I use auto routing with Altium and I search a way to force routing a connector on Bottom layer (as I do PCB prototype myself, it easier to solder connector on Bottom side).
To do this, I create a room and place it on this component.
Then I create a rule on this room.
But, it doesn't work.
Can someone help me to achieve this?
Thanks

I think this is because you do not already have a ground plane below it? Also make sure your ground plane is on the correct net (ie, set the ground polygon to GND net). BTW, I just tested this using a "Solid Region" as my ground plane.
Hopefully I understood what you are trying to do.
You have to create a mechanical pair.
With a PCB open click Design Board Layers and Colors (Shortcut: L)
In the bottom left corner, you'll see a Layer Pairs Button. Click it.
Add your layer pairs together (like Mechanical 14 and Mechanical 30).
That's it.
Now when you switch components between layers, the items on the mechanical 14 will switch to mechanical 30 and vice versa.
I'll try and add some images and format this answer to be a bit more clear later on.

Almost all PCB layout programs assume that the board will be produced commercially, with plated-through holes, so the programs don't make any provision for single-layer designs.
However, you could place a solid fill on the component side copper, not connected to any net, around the connector (or perhaps over the whole board). This would force the program to connect to the connector on the bottom side.
For a simple board, you may find it best to route it manually, then you have full control of where the connections are made. Even with (perhaps especially with!) complex boards, I do a lot of manual routing.
