• Unique password on SAA for VPN access

  Hello

  It is posibble create a unique password on SAA for VPN access?

  I googled a bit and found a few solutions with unique servers from other suppliers.

  I wonder if this is possible without additional hardware/software.

  Hello

  you will need to integrate the VPN with the RSA. they will give you once the configuration of the password tokenized soft or hard token.

  Outside of RSA, there is no other choice I guess.

  I hope this helps.

  Kind regards

• Making the NAT for VPN through L2L tunnel clients

  Hi.I has the following situation in my network. We need for users who log on our site with the VPN clients to connect to another site via a tunnel L2L. The problem is that I need NAT addresses from the pool of VPN client in another beach before going on the L2L tunnel because on the other side, we have duplication of networks.

  I tried to do NAT with little success as follows:

  ACL for pool NAT of VPN:

  Extended list ip 192.168.253.0 access TEST allow 255.255.255.0 192.168.0.0 255.255.255.0

  Extended list ip 192.168.253.0 access TEST allow 255.255.255.0 192.168.5.0 255.255.255.0

  NAT:

  Global 172.20.105.1 - 172.20.105.254 15 (outdoor)

  NAT (inside) 15 TEST access-list

  CRYPTO ACL:

  allowed ro access list extended LAN ip 255.255.0.0 192.168.0.0 255.255.255.0

  allowed ro access list extended LAN ip 255.255.0.0 192.168.5.0 255.255.255.0

  IP 172.20.105.0 RO allow extended access list 255.255.255.0 192.168.0.0 255.255.255.0

  IP 172.20.105.0 RO allow extended access list 255.255.255.0 192.168.5.0 255.255.255.0

  permit same-security-traffic intra-interface

  Am I missing something here? Something like this is possible at all?

  Thanks in advance for any help.

  We use the ASA 5510 with software version 8.0 (3) 6.

  You need nat to the outside, not the inside.

• Policy NAT for VPN L2L

  Summary:

  We strive to establish a two-way VPN L2L tunnel with a partner. VPN traffic is one-to-many towards our partner, and our partner they need of a many-to-one to us (they need to access a host on our network). In addition, our partner has many VPN, so they force us to use a separate NAT with two private hosts addresses, one for each direction of the tunnel.

  My initial configuration of the tunnel on my grown up side of Phase 1, but not IPSec. Partner ran debug that revealed that my host did not address NAT'd in the NAT policy. We use an ASA5520, ver 7.0.

  Here is the config:

  # #List of OUR guests

  the OURHosts object-group network

  network-host 192.168.x.y object

  # Hosts PARTNER #List

  the PARTNERHosts object-group network

  network-host 10.2.a.b object

  ###ACL for NAT

  # Many - to - many outgoing

  access-list extended NAT2 allowed ip object-group OURHosts-group of objects PARTNERHosts

  # One - to - many incoming

  VIH3 list extended access permit ip host 192.168.c.d PARTNERHosts object-group

  # #NAT

  NAT (INSIDE) 2-list of access NAT2

  NAT (OUTSIDE) 2 172.20.n.0

  NAT (INSIDE) 3 access-list VIH3

  NAT (OUTSIDE) 3 172.20.n.1

  # #ACL for VPN

  access list permits extended VPN ip object-group objects PARTNERHosts OURHosts-group

  access allowed extended VPN ip host 192.168.c.d PARTNERHosts object-group list

  # #Tunnel

  tunnel-group type ipsec-l2l

  card <#>crypto is the VPN address

  card crypto <#>the value transform-set VPN

  card <#>crypto defined peer

  I realize that the ACL for the VPN should read:

  access allowed extended VPN ip host 172.20.n.0 PARTNERHosts object-group list

  access allowed extended VPN ip host 172.20.n.1 PARTNERHosts object-group list

  .. . If the NAT was working properly, but when this ACL is used, Phase 1 is not even negotiating, so I know the NAT is never translated.

  What am I missing to NAT guests for 172.20 addresses host trying to access their internal addresses via the VPN?

  Thanks in advance.

  Here is the order of operations for NAT on the firewall:

  1 nat 0-list of access (free from nat)

  2. match the existing xlates

  3. match the static controls

  a. static NAT with no access list

  b. static PAT with no access list

  4. match orders nat

  a. nat [id] access-list (first match)

  b. nat [id] [address] [mask] (best match)

  i. If the ID is 0, create an xlate identity

  II. use global pool for dynamic NAT

  III. use global dynamic pool for PAT

  If you can try

  (1) a static NAT with an access list that will have priority on instruction of dynamic NAT

  (2) as you can see on 4A it uses first match with NAT and access list so theoretically Exchange autour should do the trick.

  I don't see any negative consequences? -Well Yes, you could lose all connectivity. I don't think that will happen, but I can't promise if you do absolutely not this after-hours.

• NATting for VPN traffic only

  I have a client with an ASA 5505 who has several networks, he tries to communicate via a VPN tunnel with a desktop remotely. One of the networks does not work because it is also used on the other side of the tunnel management interface, and none of both sides seem ready to re - IP their interior space.

  Their proposed solution is to NAT the contradictory network on this side to a different subnet firewall before passing through the tunnel. How to implement a NAT which only uses the VPN tunnel while the rest of the traffic that comes through this device of the United-NATted Nations?

  The network in question is 192.168.0.0/24. Their target you want the NAT is 172.16.0.0/24. Config of the SAA is attached.

  Hello

  Basically, the political dynamic configuration PAT should work to connect VPN L2L because the PAT political dynamics is processed before PAT/NAT dynamic configurations.

  Only NAT configurations that can replace this dynamic NAT of the policy are

  • NAT0 / exempt NAT configuration
  • Strategy static NAT/PAT
  • Public static NAT/PAT

  And because we have determined that the only problem is with the network 192.168.0.0/24 and since there is no static configuration NAT/PAT or static policy NAT/PAT, then PAT political dynamics should be applied. Unless some configurations NAT0 continues to cause problems.

  The best way to determine what rules are hit for specific traffic is to use the command "packet - trace" on the SAA

  Packet-trace entry inside tcp 192.168.0.100 12345 10.1.7.100 80

  For example to simulate an HTTP connection at random on the remote site

  This should tell us for example

  • Where the package would be sent
  • He would pass the ACL interface
  • What NAT would be applied
  • It would correspond to any configuration VPN L2L
  • and many others

  Then can you take a sample output from the command mentioned twice and copy/paste the second result here. I ask get exit twice because that where the actual VPN L2L negotiations would go through the first time that this command would only raise the L2L VPN while the second command could show already all the info of what actually passed to the package simulated.

  In addition, judging by the NAT format you chose (political dynamics PAT), I assume that only your site connects to the remote site? Given that the political dynamics PAT (or dynamic PAT) normal does not allow creating a two-way connection. Connections can be opened that from your site to the remote site (naturally return traffic through automatically because existing connections and translations)

• Host NAT clientless VPN access

  Hello

  I have an ASA 5520 with a DMZ server accessible from the internet and local network using the public IP (static NAT to the DMZ server). As VPN users can access this server using the address public IP send the addresses of public subnet to the remote users with split tunneling ACL. The problem is that we need Clientless Remote Access users for this server attacker still sound too and it does not work. It works just fine when Clientless Remote users access to the private address of the DMZ server. We all need to connect to this server again a public address for the code page for the web server.

  I can't use split tunnel for Clientless Remote users, and connection was apparently the ASA as the source for this traffic. Anyone know if it is possible or an idea of what can I test?

  Thank you

  Kind regards

  Unfortunately, this is not possible for clientless VPN, the SAA is the connection of transmission by proxy because it isn't a full VPN tunnel. Therefore, it can only proxy the connection on the actual address, and not the address using a NAT.

• Disable the NAT for VPN site-to-site

  Hello world

  I work in a company, and we had to make a VPN site-to site.

  Everything works fine, except that the packages sent to my site are translated, in other words: the firewall on the other site (site_B) see only the IP address of my firewall (Site_A).

  I tried to solve the problem, but without success, I think that natives of VPN packets is the problem.

  Hey Houari,.

  I suspect something with the order of your NATing statement which is:

  NAT (inside, outside) static static source NETWORK_OBJ_172.19.32.0_19 destination NETWORK_OBJ_192.168.67.0_24 NETWORK_OBJ_192.168.67.0_24 NETWORK_OBJ_172.19.32.0_19

  Can you please have this change applied to the ASA:

  No source (indoor, outdoor) nat static static NETWORK_OBJ_172.19.32.0_19 destination NETWORK_OBJ_192.168.67.0_24 NETWORK_OBJ_192.168.67.0_24 NETWORK_OBJ_172.19.32.0_19

  NAT (inside, outside) 1 static source NETWORK_OBJ_192.168.67.0_24 NETWORK_OBJ_192.168.67.0_24 static destination NETWORK_OBJ_172.19.32.0_19 NETWORK_OBJ_172.19.32.0_19

  Try and let me know how it goes.

  If she did not help, please put the output form a package tracer will shape your internal network to the remote VPN subnet with the release of «see the nat detail»

• ACL ASA5540 does not not for VPN access.

  I'm under code 8,03 and have a simple VPN L2L configured between two sites. It is in fact a test config in my lab, but I'm unable to restrict traffic using an ACL inside.

  I used the VPN Wizard to do the config initial and then added an Interior (out) ACL to restrict traffic once the tunnel rises.

  The encryption card is as follows:

  access extensive list ip 164.72.1.128 outside_1_cryptomap allow 255.255.255.240 host SunMed_pc

  Then I have an ACL to limit traffic to ping GHC_laptop, telnet to GHC_switch and denying the rest:

  inside_access_out list extended access allowed icmp host host SunMed_pc GHC_Laptop

  inside_access_out list extended access permit tcp host SunMed_pc host GHC_switch eq telnet

  inside_access_out deny ip extended access list a whole

  However SunMed_pc can also ping at GHC_switch and can FTP to GHC_laptop even if the 3rd entrance to deny any meter increases when I do this.

  I have attached a Word document that has the entire config with a screenshot showing the ACL and the shots.

  Should I configured incorrectly, or is ACL ACL actually does not work as expected?

  You can still keep all the IP for your acl interesting traffic. If you delete the sysopt, then you would write access in your acl 'inside_access' like you did above.

  If you are going to have dozens of tunnels l2l and will limit all, then I just remove the sysopt and use the acl interface.

  There is another option. You can leave the sysopt and use a vpn-filter. It is explained here and can be applied to l2l.

• Issue of NAT for VPN

  If I have a LAN or 10.1.1.0/24 and I want NAT all of the hosts in 192.168.1.0/24.  I really don't want to create the object for each unique host network, because it's just for a lot.  I just wanted to confirm by creating two objects then natting them must configure a NAT right one?

  network object obj - 10.1.1.0

  10.1.1.0 subnet 255.255.255.0

  !

  network object obj - 192.168.1.0

  subnet 192.168.1.0 255.255.255.0

  !

  NAT (inside, outside) source static obj - 10.1.1.0 obj - 192.168.1.0 statick "remotely" destination "at a distance".

  Now when the remote network need access to network 10.1.1.0/24 hosts they should just be able to access to?

  10.1.1.1 will map to 192.168.1.1

  10.1.1.2 will map to 192.168.1.2

• workspace with a nat for external access device

  I have installad workspace with just 1 gateway, it works well form my internal network. Now, I need to access from the internet. I do not have a load balancer, but just a firewall that can NAT my assresses international to a public address.

  I set my firewall to redirect all traffic from https://pubblic_address to the horizon: workspacegatewayIP:443 but when with a browser I point to https://pubblic_address I get:

  https://a3cadgateway.xyz.internal/SaaS/auth/login?dest=https :// a3cadgateway.xyz.internal:443/web

  What should I do to provide external access to the gateway? Please can someone season me how to configure my firewall?

  The important part is to page 37, what did you set up here? The internal or external URL?

• Limit bandwidth for VPN users

  Hi guys,.

  I use ASA Version 8.2 (1), I want to limit vpn users to use less bandwidth of my Interlink to access something on the inside of the network

  example: source vpn pool

  Destn: inside the network

  Please let me know how to achieve this with QOS config.

  Hello

  Probably the best would be to match groups of tunnel.

  class-map TG1-best-effort 

  match tunnel-group Tunnel-Group-1 

  match flow ip destination-address 

  Then this traffic in police policy-map and apply the service policy to the external interface (since you want to traffic police from your home). You can also use the pool for vpn access lists.

  For more details, please see:

• I need VPN gateway to gateway with NAT for several subnets, RV082

  I have a pair of RV082 routers and I would like to configure a gateway to gateway VPN tunnel, as described in a book, "How to configure a VPN tunnel that routes all traffic to the remote gateway," (name of file Small_business_router_tunnel_Branch_to_Main.doc).  I followed this recipe book and found that my while the main office has internet connectivity, the branch subnet is not an internet connection.

  Routing behaves as advertised, where all traffic goes to the seat.  However, the 192.168.1.0 subnet in the branch receives no internet connectivity.  I read in other posts that the main router will provide only NAT for the local subnet, not the Management Office subnet.  Is it possible to configure the RV082 router to provide NAT for all subnets?

  If this is not the case, what product Cisco will provide connectivity VPN Tunnel as well as the NAT for all subnets?  The RV082 can be used as part of the final solution or are my RV082s a wasted expense?

  Here is the configuration that I had put in place, (real IP and IKE keys are false).

  If you are running 4.x firmware on your RV082, you must add an additional Allow access rule for the Branch Office subnet (considered one of the multiple subnets in the main office) may have access to the internet. Note the firmware version has more details about it.

• 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.

• Can the NAT of ASA configuration for vpn local pool

  We have a group of tunnel remote ipsec, clients address pool use 172.18.33.0/24 which setup from command "ip local pool. The remote cliens must use full ipsec tunnel.

  Because of IP overlap or route number, we would like to NAT this local basin of 172.18.33.0 to 192.168.3.0 subnet when vpn users access certain servers or subnet via external interface of the ASA.  I have nat mapping address command from an interface to another interface of Armi. The pool local vpn is not behind any physical interface of the ASA. My question is can ASA policy NAT configuration for vpn local pool.  If so, how to set up this NAT.

  Thank you

  Haiying

  Elijah,

  NAT_VPNClients ip 172.18.33.0 access list allow 255.255.255.0 10.1.1.0 255.255.255.0

  public static 192.168.33.0 (external, outside) - NAT_VPNClients access list

  The above configuration will be NAT 172.18.33.0/24 to 192.168.33.0/24 when you go to 10.1.1.0/24 (assuming that 10.1.1.0/24 is your subnet of servers).

  To allow the ASA to redirect rewritten traffic the same interface in which he receive, you must also order:

  permit same-security-traffic intra-interface

• How to configure NAT for Hyper-V on laptop with wifi, wired and vpn connectivity

  Me, as I suspect a lot of people, I have a laptop with WiFi connection, cable connection and VPN connection (Cisco AnyConnect), which

  also uses a virtual adapter (activated when active). I searched for some time a way to be able to move to

  Hyper-V in VirtualBox. Blocker full for me is the need for a lot of my virtual machines to be able to connect to the

  Internet through 'the connection active' in the way that VirtualBox and VMWare Workstation/Player through their NAT feature.

  I'm not a networking wait, but after looking around, can't seem to find something that is simple enough for me to configure,

  with a minimum of resources, which allows me to connect a Hyper-V virtual network via a simple NAT device adapter

  all three potential network connections - most seem to not assume that one connection out of the machine, which of course does not

  me what I want.

  Three questions:

  1. is there a Windows application available that an adapter (like loopback) internal which acts as a real NAT device to one of the surfaces

  external access via the active network connections and through the Windows Firewall and any other antivirus, components etc. for

  the road to (i.e. behaves like a "normal app" inside Windows for internet access)? It would be the best option, because it would be

  "always there" when I run virtual machines

  2. display of my lack of knowledge around this feature, don't RRAS (and I know that this is not an option "minimum contact") allow you to

  Connect an internal network adapter to several external network adapters?

  3. on the Linux/OpenBSD various base/NAT routers, are everything that allow several external adapters and who are

  relatively easy to set up (by an independent expert of the network)?

  Really, we could do with this feature for Hyper-V on the desktop, but willing to work around him, if there is a way to at least the

  use virtual machines, once it is easy to install.

  Hello

  The question is more suited in the TechNet forums. So I would say you mention the link and send the request in this forum for better support.
