• Cannot ping inside the vpn client hosts. It's a NAT problem

  Hello everyone, I'm running into what seems to be a cause of exclusion with an IOS IPSEC VPN NAT/nat. I can connect to the VPN with cisco IPSEC VPN client, and I am able to authenticate. Once I have authenticate, I'm not able to reach one of the guests inside. Below is my relevant config. Any help would be greatly appreciated.

  In my view, the acl applied to customer is back. It must allow traffic from the internal network to the pool of customers.

  To confirm, you can open the Cisco VPN client statistics (after login) then go in the route Details tab. We should see the networks you should be able to reach the customer. Make sure that the good ones are here.

• VPN client and contradictory static NAT entries

  Hello, we have a VPN IPSEC implemented on a router for remote access. It works very well, for the most part. We have also a few PAT static entries to allow access to a web server, etc. from the outside. We deny NATting from the range of IP addresses for the range of VPN client and it works except for entries that also have PAT configurations.

  So, for example, we have web server 10.0.0.1 and a PAT redirection port 10.0.0.1: 80 to the IP WAN port 80. If a VPN client tries to connect to 10.0.0.1: 80, the syn - ack packet back to the customer WAN IP VPN on the router! If the VPN client connects to the RDP server 10.0.0.2:3389, it works very well that this server is not a static entry PAT.

  Is there a way to get around this?

  Thank you!

  There is a way to get around, use the same settings you have for your dynamic nat in your nat staitc entries, something like this:

  Currently, it should show as:

  IP nat inside source static XXXXX XXXX 80 80

  you need to take it

  IP nat inside source static 80 XXXX XXXX 80 map route AAAA

  When your itinerary map YYY refers to something with an acl that you refuse traffic from inside your router for the pool of vpn

  IP Access-list ext nonat

  deny ip 10.0.0.0 0.0.0.255

  Licensing ip 10.0.0.0 0.0.0.255 any

  route allowed AAAA 10 map

  match ip address sheep

  You even need all the static PAT

• Connected to the ASA via the "VPN Client" software, but cannot ping devices.

  I have a network that looks like this:

  

  I successfully connected inside the ASA via a software "Client VPN" tunnel network and got an IP address of 10.45.99.100/16.

  I am trying to ping the 10.45.99.100 outside 10.45.7.2, but the ping fails (request timed out).

  On the SAA, including the "logging console notifications" value, I notice the following message is displayed:

  "% 305013-5-ASA: rules asymmetrical NAT matched for flows forward and backward; "Connection for icmp src, dst outside: 10.45.99.100 inside: 10.45.7.2 (type 8, code 0) rejected due to the failure of reverse path of NAT.

  I have a vague feeling that I'm missing a NAT rule of course, but not all. What did I miss?

  Here is my configuration of ASA: http://pastebin.com/raw.php?i=ad6p1Zac

  Hello

  You seem to have a configured ACL NAT0 but is not actually in use with a command "nat"

  You would probably need

  NAT (inside) 0-list of access inside_nat0_outside

  He must manage the NAT0

  Personally, I would avoid using large subnets/networks. You probably won't ever have host behind ASA who would fill / 16 subnet mask.

  I would also keep the pool VPN as a separate network from LANs behind ASA. The LAN 10.45.0.0/16 and 10.45.99.100 - 200 are on the same network.

• Cannot ping via remote VPN

  Hi all

  I have a client who uses a 506e with the cleint 4.02 for the remote VPN Cisco. The pix is multiple inside roads. The first network inside is 192.168.1.X and E1 of the 506 is 192.168.1.1. The second network is 10.71.56.X.

  The problem is as soon as the VPN is connected I can ping any host on the 192.168.1.X, but not anything on the 10.71.56.X network. Without netbios or the other. From the PIX, I can ping hosts on two internal networks.

  Here is the config below. Thank you!

  You use 10.71.56.0 255.255.255.0 in two places

  you route to it via 192.168.1.1, but you're also allocation of addresses for vpn clients. Guests who are on the segment 10.71.56.0/24, if they manage to get the connected vpn client package (which is assigned a 10.71.56.x) address, would not send the response packet to this request on the local subnet, the router that has the 192.168.1.1 interface, which is what would be needed to make it work.

  You must use a different network for your vpn clients block - you cannot use the same ip through two different networks space.

• Cannot Ping across the VPN remote access

  Hello world

  I hope I posted this in the right place!

  I'm a bit new to Cisco IOS, so please forgive me if I ask a stupid question!

  We have a firewall of 515E PIX 6.3 (4) on which I used the VPN Wizard to set up a remote access VPN the Cisco VPN client on the external interface.

  When I connect to home on my laptop Windows XP Pro SP2 running Cisco VPN Client 4.0.5(C) I seem to be able to connect to most of the network resources (IE file shares, I can RDP into servers, etc.) but I can't seem to be able to ping anything : I just request times out.

  I'm sure it's something stupid I've done (or not done).

  I have attached my config and would be grateful if someone could take a look and point me in the right direction.

  Thanks in advance for your help,

  Peter.

• VPN site to site access via a VPN client

  Hi all

  From our headquarters, we use a vpn site-to-site to connect to another site and it works great.

  We have just configured the VPN client on our headquarters, remote VPN user can access the LAN in the seat.

  We need the remote user can also access the LAN on the other site, but it does not work.

  The site to site VPN and VPN client are configured on the same device, using even outside the interface.

  Vpn client address pool is already included in the address that is allowed to go through the site to site VPN.

  We would like to know if it is possible to access the site to site VPN, connecting to the VPN client and when the architecture is as above?

  in the case where we use different devices and different internet connection for client VPN and site to site VPN, we can access the other site by the remote user VPN LAN?

  Kind regards

  Since you already have 10.13.0.0/16 in your site to site crypto ACL, which already includes the pool vpn so you need not configure it specifically.

  You are missing the following command:

  permit same-security-traffic intra-interface

  ACL split tunnel should be standard ACL as follows:

  access list ACL-CL-VPN allow 10.13.0.0 255.255.0.0

  access list ACL-CL-VPN allow 10.14.0.0 255.255.248.0

• The VPN Clients cannot Ping hosts

  I'll include a post my config. I have clients that connect through the VPN tunnel on the 180.0.0.0/24 network, 192.168.1.0/24 is the main network for the office.

  I can connect to the VPN, and I received a correct address assignment. I belive tunneling can be configured correctly in the aspect that I can always connect to the internet then on the VPN, but I can't ping all hosts on the 192.168.1.0 network. In the journal of the ASDM debugging, I see pings to the ASA, but no response is received on the client.

  capture capin interface inside match icmp 192.168.1.x host 180.0.0.x

  capture ASP asp type - drop all

  then make a continuous ping and get 'show capin cap' and 'asp cap.

  -then check the ping, the 'encrypted' counter is increasing in the VPN client statistics

  I would like to know about it, hope this helps

• Itineraries other nets will be lost when using the vpn client?

  I have a very general question. I intend to implement a security solution for the extranet partners to connect to our intranet using VPN client. IPSec will close on the external interface of the Cisco PIX firewall v6.3.

  Now, my consirn is, I downloaded the vpn client to test but I saw no advance settings to define what network traffic will pass through the IPSec tunnel and which will be routed normally. Is it by default all traffic passing through VPN? Is that what it means if there are other networks using their default route, they will not be able to achieve? (i.e. the Internet).

  Thank you.

  That would depend on how you set up the PIX. You can allow the VPN to your site and access to the Internet at the same time. This is called the split tunneling. It is configurable on the PIX, not the customer.

  This link might help you get started, but I'm sure that there stronger links.

• ASA Anyconnect VPN do not work or download the VPN client

  I have a Cisco ASA 5505 that I try to configure anyconnect VPN and thought, I've changed my setup several times but trying to access my static public IP address of the external IP address to download the image, I am not able to. Also when I do a package tracer I see he has been ignored through the acl when the packets from side to the ASA via port 443, it drops because of the ACL. My DMZ so will he look like something trying to access the ASA via the VPN's going to port 443. Here is my config

• 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 Schmidt

  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.

• 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.

• 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.

• Between the VPN Client and VPN from Site to Site

  Looking for an example of ASA 8.0 configuration allowing traffic between a Cisco VPN client host and destination of remote access connected via LAN/Site-to-Site tunnel.  The remote access client and the tunnel site-to-site terminate on the same device of the SAA.

  Thanks in advance.

  Hi Rey,

  Here is an example of a config for what you are looking for.

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

  I hope this helps.

  PS: This uses GANYMEDE + for authentication, you can replace it with your authentication method.

  Kind regards
