Folks,
We are working on a VPN tunnel establishment from a Juniper firewall to a Palo Alto Firewall. The Juniper Firewall gives us the below error:
“Rejected an IKE packet on ethernet1/2 from w.x.y.z:500 to a.b.c.d:500 with cookies 13e5ee6b5ad69332 and 0000000000000000 because an initial Phase 1 packet arrived from an unrecognized peer gateway.”
a.b.c.d = Public IP of the Juniper box
w.x.y.z = Public IP of the Palo Alto.
The catch here is that the Palo Alto is in the Amazon but VPN tunnels from this Palo Alto to other Palo Alto's works fine.
We need some assistance to troubleshoot this issue.
Thanks,
N!!!!
