NAT overlapping with remote VPN access

• is it possible this with remote vpn access?

  Hello

  I have access to my corporate network through the VPN Cisco (software) customer and it goes through the vpn to access configuration remote ipsec on an ASA 5510. Everything works fine.

  But now that connect to the corporate network users also need access to remote sites connected by tunnels VPN site to site networks: tunnels IPSec between mentioned ASA5510 and distance ASA5510s and ASA5505s in the branches.

  Is this possible?

  If so what shoud I consider make it works?

  My setup looks like

  business network: 10.1.1.0/24

  Remote vpn clients receive the ip addresses of: 10.0.5.0/28

  Branch on the remote 1 network: 10.1.10.0/24

  network of remote sites 2: 10.1.20.0/24

  3 remote site network: 10.1.30.0/24

  There rule for NAT exemption which exempts the networks 10.1.10.0/24, 10.1.20.0/24, 10.1.30.0/24

  All traffic on the local network 10.1.1.0/24 have complete ip connectivity with all networks in the branches. The PROBLEM is that the remote vpn clients can reach only local network 10.1.1.0/24, but not the remote networks.

  The ASAs in remote sites has created NAT exemption to the two local network 10.1.1.0/24 and network 10.0.5.0/28 remote access clients, but as I said, it won't. Help, please!

  Thanks in advance!

  Yes, you can...

  Let's take 1 remote sites for example network: network of agencies 1 (10.1.10.0/24):

  Company ASA:

  -If you have split tunnel configured for the VPN Client, you must also add the remote site network in the list (10.1.10.0/24).

  -Crypto ACL between the company ASA and ASA 1 remote sites must have added the following:

  10.0.5.0 ip access list allow 255.255.255.240 10.1.10.0 255.255.255.0

  -' same-security-traffic permit intra-interface' must be configured

  On the remote control of the branch 1 ASA:

  -Crypto ACL between remote branch 1 ASA and company ASA must have added the following:

  ip 10.1.10.0 access list allow 255.255.255.0 10.0.5.0 255.255.255.240

  -Rule of exemption NAT to exempt traffic:

  ip 10.1.10.0 access list allow 255.255.255.0 10.0.5.0 255.255.255.240

  Clear the tunnels of both ends and test the connectivity.

  I hope this helps.

• Remote VPN access - add new internal IP address

  Hello

  I have an existing configuration of Cisco VPN client in ASA 5510 for remote access.

  -------------------------------------

  Name of the Group: ISETANLOT10

  Group password: xxxx
   
  IP pool: lot10ippool, 172.27.17.240 - 172.27.17.245
   
  enycrption: 3DES
  authentication: SHA
  ------------------------------------
  the connection was successful, and I was able to ping to the internal server 172.47.1.10.
  Now, there is demand for remote access VPN even can do a ping to access a new server within LAN, 172.57.1.10 & 172.57.1.20
  But with the same VPN access, I was unable to ping the two new IP.
  How can I add both IP in order to make a ping by using the same configuration of remote access VPN?
  I have attached below existing config (edited version)

  Remote VPN access must allow the connection, but I'm guessing that your ASA does not know how to get to the two new destinations.

  You have a name and a static route to the job to 172.47.1.10 Server:

  name 172.47.1.10 NarayaServer description Naraya Server

  route inside NarayaServer 255.255.255.255 172.27.17.100 1

  .. but no equivalent for the two new hosts. As a result, all traffic of ASA destiny for them will attempt to use the default route (via the external interface).

  If you add:

  route inside 172.57.1.10 255.255.255.255 172.27.17.100

  route inside 172.57.1.20 255.255.255.255 172.27.17.100

  (assuming this is your correct entry), it should work.

• WebVPN and remote VPN access

  Hello

  Is there a difference between WebVPN and remote VPN access or they are the same.

  Thank you.

  access remote vpn consists of

  -IPSEC VPN remote access. It is part of the ASA, no permit required, requires pre-installed Client from Cisco VPN IPSEC on PC

  -with AnyConnect SSL VPN remote access. It requires licensing of SSL VPN on SAA. AnyConnect client can be installed automatically on the PC with the launch of web.

  -with Essentials AnyConnect SSL VPN remote access. Beginning with ASA 8.2 (1), almost license $ 0. It's the same AnyConnect client as in the previous article, but it cannot be installed automatically with the launch of web. It must be previously installed as of Cisco IPSEC VPN client.

  -webvpn aka clientless vpn. It is a portal HTTPS which allows HTTP connections, file sharing, telnet, RDP and much more (with smart tunnels) resources without having to install a real client on the PC. It requires licensing of SSL VPN on SAA. It cannot be used if "AnyConnect Essentials" license is activated on SAA after 8.2 (1)

  Kind regards

• ASA5505 can transfer clients to remote VPN access to the local network

  I have currently ASA 5505 and 2911-router and I am trying to configure the VPN topology.

  Can ASA5505 you transmit to remote VPN access clients LAN operated by another router?

  These two cases are possible? :

  (1) ASA 5505 and 2911-router are separate WAN interfaces, each connected directly to the ISP. But so can I connect an other interfaces LAN of ASA 5505 in a switch managed by 2911 router customers to distance-SSL-VPN to inject into the local network managed by the router?
  (2) ASA 5505 is behind router-2911. May 2911 router address public ip or public ip address VPN-access attempts have directly be sent to ASA 5505 when there is only a single public ip address address available?
  Long put short, ASA 5505 can inject its clients to remote-access-VPN as one of the hosts on the local network managed by 2911-router?
  Thank you.

  I could help you more if you can explain the purpose of this configuration and connectivity between the router and ASA.

  You can activate the reverse route on the dynamic plane on the SAA. The ASA will install a static route to the customer on the routing table. You can use a routing protocol to redistribute static routes to your switch on the side of LAN of the SAA.

• Remote VPN access without end

  Hi all. I have a 5510 I use for tunneling ipsec l2l as remote access. I've been watching this thing so long as I'm goofy.

  My tunnel l2l is up and happy. Hosts can talk to each other.

  My RA is happy that I can connect with a vpn client. Unfortunately, I can't access anything other than the SAA itself when I am connected. I can't ping the host inside.

  I need to be able to access the host of 10.0.5.10/26 inside the interface which is 10.0.5.1/26. I have attached the config.

  Can we see some glaring problems? I think its likely an ACL problem, I'm kinda new to this kind of things well and I don't know if I'm doing things.

  One thing I noticed, is that when I check my ipconfig after the connection to the vpn. I get this...

  IP address: 10.0.5.20

  Subnet mask: 255.255.255.192

  Default gateway: 10.0.5.20

  This seems like a strange gateway...

  Thank you!

  Add...

  ISAKMP nat-traversal

  In addition, changing your vpn to another subnet client pool. It should not be on the same subnet as your interior.

  IP local pool gsa 10.0.6.0 - 10.0.6.254 mask 255.255.255.0

  inside_nat0_outbound to access extended list ip 10.0.5.0 allow 255.255.255.192 10.0.6.0 255.255.255.0

• Cannot TFTP remote VPN access

  I am accessing a remote site with a VPN client. I am trying to download the config of the router for this laptop remotely with a server tftp on it.

  This does not work, and I think it is because it is the supply of the external interface. Is this correct? If so how to fix it?

  Thanks for help.

  Antony

  To fix this problem set up the router with ip tftp source interface

  This will get the router to use the address of the interface specified as the source for TFTP.

• Remote VPN access

  I'm trying to migrate some VPN remote access for some directors of the power of a router to an ASA 5500. The profile I'm using is vpnclient. When I add the access lists to join networks (10,200 and 10.25) inside what it appears on the route print command is the network of 10,200. I can ping to a server or a client, but cannot ping any network device. I can't ping any device in the subnet 10.25. Any help in this would be greatly appreciated. Here is the config.

  Hi Mitch,

  Ensure that subnet 10.25.x.x pass thru nat (inside) 0 for example access list 102

• IPsec over UDP - remote VPN access

  Hello world

  The VPN client user PC IPSEC over UDP option is checked under transport.

  When I check the details of the phase 1 of IKE ASDM of user login, it shows only UDP 500 port not port 4500.

  Means that user PC VPN ASA there that no device in question makes NAT.

  What happens if we checked the same option in the client IPSEC VPN - over UDP and now, if we see the port UDP 4500 under IKE phase 1 Connection Details

  This means that there is now ASA a NAT device VPN Client PC, but he allows IKE connection phase 1?

  Concerning

  MAhesh

  Hello Manu,

  I suggest to use the following commands on your ASA have a look at these ports as the test of VPN connections. The command that you use depends on your level of software as minor changes in the format of the command

  View details remote vpn-sessiondb

  view sessiondb-vpn remote detail filter p-ipaddress

  Or

  View details of ra-ikev1-ipsec-vpn-sessiondb

  display the filter retail ra-ikev1-ipsec-vpn-sessiondb p-ipaddress

  These will provide information on the type of VPN Client connection.

  Here are a few out of different situations when connecting with the VPN Client

  Above are examples for your reference. I must also say that I am absolutely not an expert when it comes to virtual private networks in general. I had to learn two firewall/vpn basically on my own, as during my studies, we had no classes related to them (which was quite strange).

  While I learned how to set up VPN and troubleshoot them I think I missed on the basic theory. I had plans to get the title Associates CCNA/CCNP certifications but at the moment everything is possible. Don't have the time for it.

  I guess that you already go to the VPN security CCNP Exam?

  Hope this helps and I hope that I didn't get anything wrong above

• Cisco ASA 5505 remote VPN access to the local network

  I have installed two ASA 5505 VPN site to site that works perfectly.  Now, I also need to have 1 customer site to remote access VPN with Cisco VPN dialer.  I can get the VPN dialer to connect the VPN and get a VPN IP address, but I do not have access to the remote network.  can someone take a look and see what I'm missing?  I have attached the ASA running config.

  Apologize for the misunderstanding.

  To access the remote vpn client 10.10.100.x subnet, the vpn-filter ACL is the opposite.

• IPSec VPN (remote VPN access) - dynamic NAT

  Hello dear group

  I like ASA 5510 is configured for remote access VPN, ASA authenticates Clients remoter with Radius Server (accounting software) and will be assigned an address IP of VPN-pool (172.16.20.0/24). Prose all in use of authentication with radius server is successful, but there is no any Internet browsing on the client side. I've set up a dynamic NAT rule on the external interface of SAA, I write in the following:

  Interface: outside

  Source: VPN-users object (address pool 172.16.20.0/24)

  The translation of the output interface.

  the NAT rule to above does not. (I think that traffic is not clothed with VPN POOL address via external interface)

  Note: this VPN users access the INTERNET only. (because of this, the pool address range is different with inside the Network Interface)

  Its a favor if you help me how NAT.

  Thank you

  Best regards

  Hello

  Would really need to see your current NAT configurations to the CLI format to determine the problem.

  Naturally, the problem could be as simple as missing the following command on the SAA

  permit same-security-traffic intra-interface

  This command is required on the SAA for traffic to come through an interface and let the same interface. In your case this interface would be "Outside" the customer VPN traffic arrives at the ASA via this interface what is leaving through this interface to the Internet.

• Don't host any remote VPN access

  Hello guys,.

  I have an ASA 5505 with two tunnels, a Site to Site (between two ASA 5505), and also, I added a remote access VPN using the factor of Cisco's VPN. The thing I discovered is that the Site to Site connection, I can reach the hosts of the LAN, but the use of the VPN Client I only can reach the inside Interface of the ASA, but not for the hosts.

  Something is perhaps missing from my ACL but I was not able to determine what it is. You give me a hand on this?

  Attached my config file, and the LAN behind the ASA consist in a couple of VLAN segment 192.168.0.0 24 receives the Client VPN IP to the 10.10.10.X segment

  Thanks in advance,

  Hi David,

  You are missing a statement of NAT exemption.

  Need to add this:

• Cram session for the establishment of remote vpn access

  Our 'VPN guy' has recently left the company, and we demand to implement the remote access VPN 2 for two different customers very soon. I did a lot of lan connection database and things with cisco switches/routers, so I'm familiar w / cli, but I've never actually set up a virtual private network. I'm going to have to become a competent REALLY fast. Does anyone know of a good place for me to start (list of control/walkthru/whatever!) learn how to configure ipsec VPN for remote access? Of course, I did some research on cisco.com, but can't seem to find any guide "definitave" VPN remote access.

  A vpn will use a router in 1751, and the other will use a 831. In both cases we will use the cisco vpn client and radius authentication and authorization.

  I understand how VPNS work pretty well, but I am always a little scared...

  Take a look at this technology cisco.com guides.

  http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a00800946b7.shtml

  I used this as a base for my client connections.

• VPN site-to-site between two PIX 501 with Client VPN access

  Site A and site B are connected with VPN Site to Site between two PIX 501.

  Also, site A is configured for remote access VPN client. If a remote client connects to Site A, it can only get access to the LAN of Site A, it cannot access anything whatsoever behind PIX on Site B.

  How is that possible for a VPN client connected to Site A to Site B?

  Thank you very much.

  Alex

  Bad and worse news:

  Bad: Not running the 7.0 series PIX cannot route traffic on the same interface, the traffic is recived. Version 7.0 solves this ipsec traffic.

  Even worse: PIX 501 can not be upgraded to 7.0...

  A couple of things to think about would be the upgrade to hardware that can run the new IOS or allowing a VPN R.A. on site B.

  HTH Please assess whether this is the case.

  Thank you

• INTERNET VIA REMOTE VPN ACCESS

  We have a customer who wants to route all internet traffic to their remote sites of their internet connection to Headquarters. In other words, when users connect to corporate headquarters using Cisco VPN client on their PC, we need to route all internet traffic on through the firewall of the headquarters. Head office is running a ASA place all the VPN configuration. We have a number of virtual private network set up for this customer but would welcome suggestions as to the best way to configure this particular step.

  Thank you very much.

  Hello

  This looks like back or Hairpining for VPN clients, so they could access the Internet through the tunnel.

  In which case it is a ASA 8.2 or earlier:

  permit same-security-traffic intra-interface

  NAT (outside) 1 192.168.1.0 255.255.255.0---> range of IP addresses assigned to VPN clients.

  Global 1 interface (outside)

  In which case it is an ASA 8.3 or later:

  permit same-security-traffic intra-interface

  network vpn-pool objects

  subnet 192.168.1.0 255.255.255.0

  dynamic NAT interface (outdoors, outdoor)

  !

  On the configuration of VPN:

  mypolicy group policy attributes

  Split-tunnel-policy tunnelall

  !
  tunnel-group mytunnel General-attributes

  MyPolicy defaul-group-policy

  !

  Benefits:

  1-Internet access is controlled by the ASA.

  Disadvantages:

  1 Internet connection of the ASA is severely affected, it will be used by VPN clients to access the Internet.

  Alternative solution:

  Send all traffic to a Layer 3 internal device or a server that has an external Internet connection, so the ASA forwards all traffic to this device, if this device is able to perform web filterting advance as the unit of Microsoft IIS, then you would have a powerful way to control your users and that they access, thus preventing sites such undesirable sites for adults and animation.

  To do this, all you need is:

  Route within 0 0 192.168.10.1 tunnele---> where the 192.168.10.1 corresponds to the internal device responsible for providing Internet.

  * Remember that this device must have an external connection for Internet access, not on the SAA.

  Let me know.

  Portu.

  Please note any workstation that will be useful.
