Open ports to and from VDA (Source and Destination)



I´ve to check with this forum, so I´m really sure.

I have a multisession VDA, with only the vda installed on a Windows server 2019 and published it to multisession desktop.


No, Director, no MCS, no PVS. Only a VM in VMware.

Authentication is done by the Netscaler
2 Storefront servers


Is there any more or less ports that are requiered to be open on that VDA?

My informatino below with comments is based on this link from citrix:
