Ports needed for just building

[chatlow]

Please could someone advise what ports will be used and needed just for just building of a new host please? I’m reading 8000 and 9090 would suffice a PXE build?

I think this diagram is a good resource.

This picture can also be viewed here and there is also a table which mentions for what each and every port is used
