How to Setup RDS custom property when internal and external domain name space is different

Hi All

I am setting up RDS for customer

My internal domain name is domain.local and my external domain is domain.com

I came across below PowerShell cmdlets on some blogs because my internal and external name space are different

Set-RDSessionCollectionConfiguration –CollectionName QuickSessionCollection -CustomRdpProperty “use redirection server name:i:1 `n alternate full address:s:remote.domain.com”

In above command, remote.domain.com points to which host?

Is it pointing to RD Session Broker

OR

Pointing to RD Session Host servers

I am not sure what above command will do exactly ?

Any help will be highly appreciated

Thanks Best Regards Mahesh
