flange

Whack the flange with a hammer. It will crack and you will be able to pry it off. Save the lead ring that is inside the flange right now.

You need a couple strands of oakum and means to pack the oakum and melt and pour that molten lead. Then you need a tool to pack the lead in tight.

If you decide to go that route, come back and ask, because you will get several good answers.

Working with cast iron pipe, oakum, and molten lead is not really a job for a DIYer. You should hire a professional for this one.
