Unable to Connect IPSec VPN Tunnel

L0 Member

Need assistance to connect a VPN IPSec Tunnel between PA and Cisco 4300 Series. Everything seems to be configured on both sides, but when I check logs on the PA-CLI, it shows this log:


IPsec-SA request for queued since no phase1 found
2022-11-17 10:49:19.353 -0600 [PNTF]: { 1: }: ====> PHASE-1 NEGOTIATION STARTED AS INITIATOR, MAIN MODE <====
====> Initiated SA:[500]-[500] cookie:e70d77589b7877bb:0000000000


Where Do I check for Phase 1? I think it is the IKE Gateways, which it is already configured.

Hello @yjimenez


thanks for posting in LIVEcommunity!


To me this looks like standard log when Firewall initiates phase 1 to remove peer. The fact that this says: "queued since no phase1 found" indicates this is a new session rather than configuration is missing. Is there any further log after this entry? If there is a response, then there should be logs indicating what phase 1 parameters were received from remote peer. If there is no response or traffic is blocked in between, this log entry will be repeated as PA tries to establish phase 1.


Regarding your question, yes the phase 1 configuration is under: "IKE Gateways".


Kind Regards

Also Cisco devices dont tend to bring up VPN tunnels unless told to do so, ie sending traffic, etc. I would try to ping something from one side of the tunnel to the other and see what happens.
