+==== tcp_accept_haproxy ====
+Enable the internal TCP stack to expect a PROXY-protocol-formatted header as the first message of the connection. Both the human-readable (v1) and binary-encoded (v2) variants of the protocol are supported. This option is typically useful if you are behind a TCP load-balancer, such as HAProxy or an AWS' ELB, and allows the load-balancer to provide connection information regarding the upstream client. This enables the use of IP-based ACLs, even behind a load-balancer.
+Please note that enabling this option will reject any inbound TCP connection that does not conform to the PROXY-protocol spec.
+Default value is **no**.
