    It looks as though the branch office only has one subnet? If so, it is probably a class C subnet but to make sure, run ipconfig/all on a branch machine, get the subnet. It will be somehting like if it is a class c subnet. Anyway the subnet will remain the same for other ranges, the range will just change ie

    If it is a class c subnet that would be represented by

    if it is class b, that will be
