Implemented PROXY v2 protocol (https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt) so that stratum can be run behind an haproxy instance. iptables/ipset still work if haproxy is run on local machine. if run on remote machine switch to using client_block_ipset() and periodically sync the ipset to the machine running haproxy. haproxy must be configured with send-proxy-v2, version 1 does not work
