When adding a link, select No Ingress for the hop that moves in the direction towards the connection that cannot be made.
For example, a PrivateLink connection from an on-prem node to a cloud node: the link points from the on-prem node to the cloud node. In this scenario the Hop1 Initiating network option is set to No ingress since the cloud deployment cannot connect to the on-prem nodes. However, if the link points from the cloud node to the on-prem node, then the Hop1 Target network is set to No ingress.
The same logic applies to bridge scenarios. Whatever system is directly behind the load balancer is where the ingress network is applied.
