I am trying to setup an openwrt router to allow internal clients to access an internal server via it's external address (dyndns pointing back).
At first an RFC1918 was shown. After much configuration changes the RFC1918 error is no longer displayed when using the external link but now after configuring a port forward from the internal out to redirect back to the internal server, the base webpage for the server is shown.
This is not the expected behavior, configured on this server is reverse proxy to assign different subdomains to different running ports.
This proper behavior is seen when accessing the external link from an external device.
I'm not sure what or where the issue is and am needing some help.
