 (3) operation of the IOS Cisco ASA 5510. I tried all new NAT 8.4 orders but cannot access the network interior. I can see traffic in newspapers when ping. I can only assume I have NAT evil or it's because the inside interface of the ASA is on the 24th of the same subnet as the network interior? Please see config below, any suggestion would be appreciated. I configured a VPN site to another in this same 5510 and it works well

    Thank you

  • VPN client connected but no ping nor access to privat network

    Hello

    I have a 1802w installed, a VPN client that can connect to the router and L2L connection, which works very well.

    On the router, I see that the client is connected, but no traffic passes. In sh crypto ipsec, I see that traffic is decrypted, but no packtets are encypted.

    Can someone point me in the right direction? I have the confs and debugs attached. Thanks for the help in advance.

    Erich

    Erich,

    Looking at your configuration, two things:

    1 - is the current running configuration. I see your Tunnel L2L is configured with an address of correspondence of 101, but I don't see a 101 ACL set on the router.

    2. your Split Tunnel must be reconfigured. Which means, the source and destination must be exchanged.

    SplitList extended IP access list

    permit ip 192.168.2.0 0.0.0.255 192.168.111.0 0.0.0.255

    Split Tunneling

    http://www.Cisco.com/en/us/Tech/tk59/technologies_configuration_example09186a00800a393b.shtml#Con4

    Also, the IP address pool you assign to clients, ensure that they are not part of a LAN on your side. If so, you can then run in routing problems.

    Kind regards

  • 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.


  • Cisco VPN Client anything cannot access through VPN on an ASA5505 8.4

    Hello

    Completely new to Cisco ASA and the need to get this working ASAP.

    8.4 (1) ASA 5505 is the secondary FW and I need to authorize all out and block everything coming, but for the VPN clients.  Since a jerk of Cisco, I used the ASDM and it's sorcerers to make this work, which may explain my situation.

    192.168.101.0/24 is the local network

    192.168.101.5 is the IP of ASA

    192.168.101.2 is the primary FW (and the default gateway for servers, I have to access through the VPN)

    10.10.101.0/24 is the VPN IP range (this can be what you want, I'm not married to it somehow)

    My Cisco VPN Client connects to the ASA and receives 10.10.101.1 IP address, but I get no connectivity to the ASA or any other 192.168.101.x or service server (tried RDP, telnet, ping, etc.)

    Configuration file is attached.

    Help pretty please!

    Thank you.

    Did you add a route for the VPN Pool on the main firewall to the ASA?

    Best regards

  • Allow Cisco VPN Client through the firewall?

    Hello

    How can I allow a cisco VPN client work from the inside of our network to an external IP address?

    We have customers who wish to make use of their Cisco VPN Client companies but our ASA blocks I think?

    Also (sorry to ask) a friend in South America is having the same problem but I am not hink they use Cisco, is there a default port used by the client to Cisco? then I can send this info?

    Thank you

    Generally, the ASA will allow the IPSEC from the inside to outside traffic. This is when you want it came outside and connect to you - this is where it gets creative. You restrict outgoing traffic at all? You deny all ip/tcp/udp outgoing?

    But may depend on if the remote end is compaitable NAT - T, and if they have configured. Another question would be how they allow VPN traffic go?

  • Problems to connect via the Cisco VPN client IPSec of for RV180W small business router

    Hello

    I tried to configure my router Cisco of RV180W as a customer VPN IPSec, but have encountered a problem that I hope someone can help me with. "" I managed to do the work of configuration so that the Cisco's VPN IPSec client authenticates successfully with the XAUTH user, I put on the router, but during the negotiation, the client ends with the following, which appears several times on the router error message: ' Mar 20 Oct 19:41:53 2015 (GMT + 0000): [r1] [IKE] ERROR: local configuration for > [34360] has no config mode.

    I've read around the internet and a number of people seem to say that the Cisco VPN Client is not compatible with the router, but the same thing happens to my iPhone VPN client.

    Is it possible that this can be implemented? Below, I have attached the full configuration files and the log files. Thank you much in advance.

    Correct, the RV180 is not compatible with the Cisco VPN Client.  The Iphone uses the Cisco VPN Client.

    You can use the PPTP on the RV180 server to connect a PPTP Client.

    In addition, it RV180 will allow an IPsec connection to third-party customers 3.  Greenbow and Shrew Soft are 2 commonly used clients.

  • 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,.

  • Cisco VPN client, PIX, and proxy

    Hi.I have problem in my company. We have users that go through a proxy server located in the DMZ of a PIX to the internet (allowed through the ACL of the DMZ on the outside, etc.). Which works very well.

    The problem arises when they use a Cisco VPN client to connect to another company, and they can no longer access the Internet, but may work via VPN to a remote site (client has been authorized by the Cisco PIX). Everything returns to normal when they no longer use the VPN client.

    Any ideas why this would happen?

    Without the proxy, browsing the internet via the vpn connection, or split tunnel is configured and you are leaving locally. If split tunnel is configured, the ip address of proxy server can overlap with the remote protected network.

    Fortunately, it is easy for you to know how the vpn is configured, just check the route details of vpn client statistics tab.

    Verify that the routing table local pc will also help you to solve this problem.

  • Routing issue of Cisco VPN Client ASA

    Hi, I use a Barracuda NG for firewalls and I would use a Cisco ASA 5505 for VPN Client connections. But I have the problem that I can't get a connection to the VPN PC connected to the internal network. But I can reach the VPN connected PC from the inside. Here is a diagram of my network:

    Here the IP Configuration and the routing of the Barracuda firewall table:

    I have a route on the Barracuda NG to the 10.10.10.0/24 network VPN Client on eth0.

    The 192.168.1.0/24 LAN I ping the Client comes with Client VPN 10.10.10.11 as it should. But I can't ping or access network resources in the local network for AnyConnected customer's PC that connected through the VPN.

    Can someone please help me solve this problem?

    When I tried to solve this I didn't choose which interface the Packet Tracer?

    The interface inside or DMZ interface?  Inside, he says it will not work with the dmz but the error did not help me

    Anyone here knows why it does not work?

    Hello

    Inside LAN is directly connected to the right firewall VPN... then I don't think you have to have the itinerary tunnele... can you try to remove the road tunnel mode and check.

    entrance to the road that is static to achieve 10.10.10.11 as its display is correct...

    Route by tunnel watch also with 255 administrative distance.  I've never used that in my scenarios... lets see...

    Have you tried to remove the following lines:

    IP nat inside source list 1 interface FastEthernet0/1 overload

    IP nat inside source list 2 interface FastEthernet0/1 overload

    IP nat inside source list 3 interface FastEthernet0/1 overload

    overload of IP nat inside source list 20 interface FastEthernet0/1

    And simply let this one:

    IP nat inside source map route SHEEP interface FastEthernet0/1 overload

    ?

    I have all the neceary allowed in the ACL of NAT, so you do not have individual lines for each network.

    Also, I noticed that your ACL 20 reads

    access-list 20 allow 192.168.200.0 0.0.0.255

    But your NAT ACL bed

    ip licensing 192.168.20.0 0.0.0.255 any

    I think you have a typo in there, you have a 200 on 20 and on the other.

    Check it out and let me know how it goes. Don't forget to clear the NAT table after deleting these lines:

    clear the ip nat trans *.

    I hope this helps!

  • Cisco vpn client is supported on the analogue ppp connection

    can someone pls tell me if we can use the client vpn cisco on a ppp connection analog and put a pix that is not PPPs running. If it works, then why do we need to VPN L2tp/ipsec. can someone pls tell me something abt it. It is very urgent.

    concerning

    Assane

    Assane,

    If I understand your question, you speak with PPP initially to get an IP address from your service provider, then use the Client VPN VPN in your Pix Firewall. If so, yes it is possible.

    To name a few reasons why PPTP or L2TP/IPSEC is used instead of Cisco VPN Client are:

    1. because companies have used a PPTP or L2TP/IPSEC solution for some time and are migrating to Cisco VPN

    2. do not install vpn on the PC client software

    3. won't pay for the VPN Client software licenses

    Let me know if it helps.

    Kind regards

  • Unable to connect via the Cisco VPN Client

    Hello

    I have configured remote access VPN to ASA and tries to connect via the Cisco VPN Client 5.0

    I am not able to connect and watch the journal on the SAA

    ASA-3-713902: Group = xxxxx, IP = x.x.x.x, withdrawal homologous peer table is placed, no match!

    ASA-4-713903: Group = xxxxx, IP x.x.x.x, error: impossible to rmeove PeerTblEntry

    ASA does not support the K9 i.e. VPN - DES is enabled and VPN-3DES-AES is disabled.

    What could be the reason.

    Concerning

    Hi, I had this same problem, here is the solution:

    When you perform a debug crypto isakmp 255, so you see that the cisco vpn client does not support SHA +, you must use MD5 + AN or sha with 3DES/AES.

    Be careful, this debugging is very talkative, but that's the only way I found to get ITS proposal on debugging.

    Well, change your strategy using MD5 isakmp / OF would do the trick.
