Include outside page within wp page

Hello,

I am new to wp and running a test intallation to learn the basics and to see if wp will do what I need.

My current site is run with joomla and I have a page using a wrapper (joomla term) to display a page from another source.

This page is basically a login page to another service I use and including the page on my site is with permission.

I think I’d need to do this with a wp Page but I haven’t been able to find an answer of how to do this.

Any help would be appreciated.
