[Xymon] xymonproxy

Hi, I've got the request to set up an additional XYmon server in our internet DMZ for external customers. Since all machines that would be displayed there are on our internal network I'd like to forward all statuses  from our internal XYmon server to the one in the DMZ and was thinking about xymonproxy. But I saw on the man page and in the config files that I can only use xymonproxy OR xymond. And xymonproxy would forward ALL data not only the data for some specific hosts. Has one of you a solution that he/she wants to share? TIA Torsten
