[graphviz-interest] different rankdir in a graph ( second mail sorry )

Posted a mail a few minutes ago and formgot to include my dot file. Copy of
it:

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
digraph  {
    rankdir=RL;
    subgraph cluster1 {
        style=dotted;
        rank=same;
        label = "Paris";
        parisgw1 [label="parisgw1",shape=rect]
        parisgw2 [label="parisgw2",shape=rect]
        VDFpgw1 [label="VDF",shape=rect]
        VDFpgw2 [label="VDF",shape=rect]
        l3pgw1 [label="l3",shape=rect]
        l3pgw2 [label="l3",shape=rect]
        parisgw1->{VDFpgw1 l3pgw1}
        parisgw2->{VDFpgw2 l3pgw2}
    }
    subgraph cluster2 {
        label = "Berlin";
        style=dotted;
        rank=same;
        berlingw1 [label="berlingw1",shape=rect]
        berlingw2 [label="berlingw2",shape=rect]
               orgbgw1 [label="org",shape=rect]
               orgbgw2 [label="org",shape=rect]
               colbgw1 [label="col",shape=rect]
               colbgw2 [label="col",shape=rect]
        berlingw1->{orgbgw1 colbgw1}
        berlingw2->{orgbgw2 colbgw2}
    }
    VDFpgw1->orgbgw1
[constraint=false,dir=both,color=Red,arrowsize=0.5,label="tun0",fontsize=12,fontname=mono];
    VDFpgw2->orgbgw1
[constraint=false,dir=both,color=Red,arrowsize=0.5,label="tun0",fontsize=12,fontname=mono];
    l3pgw1->orgbgw1
[constraint=false,dir=both,color=Red,arrowsize=0.5,label="tun0",fontsize=12,fontname=mono];
    l3pgw2->orgbgw1
[constraint=false,dir=both,color=Red,arrowsize=0.5,label="tun0",fontsize=12,fontname=mono];

}
