Hello Team,

I have configured ipsec vpn to on-prem cisco device using bgp.
The tunnel is up, am learing some routes from on-prem, the test subnet on gcp is learnt on the on-prem device as well.
Challenge is i have a specific prefix on-prem [10.185.15.76/32] that am advertising from the on-prem vpn device, and from logs seems gcp is learning the route,

{
“textPayload”: “Prefix 10.185.15.76/32 BPS attributes for nexthops 169.254.100.2: as_path_length: 1, origin: igp, med: 0, neighbor_asn: 650001, inter_region_cost: 0”,
“insertId”: “3xc2k6fcl1dyd”,
“resource”: {
“type”: “gce_router”,
“labels”: {
“project_id”: “ipsl-test-project”,
“router_id”: “1156198541993525687”,
“region”: “europe-west1”
}
},
“timestamp”: “2025-04-11T15:47:43.829798052Z”,
“severity”: “DEBUG”,
“logName”: “projects/ipsl-test-project/logs/compute.googleapis.com%2Frouter_events”,
“receiveTimestamp”: “2025-04-11T15:47:43.835238984Z”
}

However on the console for routes, this route is not available,

So when i trace traffic from a gcp vm to 10.185.15.76, it defaults to the internet default g/w.
why would be the case, what could be causing this?

ooh, realized its under suprressed routes. I dont know why?

and how comes port 22 to it works, but icmp does not, yet both are applied to the firewall?
