      Hi, I run three networks (separate sites) on pfsense and they are interconnected using ipsec. All network sites are accessible via Dynamic DNS entries (Cloudflare). Cloudflare settings are set to 2 minutes renewal, however, when there is an IP reset on one of the sites, Cloudflare updates automatically, however the Ip address as noted inside pfsense ipsec settings is NOT renewed immediately and therefore the connection goes down. Is there any way to force DNS cache purging or IP address updating for this to NOT go down ? Ideally I would have fixed Ips however, this is not possible with the various current service providers.
      Any idea is welcome here !

      thanks

      Chris
