One option would be to make the SocketContext available from the WsSession, and then:

WsSession ws = ...
PeerInfo peer = ws.socketContext().remotePeer();

Are you using the Proxy Protocol in your app?

If using https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt then there's already support for it (it just needs to be enabled by turning it on the listener) and you get host and port info in the request headers X-Forwarded-For and X-Forwarded-Port (automatically added by Helidon). Note that the proxy protocol preamble is not optional, if enabled, then it must be present. If that's what you need, then it's already in 4.0.9.
