policy based Ikev2 site to site VPN between Cisco router and Palo Alto

msdphi — Fri, 31 May 2024 19:29:21 GMT

we have a policy-based site-to-site VPN between cisco router and palo alto. But the tunnel goes down and doesn't come up after the IPsec lifetime is expired. And tunnel only comes up after sending traffic from cisco to palo alto and not the other way. When The devices under the Cisco LAN subnet(192.168.2.0/24) try to communicate with the server (under the PA LAN subnet, 10.1.1.0/24), the tunnel doesn't come up. DPD and lifetime are already configured on both the Cisco router and PA

Hello,

Setup a tunnel monitor, it should send a ping across the tunnel and see if its up, etc. This should keep the tunnel up/alive.

Regards,
