How to set up the next situation

bounce20112@domain.net =>> forwarded to bounce@domain.net
bounce20113@domain.net =>> forwarded to bounce@domain.net
....
....
bounce20748@domain.net =>> forwarded to bounce@domain.net

A alias should do the trick I think, but how to set this.

bounce*@domain.net =>> bounce@domain.net

thanks in advance
