IKE SA negotiation is started as initiator, non-rekey

L1 Bithead

Hello :),

I have a problem with VPN from PA-220 to Azure. The logs show this information : "IKEv2 IKE SA negotiation is started as initiator, non-rekey. Initiated SA " 

Every change I made it always is this same error. Is there any way to resolve this issue ?



Thanks in advance

Hi @Lukaszm1 ,


The log you have shared doesn't contain any error. It indicates that FW is trying to negotiate Phase1. The key point here is that FW is starting the negotiation ("as initiator"), due to the nature of the IPsec the initiator will not log the real reason why negotiation is failing.


You can try to enable passive mode under the IKE Gateway advance options - this will force the firewall to act only as responder and waits for the Azure to trigger negotiation. That way you should see more "detailed" log what could be the reason for the unsuccessful negotiation. Note that in thi case you need to find a way to tell Azure to start first - either by sending traffic from azure to on-prem network or by any "azure troubleshooting commands".

Hi ,

Thanks for fast replay , i try this but still no luck,  It is also very strange i have this same configuration on different location and it works without any problems. 



After change the ike to passive i have this information in logs :




Hi @Lukaszm1 ,


These logs are not related to the VPN negotiation, but rather with configuration commit.AlexanderAstardzhiev_0-1620827089325.png


If you have enabled passive mode on the FW and you don't see anything else it probably means Azure is not even trying.

If you don't have a way to force Azure to start negotiation, you can disable again the passive mode and run packet capture for IKE packets on the FW. Under CLI run:
> debug ike pcap on (this will capture any ike packets so if you have other tunnel already running in this fw it will capture them as well)
> debug ike pcap view



Thanks again, I found what was the problem, I make a mistake in polices and there was a bad ip address on it to the azure ;/ . 

No it is working


Thanks !
