There is requirement for a customer that inbound traffic to IDCS URL (e.g. Access Token URL for OAuth2) in one tenancy needs to be routed through a Customer firewall in another OCI tenancy in the same region.
Is it possible to configure the tenancy1's IDCS IP:443 behind a public load balancer in tenancy2.
I think if we can configure it, the public load balancer can talk to IDCS URL via Service Gateway attached in Tenancy2's VCN.
Here is the flow in question: Oracle SaaS (tenancy3) > Tenancy2's IG > FW > public LB > Tenancy1's IDCS URL via SGW. Is that doable?
(all 3 OCI tenancies are in the same region).
Thank you.
