title: Can an ELB enforce TLS authentication?
body: <p>I am using <a href="https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-elasticloadbalancingv2-loadbalancer.html" rel="nofollow noreferrer">AWS::ElasticLoadBalancingV2::LoadBalancer</a> and we need to start using client certificates (i.e. mTLS / two-way TLS). Our ELB is terminating TLS connections and has a server side certificate.</p>
  <p>Can the ELB itself be configured to enforce client authentication (by giving it a certificate for example)?</p>
