Any harms in opening up multiple ports in listening-state in the context of Nginx?

[Ajay Garg]

Hi All.

I have been trying to do url-based redirections, but as per
http://mailman.nginx.org/pipermail/nginx/2017-April/053443.html, there are
issues cropping up.
If the issues exist, then I will have to follow the

    one port for each proxy-url (constant "/" location)

approach, instead of

   one port for all proxy-urls, using multiple locations to do the mapping

approach.


So, if I indeed need to open multiple ports to public in listening-state,
is there any harm?


Thanks and Regards,
Ajay
