      I have 2 GCP VPCs (in 2 separate projects) which I've set up tunnels to. The tunnels work separately, but when both are connected, pfSense only advertises to the last neighbour it connected to.

      GCP #1 - ASN: 65201; VPC: 10.140.0.0/20
      GCP #2 - ASN: 65203; VPC: 10.150.0.0/20
      pfSense - ASN: 65202: LANs: 10.0.0.0/24; 192.168.100.0/24

      When I connect to GCP #1, I can see the dynamic routes show up there in the Routes section. When the connection to GCP #2 gets established, the routes disappear from #1 and appear in #2.

      Is it possible to set it up so that pfSense advetises routes to both tunnels?

        Figured it out - had to set a separate allow all Prefix List to each neighbour.
