Adding a forum to my main menu headbar

[themeparkpovs]

I have wordpress installed on my root in my mysql. I installed phpbb on my /forum part of my website. How do I add a page on my menubar that says forum and have it go to mywebsite.com/forum from my root website of mywebsite.com.

My website: themeparkpovs.com

Forum: themeparkpovs.com/forum

Thanks! But how do I make the top of the forum redirect back to my original wordpress site of themeparkpovs.com?
