• VPN IPSec passthrough ASA 5505 (v9.2.4) - connected but no access

  Hello

  Here's my situation:

  I am trying to connect a client IPSec VPN via an ASA 5505 to an other ASA 5505. In fact, I can make the connection to the VPN but all accesses are blocked (ping or IP access).

  When I use a router ISP directly or at home, I have no problem (ping and IP access follow the firewall rules). Connection and access are allowed.

  Schema:

  

  I have attached both the configuration for this post

  I've recently updated 8.2.5 ASA 8.4.6 and 9.2.4. An another ASA 5505 v8.2.5 works well in both way (via ASA VPN connection) and the VPN through ASA1 this ASA.

  I have tried many solution to solve the problem (nat/ipsec static inspection), but I failed to solve it. I tried to see asp in ASA1 drop, but I was right to drop only "nat-xlate-failed".

  Thanks for your help because I'm going crazy...

• IPSec VPN between Cisco ASA and Fortigate1000

  Hello

  I find a useful document on how to create a tunnel VPN IPSec with ASA 5510 firewall Fortigate 1000...

  the configuration of the coast FG is done without any problem, BUT the document (. doc FG) said I must configure the ASA with a GRE interface and assign an internal IP address in order to communicate with the FG...

  The question is: How do I configure the interface on the SAA ACCORD?

  Thanks in advance, Experts...

  Kind regards...

  ASA firewall does not support the interface/GRE GRE tunnel.

  If you need to have GRE configured, you will need to complete the GRE tunnel on router IOS.

  If you want to configure just pure tunnel VPN IPSec (lan-to-lan), here is an example of configuration on the side of the ASA:

• ASA 5505 - I can't create an IPSEC VPN between two ASA 5505

  Hello

  I have two ASA 5505 with basic license and I'm trying to create a VPN IPSEC using the CLI. Here are the steps I did:

  1 Configure ASA-1 (host name, vlan 1 and vlan 2).

  2. configure a static route

  3. create object network (local and remote)

  4. create the access list

  5. create ikev1 crypto

  6. create tunnel-group

  7 Configure nat

  and I repeat the steps above with the ASA but another change IP.

  Are to correct the above steps?

  Why can I not create an IPSEC VPN between devices?.

  No, you needn't. The ASA configuration is ok. Packet trace proved it. I think it can be a problem on the hosts. Please, check the firewall on the PC and try to put out of service, if it is running.

• Cisco VPN Client and Windows XP VPN Client IPSec to ASA

  I configured ASA for IPSec VPN via Cisco VPN Client and XP VPN client communications. I can connect successfully with Cisco VPN Client, but I get an error when connecting with the XP client. Debugging said "misconfigured groups and transport/tunneling mode" I know, they use different methods of transport and tunneling, and I think that I have configured both. Take a look at the config.

  PS a funny thing - when I connect with client VPN in Windows Server 2003, I have no error. The only difference is that client XP is behind an ADSL router and client server is directly connected to the Internet on one of its public IP of interfaces. NAT in the case of XP can cause problems?

  Hello

  For the Cisco VPN client, you would need a tunnel-group name configured on the ASA with a pre-shared key.

  Please see configuration below:

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00805734ae.shtml

  or

  http://tinyurl.com/5t67hd

  Please see the section of tunnel-group config of the SAA.

  There is a tunnel-group called "rtptacvpn" and a pre-shared key associated with it. This group name is used by the VPN Client Group name.

  So, you would need a specific tunnel-group name configured with a pre-shared key and use it on the Cisco VPN Client.

  Secondly, because you are behind a router ADSL, I'm sure that's configured for NAT. can you please activate NAT - T on your ASA.

  "crypto isakmp nat-traversal.

  Thirdly, change the transformation of the value

  raccess 1 set transform-set vpnclienttrans crypto dyn1 dynamic-map

  Let me know the result.

• ASA VPN IPSec: MTU or CFG error Question?

  Hello

  I have a strange problem... If I created a tunnel IPSec the ASA vs, it goes up but doesn't work if the package + / less 150 bytes... case of exceeded the size of the packets, the ASA didn't send to client IPSec; The size is related to the type of configured tunnels:

  IPSEC over UDP	123
  No transportation Tunnelling	115

  Debug icmp report always ping request and response but with packet sniffing on vlan outside don't see a response packet when I try with higher values than those appearing:

  The problem occurs with any Protocol (TCP, UDP, ICMP) and checking the configuration with other ASA found no differences.

  The SAA is a 5505 with fw 8.0 (4) and IPSec microcode CNlite-MC-IPSECm-HAND-2, 05.

  Thank you

  Arturo.

  This is much like the following bug:

  CSCsu26649    Big packages removed with enable configured ip-comp

  Can you confirm that you have 'enable ip-comp' in your config vpn file? If so, that que desactiver turn off and you should be ok.

  Better yet, go to 8.0 (5).

• ASA ASA from Site to Site VPN IPSec Tunnel

  Any help would be greatly appreciated...

  I have two devices Cisco ASA with a Site for the configuration of the tunnel VPN IPSec Site as follows: -.

  Site #1 - Cisco ASA running version 8.2 (1) with an internal range of 10.0.0.x/24

  Site #2 - Cisco ASA running version 8.2 (1) with an internal range of 10.1.1.x/24

  Site #1 is simple and has a dynamic NAT rule which translates all of the inside and the outside (public IP) of the SAA.

  Internet access works very well in all workstations of this site.  A static route is configured to redirect all traffic to a public router upstream.

  Site #2 is slightly more complicated; the Cisco ASA is configured with 10.1.1.254/24 as its interior IP address and 10.1.2.254/24 as its external IP address.  A dynamic NAT rule is configured to translate everything inside as the 10.1.2.254 (outside) address of the ASA.  A default static route is then configured to redirect all traffic to a Draytek device on 10.1.2.253.  This device then performs its own private Public NAT.  Again the Internet works fine all hosts inside the Cisco ASA (10.1.1.x)

  The IPSec tunnel is created with the networks local and remote endpoint as above (10.0.0.x/24) and (10.1.1.x/24).  The Draytek at the Site #2 device is configured with a form of DMZ that allows essentially ALL traffic toward the front directly on the external interface of the ASA (10.1.2.254).  The Phase 1 and Phase 2 negotiation of the tunnel ends correctly, and the tunnel is formed without any problem.  However, all traffic passing on networks ICMP does not end and the Syslog reports the following-

  It's the same for any form of traffic passing over the tunnel.  The ACL is configured to allow segments of LAN out to any destination.  At this point, I left scratching my head, as my original theory was to blame the Draytek, but after reading the documentation given to the DMZ host configuration, it appears this parameter is configured all traffic is simply forwarded to the IP address (in this case, the Cisco ASA interface outside).

  Anyone can shed light on a possible cause of this problem?

  Thank you

• How to establish a tunnel vpn ipsec using DNS with ASA 5505?

  Hello

  I m get a dynamic IP address public and what I m trying to do is establish a tunnnel remote vpn using IPSec, which I realize my provider but each time resets of sessions or ASA 5505 reset, I get a new public IP and I need to put the new IP address on the remote client, so I can establish the vpn...

  How can I establish a vpn ipsec using DNS?  For this scenario, the remote client vpn is a vpn phone, but it could be any vpn client.

  Private private Public IP IP IP

  PBX - Telephone (LAN) - ASA 5505-(Internet)-(router) Remote Site-(LAN) VPN-

  Kind regards!

  Ah ok I see, Yes in this case there is no that you can do other than request a static IP address from your ISP.

  Kind regards.

• Cisco ASA Site to Site VPN IPSEC and NAT question

  Hi people,

  I have a question about the two Site to Site VPN IPSEC and NAT. basically what I want to achieve is to do the following:

  ASA2 is at HQ and ASA1 is a remote site. I have no problem setting a static static is a Site to IPSEC VPN between sites. Guests residing in 10.1.0.0/16 are able to communicate with hosts in 192.168.1.0/24, but what I want is to configure the NAT with IPSEC VPN for this host to 10.1.0.0/16 will communicate with hosts in 192.168.1.0/24 with translated addresses

  Just an example:

  N2 host (10.1.0.1/16) contacted N1 192.168.1.5 with destination host say 10.23.1.5 No 192.168.1.5 (notice the last byte is the same in the present case,.5)

  The translation still for the rest of the communication (host pings ip destination host 10.23.1.6 N3 N2 not 192.168.1.6 new last byte is the same)

  It sounds a bit confusing to me, but I've seen this type of configuration before when I worked for the supplier of managed services where we have given our customers (Ipsec Site to Site VPN with NAT, don't know how it was setup)

  Basically we contact the customer via site-to-site VPN hosts but their real address were hidden and we used as translated address more high 10.23.1.0/24 instead of (real) 192.168.1.0/24, last byte must be the same.

  Grateful if someone can shed some light on this subject.

  Hello

  OK so went with the old format of NAT configuration

  It seems to me that you could do the following:

  • Configure the ASA1 with static NAT strategy
    • access-list L2LVPN-POLICYNAT allowed ip 192.168.1.0 255.255.255.0 10.1.0.0 255.255.0.0
    • public static 10.23.1.0 (inside, outside) access-list L2LVPN-POLICYNAT
  • Because the above is a static NAT of the policy, this means that the translation will be made only when the destination network is 10.1.0.0/16
  • If you have for example a PAT basic configuration to inside-> external traffic, the above NAT configuration and the custom of the actual configuration of PAT interfere with eachother
  • ASA2 side, you can normally configure NAT0 / NAT Exemption for the 10.1.0.0/16 network
    • Note of the INTERIOR-SHEEP access-list SHEEP L2LVPN
    • the permitted INSIDE SHEEP 10.1.0.0 ip access list 255.255.0.0 10.23.1.0 255.255.255.0
    • NAT (inside) 0-list of access to the INTERIOR-SHEEP
  • You will need to consider that your access-list defining the VPN encrypted L2L traffic must reflect the new NAT network
    • ASA1: allowed to access-list L2LVPN-ENCRYPTIONDOMAIN ip 10.23.1.0 255.255.255.0 10.1.0.0 255.255.0.0
    • ASA2: list L2LVPN-ENCRYPTIONDOMAIN allowed ip 10.1.0.0 access 255.255.0.0 10.23.1.0 255.255.255.0

  I could test this configuration to work tomorrow but I would like to know if it works.

  Please rate if this was helpful

• Remote access VPN VPN Ping from ASA clients

  I would like to know if it is normal to not being able to traceroute or ping for VPN clients connected from the ASA command line? The VPN client and the connection works well at the moment. I can't ping / connect to the VPN and vice versa internal hosts. I can't ping however the ASA VPN client IP address himself well. I'm so split tunnel but that seems to work correctly based on the determination of route I ran.

  Can I have an IKEv1 and IKEv2 for VPN IPSEC configuration? I try to keep the IKEv1 VPN for the legacy Cisco VPN client while I began to roll on the AnyConnect IKEv2 client. Just end up creating a new configuration of VPN for the AnyConnect VPN (easier)?

  What is the purpose of the injection of the route the other way around? It seems to be against intuitive. I was hoping it say for VPN DHCP pool 32 come to me so I would not add static routes on my heart to point to the ASA for these ranges. This ASA is reserved for the VPN firewall not this traffic is not normally head to it. Right now I have just the static route for the 24 I use in the DHCP pool on carrots. I have of course the possibility to redistribute the beach many other ways with EIGRP / OSPF / RIP it seems to me that RRI was a nice way to do, but it doesn't seem to be.

  It probably all comes from me probably do not understand exactly how bits to pass through the firewall to the actual machine of the VPN client. You see only not an interface layer 3 for part of the ASA in the tunnel, according to me, is part of what confuses me.

  Basically, I followed this guide and added split tunnel and aaa via RADIUS which seem to work well. I can't emphasize enough that for all intent and purposes, it seems that the VPN works as it should now. Wait for this time I broke it a few hours while I was playing with various other orders lol.

  Thank you

  Tim

  Reference:
  ASA 5505 (base right now, license #labgear) 9.2 (4) running

  It is normal to not be able to ping remote VPN clients to the ASA's.  To be able to do outside the ASA IP address must be included in the field of encryption, which is not normally.

  Yes, you can use IKEv1 and IKEv2 at the same time.  However if you change consider using SSL.  It is best taken in charge and less painful.

  If you choose to ignore this advice, then I would create a new IKEv2 VPN rather than modify the existing and then migrate users through him.

  The reverse route injection does exactly what you describe.  They appear as static routes on the SAA, you will then need to redistribute in any routing protocol you like.  I wouldn't normally use for traffic of users, but for the traffic of a site when managing more complex failover scenarios.

  I recommend to stick to the single 24 static road in your kernel.

• VPN ipsec and port 500

  Hello world

  I connected connection VPN IPSEC.

  Connection works fine.

  Here's the Setup program

  PC---R1---R2--R3---ISP---ASA

  I check on R3

  The R3 CBAC is configured.

  R3 # sh ip inspect sessions | 96.51.x.x Inc.
  65719DB4 (192.168.98.6:59936)-online (96.51.x.x:4500) SIS_OPEN udp session

  What vpn ipsec connection is established, it shows that it is plugged into the port 4500 not 500?

  What is default behavior?

  Initially when he formed theVPN connection it showed both udp, ports 500 and 4500.

  Concerning

  MAhesh

  It has NAT/PAT between R3 and ASA. like address (192.168.98.6) private IP allows you to configure the ipsec session.  IKE detects NAT/PAT exist in NAT - D payload. IKE uses UDP 4500 to negotiate ISAKMP rather than UDP 500. Subsequently, the ESP traffic is also encapsulated in UDP 4500, in this way it can cross the NAT/PAT safely.

  If this behavior is expected.

• IOS router VPN Client (easy VPN) IPsec with Anyconnect

  Hello

  I would like to set up my router IOS IPsec VPN Client and connect with any connect.
  Is it possible to configure an IPSec and SSL VPN Client on IOS router? I use for example a 1841.

  It would be perfect to give the user the choice of SSL or IPSec protocol. And the user needs that the Anyconnect Client.

  I think it's possible with a Cisco ASA. But I can also do this with an IOS router?

  Please let me know how if this is possible.

  Also is it true that the IOS routers are not affected to hear bug bleed? SSL VPN and SSL VPN with Anyconnect page is also save?

  http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/CIS...

  But I am in any way interested in using IPSec and SSL VPN on a router IOS...

  It's true - CCP does not yet offer the options to configure a VPN IPsec with IKEv2.

  The configuration guide (here) offers detailed advice and includes examples of configuration.

• Client VPN und Cisco asa 5505 tunnel work but no traffic

  Hi all

  I am new to this forum and Don t have a lot of experience with Cisco, so I hope I can get help from specialists.

  I have the following problem:

  I installed und konfigured ASA 5505 for use with vpn client. I would like to access the local network from outside through vpn.

  To test, I installed ASA 5505 with ADSL (pppoe) and tried to give access to the internal network.

  Of course whenever I have recive the supplier's different IP address, but it didn't is not a problem reconfigure in the vpn client.

  After the connection is established (vpn tunnel work) I can see my external network packets. But I Don t have any connection to the internal network.

  I erased my setup yesterday and tried to reconfigure ASA again. I didn t tested yesterday, because it was too late. And I know that I Don t have the authorization rule at present by the ACL. But I think I'm having the same problem again. (tunnel but no traffic).

  What I did wrong. Could someone let me know what I have to do today.

  With hope for your help Dimitri.

  ASA configuration after reset and basic configuration: works to the Internet from within the course.

  Hello

  Normally, you want a static public IP address on the ASA to allow it to receive connections from VPN clients (avoid to change the IP address all the time).

  If you connect via VPN, check the following:

  1. the tunnel is established:

  HS cry isa his

  Must say QM_IDLE or MM_ACTIVE

  2 traffic is flowing (encrypted/decrypted):

  HS cry ips its

  3. Enter the command:

  management-access inside

  And check if you can PING the inside ASA VPN client IP.

  4. check that the default gateway for the LAN internal ASA within intellectual property (or there is a road to the ASA to send traffic to the VPN clients).

• iPad VPN from Cisco ASA 5520

  Hello

  I'm trying to get my ipad to VPN to our Cisco ASA5520.

  I think I have all the correct settings on both ends (I am able to vpn to the asa using a cisco 871 as the remote client).

  I think that for some reason the client vpn on ipad is not even make the asa. My question is: How can I monitor the ASA logs to see if the same connection attempt and eventually find the failure?

  Thank you

  M

  try: -.

  Debug crypto ISAKMP

  Debug crypto ipsec

  Vpn-sessiondb SH remote control (to see if the client is connected)

  I have configured ipad for remote vpn client, the user could connect to the 5520 but why that I had to use the ip addresses to access, but I couldn't use internal dns names. try to understand that at this moment.

  It may be useful
