relayd transparent don't work

[Thuban]

Hi,
I'm using relayd to check headers before serving my website with httpd.

I need to keep in httpd's logs the client IP address. So I try to use
the "transparent" keyword in relayd.conf, but in this case, relayd
doesn't work and I can't reach httpd.

Here is the **not working** relayd relevant configuration : 

                relay "tlsforward" {
                listen on $ext_ip port 443 tls
                protocol "https"
                transparent forward to <local> port 8443 check tcp
        }


here is the **working without transparent" relayd.conf : 

        table <local> { 127.0.0.1 }
        ext_ip = 192.168.1.66

        http protocol "http" {
                tcp { nodelay, sack, socket buffer 65536, backlog 100 }
                match response header set "Cache-Control" value 
"max-age=1814400"
                match request header remove "Proxy"
                match response header set "X-Xss-Protection" value "1; 
mode=block"
                match response header set "Frame-Options" value "SAMEORIGIN"
                match response header set "X-Frame-Options" value "SAMEORIGIN"
                return error
        }
        relay "www" {
                listen on $ext_ip port 80
                protocol "http"
                forward to 127.0.0.1 port 8080
        }

        http protocol "https" {
                tcp { nodelay, sack, socket buffer 65536, backlog 100 }
                match response header set "Cache-Control" value 
"max-age=1814400"
                match request header remove "Proxy"
                match response header set "X-Xss-Protection" value "1; 
mode=block"
                match header append "X-Forwarded-For" \
                        value "$REMOTE_ADDR"
                match header append "X-Forwarded-By" \
                        value "$SERVER_ADDR:$SERVER_PORT"
                return error
                pass
                tls { no client-renegotiation, cipher-server-preference }
        }

        relay "tlsforward" {
                listen on $ext_ip port 443 tls
                protocol "https"
                forward to <local> port 8443 check tcp
        }


Any advice?
