[graphviz-interest] different rankdir in a graph

Hello folks I hope I am posting in the right way.
I am new to this, and I would appreciate if somebody will have a minute to
point me in the right direction here.
I am trying to setup a network graph between two sites, Paris and Berlin,
but I want them to arrange like the paris site to have LR rankdir and
Berlin site to have RL rankdir, but it seems like I cannot apply rankdirs
to subgraphs. Most likely I am not doing it properly so could you please
give me a hint? Spent some time on google with other people having this
issue but none worked for me.

Below is my .dot file, attached current layout and desired layout

Thank you
