Comment 2 for bug 1335023

What I am not sure is a usecase of gateway IP out of the subnet. The use case described in this bug report is a possible case but I am not sure it is a special case or not. I don't have a good answer to this question so far and I don't see this use case in my personal experience. It is very special case, it sounds reasonable that neutron does not allow to specify a gateway IP out of the subnet. Does anyone have an answer?
