I have a mac running OS X server hosting a web page at subdomain.domain.ne(not real address) on port 176, that is acceable from outside my LAN. I have an Xcode automatic integration status page that is only available on port 80, which my ISP blocks. How can I make it so that people can go to my subdomain.domain.net which redirects to othersubdomain.domain.net:176( that part already works) show the locally hosted othersubdomain.domain.net:80
