Can virtual machine scale sets without inbound NAT rules

Hi Team,
I want to do loadbalance virtual machine scale sets to provide SFTP option with scalable capability. however, while trying with LB option on VMSS blade, inbound NAT rules will be created for each port pointed to each instance of VMSS instances. so Can we have one IP on loadblancer (e.g 192.168.1.33 (port - 23)) points to VMSS multiple instances internally.
Thanks
Manish

2022-04-15T23:31:31.84+00:00 Hello @Anonymous , As documented here Each virtual machine scale set must have at least one inbound NAT pool. This documentation explains how inbound NAT rules are added when VMSS scales out.

As the goal here is to achieve a scalable SFTP server. I am still looking into this scenario and will let you know if this can be achieved.

2022-05-21T14:23:30.94+00:00 Create a load balancer, create a front end ip 192.168.1.33 and create a backend pool, by selecting vmss in its backpool. create a load balancing rule, that has front port of 23 and back port(as you wish). Hope it solves your query/
