VPN site to Site, Phase 2 is do not fit correctly and no connectivity

Hi all

I am facing a problem with configuring VPN from Site to Site of my HO one of the remote site.

My remote site got the subnet(192.168.10.0/24) LAN, we use also in HO. Remote site wish to access certain servers in HO 192.168.200.0/24&192.168.80.0/24.So we did a NAT policy distance from the ASA 192.168.10.0/24 subnet remote site to 192.168.175.0/24 translation site while reaching the end of the HO.

The VPN the two phases are coming, but not able to reach my iam connectivity. I can see are encapsulating the packets from the remote site and decapsulating in HO, but opposite side does not (i.e. no encapsulation at the end of HO) & no decapsulation at the end of remote site.

a question, I noted at the end of HO "sh crypto ipsec his" shows a different card is attached to it. This cryptomap we have for our remote access VPN is displayed in the ipsec his. Please see the configuration and the output below...

Tag crypto map: non-retail-VPN, seq num: 3, local addr: x.x.x.x

local ident (addr, mask, prot, port): (192.168.200.0/255.255.255.0/0/0)
Remote ident (addr, mask, prot, port): (192.168.175.0/255.255.255.0/0/0)
current_peer: x.x.x.x

I can see hits on my crypto access list, and the two phases are coming. kindly help to solve the problem...

Thanks in advance...

Hello

Clearly, the connection is managed by another card crypto bein.

Check those:

-Where your ASA rounting the destination network. (192.168.175.0 network)

-L' outgoing interface that uses the path has a card encryption? THAT IS "NON-RETAIL-VPN.

-If it is rounting to the wrong interface try reconfigure the route to this destination.

This is most likely your problem. Or at least one of them.

Rate if this can help.

    For IKEv2 configuration: (example config, you can change to encryption, group,...)

    -You must add the declaration of exemption nat (see previous answer).

    -set your encryption domain ACLs:

    access-list-TRAFFIC IPSEC allowed extended LOCAL REMOTE - LAN LAN ip

    -Set the Phase 1:

    Crypto ikev2 allow outside
    IKEv2 crypto policy 10
    3des encryption
    the sha md5 integrity
    Group 5
    FRP sha
    second life 86400

    -Set the Phase 2:

    Crypto ipsec ikev2 ipsec IKEV2-PROPOSAL
    Esp aes encryption protocol
    Esp integrity sha-1 protocol

    -set the Group of tunnel

    tunnel-group REMOTE-PUBLIC-IP type ipsec-l2l
    REMOTE-PUBLIC-IP tunnel-group ipsec-attributes
    IKEv2 authentication remote pre-shared-key cisco123


    IKEv2 authentication local pre-shared-key cisco123

    -Define the encryption card

    card crypto CRYPTOMAP 10 set ipsec ikev2-IKEV2-PROPOSAL
    CRYPTOMAP interface card crypto outside
    crypto isakmp identity address

    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,...)

    So far, I have had a prior configuration planned for this scenario, but I'm not very sure if the tunnel I created will work because I did not test it before with this scenario. I'll go next week on this project and hopefully get a solution of brainstorming you guys. Thanks in advance!

    Any ideas why this is?

    All my other site-to-site VPN work very well.

    Hey Kevin,

    If you are familiar with the console of the ASA, you can run him debugs below for more information on this issue.

    Hi all, I have two sites in central administration, I have a C2801 as hub and in the remote part, I have a C1861 as it is get the IP through ADSL, after I configured the two rtrs, all stages of phase 1 is complete, the next step, I get the IKMP_ERR_NO_RETRANS error, I read a lot of entries here , but none are like the one I have.

    Please check if I missed some in the configuration. Another thing is that in the same C2801 I got a VPN Client and other vpn site-to-site, with a fixed IP address and work perfect.

  • VPN site-to-site initiated in one direction

    Hello. We try to establish a VPN site-to site between two ASA firewalls, let's call them ASA1 and ASA2. Problem is that ASA1 cannot start the connection. ISAKMP of ASA1 packets reach ASA2, but removed by an unwritten rule.

    When ASA2 launches, everything is OK. And while the stream exists on ASA2, ASA1 use flow, so he can start VPN also.

    Here's the output of packet - trace on ASA2:

    How to interpret the values of phase 4, i.e. to find the rule that causes drops, based on the id and other data? There is no such id in HS to access lists.

    Any other ideas? Thank you very much.

    And an idea more :)

    Maybe you have something like this on ASA2:

    ?

    Hi Josh,.

    Around this deployment, you will not be able to ping or reach the other side because of the NAT, NATting is dynamically IP addresses, you must do the following:

    R! :

    no nat ip inside source list ADDRESSES interface Serial0/3/0 overload

    no standard ip access list ADDRESSES

    permit of 172.16.8.0 0.0.7.255

    IP extended access.list ADDRESSES_NAT

    refuse the 172.16.8.0 ip 0.0.7.255 172.16.40.0 0.0.7.255

    overload of IP nat inside source list ADDRESSES_NAT interface Serial0/3/0

    R3:

    no nat ip inside the overload of source list ADDRESSES interface Serial0/3/1

    no standard ip access list ADDRESSES

    172.16.40.0 permit 0.0.7.255

    ADDRESSES_NAT extended IP access list

    deny ip 172.16.40.0 0.0.7.255 172.16.8.0 0.0.7.255

    IP nat inside source list ADDRESSES Overload: NAT interface Serial0/3/1

    with this show commands you make to phase 1 and phase 2 is in place and work:

    -show crypto isakmp his

    -show crypto ipsec his

    I hope this helps!

    Please note and mark it as correct the helpful post!
