When establishing VPN tunnel for the first time and having troubles bringing it up you may need to enable debugging as well as checking its state on your appliance. IKE Peer: In most cases there are some issues with the other side if you are initiator. If you are a responder reverse the logic. It this particular scenario there was no routing issues and ISAKMP was enabled on the outside so at this point you need to start with basics.
As shown above in this particular enrollment we have 3 ikev1 policies: 10,20, ASA will perform top down approach to find the match between both end points. If none of them matches you may get an error message mentioned above.
It is a good time to also double check your interesting traffic to eliminate any phase 2 issues. In my scenario this was exactly what happened.
Even after exchanging VPN form with proposals the other end never configured their side which caused the problem initiating the tunnel. Adding the proper ikev1 policy authentication,ecryption,hash,group,lifetime to the list will fix the problem. I hope this has been informative to you and thanks for stopping by. If you are interested in different states for phase 1 I would strongly recommend visiting tunnelsup. No purpose of reinventing the wheel here.

If required by the remote peer, these parameters can be changed by implementing Custom IPsec Policies. If you want multiple MX's to connect to the same 3rd party VPN peer they will all have the same shared secret.
In the event the primary uplink fails, the VPN connection will use the secondary Internet uplink. Please reference our documentation for more information.
Review the event log for entries that indicate there has been a failure during phase 1 or 2 negotiation. Here is an example log entry of a phase 1 failure:. The steps listed below will assist in troubleshooting the issue. Error Solution: This can result from a mismatched phase 2 security association. Error Solution: This can result from mismatched subnets in the IPsec tunnel definitions, typically a mismatched subnet mask.

If the MX the remote peer is attempting to establish the tunnel to is running on a firmware version lower than Also check the IP address and ensure that it is a valid peer that has been added in Dashboard.
In attempting to begin the phase 1 negotiation to establish the tunnel, we did not receive a response back from the remote side. Error Solution: If some hosts are having issues sending traffic across the VPN tunnel and others cannot, it is most likely due to the packets from that client system are not being routed to the MX. The client system either has an incorrect gateway or an incorrect subnet mask. Ensure that the phase 2 lifetime is set identically on both peers.
The MX default is seconds, and the MX does not support data-based lifetimes. Please reference the following links for vendor specific configuration examples:.Kumbh rashi odia re
Within Dashboard, be sure to add the supernet in our example, If this is overlooked, then the VPN tunnel will fail to establish due to the mismatched subnets. Please note that MX appliances running firmware below version If IKEv2 is configured on the Google side, the tunnel will not function.

What information did you receive in regards to the Quick Mode proposal that's the problematic one, not the one for IKE, so ike-scan won't help you. In particular, if PFS is mentioned you need to add a DH group to the esp setting similar to the one for ike. I still didn't solved this I feel like I tried and check everything. You can try adding the vpnc log to your question, maybe we see something there.
But discussing the issue with the other party might be the better approach. Also note that you use an obsolete and insecure protocol to connect to your VPN.

The numbers 14 and 18 in the non-routine Notify response correlate to these settings. Usually this issue is not related to lifetime as this will auto negotiate to the lowest value between the ASA and the Remote peer. There are times when the Remote peer may not negotiate the lifetime which will present this message but this is rare. PFS tends to be the largest culprit of the issues with Phase 2. The easiest way to troubleshoot error 14 is to enable pfs as group2.
If the issue persists after testing PFS, then it is best to reach out to the other side and compare the settings for Encryption, Hash, PFS and Lifetime to make sure everything matches.
