});
const subnet = new SubnetV2(this, 'Subnet', {
  vpc: myVpc,
  availabilityZone: 'eu-west-2a',

const natgw = new NatGateway(this, 'NatGW', {
  subnet: subnet,
  vpc: myVpc,
  connectivityType: NatConnectivityType.PRIVATE,
  privateIpAddress: '10.0.0.42',
});
new Route(this, 'NatGwRoute', {

  destination: '0.0.0.0/0',
  target: { gateway: natgw },
});
