Is there a way to change the lifetime in seconds for Phase 1 and Phase 2 of Ipsec? I am trying to connect to a Cisco ASA 5550 at a customer site and their lifetime in seconds setting is 86,400(Phase 1) and 28,800(Phase 2). These need to match and I cannot adjust it on the Cisco side as their IT department will not alter it. From what I can find on the GCP the default settings are 36,000 and 10,800 and I cannot find any way to change this... Any help is appreciated.


As you know, with IKEv1 the configuration must match at both ends, and this is not configurable on the Google side. As a result, if you're not able to change the configuration of the peer, unfortunately you won't be able to configure Cloud VPN for use.
