RSS – modify feed address?

Ok – here’s the situation. I have my blog embedded into my webpage design.

See here: https://www.retrotravels.net/blog.html

At the present time, if someone who was interested in tracking the feed of my blog, their aggregator would have links to my blog itself and not the page listed above,

like so: https://www.retrotravels.net/blog/index.php

That’s a problem since I took out the blog header info, making it appear as a anonymous blog to those who open the index.php. Is there a way to have it so that those who sign up for the feed are redirected to the blog.html page rather than the index.php?

As you can see by my stumbling attempts to modify my style.css, I am new at this so any advice/help would be much appreciated. ??
