Relayd forward to multiple ports on one target host?

[Paul Pace]

Hello!

I have an OpenBSD server that hosts multiple services listening on 
various ports (some projects have their own web server, some projects 
require a reverse proxy, some projects just use httpd, etc.). This 
server receives requests via relayd on a different server. I was hoping 
to not insert relayd between every request to the host, but it's not the 
end of the world if this is the only viable solution while using relayd.

The requests to relayd go to domains (e.g., www.example.com, 
serviceone.example.com, servicetwo.example.com, etc.) for web services 
(ports 80 and 443), but I cannot figure out a way to specify a port on 
the target server to forward requests to when there are multiple ports 
(e.g., www is on port 80, serviceone is on port 8080, servicetwo is on 
port 44443, etc.). Running relayd -n does not report syntax errors when 
there are multiple forward to rules for the same target server with 
different ports in the relay block, but I can't find a way to specify 
which request should go to which port.

Thank you,

Paul
