Is gcp https load-balancer Frontend can listen on port other than 443?

I need to listen on HTTPS - SSL on port other than 443, I don't see any way to do it.
the reason I don't use TCP load balancing is that the load balancer listen on SSL and the backend listen on HTTP (works great on AWS). any idea? enter image description here

Solution

  • It is not possible at the moment, constraint is listed in REST API reference documentation, see at https://cloud.google.com/compute/docs/reference/rest/v1/globalForwardingRules

    portRange string

    This field is used along with the target field for TargetHttpProxy, TargetHttpsProxy, TargetSslProxy, TargetTcpProxy, TargetVpnGateway, TargetPool, TargetInstance.

    Applicable only when IPProtocol is TCP, UDP, or SCTP, only packets addressed to ports in the specified range will be forwarded to target. Forwarding rules with the same [IPAddress, IPProtocol] pair must have disjoint port ranges.

    Some types of forwarding target have constraints on the acceptable ports:

    TargetHttpProxy: 80, 8080

    TargetHttpsProxy: 443

    TargetTcpProxy: 25, 43, 110, 143, 195, 443, 465, 587, 700, 993, 995, 1688, 1883, 5222

    TargetSslProxy: 25, 43, 110, 143, 195, 443, 465, 587, 700, 993, 995, 1688, 1883, 5222

    TargetVpnGateway: 500, 4500
