How to configure listeners for more than 50 ports in NLB


Access is performed using a private link in a configuration with two VPCs. NLB is specified as the connection destination of the private link, but it is a requirement that port 50 or more must be used. NLB listeners can't scale beyond 50. Is there any way to solve this?

The limit of 50 listeners on NLBs is a hard limit, so the only viable option, without major architectural changes, is to use multiple NLBs.
