Terraform-允许除特定端口之外的所有出站端口?

我在terraform中定义了这个AWS安全组:

resource "aws_security_group" "sg" {
  name = "${var.name}"
  description = "${var.description}"
  vpc_id = "${data.terraform_remote_state.vpc.vpc_id}"

  ingress {
    from_port   = 80
    to_port     = 80
    protocol    = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }

  ingress {
    from_port   = 443
    to_port     = 443
    protocol    = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }

  ingress {
    from_port   = 22
    to_port     = 22
    protocol    = "tcp"
    cidr_blocks = ["${var.ext_blocks}"]
  }

  egress {
    from_port       = 0
    to_port         = 0
    protocol        = "-1"
    cidr_blocks     = ["0.0.0.0/0"]
  }
}

通过这种配置,任何端口都可以用作出站/出站。但是如果我想排除一些端口,建议的方法是什么?

  egress {
    from_port       = 0
    to_port         = 24
    protocol        = "-1"
    cidr_blocks     = ["0.0.0.0/0"]
  }
  egress {
    from_port       = 26
    to_port         = 464
    protocol        = "-1"
    cidr_blocks     = ["0.0.0.0/0"]
  }
  egress {
    from_port       = 466
    to_port         = 65535
    protocol        = "-1"
    cidr_blocks     = ["0.0.0.0/0"]
  }

但这需要定义特定的范围,这需要定义一些额外的出口规则。有没有更好的办法?例如,我可以在哪里定义规则来允许所有端口,然后排除一些端口?
