VMware Cloud Director 10.6
VMware Cloud Director 10.6.1
This is an expected behavior.
You cannot select application port profiles which contain a range of ports. Please visit the documentation Add an SNAT or a DNAT Rule to an NSX Edge Gateway in the VMware Cloud Director Service Provider Admin PortalVMware Cloud Director Tenant Portal
Make multiple Application Port Profile with only one Port, and make multiple DNAT rules with each Application Port Profile.
