VPN Site to Site ASA

Recently, I set up a VPN from Site to Site using a Cisco ASA 5505 to a Cisco 2691 and works a lot but internet no longer works for clients behind the ASA. I know how to get online, but it disconnects the VPN. Can someone please advice to see what I've done wrong or Miss? I know that acl 110 blocks them but am breaking my head by trying different things.

Thanks in advance,

Hello

I guess that a number of things here:

First is your ASA is directly connected to the internet, and the VPN is happening via internet.

And also your users trying to access the internet are in the subnet 192.168.0.0 255.255.255.0.

If they are both true, then it looks like the problem is with your ACL of proxy/field of encryption.

Your crypto acl has a match any destination in this document, which is a bad habit when virtual private networks using site-to-site.

permit access ip 192.168.0.0 scope list outside_1_cryptomap 255.255.255.0 any

It's basically saying take whatever passing from 192.168.0.0/24 to any destination and to quantify through the vpn.

So which includes your internet traffic. Make sure that you are specific using src and dst systems int these ACLs.

i.e. outside_1_cryptomap list extended access permitted ip 192.168.0.0 255.255.255.0 192.168.1.0 255.255.255.0

Where 192.168.1.0/24 is the remote network on the 2691. This acl should then be reversed, one exact mirror on the other homologous (2961).

You must also match this acl with your not acl nat, to ensure that your internet traffic is natted, but vpn traffic is not.

The acl blocking traffic either, because you have not an acl interface all traffic inside will be allowed to default outside inside.

HTH let me know if there are problems.

  • Cisco ASA 5505 VPN Site to Site

    Hi all

    First post on the forums. I have worked with Cisco ASA 5505 for a few months and I recently bought a 2nd ASA to implement tunnel VPN Site to Site. It seems so simple in the number of videos watched on the internet. But when I did he surprise it did work for me... I've removed the tunnels, a number of times and tried to recreate. I use the VPN Wizard in the SMA to create the tunnel. Both the asa 5505 of are and have the same firmware even etc..

    I'd appreciate any help that can be directed to this problem please.  Slowly losing my mind

    Hello

    There are some clear problems I see on a quick glance. These are not related to the actual VPN configuration but rather the NAT configurations.

    All your configuration of NAT CLI format above are configured as manual NAT / double NAT in Section 1. This means that the appliance NAT configurations have been added to the same section of the NAT configurations and scheduling of the NAT inside this Section rules is the cause of the problem for the L2L VPN connection for some.

    Here are a few suggestions on what to change

    ASA1

    Minimal changes

    the object of the LAN network

    192.168.10.0 subnet 255.255.255.0

    being REMOTE-LAN network

    255.255.255.0 subnet 192.168.100.0

    NAT (inside, outside) 1 static source LAN LAN to static destination REMOTE - LAN LAN

    no nat source (indoor, outdoor) public static NETWORK_OBJ_192.168.10.0_24 NETWORK_OBJ_192.168.10.0_24 NETWORK_OBJ_192.168.100.0_24 NETWORK_OBJ_192.168.100.0_24 non-proxy-arp-search of route static destination

    That means foregoing is first of all create 'object' that contain the local LAN and remote LANs. Then, it creates a NAT0 rule and adds to the top rules NAT. (number 1). It is essentially of at least one of the problems preventing the VPN operation or traffic that cross.

    Finally, we remove the old rule that generated the ASDM. It would do the same thing if it has been moved to the top, but I generally find the creation of the 'object' with descriptive names easier on the eyes in the long term.

    Other suggestions

    These changes are not necessary with regard to the VPN L2L. Here are some suggestions how to clean a part of NAT configurations.

    PAT-SOURCE network object-group

    source networks internal PAT Description

    object-network 192.168.10.0 255.255.255.0

    object-network 192.168.20.0 255.255.255.0

    object-network 192.168.40.0 255.255.255.0

    NAT interface (it is, outside) the after-service automatic PAT-SOURCE dynamic source

    No source (indoor, outdoor) nat Dynamics one interface

    no nat (wireless, outdoors) source Dynamics one interface

    no nat (servers, outside) no matter what source dynamic interface

    The above configuration creates a "object-group" that lists all internal networks that you have dynamic PAT configured so far. It then uses the ' object-group ' in a command unique 'nat' to manage the dynamic PAT for all internal networks (with the exception of printers who had nothing at first). Then we remove the old PAT dynamic configurations.

    Contains the command "nat" "car after" because it moving this "nat" configuration to the bottom of the NAT rules. For this reason its less likely to cause problems in the future.

    network of the SERVERS object

    subnet 192.168.20.0 255.255.255.0

    network of the VPN-POOL object

    192.168.50.0 subnet 255.255.255.0

    NAT (servers, external) 2 static static source of destination of SERVERS SERVERS VPN-VPN-POOL

    no nat (servers, external) static source NETWORK_OBJ_192.168.20.0_24 NETWORK_OBJ_192.168.20.0_24 NETWORK_OBJ_192.168.50.0_24 NETWORK_OBJ_192.168.50.0_24 non-proxy-arp-search of route static destination

    The above configuration is supposed to create a NAT0 configuration for traffic between the network and the pool of Client VPN server. To my knowledge the old configuration that remove us is not used because the traffic would have matched PAT rule dynamic server yet rather than this rule which is later in the NAT configurations and would not be addressed.

    no nat source (indoor, outdoor) public static NETWORK_OBJ_192.168.10.0_24 NETWORK_OBJ_192.168.10.0_24 NETWORK_OBJ_192.168.1.0_24 NETWORK_OBJ_192.168.1.0_24 non-proxy-arp-search of route static destination

    It seems to me that network 192.168.1.0/24 is not configured from anywhere in your network. Therefore, the above 'nat' configuration seems useless, can be deleted. If I missed something and its use in then of course do not remove it.

    ASA2

    Minimal changes

    the object of the LAN network

    255.255.255.0 subnet 192.168.100.0

    being REMOTE-LAN network

    192.168.10.0 subnet 255.255.255.0

    NAT (inside, outside) 1 static source LAN LAN to static destination REMOTE - LAN LAN

    no nat source (indoor, outdoor) public static NETWORK_OBJ_192.168.100.0_24 NETWORK_OBJ_192.168.100.0_24 NETWORK_OBJ_192.168.10.0_24 NETWORK_OBJ_192.168.10.0_24 non-proxy-arp-search of route static destination

    That means foregoing is first of all create 'object' that contain the local LAN and remote LANs. Then, it creates a NAT0 rule and adds to the top rules NAT. (number 1). It is essentially of at least one of the problems preventing the VPN operation or traffic that cross.

    Finally, we remove the old rule that generated the ASDM.

    Other suggestions

    PAT-SOURCE network object-group

    object-network 192.168.100.0 255.255.255.0

    NAT interface (it is, outside) the after-service automatic PAT-SOURCE dynamic source

    No source (indoor, outdoor) nat Dynamics one interface

    The above configuration is supposed to do the same thing with the other ASA. Although given that this network contains only a single subnet it cleans the "nat" configurations exist that much. But the order of the "nat" configurations is changed to avoid further problems with the NAT order.

    no nat source (indoor, outdoor) public static NETWORK_OBJ_192.168.100.0_24 NETWORK_OBJ_192.168.100.0_24 NETWORK_OBJ_192.168.1.0_24 NETWORK_OBJ_192.168.1.0_24 non-proxy-arp-search of route static destination

    It seems to me that network 192.168.1.0/24 is not configured from anywhere in your network. Therefore, the above 'nat' configuration seems useless, can be deleted. If I missed something and its use in then of course do not remove it.

    I suggest trying the changes related to VPN L2L first NAT0 configurations and test traffic. So who gets the work of connectivity, then you could consider changing other NAT configurations. There are other things that could be changed also in what concerns THAT static NAT servers but that probably better left for another time.

    Hope this makes any sense and has helped

    On your config, you have all these commands but on your VPN config, you mix ikev1 and ikev2. You have also defined political different ikev2. Just do a bit of cleaning and reached agreement on a 1 strategy for the two site (encryption, hash,...)

  • VPN site to Site using the router and ASA

    Hello

    I have a Cisco 1812 router that is configured for remote access VPN using IPSec (Cisco VPN Client), my question is if I can configure a Cisco ASA 5505 to connect to the router as a VPN from site to site.

    Thank you

    Karl

    Dear Karl,

    Yor are right, in this case you can create a tunnel vpn site-to-site between devices or you can configure your ASA as hardware VPN client. That is to say; Easy VPN.

    For the same thing, you can consult the document below.

    http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/products_configuration_example09186a00808a61f4.shtml

    Kind regards

    Shijo.

  • Issue of ASA vpn site to site isakmp

    Hello

    He has been asked to configure on ASA a new vpn site-to-site. For that vpn should I put:

    crypto isakmp identity address
    crypto ISAKMP allow outside

    .. the configuration of my identity crypto isakmp is automatic and isakmp crypto is not enabled on any interface. I love vpn with ike enabled on the external interface. My question is: why should I enable isakmp on the external interface and especially can create disturbances to ike vpn that are already in place?

    By elsewhere-group or tunnel-group strategy, it was me asked to set up, the two do not have indication of ike. Never seen this kind of configuration before vpn, something new.

    Thank you

    Hi, Giuseppe.

    The crypto isakmp command activate outside changed ikev1 crypto Enable outside in the new ASA versions you need not enable this.

    There is also no need configure isakmp crypto identity address such that it is set to auto.

    This command indicates that the tunnel would be negotiated on the basis of the IP address but since it is set to auto it on it own will therefore not need to specify this command.

    Yes, you can create a new group policy group for this new tunnel and tunnel and there should be no impact on other tunnels of work.

    Kind regards

  • Cisco ASA VPN Site to Site WITH NAT inside

    Hello!

    I have 2 ASA 5505 related to IPSEC Tunnel VPN Site to Site.

    A 192.168.1.0/24 'remotely' inside the network and a local "192.168.200.0/24' inside the network (you can see the diagram)

    The local host have 192.168.200.254 as default gateway.

    I can't add static route to all army and I can't add static route to 192.168.200.254.

    NAT the VPN entering as 192.168.200.1 or a 192.168.200.x free to connect my host correcly?

    If my host sends packet to exit to the default gateway.

    Thank you for your support

    Best regards

    Marco

    The configuration must be applied on the SAA with the 192.168.200.0 subnet it is inside, there must be something like this:

    permit 192.168.1.0 ip access list VPN_NAT 255.255.255.0 192.168.200.0 255.255.255.0

    NAT (outside) X VPN_NAT outside access list

    Global (inside) X Y.Y.Y.Y (where the Y.Y.Y.Y) is the ip address

    If you have other traffic on the vpn through the tunnel that requires no nat, then you must add external nat exemption rules since these lines above obliges all traffic through the asa to have a nat statement.

    See if it works for you, else post your config nat here.

  • ASA 5505 <>ASA 5510 VPN Site to Site

    Try to configure a vpn site-to site beetween an ASA 5505 and a 5510. I can't get anything thrown, there are now debugging messages or the other. I must have done something wrong, I followed this paper: http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a0080950890.shtml but I can't make it work. Anyone can have a peek at my configs, maybe I forgot something.

    OK, if you go ahead and add this command to all two firewalls 'inside access management' and try to one side inside the 10.21.32.10 ping always nothing passing by?

  • cannot ping remote ip on ASA no firewall (VPN site to site on SAA) configired no proxy, icmp not inspect, no chance

    some help me

    (Q) ping remote ip unable on ASA is not Firewall not on pc (VPN site to site on SAA) configired no proxy, icmp not inspect, no chance

    Note - I can ping PC but not the same subnet ip on ASA2 L3

    PC---> > ASA1 - ASA2<>

    Hi Matt,

    Let me answer your question in two points:

    • You cannot ping an ASA on another interface other than the one where you are connected to the ASA of.

    For example, ASA1 and ASA2 are connected through their interfaces 'outside '. ASA1 (or any other device on the external interface) can not ping/access ASA2 on his (ASA2) within the interface. The only time wherever this can be substituted is a tunnel VPN with the command "access management" configured for other interface, for example management-access inside

    • Traffic ASA1 ping to a remote client behind ASA2 won't over the VPN tunnel and as such is not encrypted. That's because ASA1 will forward traffic based on its routing table that probably this way through its 'outside' interface Except that traffic is allowed with the ASA2 (using the ACL), it will fail.

    We can do on the routers of sourcing our ping to another interface, but it will not work on the SAA.

  • IPsec VPN site to site between router problem Cisco ASA. Help, please

    Hello community,

    I'm stuck in configuring VPN site to site between ASA (OS 9.1) and router Cisco IOS (IOS 15, 2 - 4.M4)

    Attachment is router configuration and ASA. I also include the router debug output.

    It seems that the two parties must isakmp missmatch configuration, but I have already disabled the KeepAlive parameters. I also turn off PFS setting on both sides. But it does not work. I have no idea on this problem.

    Please help me. Any help appreciated.

    Thank you

     
     

    I didn't look any further, but this may be a reason:

     crypto map mymap 1 ipsec-isakmp dynamic dyn1 

    The dynamic CM must always be the last sequence in a card encryption:

     no crypto map mymap 1 ipsec-isakmp dynamic dyn1 crypto map mymap 65000 ipsec-isakmp dynamic dyn1

    Try this first, then we can look further.

  • VPN Site to Site ASA (only happens with interesting traffic)

    Is anyway to get an ASA to VPN site-to-site ASA addition interesting traffic?  I need to keep this tunnel independently of traffic is anyway to do this?

    Unfortunately, no such feature has been developed on the SAA. You need to deceive the ASA with a host located in the "interesting" part of the network to constantly generate interesting traffic. Here are a few suggestions:

    -Use the IP SLA on a Cisco device

    -Perform a host TCP ping

    -Setting up a host of the site has press site B as a NTP source ASA

    Thank you for evaluating useful messages!

  • Microsoft l2tp IPSec VPN site to site ASA on top

    I have a specialized applications casino that requires end-to-end encryption. I'm under the stack of Microsoft IPSec l2tp between my XP machine and my Windows 2003 server on the LAN. Can I use the same type of protocol stack Microsoft l2tp IPSec between my XP machine and the Windows Server 2003 a branch on the SAA to site to site ASA VPN tunnel? The VPN site-to site ASA is a type of key Preshare IPSec VPN tunnelle traffic between our head office and a branch in distance.

    In other words, the ASA site-to-site IPSec VPN will allow Microsoft l2tp through IPSec encrypted traffic? My ACL tunnel would allow full IP access between site. Something like:

    name 192.168.100.0 TexasSubnet

    name 192.168.200.0 RenoSubnet

    IP TexasSubnet 255.255.255.0 RenoSubnet 255.255.255.0 allow Access-list extended nat_zero

    Hello

    Yes, the L2TP can be encapsulated in IPSEC as all other traffic.

    However, make sure that no NAT is performed on each end. L2TP is a default header protection which will see NAT as a falsification of package and reject it.

    See you soon,.

    Can someone help me configure VPN site to site on cisco asa 5540. The other end is seen configured dyndns and so should set up her counterpart with the host name.

    If the other end is a dynamic IP address, you must configure a dynamic map and then use in the encryption card

    See the following example.

  • Several VPN site to site on the same ASA

    I need to set up an IPSEC tunnel to allow a provider to the remote site printing to a printer on my network.  I intend to use an ASA 5520 to do this.  The architecture is fairly simple:

    [Remote]-[Remote FW] --[FW Local]-[Local routing]-[printer]

    The downside is that there is finally more than a seller who needs to do.  Each will have a different destination but mena there will be more than a VPN to ASA at my end.  It seems that the ASA 5520 can be supported more than a VPN site to site, but I need to assign an IP address for different endpoint in each tunnel?

    I searched and found no a design guide for the VPN site - to-many.  If so, I'd appreciate a pointer.

    You can do several tunnels VPN site to site.  As a general rule, you would have a card encryption applied to the interface in the face of internet.  Each crypto map entry has a sequence number. You simply have to create all the necessary configurations (tunnel-group for the remote peer IP, ACL to set interesting traffic, etc.) and increment the entry card crypto.

     Example: crypto map outside_map 1 match address s2s-VPN-1 crypto map outside_map 1 set pfs crypto map outside_map 1 set peer 1.2.3.4 crypto map outside_map 1 set transform-set ESP-3DES-SHA tunnel-group 1.2.3.4 type ipsec-l2l tunnel-group 1.2.3.4 ipsec-attributes  ikev1 pre-shared-key SomeSecureKey$ crypto map outside_map 2 match address s2s-VPN-2 crypto map outside_map 2 set pfs crypto map outside_map 2 set peer 4.5.6.7 crypto map outside_map 2 set transform-set ESP-3DES-SHA tunnel-group 4.5.6.7 type ipsec-l2l tunnel-group 4.5.6.7 ipsec-attributes ikev1 pre-shared-key SomeSecureKey2$

  • ASA 8.4 (1) source-nat over vpn site-to-site

    I'm setting up a tunnel vpn site-to-site and require nat for the local and remote side. The remote side will be nat to

    10.2.255.128/25 on their face before they reach our network, so I have to only source-nat our servers via the tunnel to them. Should I just do the static NAT, then let the whole subnet through the acl of valuable traffic as the config below? I don't think I should use twice a nat because I'm not trying to make the destination nat on the firewall. Servers with us will 10.2.255.128/25 and I would like to preserve it through the ASA.

    network of the ServerA object

    host 10.1.0.1

    NAT 10.2.255.1 static (inside, outside)

    network of the object server b

    host 10.1.0.2

    NAT 10.2.255.2 static (inside, outside)

    the object server c network

    host 10.1.0.3

    NAT 10.2.255.3 static (inside, outside)

    the LOCAL_SUBNET object-group network

    object-network 10.2.255.0 255.255.255.128

    the REMOTE_SUBNET object-group network

    object-network 10.2.255.128 255.255.255.128

    VPN_ACL list extended access permitted ip object-group LOCAL_SUBNET-group of objects REMOTE_SUBNET

    Thank you

    Your configuration is correct, but I have a few comments.  Remember that NAT occurs before the delivery of your servers will be translated into 10.2.255.2 and 10.2.255.3 and then sent through the tunnel, so your encryption field is correct.

    Is your internet firewall as well? What your servers out of the internet?  They will be translated to 10.2.255.2 and 10.2.255.3 and who will fail in internet routing is.  If these servers access the internet through the firewall, I would recommend a configuration like this for each of your servers:

    network of the ServerA_NAT object

    Home 10.2.255.1

    NAT static ServerA ServerA_NAT destination (indoor, outdoor) static source REMOTE_SUBNET REMOTE_SUBNET

    This will use destination basic NAT for traffic VPN and NAT everything to a public IP address for the internet traffic.  Of course, if this is not your internet connection firewall can do abstraction.

  • VPN site to Site ASA 5510 and 871 w / dynamic IP

    What is the best method of creating a VPN site-to site between an ASA 5510 and a router 871 where the 5510 has a static IP address and has 871, a dynamic IP address?

    My ASA is running ASA software version 7.0 (5) and I can't find how to create a tunnel for a dynamic IP address via the ASDM. I have currently a tunnel between these two arrangements in place, but it was done by specifying the remote IP address, even if it is dynamic.

    Any suggestions or pointers would be * very * appreciated.

    -Adam

    This can help but it does not show ASDM.

    I'm trying to create a vpn site-to site between Cisco ASA 5510 and OpenSwan Linux, after completing the configuration of part and came across the VPN tunnel but nothing passes through the tunnel.

    I use the software version 8.0 (4) on my firewall SAA, so doing any faces a problem like that.

    Appreciate your support

    Both bugs are for outgoing VPN traffic. But in your case, we saw 'read' County was '0' which means that ASA has not received any package of Linux in the VPN tunnel.
