Remove that line from your vagrant file as it will be overwritten in Homestead.configure(...) which is defined in scripts/Homestead.rb. Instead you want to edit Homestead.rb, look for the following lines

    # Configure Port Forwarding To The Box
    config.vm.network "forwarded_port", guest: 80, host: 8000
    config.vm.network "forwarded_port", guest: 3306, host: 33060
    config.vm.network "forwarded_port", guest: 5432, host: 54320

You sir are awesome! Thanks. One think I've found is that most documentation on vagrant and servers just assumes you know where to find the files they tell you to edit. This leaves newbies in the dark.

Thanks again!
