That's exactly what I use, but it doesn't seems to work :
# snip from httpd logs
test.yeuxdelibad.net 127.0.0.1 - - [09/Apr/2017:11:47:54 +0200] "GET /
HTTP/1.0" 200 0
Here is my full relayd.conf.
I tried to use "transparent" keyword but relay fail in this case.
# cat /etc/relayd.conf
table <local> { 127.0.0.1 }
ext_ip = 192.168.1.2
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"
match header append "X-Forwarded-For" \
value "$REMOTE_ADDR"
match header append "X-Forwarded-By" \
value "$SERVER_ADDR:$SERVER_PORT"
return error
}
relay "www" {
listen on $ext_ip port 80
protocol "http"
forward to <local> port 8080 check tcp
}
Regards.
